Electrochemical Behavior of the Li+/Li Couple and Stability of Lithium Deposits in Tri‐1‐Butylmethylammonium Bis((Trifluoromethyl)Sulfonyl)Imide Room Temperature Ionic Liquid
Authors: Chen Po‐Yu 
Published: May 2015

AbstractThe electrochemical behavior of the Li+/Li couple was studied at polycrystalline tungsten, platinum, copper and aluminum electrodes in tri‐1‐butylmethylammonium bis((trifluoromethyl)sulfonyl)imide ionic liquid mixed with a little propylene carbonate at 30 °C. Lithium cations were introduced into the ionic liquid by dissolution of lithium bis((trifluoromethyl)sulfonyl)imide which is highly soluble in ionic liquid. Propylene carbonate was used to reduce the viscosity of this ionic liquid in order to enhance the mass transfer and to additionally improve the stability of lithium deposits. At the tungsten and copper electrodes, the cyclic voltammetric behavior of a Li+/Li couple is a quasi‐reversible reaction. At the platinum electrode, the behavior becomes very complicated because of the alloy formation. Coulombic efficiency was used to evaluate the stability of lithium deposits at each electrode. The aluminum electrode showed the best efficiency due to the formation of Li‐Al alloy. However, lowest efficiency was obtained at the platinum electrode because of the low redox reversibility of the lithium in the Li‐Pt alloy. The diffusion coefficient of lithium cation in this solution was 1.0 ± 0.1 × 10−;7 cm2 s−;1 as determined by chronopotentiometry. The best coulombic efficiency obtained at the Al electrode is 97% but dropped to about 90% after 12 hours. The self‐discharge current of the lithium deposits at the Al electrode was 0.4 μA/cm2 during the experimental period.

Published: May 2015

AbstractThis paper demonstrates the spectral analysis of some distillates obtained from asphalt cracking in the presence of a conventional expensive catalyst, i.e., HZSM‐5, and local cheap and readily available clay, i.e., UTIMAC. Each distillate was fractionated into pentane soluble (PI) and pentane insoluble (PI) fractions based on solubility in n, pentane. Both PS and PI obtained in the case of HZSM‐5 and UTIMAC were analyzed by 1H‐NMR spectrophotometry using CