Synthesis and characterization of acrylic rubber/silica hybrid composites prepared by sol-gel technique
Acrylic rubber (ACM, Nipol AR51, density at 25degC = 1100 kg/cm3, Mooney viscosity, ML1+4 at 100degC = 51) was obtained from Nippon Zeon Co. Ltd. (Tokyo, Japan). It was reported to have epoxy cure site and was made from ethyl acrylate monomer. Tetraethoxysilane (TEOS, density = 930 kg/m3) was procured from Acros Organics (USA). Tetrahydrofuran (THF, 99% pure) was purchased from Merck (India). The precipitated silica (Ultrasil VN3, particle size range = 40-100 nm, oil absorption = 2.4 g/kg, pH = 6) was supplied by Bayer AG (Germany). Benzoyl peroxide (BPO, 97% purity) was purchased from Aldrich Chemicals (USA). Hexamethylenediamine carbamate (HMDC, DIAK#1) was supplied by Nicco Corp. Ltd. (India). Ammonium benzoate (AmBz) was prepared in the laboratory by reacting ammonium hydroxide and benzoic acid in 1:1 molar ratio in a water bath at around 60degC for 30 min. The salt formation was confirmed by Fourier transform infrared spectroscopy as well as by studying its solubility. Deionized water and concentrated hydrochloric acid of laboratory grade were obtained from indigenous sources.
The desired amount of ACM was dissolved in THF solvent. A proportion of the rubber to solvent was maintained at about 1 : 10 all throughout the experiment to retain the uniform viscosity of the reaction medium. TEOS, deionized water, and concentrated HCl as catalyst, in the molar ratio of 1 : 2 : 0.06,15 were throughly mixed by vigorous stirring for 15 min and then the mixture was added to the rubber solution under stirring conditions at ambient temperature. The proportion of TEOS was from 0 to 50 wt % of the ACM. Beyond 50 wt % TEOS, macrophase separation occurred. The formulations used in this study are given in Table I. The precursor solution for preparing the composites was stirred for 30 min and then poured over a uniform and thoroughly cleaned glass plate. The initial evaporation of the solvent was carried out under controlled conditions for 24 h, and then, in the next phase, further evaporation for 4 days was allowed to remove the residual solvent and byproducts (water and ethanol). The optimum gelling time was taken when practically no weight variation of the hybrid composites was noticed. All the films were transparent in appearance. For comparison, composites were also prepared with precipitated silica up to 30 wt % of its loading (beyond which the resultant film lost its homogeneity). The precipitated silica was initially dried at 120degC for 24 h and then dispersed in the ACM solution. All the composite films with precipitated silica were opaque and completely white in color. To crosslink the rubber phase, curatives were added to the solvated rubber. The two different curatives systems used in this study were BPO and a mixed crosslinked system comprising AmBz and HMDC, following an earlier work on acrylic rubber in our laboratory.16 Optimization of the doses of different curatives (Table I) was carried out by studying the maximum gel content in THF.
Addition of curatives was made only after complete mixing of TEOS, water, and HCl with solvated ACM for 30 min. The crosslinkers were dispersed under ambient conditions and then stirred for another 30 min for homogenous mixing. The films were cast over a plain glass plate as before and kept for controlled solvent evaporation for 24 h. In the next phase, peroxide-containing composite films were kept in the oven at 70degC for 2 h for curing, whereas the samples having mixed crosslinked system were cured at 170degC for 30 min. The above cure times were optimized from the maximum gel content values. | train | 101002app20681 | [

Comparison of the effects of phenyl dichlorophosphate modified and unmodified β-iron(III) oxide hydroxide on the thermal, combustion, and mechanical properties of ethylene-vinyl acetate/magnesium hydroxide composites
Phenyl dichlorophosphate (PDCP), iron(III) chloride hexahydrate (FeCl3*6H2O), and tetrahydrofuran were purchased from Sinopharm Chemical Reagent Co., Ltd. These reagents were of analytical grade and were used without further purification. MH was kindly provided by KeYan Co. (Hefei, China). The EVA copolymer, containing 28 wt % VA, was supplied by Hanwha CO., Ltd. (Korea).
β-Fe(O)OH was prepared by a typical experiment,[10, 11] FeCl3 (0.487 g) was dissolved in distilled water (30 mL) under stirring. Then, the mixture was transferred to a 40-mL Teflon-lined autoclave. Hydrothermal synthesis was carried out in an oven at 110degC for 2 h. The products were collected by filtration, washed with distilled water and ethanol several times, and then dried in an oven at 60degC for 6 h.
Surface modification of β-Fe(O)OH was prepared by the mixture of 10 mL of PDCP with 1 g of β-Fe(O)OH. After it was shaken for a short time, the mixture was moved into a three-necked, round-bottom flask. Then, water (20 mL) was slowly added in to the three-necked, round-bottom flask at 10degC for 5 h. Thereafter, the product was filtered and washed with low-density polyethylene on a Soxhlet extractor for over 36 h. Finally, the particles were dried at 60degC in an oven for 24 h. The obtained particles were labeled β-Fe(O)OPDCP. | train | 101002app40112 | [

Catalytic Performance of Zeolite-Supported Vanadia in the Aerobic Oxidation of 5-hydroxymethylfurfural to 2,5-diformylfuran
5-Hydroxymethylfurfural (HMF; >99 %), acetonitrile (>=99.9 %), toluene (anhydrous, 99.8 %), α,α,α-trifluorotoluene (TFT) (>=99 %), N,N-dimethylformamide (DMF; >=99.9 %), ammonium metavanadate (>=99 %), oxalic acid (>=99 %), sodium nitrate (>=99 %), and anisole (99 %) were acquired from Sigma-Aldrich. Methyl isobutyl ketone (MIBK; > 2,5-Diformylfuran (DFF; 98 %) was supplied by ABCR GmbH & Co. Dioxygen (99.5 %) was purchased from Air Liquide, Denmark. All NH4-zeolites were obtained from Zeolyst International, USA. Vanadium oxide (99.8 %) was acquired from Chr. Gerner-Jensen. All chemicals were used as received.
Commercial NH4-ZSM-5 (Si/Al=15), NH4-beta (Si/Al=25), NH4-mordenite (Si/Al=10) and NH4-Y (Si/Al=12) zeolites were initially calcined at 550 degC for 5 h to obtain the H-ZSM-5, H-beta, H-mordenite, and H-Y supports, respectively.
Vanadia supported on zeolite catalysts with 1-10 wt % V2O5 were prepared by wet impregnation of the supports with vanadium oxalate solution, by a procedure adopted from the literature.44 In a typical experiment to prepare 3 wt % zeolite-supported vanadia catalyst, 1.75 mL of NH4VO3/oxalic acid aqueous solution (0.378 M, prepared from ammonium metavanadate and oxalic acid in the molar ratio 1:2 at 70 degC) was added to 1 g of the zeolite using an incipient wetness impregnation technique. Once the impregnation was completed, the solids were dried at 120 degC for 8 h and then calcined at 500 degC for 5 h. The catalysts were named according to the nominal V2O5 loading in wt % and the support.
For the preparation of the Na-beta support, 10 g of NH4-beta were suspended in 300 mL of 1 M aqueous solution of NaNO3. The mixture was heated to 80 degC and stirred for 1 hour. Afterwards, the zeolite was filtered and washed with distilled water. This procedure was repeated twice. Finally, the recovered Na-beta material was dried and then calcined at 500 degC for 5 h.

A Microsized Cagelike Sulfur/Carbon Composite for a Lithium/Sulfur Battery with Excellent Performance
Soluble phenolic resin was prepared by following the methods reported by Zhao et al.22 To synthesize MWCNT@mesoporous carbon, the ratio of the carbon source/template/surfactant was optimized, according to Nazar's group.10 In summary, F127 (1.6 g), ethanol (8.0 g), and 0.2 M HCl (1.0 g) were stirred for 2 h at 40 degC to afford a clear solution. Next, TEOS (2.08 g), MWCNTs (1.0 g), and a 20 wt % solution of resols in ethanol were added in sequence and stirred for another 5 h. The mixture was evaporated at room temperature and held for 24 h at 100 degC in an oven for thermo-polymerization. The as-synthesized product was carbonized in a furnace under an argon atmosphere at 900 degC for 300 min. The obtained sample was then washed with 10 wt % HF to remove silica.
At a weight ratio of 1:1, the MWCNT@MPC composite was mixed with sublimed sulfur under ball-milling for 6 h and then heated at 155 degC for 12 h in an argon atmosphere, resulting in the SC composite. For comparison, pristine S-MPC composite was also prepared by the same method as that described above. For both samples, the sulfur content was 50 wt %. | train | 101002cplu201402021 | [

Controlled Synthesis and High Oxidation Stability of Cobalt Nanoparticles Encapsulated in Mesoporous Silica using a Modified Stober Approach and a Pseudomorphic Transformation
Materials: Cobalt(II) nitrate hexahydrate (VWR Prolabo, 98 %), sodium borohydride (Sigma-Aldrich, 98 %), citric acid monohydrate (Sigma-Aldrich, 99.5 %), 3-aminopropyltriethoxysilane (APTES, Sigma-Aldrich, 99 %), tetraethylorthosilicate (TEOS, VWR Prolabo, 99.9 %), hexadecyltrimethylammonium bromide (CTAB, C19H42BrN, Sigma, >=98 %), poly(vinylpyrrolidone) PVP (Sigma-Aldrich, average mol. wt 40000), NaOH (Sigma-Aldrich, >=98 %), and EtOH (VWR, absolute 99.9 %) were used as received. Deionized water (18 MΩ cm) was used for all the preparations after deoxygenation.
Synthesis of the Co NPs: Citrate-stabilized Co NPs were prepared from classical NaBH4 reduction.56 In a typical synthesis, cobalt(II) nitrate hexahydrate (115.5 mg, 0.397 mmol) and citric acid monohydrate (83-167 mg, 0.397-0.793 mmol, 1-2 equiv.) were added to deoxygenated water (175 mL) under mechanical stirring. previously solubilized in cold water (5 mL) was quickly added to the vigorously stirred solution. The mixture turned black, which is indicative of reduced cobalt NP formation. In certain cases, PVP (600 mg) was added immediately after the introduction of NaBH4 to form PVP-stabilized Co NPs. Complete dissolution of the polymer occurred rapidly (<1 min).
Encapsulation of the Co NPs in Silica, Co@SiO2: Co@SiO2 were prepared by controlled growth of the silica shell on the Co NPs in an ethanol/water mixture according to a modified Stober method.16 After the in situ synthesis of the Co NPs, an ethanol solution (390-780 mL) containing APTES (77 μL, 0.331 mmol, 0.8 equiv.) and TEOS (881 μL, 3.97 mmol, 10 equiv.) was added to the NP solution. This one-pot reaction was allowed to proceed for 20 h before centrifuging and drying to isolate the silica-coated particles.
Synthesis of Cobalt-Mesoporous Silica NPs (Co@m-SiO2): Co@SiO2 were used as a silica source for the synthesis of Co@m-SiO2 by a PMT.40 The appropriate quantity of Co@SiO2 was dispersed into an alkaline solution containing CTAB. The molar composition of the system was 1:0.11:0.24:395:36 SiO2/CTAB/NaOH/H2O/EtOH. After 1 h of stirring at room temperature, the gel was put in an autoclave and heated at 100 degC for 24 h under static conditions. The final solid was recovered by centrifugation, washed with water, and dried at 80 degC for 12 h. The CTAB rod-like template was removed by thermal treatment under hydrogen in a programmed heated tubular oven before use. The temperature was initially increased from room temperature to 400 degC at a rate of 5 degC min-1, and the temperature kept for 4 h to remove the organic phase.
Synthesis of Co/SiO2: The cobalt-based reference catalyst Co/SiO2 was prepared by incipient wetness impregnation over a silica-based carrier (SBET = 241 m2 g-1, Vp = Subsequently, the impregnated catalyst was dried by direct heating of the sample from room temperature to 85 degC for one night. Finally, the catalyst was calcined at 420 degC in dry air for 4 h and activated by a reduction treatment under pure hydrogen. To achieve a Co loading of 12.7 wt.-%, two successive incipient wetness impregnations were realized (see the Supporting Information, Table S1 and Figures S1 and S2, for characterization). | train | 101002ejic201201429 | [

Enhanced thermoelectric performance of Ag0.8Pb18SbTe20 alloyed with Se
The Ag0.8Pb18SbTe20-xSex samples were prepared with tellurium (99.999% purity), lead (99.9%), antimony (99.999%), silver (99.9%), and selenium (99.95%) powders as sources, which were weighed according to the stoichiometric ratio. After being uniformly mixed in an agate mortar under argon protection inside a glove box, the mixtures were pressed into a disk with diameter of 10 mm and height of 4 mm. The pole-shaped samples were assembled for high-pressure synthesis. The Ag0.8Pb18SbTe20-xSex compounds were prepared in a cubic anvil high-pressure apparatus (SPD 6 x 1200T) with a sample chamber of 23 mm on an edge at 1200-1300 K and 4.0 GPa. The temperature and pressure were maintained for 20 min. After that, the electrical power for heating was cut off and the pressure was released. The pressure was estimated by the oil press load, which was calibrated by the pressure-induced phase transitions of bismuth, thallium, and barium metals. The temperature was estimated by the relationship of input heater power and temperature, which was measured by the platinum-rhodium thermocouples. | train | 101002pssa201127501 | [

Enhanced electrospray ionization mass spectrometric detection of hexamethylene triperoxide diamine (HMTD) after oxidation to tetramethylene diperoxide diamine dialdehyde (TMDDD) All chemicals used for synthesis were of reagent grade. Lithium acetate dihydrate (99.999%), acetic acid (99.99%) as well as the LC/MS grade acetonitrile were purchased from Sigma-Aldrich (St. Louis, MO, USA). Sodium acetate (99%; HPLC grade) was obtained from Acros Organics (Geel, Belgium). Ammonium acetate (LC/MS grade) was from Fisher Scientific (Fair Lawn, NJ, USA). Potassium acetate (analytical grade) was purchased from POCH (Gliwice, Poland). Milli-Q water was used throughout all the experiments. Standard solutions of HMTD and TMDDD were prepared daily in acetonitrile.
HMTD was prepared according to a published procedure.[24] A 25-mL round-bottomed flask was charged at 0 degC with 0.7 g of hexamethylenetetramine and 2.3 mL of 50% H2O2. The mixture was continuously mixed with a magnetic stirrer. After complete dissolution, citric acid (1.15 g) was added in four portions every 15 min. The mixture was left overnight while it was allowed to warm to room temperature. The white precipitate was filtered, thoroughly washed with water, and an approximately 100-mg fraction of the product was dried in a vacuum desiccator.
TMDDD was synthesized according to the procedure published by Wierzbicki et al.[24] with minor modifications. A portion of HMTD was dissolved in boiling (freshly distilled) n-butyl acetate (1:80 ratio). The solution was filtered into a three-necked flask equipped with a condenser, a thermometer and a capillary (1 mm diameter). This solution was purged with a stream (10-15 mL s-1) of oxygen at 120 degC for approximately 1 h until complete conversion of HMTD. The solution was allowed to cool to room temperature and white crystals were collected on the following day. The product was recrystallized from n-butyl acetate (yield 10%). | train | 101002rcm7385 | [

Synthesis of iron-containing nitrogen-doped titania by hydrothermal method and its photocatalytic activity
Fe co-doped TiO2-xNy was prepared by hydrothermal method, similar to that used for only N-doped TiO2 reported in a previous paper [19]. TiCl3 20 wt% aqueous solution was used as the titanium source, and hexamethylenetetramine (HMT) was used as nitrogen source. To co-dope Fe into the samples, FeCl2*4H2O was added to the starting materials. In a typical preparation, a 50 mL mixed aqueous solution of TiCl3, FeCl2*4H2O and hexamethylenetetramine (HMT) was first prepared, which contained 0.03 mol of metal ions and 0.06 mol of HMT. Then, the solution was transferred to a Teflon-lined stainless autoclave, and heated at 190 degC for 2 h. After that, precipitates were collected by centrifugation, and carefully washed with distilled water and acetone. Finally, the products were vacuum-dried at 60 degC overnight. | train | 101007s11164-011-0277-z | [

Selective oxidation of p-cymene catalyzed by VPO catalyst: Process performance and kinetics studies
Three distinctive standard methods were used to prepare the VPO catalyst precursors phase, VOHPO4*0.5H2O [14]. In the first method, the precursor was prepared in an aqueous medium by dissolving V2O5 (6.0 g; 33 mmol) in aqueous HCl (35%, 79 mL) and refluxing for 2 h. The H3PO4 (85%; 8.9 g; 78 mmol) was added and the solution refluxed for further 2 h. The solution was subsequently evaporated to dryness and the resulting solid was refluxed in water (20 mL H2O g-1 solid) for 1 h. It was then filtered hot, washed with warm water, and dried in air (110 degC, 16 h). The precursor prepared by this method is denoted P1.In the second method, the precursor was prepared in an organic medium, by adding V2O5 (11.8 g; 66 mmol) to isobutanol (250 mL). H3PO4 (85%; 16.4 g; 39 mmol) was then introduced and the whole mixture was refluxed for 16 h. The light blue suspension was then separated from the organic solution by filtration and washed with isobutanol (200 mL) and ethanol (150 mL, 100%). The resulting solid was refluxed in water (9 mL g-1 solid), filtered hot, and dried in air (110 degC, 16 h). The precursor prepared by this method is denoted P2. The third method precursor was prepared via the dihydrate compound VOPO4*2H2O. A mixture V2O5 (11.8 g; 66 mmol) and H3PO4 (85%; 115.5 g; 106 mmol) were refluxed in water (24 mL g-1 solid) for 8 h. The resulting VOPO4*2H2O was recovered by filtration and washed with a little water. Some of the VOPO4*2H2O (4.0 g; 20 mmol) was subsequently refluxed with isobutanol (80 mL) for 21 h, and the resulting solid was recovered by filtration and dried in air (110 degC, 16 h). The precursor prepared by this method is denoted P3. The precursors (P1, P2 and P3) were activated under N2 flow in the tube furnace at 550 degC for 4 h. They are denoted C1, C2 and C3, respectively. | train | 101016jcej201005016 | [

Comparative study of oxidation of benzyl alcohol: Influence of Cu-doped metal cation on nano ZnO catalytic activity
Pure ZnO was prepared through hydrolysis and oxidizing process. Zn(NO3)2 (1 mmol) dissolved in 100 mL of distilled water with continuous stirring. NaOH solution was added into the drop by drop until the pH of the solution became 12. The resulting white particles were washed three times with distilled water and dried for 24 h at 80 degC. At this point, the white product did not show high crystallinity since it consisted of ZnO and Zn(OH)2. Calcining at 500 degC for 1 h was necessary to obtain high crystalline ZnO [30].
Synthesis of CuxZn1-xO (1% Cu-doped) nanopowder was carried out using a modified procedure [23] and [24]. The targets were specifically designed using high purity Zn(NO3)2*6H2O (99.99%) and CuSO4*5H2O (99%) powders. The Cu-doped ZnO catalyst was prepared by a two-step procedure: (1) preparation of the precursor by co-precipitation; (2) formation of the Cu/ZnO nanopowder by thermal decomposition. This method has been considered to be efficient and inexpensive, allowing for the production of high purity, homogeneous, and fine crystalline powders.
Stoichiometric quantities of Zn and Cu salts were dissolved in 100 mL of deionized double distilled water (solution A). Separately, a solution was prepared by dissolving appropriate amounts of NaOH and Na2CO3 in deionized double distilled water (solution B). Solution A was heated to 85 degC and solution B was added dropwise into it with constant stirring. The temperature was maintained at 85 degC and the reaction mixture was stirred for 1 h and refluxed through a water condenser. The resulting solution was cooled to room temperature and the green precipitate that formed was washed with 3 x 20 mL of de-ionized water and dried under vacuum overnight at 50 degC. Finally, the precursors were calcined at 450 degC for 90 min in a muffle furnace under air atmosphere to obtain the nanocrystalline Cu/ZnO powder. | train | 101016jcej201504032 | [

Fabrication of conductive polymer-coated sulfur composite cathode materials based on layer-by-layer assembly for rechargeable lithium-sulfur batteries
Polyethyleneimine (PEI, Mw 50-100 kDa), poly(allylamine hydrochloride) (PAH) (Mw 70 kDa), poly(styrenesulfonate sodium salt) (PSS) (Mw 70 kDa), gultaraldehyde (GA) and the water-soluble polypyrrole (PPY) (5 wt% in water) doped with organic acid were purchased from Sigma-Aldrich. The aniline monomer was used with further purification by decompressed distillation and then stored at 0-5 degC. The water used in all experiments was prepared in a three-stage Millipore Milli-Q Plus 185 purification system and had a resistivity higher than 18.2 MΩ cm.
Sulfur particles were separately dispersed in PEI solution (1 mg/mL in 0.5 M NaCl) and allowed to adsorb for 30 min. Then excess polyelectrolytes were removed by centrifugation and three times washing with 0.5 M NaCl. Subsequently the above suspensions were alternately dispersed in PAH and PSS solution (2 mg/mL in 0.5 M NaCl) for another 30 min, followed by three times washing in 0.5 M NaCl. After the assembly of a desired number of PAH/PSS layer, the coated particles were then dispersed in 5% glutaraldehyde (GA) aqueous solution for 30 min. Finally these sample suspensions were incubated at the high temperature for 20 min.
In a typical procedure, the prepared polymer-coated sulfur particles aqueous dispersion was added into the aniline monomer solution mixed with 1 M hydrochloric acid (HCl) under stirring. After 30 min, the equivalent number of moles of 22.8 wt% aqueous ammonium persulphate (APS) solution (with respect to aniline) was slowly added, followed by an oxidative polymerization at 0-3 degC. The reaction was carried out for 24 h. The resultant green solid, PANI/polymer-coated sulfur particles, were obtained by centrifugation and washed with water and ethanol thoroughly to remove excess ions and monomers. The procedure was repeated to increase the PANI content. The final product was dried under vacuum at ambient temperature for 24 h. The whole experiments were performed under the nitrogen atmosphere. The conductive polypyrrole (PPY) shells were prepared through a electrostatic interaction of the negatively charged PPY on the positively charged outer shell of (PAH/PSS)n/PAH-coated sulfur particles. The resultant gray solid was dried for further characterization and testing. | train | 101016jcolsurfa201208033 | [

Characterization of mechanical and microstructural properties of palm oil fuel ash geopolymer cement paste
The palm oil fuel ash (POFA), obtained from burning of palm oil shells, husk and fibers, was collected from a mill at Johor State, south of Malaysia. The raw palm oil fuel ash was oven dried at 110 +- 5 degC for 24 h , sieved with a 300 μm sieve to remove large unwanted particles and incompletely combusted materials [49] and [50], and then it was ground by a modified Los Angeles machine [42]. The specific surface area after grinding was 0.915 m2/g. As can be seen, major components are SiO2 and CaO with concentrations of 47.37% and 11.83%, respectively with a low amount of Al2O3 (3.53%). The relatively high amount of CaO available in the POFA is most likely from lime and fertilizer [41]. It is worth to mention that POFA is a not toxic waste material in terms of heavy metals leachability [51].
Sodium hydroxide and sodium silicate were chosen as alkali activators in this investigation. The sodium hydroxide was in industrial-grade with minimum 99% purity. Industrial grade water glass (Na2SiO3) solution was chosen with a chemical composition of 15.33% Na2O, 31.28% SiO2, and 53% H2O. The alkaline activator selection was based on the recommendations in [34], [53], [54] and [55]. The alkali activation solution was prepared by mixing Na2SiO3 with NaOH within ratios ranged between 0.5 and 3.0 [34].
Preliminary experiments were conducted to study the alkali activation of POFA [56]. It revealed that raw POFA cannot be used without sieving and grinding because of the low compressive strength results which is related to the porous structure and high demands for the alkaline activator. Experimental program was designed in order to investigate the ability of POFA to be incorporated in geopolymer technology. NaOH solution was mixed with Na2SiO3 to produce six ratios (0.5, 1.0, 1.5, 2.0, 2.5, and 3) to prepare alkaline activator solution 24 h prior to use. Ground POFA and the alkaline activator were then mixed with two solid-to-liquid ratios (1.0, 1.32) as in [34], [53], [57] and [58]. Mix one with sodium silicate to sodium hydroxide ratio (0.5) was unable to be used; the geopolymer paste had such low workability that could not be cast in molds.
The palm oil fuel ash was mixed directly with the alkaline activator. First the ash was discharged to the mixer pan, and then the alkaline was added and mixed for 1.0 min at a normal speed rate (gear one). Then, the mixer stopped for 10-20 s in order to scrap the un-mixed ash on the sides of the paddle and the pan, then the mixing was continued with a medium speed (gear two) for another 1.0 min in accordance to ASTM C305 [59]. All the geopolymer paste mixes were blended and produced with a small blender (HOBART Mixer). The fresh geopolymer paste was then cast into 50 x 50 x 50 mm iron molds in two layers immediately after mixing. To compact the specimen, each layer was vibrated by a vibrating table for 25-30 s. This procedure was used to remove the bubbles from the paste. After casting and vibrating, oven curing was applied directly at 60 degC for 2 h. The molds were then kept in the laboratory to reach ambient temperature. The specimens were kept in a plastic bags after de-molding to prevent any moisture loss and were stored to the date of testing [55]. | train | 101016jconbuildmat201405031 | [

High catalytic activity of magnetic CuFe2O4/graphene oxide composite for the degradation of organic dyes under visible light irradiation
CuFe2O4/GO (20 wt%) was synthesized by a hydrothermal method. In a typical synthesis, 60 mg of GO was dispersed in 40 mL deionized water with sonication for 1 h. The mixture of 0.200 g Cu(CH3COO)2*H2O, 0.811 g Fe(NO3)3*9H2O and 20 ml deionized water was then added to GO aqueous solution dropwise and stirred for 1 h. The pH value of this suspension was adjusted to 10.0 using 6 M NaOH solution. After stirring for 30 min, the suspension solution was transferred into a 100 mL Teflon-lined stainless steel autoclave, sealed and intained at 220 degC for 18 h. The final products were centrifugated and dried in a vacuum oven at 60 degC. | train | 101016jcplett201608020 | [

Anthracene based organodisulfide positive active materials for lithium secondary battery
The ABTH was prepared following the methods in the literature [10] either from 1,4,5,8-tetrachloroanthracene (route 1 in Scheme 1) or from anthracene (route 2 in Scheme 1), the products were extracted with CS2 in Soxhlet's extractor for 24 h to remove free sulfur then with water-alcohol to remove soluble impurities. PABTH was polymerized simply by oxidative coupling reaction of ABTH in the presence of FeCl3 in chloroform at room temperature for 48 h. The polymer was dried at 60 degC in oven to constant weight. | train | 101016jelecom200308018 | [

Intrinsic electrochemical performance and precise control of surface porosity of graphene-modified electrodes using the drop-casting technique
Graphite and other chemicals were obtained from Sigma-Aldrich and are of reagent grade or higher. In the production of graphene, the first step was the oxidation of graphite to graphite oxide using the modified-Hummers method as reported in the literature [24] and [25]. The graphite oxide was subsequently thermally exfoliated at 1000 degC to give reduced graphene based on our previous method [26]. Graphene dispersions were prepared in DMF at concentrations ranging from 1.0 mg mL- 1 to 7.0 mg mL- 1, by ultrasonication for an initial 10 mins followed by 5 mins before each subsequent drop-casting event. | train | 101016jelecom201507001 | [

Significant influence of insufficient lithium on electrochemical performance of lithium-rich layered oxide cathodes for lithium ion batteries
Li[Li1/3-2x/3Mn2/3-x/3Nix]O2 (x = 0.3) was prepared in two steps: formation of transition-metal hydroxide (Ni0.35Mn0.65(OH)2) and subsequent solid phase reaction of Ni0.35Mn0.75(OH)2 and Li2CO3. Specially, 8.74 g MnSO4*H2O (99%) and 7.20 g NiSO4*6H2O (98%) were dissolved into 400 ml H2O under magnetic stirring, and 10 ml ammonia hydroxide was then added as chelating agent. After being kept at 60 degC for 10 min, 100 ml aqueous solution containing 6.4 g KOH (98%) was slowly dropped, and the precipitation reaction was kept for 24 h. The resulting precipitation was mixed completely with lithium carbonate (98%). In this mixing, the precursors with 10 wt% excess lithium (E10), 5 wt% excess lithium (E5), stoichiometric lithium (ST), and 5 wt% deficient lithium (D5) were used. Four samples were obtained by calcining the mixture at 900 degC for 12 h, denoted as 900E10, 900E5, 900ST, and 900D5, respectively. | train | 101016jelectacta201404084 | [

Li3V2(PO4)3/graphene nanocomposites with superior cycling performance as cathode materials for lithium ion batteries
In a typical synthesis, graphene oxide (GO) was prepared from natural graphite powder via a modified Hummers method [26] and [27].
Pure LVP was synthesized by using a sol-gel method reported in our previous paper [28]. First, oxalic acid (3.02 g) and V2O5 (1.46 g) in a stoichiometric ratio were dissolved in deionized water with magnetic stirring at 70 degC. After a clear blue solution formed, a mixture of stoichiometric NH4H2PO4 (1.84 g) and CH3COOLi*H2O (1.68 g) was added to the solution whilst stirring for 4 h, and then a gel formed in an air oven at 100 degC. The gel was decomposed at 350 degC in an argon atmosphere for 4 h, and the obtained product was ground, pressed into pellets, and sintered at 750 degC for 4 h in flowing argon. The sample was divided into two parts: one was further heated at 750 degC for 2 h in an argon atmosphere; the other was used to prepare LVP/G nanocomposites via a simple precipitation procedure, as described in detail as follows. The as-prepared LVP (1.0 g) was transferred to a suspension of 50 mg graphene oxide dissolved in 500 mL deionized water. The mixture was stirred for 12 h at room temperature after ultrasonic treatment for 2 h. Subsequently, the mixture was dried by freeze drying. Finally the dried sample was also sintered at 750 degC for 2 h in flowing argon. | train | 101016jelectacta201510036 | [

A stoichiometric aqueous mixture of Li2CO3 and (NH4)2HPO4 was prepared at the room temperature, while corresponded stoichiometric amount of TiCl4 was diluted in ethanol. The TiCl4 solution was added dropwisely into the aqueous mixture with stirring at room temperature, which induced a gelatinous precipitate. The resulting solution was stirred overnight and then evaporated the solvent at 80 degC under vacuum. The dried white precipitate was calcinated in air at 400 degC for 5 h and then at 850 degC for 12 h with a heating rate of 1 degC min-1.
A measured amount (0.4 g) of PVDF was dissolved into 10 mL of N-methylpyrrolidone (NMP) and then 2.0 g of LiTiOPO4 was dispersed into the formed solution with stirring for 2 h. The mixture was dried to remove solvent at 80 degC under vacuum and subsequently calcinated in Ar atmosphere at 650 degC for 3 h with a heating rate of 1 degC min-1. | train | 101016jelectacta201510124 | [

A simple method to synthesize V 2 O 5 nanostructures with controllable morphology for high performance Li-ion batteries
V2O5 nanomaterials were synthesized using solid-state chemical reaction methods. All the reagents were analytically pure from commercial sources and used without further purification. Typical synthesis for V2O5 nanostructures was as follows. Solid ammonium metavanadate (NH4VO3, AR, >99%) and tartaric acid (C4H6O6, AR, >99%) with a molar ratio of 1:2, and polyethylene glycol 4000 (PEG-4000, AR, >99%) were apart weighed and ground in an agate mortar for about 5 min to ensure the evenness of starting materials, then mixed. Then the reactants were mixed, and the color of mixture changed from white to yellow. After grind for 30 min at room temperature, the color of mixture changed from yellow to grey. The obtained sample was washed with absolute ethanol, and then dried at 60 degC for 10 h. Finally pure grey precursor (NH4)2[(VO)(C4H4O6)2] was got. Then the precursor was placed in muffle furnace at different calcination temperature of 400 degC, 500 degC, 600 degC for 4 h (1 degC min-1) to obtain final products. | train | 101016jelectacta201611160 | [

The commercial elemental powders of Cu (99.99%), Fe (99.99%) and S (99.9%) were used as starting materials. These powders were mixed according to the compositions of CuFeS2-x (x = 0, 0.05, 0.15, 0.20, 0.25), and the mixtures were subjected to MA in a planetary ball mill (QM-2L) using a hardened stainless steel vial and ball, which was performed at 450 rpm for different times. The weight ratio of balls to powders was kept at about 20:1, and the mill vial was filled with Ar (99.9%) atmosphere to prevent the powders from oxidation during the milling process. The MA-derived powders were densified by SPS at different temperatures ranging from 873 to 923 K for 5 min under an axial pressure of 50 MPa. Graphite dies were used for SPS, which was conducted in vacuum. | train | 101016jjallcom201209067 | [

Microwave-assisted hydrothermal synthesis of electrochemically active nano-sized Li2MnO3 dispersed on carbon nanotube network for lithium ion batteries
Electrochemically active Li2MnO3/CNT nanocomposite was successfully synthesized by MAH process. The detailed synthesis procedure of MnO2-coated CNT composite through redox reaction is described elsewhere [15]. A 0.1 M of KMnO4 solution and 1.0 g of CNT in double jacket vessel were heated to 70 degC using circulator (FP40, Julabo), and the mixture was maintained at same temperature for 12 h. The black suspension was filtered, washed, and then dried at 100 degC in oven. The LMO/CNT nanocomposite was prepared using MnO2-coated CNT composite with appropriate amount of different concentration of aqueous LiOH solution (0.1 M, 0.2 M, 0.5 M, and 1 M). These solution mixtures were rapidly heated to 200 degC in MAH reactor (MARS, CEM Corp.), maintained at 200 degC for (30 min), and cooled down to room temperature. The suspension was filtered, washed repeatedly with distilled water, and dried at 100 degC for 24 h in oven. The four different samples of LMO/CNT nanocomposites are named as shown in Table 1. | train | 101016jjallcom201312206 | [

Self-assembled graphene-wrapped SnO2 nanotubes nanohybrid as a high-performance anode material for lithium-ion batteries
The Sn nanorod templates were prepared via a simple NaBH4 reduction process using SnCl4 as a reactant and poly(diallyldimethylammonium chloride) (PDDA) as a soft template according to the previous report [41]. Then, the SnO2-NTs/G nanohybrid was synthesized through a facile electrostatic attraction directed self-assembly approach using Sn nanorods as templates. Typically, the pristine Sn nanorods and graphene oxide (GO) sheets (4:1 by weight) were dispersed in distilled water, stirred for 12 h, and then the GO matrix was reduced by NaBH4 (weight ratio of 10:1 for NaBH4/GO). After the reaction was finished, the resulting product was washed with distilled water and ethanol, yielding the SnO2-NTs/G nanohybrid. | train | 101016jjallcom201412037 | [

Synthesis of lanthanide doped CeF3:Gd3+, Sm3+ nanoparticles, exhibiting altered luminescence after hydrothermal post-treatment
The syntheses were carried out to produce 0.75 g of the product. NH4F (50% excess) was dissolved in 25 mL of water (solution A). An aqueous solution B was prepared that contained Ln(NO3)3 and CeCl3 which were mixed at the desired molar ratio (0.01 Sm(NO3)3, 0.15 Gd(NO3)3 and 0.84 CeCl3 mol%), and diluted with water to make 100 mL. In the case of the products obtained in the presence of EDTA and citric acid, 0.5 wt.% of the desired polycarboxylic acid was additionally dissolved in solutions A and B. The pH of the systems was adjusted to [?]7, by the use of an aqueous NaOH solution. Solution B was added dropwise to solution A, resulting in the precipitation of the lanthanide doped fluorides (LnF3). The reaction was performed at 343 K, with continuous stirring. Afterward the as-prepared products were divided into two parts. Half of the product was purified by centrifugation and washed several times with water. After this the product was dried overnight in the oven (at 358 K). The rest of the colloidal precipitate was transferred into a Teflon vessel and hydrothermally treated for 2 h, at 453 K/40 bar (microwave autoclave - ERTEC, Magnum II, 600 W). When the reaction was finished, the product obtained under hydrothermal conditions was purified by centrifugation and dried in the oven, as well. | train | 101016jjallcom201511182 | [

Catalytic performance of sheet-like Fe/ZSM-5 zeolites for the selective oxidation of benzene with nitrous oxide
Fe/ZSM-5 zeolite nanosheets were prepared according to a literature procedure modified with the purpose of including Fe3+[25] and [26]. In a typical synthesis, 10.42 g of TEOS (tetraethylorthosilicate) was added to a solution containing 0.47 g of aluminum nitrate nonahydrate, 0.06 g of iron nitrate nonahydrate, and 20.0 g of distilled water. The mixture was stirred for 2 h. A solution containing 2.41 g of C16-6-6(Br)2 or C16-6-6(OH)2, 0.42 g sodium hydroxide (NaOH) and 15.7 g of demi-water was added to this mixture and shaken by hand for 5 min. After further stirring with a magnetic stirrer for 6 h at room temperature, the gel mixture was transferred to a Teflon-lined stainless-steel autoclave and heated at 140 degC for 9 days under tumbling (60 rpm). The zeolite product was filtered, washed with distilled water, and dried at 100 degC overnight. Using the OH form of the template, three different Si/Fe ratios were employed (Si/Fe = 84, 180 and 300). The as-synthesized zeolites were calcined at 580 degC for 4 h under a flow of air. The calcined samples were ion-exchanged into their ammonium form by triple ion-exchange with a 1 M aqueous solution of NH4NO3 at room temperature. The proton form of the zeolites was obtained by calcination at 550 degC under a flow of air for 4 h. The samples are denoted as Fe/ZSM-5-sheet(x, y) with x the anion of the template used (OH or Br) and y the Si/Fe ratio. Steam activation was carried out by heating an amount of sample in a flow of 10% water vapor (100 ml min-1) in artificial air at 700 degC for 3 h. The steamed samples are denoted by using the suffix "-st." A reference Fe/ZSM-5 catalyst was prepared by controlled hydrolysis of TEOS in the presence of tetrapropylammonium hydroxide (TPAOH) according to a literature procedure [10]. | train | 101016jjcat201212002 | [

A controlled anion exchange strategy to synthesize core-shell β-bismuth oxide/bismuth sulfide hollow heterostructures with enhanced visible-light photocatalytic activity
All chemical reagents in our experiments were analytical and used as received without further purification. The synthesis of β-Bi2O3 hollow spheres adopted our previous method [21]. In a typical experiment, Bi(NO3)3*5H2O (2.91 g, 6 mmol) was dissolved in a mixed solution of glycerol (30 mL) and ethanol (30 mL) under vigorous stirring. After 40 min of stirring, the solution was transferred to a 100 mL Teflon-lined stainless steel autoclave, heated to 160 degC and maintained for 3 h. After the autoclave was cooled to room temperature, the products were separated centrifugally and washed with deionized water and absolute ethanol for several times, and then dried under vacuum at 80 degC overnight. Finally, the products were further heated at 2 degC/min heating rate from room temperature to 270 degC and maintained at 270 degC for 2 h to obtain β-Bi2O3 hollow spheres.
The core/shell β-Bi2O3/Bi2S3 hollow heterostructure was synthesized by in situ anion-exchange method. In a typical process, the as-prepared β-Bi2O3 hollow microsphere (0.4660 g, 1 mmol) was dispersed in 50 mL deionized water under vigorous stirring. Then a certain amount CH3CSNH2 (0.0225 g, 0.3 mmol) was added into the solution. After 30 min of stirring at 50 degC, the precipitates were collected, washed and dried under vacuum at 80 degC for 6 h. By controlling the theoretical molar percentage of Bi2S3 to initial Bi2O3, different β-Bi2O3/Bi2S3 heterostructures were obtained. The final samples were labeled as the β-Bi2O3/Bi2S3 (5%, 10%, 25%) heterostructure. | train | 101016jjcis201408027 | [

Carbon microspheres via microwave-assisted synthesis as counter electrodes of dye-sensitized solar cells
CSs were prepared using the method reported in our previous works [36]. In briefly, 6.846 g sucrose and 2 g concentrated sulfuric acid were dissolved in 100 ml mixing solvent of water and ethylene glycol (6:4 v/v). Subsequently, 20 ml of the solution was heated at 160 degC with a microwave irradiation power of 100 W for 10 min using a microwave system (Explorer-48, CEM Co.). After being centrifuged and washed with deionized water, the resultant precipitate was dried in a vacuum oven at 80 degC for 24 h and finally thermally treated at different temperatures for 2 h in nitrogen. In this work, CSs with different thermal temperatures of 600, 800 and 1000 degC are named as CS600, CS800 and CS1000, respectively. The as-synthesized CSs were deposited on F-doped SnO2 (FTO) (resistivity: 14 Ω/#, Nippon Sheet Glass, Japan) glass by screen printing. The as-prepared counter electrodes were sintered at 400 degC for 30 min. The conventional Pt film was also used as counter electrodes for comparison. | train | 101016jjcis201501016 | [

Low pressure preparation of spherical Si@C@CNT@C anode material for lithium-ion batteries
Spherical Si@C@CNT@C multiple composite was prepared from Si powder. Si powder was put in a chamber and vacuumed for 1 h. After that, 100 mL, 500 g L-1 glucose solution was added and the mixture was pyrolyzed at 650 degC for 5 h in an argon atmosphere. The obtained product was crushed to form Si@C composite and soaked in 0.5 mol L-1 Co(NO3)2 solution for 10 min. Then, the sample was filtrated and coated with CNT at 650 degC for 30 min by chemical vapor deposition (CVD) using acetylene as carbon source. The as-prepared Si@C@CNT was put in the vacuum chamber and vacuumed for 1 h. To form spherical Si@C@CNT@C multiple composite, 10 g pitch was acted as the carbon source for outer layer. The as-obtained sample was pyrolyzed at 800 degC for 5 h in an argon atmosphere and then crushed into smaller particles and granulated by ball-milling. The final product was obtained after a washing by water to remove the dust. | train | 101016jjelechem201405031 | [

Electrochemical lithium storage kinetics of self-organized nanochannel niobium oxide electrodes
Oriented nanochannel Nb2O5 films were prepared by electrochemical anodization of Nb foils (99.8% purity, Alfa Aesar). The anodization process was performed in a 10 wt.% K2HPO4 containing glycerol solution with a Pt counter electrode. The Nb foils were biased at 10 and 20 V for 5-25 min at 180 degC to produce nanoporous films with thicknesses ranging from 7 to 18 μm. After electrochemical anodization, the as-prepared films were cleaned with distilled water several times. The Nb2O5 films on Nb substrates were heated to 440 degC in air at a heating rate of 1 degC min-1. After annealing at 440 degC for 20 min, the furnace was cooled to room temperature automatically. | train | 101016jjelechem201503033 | [

Influence of non-stoichiometry on solid-state reactive sintering of YAG transparent ceramics
Y3(1+x)Al5O12 ceramics with x changed from -4.3% to 4.7% were fabricated by a solid-state reaction method from commercial α-Al2O3 (99.98%, Alfa Aesar, Tianjin, China) and Y2O3 (99.999%, Alfa Aesar, Tianjin, China) powders. The powders were mixed in ethanol and ball-milled with high-purity corundum balls in Al2O3 jars for 10 h with 0.08 wt% MgO powder (99.998%, Alfa Aesar) and 0.8 wt% tetraethoxysilane (TEOS, >99.999%, Alfa Aesar) as sintering aids. The slurry with the solid loading of 1.8 g/ml was dried at 80 degC for 4 h in an oven and then sieved through a 200-mesh screen with the screen pore size of ~74 μm, the powder mixture was calcined at 600 degC for 4 h to remove the organic components. After that the powder mixture was uniaxially pressed into 20 mm diameter pellets and then the green bodies were compacted by cold isostatic pressing (CIP) at 250 MPa. The compacted pellets were then sintered at 1500-1750 degC under vacuum (10-3 Pa) for up to 50 h in a tungsten mesh-heated vacuum furnace. The heating rate was 5 degC/min, and the cooling rate was 10 degC/min. After sintering, the specimens were annealed at 1450 degC for 10 h in air to remove oxygen vacancies. The samples were mirror polished on both surfaces with different grade of the diamond slurries. The polished specimens were thermally etched at 1400 degC or 1500 degC for 3 h to expose the grain boundaries. | train | 101016jjeurceramsoc201504038 | [

Synthesis and electrochemical properties of LiNi0.8Co0.2O2 nanopowders for lithium ion battery applications
Nitrates of lithium, cobalt and nickel are utilized to synthesize LiNi0.8Co0.2O2 cathode material through sol-gel technique. Various synthesis parameters such as calcination time and temperature as well as chelating agent are studied to determine the optimized condition for material processing. Using TG/DTA techniques, the optimized calcination temperatures are selected. Different characterization techniques such as ICP, XRD and TEM are employed to characterize the chemical composition, crystal structure, size and morphology of the powders. Micron and nano-sized powders are produced using citric/oxalic and TEA as chelating agent, respectively. Selected powders are used as cathode material to assemble batteries. Charge-discharge testing of these batteries show that the highest discharge capacity is 173 mAh g-1 at a constant current of 0.1 mA cm-2, between 3.0 and 4.2 V. This is obtained in a battery assembled with the nanopowder produced by TEA as chelating agent. The stoichiometric values of lithium, nickel and cobalt nitrate salts in a cationic ratio of Li:Ni:Co equal to 1:0.8:0.2 were dissolved in distilled water. Three chelating agents including triethanolamine (TEA), citric acid, oxalic acid are used in this investigation. These agents were used in a molar ratio of 1 with respect to the total metal cations by dissolving in distilled water. The solution was then added to the nitrate solution and was heated under constant stirring at 80 degC for 1 h. The resulting sol was heated at 100 degC to form the gel which was dried subsequently. To remove the moisture and achieve the dried mass, the obtained gel was successively dried at 100, 120, 150, 200 degC for 2 h per each step and 5 h at 240 degC. The thermal behavior of LiNi0.8Co0.2O2 powders was determined by thermogravimetric/differential thermal analysis (TG/DTA) conducted on the dried gel at a heating rate of 5 degC min-1 up to 1100 degC in the air using a Perkin Elmer analyzer. The tests were conducted in the air using alumina pans. The initial sample weights for TEA, oxalic and citric were 460, 250 and 290 mg, respectively. The dried mass was heated at 500, 600, 700, 800 and 900 degC for varying durations and slowly cooled to room temperature. Inductively coupled plasma (ICP) analysis was performed using an ARL 3410 unit to confirm the stoichiometry of lithium, nickel and cobalt in the synthesized powders. The resulting powders had molar ratios of Li: Ni:Co in the order of 1:0.8:0.2, respectively. | train | 101016jjpowsour201006097 | [

Effect of oxygen partial pressure on the electrochemical impedance of La0.8Sr0.2MnO3-δ/Zr0.92Y0.08O2 porous composite anodes in solid oxide electrolysis cell
The La0.8Sr0.2MnO3-δ was synthesized by a solid-state reaction method. Firstly, the appropriate ratios of Lanthanum nitrate (La(NO3)3*6H2O, AR), strontium carbonate (SrCO3, AR), manganous carbonate (MnCO3, AR) were thoroughly mixed with alcohol using a ball mill. Subsequently, the alcohol was removed by heating the slurry at 120 degC in air for 12 h. Next, the resulting dry powder was then calcined at 1000 degC for 6 h in air. The obtained powders were ground, milled and finally sifted through 300 mesh. Finally the LSM powders were mixed with the YSZ (TZ-8Y, Tosoh Corporation, Japan) powders at a mass ratio of LSM/YSZ = | train | 101016jjpowsour201202061 | [

The SnO2 nanospheres were synthesized by hydrothermal reaction of K2SnO3 in an aqueous glucose solution followed by calcination at 400 degC in air [18]. The SnO2 supported Pd catalyst was prepared through reduction of Na2PdCl4 with NaBH4. In a typical procedure, 50 mg of SnO2 was dispersed in 50 mL of water by sonication. Then, 2 mL of Na2PdCl4 solution (0.06 mM) was added, and the mixture was stirred for 1 h. A freshly prepared 10 mL of NaBH4 solution (0.1 M) was added to the solution at 0 degC, followed by stirring at room temperature overnight. Finally, it was filtered, washed with water and ethanol, and vacuum-dried at 70 degC for 6 h. | train | 101016jjpowsour201205003 | [

Silicon oxide-on-graphite planar composite synthesized using a microwave-assisted coating method for use as a fast-charging lithium-ion battery anode
Si oxide-coated graphite flake (SGF) is synthesized by a microwave-heating method.
To prepare the Si-containing liquid precursor, 19 g of polymethylhydrosiloxane (Aldrich) was mixed with 1 g of divinyl polydimethylsiloxane (Aldrich) and 0.25 g of a catalyst solution (1wt.% hydrogen hexachloroplatinate in isopropyl alcohol), and the resulting mixture was heated at 70 degC for 2 h. Graphitic flake (GF; KS6, Timcal) powder, which consisted of flakes having an average particle size of 3 μm (vender's value) and thicknesses ranging from 50 to 100 nm, was added into the liquid precursor and stirred for 1 h. The suspension was then filtered to collect solution-coated GFs. The wet GF powder was placed in an evacuated glass vessel and heated in a commercial microwave oven (Panasonic, NN-ST651; power setting: low-300 W) for 15 min. After the heating process, the powder was washed with hexane to remove residual precursors and then finally calcined at 1000 degC under vacuum for 1 h in a quartz tube furnace to obtain the SGFs. | train | 101016jjpowsour201507066 | [

Carbon-coated silicon nanotube arrays on carbon cloth as a hybrid anode for lithium-ion batteries
Silicon nanotubes were fabricated by using ZnO nanowire as a sacrificial template [18]. Typically, CC substrates (W0S1002, Phychemi Company Limited) were cut into small pieces (1-2 cm2), and then cleaned by sonication sequentially in acetone and alcohol for 10 min, respectively. The cleaned CC was then soaked in 0.0025 M zinc acetate dihydrate alcohol solution for 5 min and annealed in oven for 20 min at 300 degC to form a ZnO seed layer. A precursor 150 ml solution was prepared with 0.04 M zinc acetate dihydrate, 0.04 M hexamethylenetetramine and 0.009 M poly(ethylene imine). After preheating the precursor solution for 1 h at 95 degC, the seeded CC substrates were dipped into the solution for another 4 h and finally ZnO nanowire arrays were grown on the substrates. Subsequently, the substrates with ZnO nanowires were cleaned by deionized water and transferred into a chemical vapor deposition chamber to deposit a silicon shell. The deposition of silicon shell was achieved at 500 degC for several min with passing 4 sccm SiH4 and 20 sccm Ar at a pressure of 100 Pa. To form a carbon coating on the surface of silicon shell, another deposition process was carried out at 650 degC for 90 min with passing 4 sccm C2H2 and 20 sccm Ar at a pressure of 500 Pa. Finally, the core ZnO nanowires were selectively removed via a reduction process at 600 degC for 12 h with 20% H2 in N2 at 600 Pa, leaving a carbon-coated Si NT. For comparison, the sample of Si NT arrays/ CC was prepared without carbon deposition process. | train | 101016jjpowsour201601010 | [

Thermally induced formation of zinc oxide nanostructures with tailoring morphology during metal organic framework (MOF-5) carbonization process
Hydrochloric acid (36%) and N,N-dimethylformamide were purchased from Chempur (Poland). Zinc nitrate hexahydrate (Zn(NO3)2*6H2O), terephthalic acid (C6H4 (COOH)2) and triethylamine were bought from Sigma Aldrich.
The MOF-5 was prepared according to a previously reported procedure [26]. Briefly, 1.65 mmol of zinc nitrate hexahydrate, 0.89 mmol terephthalic acid and 3.25 mmol triethylamine (TEA) were dissolved in 2.34 mol N,N-dimethylformamide (DMF). The mixture was sonicated for 1 h. The solution obtained was transferred into an autoclave and stirred for 48 h at a temperature of 150 degC. The reaction vessel was then removed from the autoclave and allowed to cool to room temperature. Finally, the sample was vacuum-dried at 110 degC for about 2 h to remove the solvent.
Porous carbon was prepared by direct thermolysis of the previously obtained MOF-5. A ceramic boat containing the white MOF-5 powder was inserted into the centre of a tube furnace. The furnace was then heated from room temperature to the desired temperature (between 600 degC to 1000 degC), with a heating rate of 8 degC/min, The MOF-5 powder was maintained at this temperature for 2 h with an Ar flow of 100 ml/min. Cooling the MOF-5 back down to room temperature was followed by an investigation of the morphology of the samples obtained. | train | 101016jmatdes201608043 | [

Synthesis and characterization of nanocrystalline La2Mo2O9 fast oxide-ion conductor by an in-situ polymerization method
Nanocrystalline La2Mo2O9 powder was prepared by an in situ polymerization method using polyacrylates of La and Mo as the precursor compound. The polymeric precursor was made by solution polymerization of aqueous solution of acrylic acid in presence of La(NO3)3 and (NH4)6Mo7O24 with (NH4)S2O8 as the initiator. The typical experimental procedure is first to dissolve the stoichiometric amount of La(NO3)3*6H2O and (NH4)6Mo7O24*4H2O in triple distilled water and then the solution is pour into a acrylic acid solution (acrylic acid:H2O, 70:30 wt%) with constant stirring. To this a small amount of 5% (NH4)S2O8 solution was added as initiator to promote the polymerization. Under heating at ~80 degC, a well-distributed polyacrylates of La and Mo is formed. Afterward the resultant polyacrylates were dried at 120 degC for 1-2 h. The dried polymeric precursor was further heated to 520 degC for 5 h in air with a heating rate of 5 degC/min to eliminate the residual organic phase and get a nanocrystalline lanthanum molybdate powder. | train | 101016jmaterresbull200706005 | [

Stoichiometric amounts of LiOH*H2O and NH4VO3 (Li:V = 1:3, molar ratio) were mixed in deionized water with continuous magnetic stirring. The resultant little yellow solution was then transferred to a 100 mL Teflon lined autoclave. The autoclave was heated at 160 degC and maintained for 1 h under the microwave hydrothermal system (Sineo MDS-8, China). After the reaction, the autoclave was cooled to room temperature naturally and a colorless clear solution was obtained. This solution was dried in air at 80 degC for 10 h to prepare an orange gel. The gel was ground to powders and then calcined at 400 degC for 10 h in a muffle furnace under air atmosphere. Finally, the powders were cooled to room temperature naturally and ground again to obtain the final products, named as sample A. | train | 101016jmatlet201112019 | [

Performance improvement of lithium ion batteries using magnetite-graphene nanocomposite anode materials synthesized by a microwave-assisted method
Graphene oxide (GO) was prepared from graphite powder by the Staudenmaier method [24]. First, sulfuric acid and nitric acid were mixed well by stirring 15 min in an ice bath, and then graphite powder was dispersed into the solution. After 15 min, potassium chlorate was added into the system - very slowly to prevent strong reaction during the oxidation process. After reacting for 96 h, the mixture was diluted by de-ionized (DI) water and then filtered. The GO was next washed by hydrochloric acid to remove sulfate ions from the solution, which could be detected by adding BaCl2 in solution. After that, the mixture was repeatedly rinsed with DI water until its pH value became neutral. Finally, before the GO was ground into a powder in an agate mortar, the GO solution was filtered and dried in an oven at 80 degC overnight.
The GO powder was dispersed in DI water (1.5 mg/ml) by ultrasonication. The solution was mixed with Fe(NO3)3, urea, and ethylene glycol (EG) to form a homogeneous suspension. Next, the mixture was heated with different microwave powers - 200, 600, and 1000 W - under a reflux condition for 30 min. Before being dried overnight in the oven, the products were purified by washing repeatedly with DI water. Finally, Fe3O4/graphene nanocomposites were obtained by thermal reduction in an Ar atmosphere at 873 K for 4 h.

Synthesis, characterization, magnetic measurements and liquefied petroleum gas sensing properties of nanostructured cobalt ferrite and ferric oxide
All reagents such as ferric chloride, cobaltous acetate and ammonium hydroxide were of analytical grade and used without further purification. The stoichiometric amount of starting materials, such as cobaltous acetate and ferric chloride were taken in 1:1, 1:2, 1:3 and 1:4 M ratios, respectively, and dissolved into required amount of distilled water to form 1 M solution. First of all, we have taken cobaltous acetate and ferric chloride in 1:1 M ratios and dissolved into respective required amount of distilled water to form precursors. The above precursors were refluxed at 60 degC for 4 h to get homogeneous solution. After that both were mixed with each other. The obtained mixed solution was heated at 70-80 degC and magnetically stirred for 4 h. 10 ml of poly-ethylene glycol (PEG) was added to the mixed solution which acts as an encapsulating agent. The resulting solution was precipitated by ammonium hydroxide solution, which was added drop by drop to the above mixed solution and a black colored precipitate was obtained. The pH of the solution was constantly monitored as the NH4OH solution was added until it reached to 12. Then the mixture was mechanically stirred at room temperature for 6 h and the precipitate was washed several times with distilled water until the pH of the filtrate became 7. Here, ammonium hydroxide was used for smooth liberation of the hydroxide ions in place of strong alkali (potassium hydroxide and sodium hydroxide). Strong alkaline solutions are prone to result in the conversion of Fe3+ and Co2+ into CoFe2O4 immediately, usually leading to the formation of severely agglomerated nanoparticles with irregular shapes. Similar procedure was used for the synthesis of nanostructured ferric oxide.
Initially in aqueous solution, metal ions exist as Co ( H 2 O ) 6 2 + and Fe ( H 2 O ) 6 3 + . As pH was increased, the predominant species existing in solution became Co ( OH ) 6 2 - x and Fe ( OH ) y 3 - y , respectively. At the solubility minima, the predominant species in solution were Co(OH)2 and Fe(OH)3. Further, when the concentration of ammonia solution was increased, cobalt and iron became more soluble as Co ( OH ) 3 - and Fe ( OH ) 4 - species. The synthesis temperature was maintained at 70-80 degC for 4-5 h under vigorous magnetic stirring. The precipitate of CoFe2O4 was obtained through centrifugal settling for 15 min at 3000 rpm. The precipitate was dried overnight at 100 degC. The dried material was grinded into fine powder. The fine powder was then annealed at 450 degC inside a tubular furnace for 2 h with heating and cooling rate of 2 degC per minute. Sensing pellets of the synthesized powder were made by hydraulic press (MB instruments, Delhi) under a uniaxial pressure of 616 MPa. Hereafter, the cobalt ferrite pellets in 1:4, 1:3, 1:2 and 1:1 M ratios were named as P-1, P-2, P-3 and P-4, respectively. | train | 101016jmssp201402048 | [

Enhanced visible-light photocatalytic activity of strontium-doped zinc oxide nanoparticles
To begin the synthesis of Sr-doped ZnO-NPs, analytical grade zinc nitrate hexahydrate Zn(NO3)2*6H2O, strontium nitrate Sr(NO3)2, gelatin (type B from bovine skin), and distilled water were used as starting materials. All of the materials used were purchased from Sigma-Aldrich. The precursors were taken in the stoichiometric amounts of Zn1-xSrxO (x=0, 0.02, 0.04, and 0.06) to obtain final products. First, a gelatin solution was prepared by adding gelatin (3.65 g) to distilled water at 60 degC. The metal nitrates were dissolved separately in a minimal amount of distilled water at room temperature, and then these were added to the gelatin solution. After that, the compound solutions were stirred and heated at 80 degC until gels were obtained. The gels were calcined at 550 degC for 5 h, at a heating rate of 2 degC/min. | train | 101016jmssp201501013 | [

High-density iron nanoparticles encapsulated within nitrogen-doped carbon nanoshell as efficient oxygen electrocatalyst for zinc-air battery
Dicyandiamide and ammonium ferric citrate are used as pyrolysis precursors.
In a typical experiment, 8 g of dicyandiamide (C2H4N4, Alfa Aesar, denoted as DCDA) and 1 g of ammonium ferric citrate (C6H11FeNO7, J&K Chemical Ltd., denoted as AFC) were dissolved in 100 mL of de-ionized water. The solution was continuously stirred and dried at 80 degC. The obtained mixture was placed in a quartz tube of a horizontal furnace. The pyrolysis of the mixture was performed in Ar atmosphere at a flow rate of 50 mL min-1. The furnace was heated to the target temperature at a rate of 10 degC min-1 and kept at the target temperature for 2 h, then cooled to room temperature. Then the samples were leached in 0.5 M HClO4 solution at 80 degC for 8 h to remove unstable iron species, and washed thoroughly with de-ionized water. Finally, the samples were dried at 60 degC in an oven. For highlighting the role of iron precursor, ferric chloride was used instead of AFC, and the mixture of DCDA and ferric chloride was pyrolyzed at 700 degC, followed by acid-leaching and washing, which is denoted as D-FC-700. The weight ratio of DCDA to iron was kept identical in the DCDA-AFC and DCDA-FeCl3 mixtures. | train | 101016jnanoen201502025 | [

In a typical synthesis, 3 mL of titanium tetrachloride (TiCl4) was added to 84 mL of isopropanol. Then the solution was still magnetically stirred for 30 min. Subsequently, the precursor solution was then transferred into a 150 mL Teflon-lined autoclave and kept at 200 degC for 24 h. After this hydrothermal reaction, the reaction was naturally cooled to room temperature. The recovered white precipitate was washed thoroughly with ethanol and dried at 60 degC for 12 h.

ZnO nanowire/reduced graphene oxide nanocomposites for significantly enhanced photocatalytic degradation of Rhodamine 6G
ZnO NWs were prepared by a modified carbothermal reduction method in our previous work [23]. The mixture of ZnO powder and graphite (500 mesh) with a weight ratio of 1:0.8 was placed in the middle of the furnace. The furnace was heated to 1150 degC and purged with mixed gas of air (0.1 L/min) and N2 (4.5 L/min) as reactive and carrier gas. After about 5 min, white snowflake-like product was carried out by the carrier gas and collected by a 5000 mL flask at the downstream of the furnace.
GO was prepared by a modified Hummers' method. In a typical experiment, 0.5 g graphite oxide was ultrasonicated in deionized water with 0.1 g PVP to form GO solution. Then 0.5 g ZnO NWs were added into GO solution. After that, the mixture was stirred at room temperature for 2 h, followed by centrifuging and washing with deionized water to remove impurities. Finally, the nanocomposites were desiccated at 50 degC overnight and further thermally reduced at 300 degC.

Synthesis and gas permeability of highly elastic poly(dimethylsiloxane)/graphene oxide composite elastomers using telechelic polymers
First, a known amount of telechelic PDMS (for 1 wt % GO composites, 990 mg) was dissolved in THF (6 ml) while stirring to ensure complete dissolution of the polymers. Then, dried GO (10 mg) was suspended in the solution with vigorous stirring, and a homogeneous dispersion of GO in this solution was promoted by sonication using a 400 W probe sonicator (Branson Digital Sonifier 450) with 10% amplitude for 10 min (24 kJ) in an ice bath. It is noteworthy to point out that, although THF is not a good solvent for GOs, amine terminated telechelic PDMS can effectively act as a surfactant to assist in dispersing GOs homogeneously in THF through hydrogen bonding between amine ends and oxygen containing groups on GO surfaces. A good dispersion after sonication was confirmed by examining the residual liquid film in the vial while rolling the vial containing the solution and after pouring the majority of the solution into a PTFE dish for solution casting. In either case, the liquid film in the vial was essentially transparent (although brownish-black from the GO content) for all solution concentrations and no aggregates could be identified with the naked eye. This solution was immediately poured into a Teflon dish and covered in order to slowly evaporate the solvent thereby solution casting a film at room temperature. Solvent was evaporated for at least 2 days and then the sample was vacuum dried at room temperature for an additional day to make a homogenous PDMS/GO uncrosslinked liquid sol. In order to form a crosslinked elastomer, the sol precursor was heated to 160 degC in a vacuum oven for 24 h and cooled slowly to room temperature before use. | train | 101016jpolymer201604016 | [

Synthesis, characterization of mesoporous silica powders and application to antibiotic remotion from aqueous solution. Effect of supported Fe-oxide on the SiO2 adsorption properties
Cetyltrimethylammonium p-toluene sulfonate or tosylate (CTAT, MW = 455.7 gmol- 1), Pluronic F68 and tetraethyl orthosilicate (TEOS, 99%) were purchased from Aldrich. Iron(III) nitrate nonahydrate, potassium hydroxide, potassium chloride, potassium nitrate, nitric acid, hydrochloric acid, sodium acetate, acetic acid, sodium carbonate, sodium hydrogen carbonate, disodium phosphate anhydrous, and monosodium phosphate anhydrous were obtained from Anedra.
All chemicals were of analytical grade and used as received. Doubly distilled water was used for the preparation of solutions.
Mesoporous silica was prepared using a procedure similar to that described in an earlier work [12]. Briefly, 11.6 mL of TEOS were mixed with 2 mL of water and stirred in an autoclave flask for 10 min at 500 rpm. At the same time, 38 mL of CTAT-Pluronic F68 mixed solution were prepared with a 0.75:0.25 M ratio by adding the desired amount of surfactants to water. This mixture was stirred in a conical flask at 35 degC to form a transparent template solution and then it was left at room temperature. To obtain the mesoporous material, 20 mL of a 1.43 M HCl solution were added drop by drop to the TEOS solution under stirring and 2 min later the surfactant solution was incorporated. The resulting gel, whose composition was 1 TEOS:0.53 HCl:0.011 CTAT:0.0037 F68, was stirred for 5 min and then left for 48 h in an autoclave at 100 degC. After this, the gel was filtered and washed with distilled water and dried at room temperature. Finally, it was calcined in an air flux by increasing the temperature from room temperature to 540 degC with a heating rate of 2degCmin- 1, and holding for 7 h at 540 degC.
Fe-SiO2 was synthesized by a simple batch equilibrium adsorption method. In a beaker, 2 g of calcined SiO2 were mixed with 40 mL of a 0.13 M Fe(NO3)3 solution and stirred for 1 h at 600 rpm. Then, the solid was filtered and washed with water and dried at room temperature. Finally, it was calcined in an air flux for 2 h at 540 degC. The iron content on the silica support was 10.3 mgg- 1 (1.03 wt.%), which was measured by UV-VIS spectroscopy using the thiocyanate colorimetric method [23] after extracting the Fe(III) ions from the solid with concentrated HNO3[24]. | train | 101016jpowtec201311008 | [

A novel chemical process of Bi2Te2.7Se0.3 nanocompound for effective adjustment in transport properties resulting in remarkable n-type thermoelectric performance
Bismuth shots (Bi, Kojundo Chemical, 99.99%, 2-5 mm) dissolve in diluted nitric acid (2.5 M HNO3(aq)) to subsequently form a transparent solution, which showed signs of bismuth oxidation to generate bismuth ions (Bi3 +) and nitrate (NO3-). Tellurium powders (Te, Kojundo Chemical, 99.99%, 45 μm) do not dissolve in HNO3 but they turn to white precipitates, indicative of tellurium oxidation to form tellurous acid (H2TeO3), which is one of the most stable Te oxoacids. When exposing the reactant elements to HNO3 simultaneously, we observed an entirely different phenomenon; the Te powders gradually dissolved with the Bi shots, resulting in a transparent solution. We assumed that the Te was oxidized by NO3- from the Bi oxidation instead of HNO3, and thus tellurite (TeO32 -) might form rather than H2TeO3 (Eq. (1)) -- a small portion of Te was replaced with selenium powders (Se, Kojundo Chemical, 99.9%, 75 μm) to prepare a ternary compound. | train | 101016jscriptamat201603010 | [

The sulfide (1 mmol) was added to a solution of 30% H2O2 (1.2 equiv, 0.5 g) and boric acid (0.1 mmol, 0.006 g), and the mixture was stirred at room temperature for the time specified in Table 2. The progress was monitored by TLC or GC. After completion of the reaction, the product was extracted with CH2Cl2 (3 x 10 mL) and the combined organics was washed with brine (15 mL) and dried over anhydrous Na2SO4. The solvent was removed under reduced pressure to give the corresponding pure sulfoxide in most cases. Further purification was achieved by short-column chromatography on silica gel with EtOAc/n-hexane (1/10) as eluent. All the products are known and were characterized by IR, 1H NMR, and by melting point comparisons with those of authentic samples. 8, 23, 24, 25 and 26

The (TiVCrZrHf)N coatings were deposited on p-Si (100) wafers by a reactive RF magnetron sputtering system using equimolar TiVCrZrHf targets (75 mm in diameter). Before deposition, the Si substrates were cleaned and rinsed with ethanol and distilled water in an ultrasonic bath. Then, 1.4 μm-thick (TiVCrZrHf)N coatings were deposited at a plasma power of 350 W and a substrate bias of - 100 V in an Ar + N2 mixed atmosphere under a working pressure of 6.67 x 10- 1 Pa at 450 degC. The flow rates of Ar and N2 were maintained at 100 and 4 sccm, respectively. To determine the oxidation resistance of the as-deposited (TiVCrZrHf)N coatings, they were annealed at different temperatures (300-700 degC) for 2 h in air using a furnace. | train | 101016jtsf201212064 | [

Vertical MgZnO Schottky ultraviolet photodetector with Al doped MgZnO transparent electrode
Al thin film was grown on a commercial c-plane sapphire substrate by using radio frequency (RF) magnetron sputtering technique. A ceramic target with 45 wt.% MgO, 54.81 wt.% ZnO and 0.19 wt.% Al2O3 was used. The ceramic target was made by the Northeast Normal University. The sputtering rate is about 5 nm/min and the chamber pressure was maintained at 1.8 Pa. Oxygen with 20 sccm flow rate and argon with 40 sccm flow rate were used as the sputtering gas. The thickness of the as-grown film was 300 nm. Then the as-grown MgZnO:Al films were vacuum annealed for 1 h in different temperatures to reduce the resistivity of the MgZnO:Al thin film, in order to meet the requirement of the device. | train | 101016jtsf201309083 | [

Membranes of MnO Beading in Carbon Nanofibers as Flexible Anodes for High-Performance Lithium-Ion Batteries
Polyacrylonitrile (PAN, Mw = 80000) was made in laboratory52. Potassium permanganate (KMnO4, AR), sulfuric acid (H2SO4, AR) and N,N-dimethylformamide (DMF, AR) were purchased from Shanghai Lingfeng Chemical Reagent Co., Ltd. Manganese sulfate monohydrate (MnSO4*H2O, AR) was purchased from Sinopharm Chemical Reagent Co., Ltd. All these reagents were used without further purification.
MnO2 NWs were synthesized by a hydrothermal method. Briefly, aqueous solutions of MnSO4*H2O (1 mmol) and KMnO4, (1.5 mmol) (Mn(II)/Mn(VII) = 3:2) were mixed with vigorously stirring. The PH value of the mixture was adjusted ~2 with 5 M H2SO4 aqueous solution. Then the solution was transferred to an autoclave and reacted in oven at 140 degC for 12 h. After cooling down, the product was collected by filtration and washed repeated with distilled water and absolute ethanol. Then the MnO2 NWs powder was obtained.
The obtained MnO2 NWs powder was washed three times with DMF, centrifuged and then added into a certain-mass 8 wt% PAN/DMF solution as an electrospinning solution. Intensive stirring was conducted for 12 h in order to get a homogeneously distributed solution. Then the blended solution was electrospun into MnP membranes, with a controlled syringe pump of 25 μL min-1 and an applied voltage of 20 kV with a distance of 20 cm between the electrospinning jet and the collector. The adding amounts of MnO2 NWs based on PAN were 10 wt%, 20 wt% and 30 wt% for MnP-1, MnP-2 and MnP-3, respectively. | train | 101038srep14146 | [

Real-time oxide evolution of copper protected by graphene and boron nitride barriers
The graphene samples were grown using a commercial Annealsys AS-ONE cold-wall chemical vapour deposition (CVD) reactor on 25 μm-thick electropolished copper foils. First, the Cu foils were annealed in argon at 1035 degC in atmospheric pressure for 10 minutes, then graphene was synthesised at the same temperature at a pressure of 25 mbar using a mixture of 900sccm Ar, 60sccm H2 and 2sccm CH4 for 15 minutes. hBN coatings were grown using a quartz tube furnace on the same batch of electropolished copper foils used for growing graphene. The growth was done at 900 degC at a total pressure of 60 mbar for 15 minutes with a mixture of 300sccm Ar, 15sccm H2 and 3sccm of borazine (B3H6N3, from Fluorochem). | train | 101038srep39770 | [

Role of oxygen functional groups in reduced graphene oxide for lubrication
The sample was prepared by Hummer's method44,45. Graphite flakes (10 g) and NaNO3 (10 g) were mixed in 500 mL of H2SO4 (98%) at 5 degC with continuous stirring for 2 h, and KMnO4 (30 g) was gradually added to the suspension at a controlled reaction temperature lower than 15 degC. The ice bath was then removed, and the mixture was stirred at 35 degC until it became pasty brownish; stirring continued for two days, after which the mixture was diluted with a slow addition of 300 ml of water. The reaction temperature was rapidly increased to 98 degC, and the color changed to dark brown. This solution was further diluted by adding an additional 400 ml of water and stirring continuously. The solution was finally treated with 150 ml of H2O2 to terminate the reaction, indicated by the appearance of a yellow color. For purification, the mixture was washed by rinsing and centrifugation with 10% HCl and then with deionized water (DI) several times. After filtration and drying under a vacuum at room temperature, the GO1 was obtained as powder. Reduction was performed to reduce the functional group density, towards decreasing the inter-plane spacing and the flake dimensions and improving the friction properties. Reduction was done via treating 100 mg of GO1 in 30 mL of water with 3 mL of hydrazine and refluxing at 95 degC for 24 h, followed by filtering, washing and drying at 60 degC under vacuum to obtain the rGO1 powder.
Graphite flakes (10 g) and NaNO3 (10 g) were mixed in 600 mL of H2SO4 (98%) at 5 degC with continuous stirring for 6 h, and KMnO4 (60 g) was gradually added to the suspension while maintaining the temperature at 15 degC. The mixture was diluted with a slow addition of 400 mL of water and with stirring maintained for 2 h. The ice bath was then removed, and the mixture was stirred at 35 degC for 2 h and then refluxed at 98 degC for 30 min. The solution was finally treated with 200 ml of H2O2 and the color changed to bright yellow. The resulting mixture was washed by centrifugation with 10% HCl and then with DI water several times until it became gel-like. After centrifugation, the gel was vacuum dried at 80 degC for 8 h to obtain the GO2 powder. Reduction was performed similarly to rGO1. | train | 101038srep45030 | [

Hydrothermal chemistry of vanadium oxides with aromatic di- and tri-phosphonates in the presence of secondary metal copper(II) cationic complex subunits
All chemicals were used as obtained without further purification: vanadium(V) oxide, copper(II) acetate hydrate, copper(II) nitrate hydrate, 2,2'-dipyridine, 2,2'-dipyridylamine, 1,10-phenanthroline, 2,2':6,2''-terpyridine, and hydrofluoric acid (48 to 51%) were purchased from Aldrich. The phosphonate ligands 1,4-phenyldiphosphonic acid, 1,3-phenyldiphosphonic acid, and 1,3,5-phenyltriphosphonic acid were prepared according to the literature method.57 The copper mononucleating ligand 2-pyridylcarboxylic acid was prepared by refluxing 2-cyanopyridine in concentrated HCl overnight, and subsequent removal of excess liquid. All syntheses were carried out in 23mL poly(tetrafluoroethylene) lined stainless steel containers under autogenous pressure. The reactants were stirred briefly and initial pH was measured before heating. Water was distilled above 3.0 M Ω in-house using a Barnstead Model 525 Biopure Distilled Water Center. The reactions initial and final pH was measured using Hydrion pH sticks.

Synthesis, acid properties and catalysis by niobium oxide nanostructured materials
Dichloromethane and acetonitrile were purified with a LC Technology Solutions Inc. SPBT-1 Bench-Top Solvent Purification System. Compound 1 was synthesized according to literature procedures.9 NbCl5 and Nb(OEt)5 used in the preparation of T-I and T-II were purchased from Sigma-Aldrich and used as received. Commercial Nb2O5 (Puratronic(r), 99.9985%) was purchased from Alfa Aesar and used as received. Pluronic (P123) and dodecylamine 98% were used as structure-directing agents and were purchased from Sigma-Aldrich. Milli-Q water (resistivity 18.2 MΩ cm-1 at 25 degC; 0.22 μm filter) was used in all preparations and reactions requiring aqueous conditions.
Synthesis of the Nb2O5 materials discussed within this contribution have been adapted from previously reported procedures. The methods used are briefly described in the following paragraphs:
5 g of NbCl5 (18.5 mmol) were dissolved in 99% ethanol (10 mL) under constant stirring. To this solution NH4OH (1 M) was slowly added to the aforementioned solution until a white precipitate was observed. The precipitate was then separated from the solution by centrifugation (3000 rpm), washed four times using Milli-Q water and dried at 120 degC for 24 hours.
5 g of NbCl5 (18.5 mmol) were dissolved in 200 mL Milli-Q water. Immediately after addition, the yellow powder became white. After stirring for 3 h at room temperature, the white precipitate was centrifuged (3000 rpm) and washed four times with Milli-Q water until the filtrate was at neutral pH. The obtained solid was dried at 120 degC for 24 hours.
1.5 g of P-123 were dispersed in 11 mL of Milli-Q water and 45 mL of HCl (2 M) at 40 degC. 5 g of Nb(OEt)5 (15.7 mmol) was added to solution under stirring. The resulting mixture was kept at 40 degC for 24 hours and then precipitated in a Teflon-lined autoclave at 100 degC for 48 hours. The obtained solid was filtered, washed with Milli-Q water and dried in air at room temperature. Excess surfactant was removed by Soxhlet extraction first by washing with 1% HCl in 95% EtOH (300 mL) and then with 95% EtOH only (120 mL). The final, template-free mesoporous Nb2O5*nH2O was dried in the oven at 120 degC for 18 hours. A mixture of Nb(OEt)5 (3.25 g, 10.3 mmol) and dodecylamine (0.57 g, 3.1 mmol) was heated until a homogeneous solution was obtained. Subsequent addition of 65.4 mL of Milli-Q water with manual stirring resulted in the formation of a gel-like precipitate. Further addition of 27.6 μL (0.3 mmol) concentrated HCl afforded a white precipitate. The reaction mixture was allowed to stand overnight, sealed and heated at 40 degC for 30 hours, 60-65 degC for 66 hours, 80 degC for 48 hours, and 95-100 degC for 5 days. The solid was then cooled down, collected by filtration and dried at 95-100 degC for 2 hours, 120 degC for 48 hours, and 140 degC for 48 hours. The white solid was then washed four times to remove the presence of excess surfactant. Each washing cycle was conducted for 24 hours under vigorous stirring followed by Buchner filtration. 645 mg (3.4 mmol) of p-toluenesulfonic acid in 13 mL of ether were added to 100 mL of MeOH for the first wash. For the second wash, 65 mg (0.3 mmol) of p-toluenesulfonic acid in 3 mL of ether were added to 100 mL of MeOH. Third and fourth washings were done using MeOH (100 mL) only. The final, template-free mesoporous Nb2O5*nH2O was dried into the oven at 120 degC for 24 hours. | train | 101039c4cy00238e | [
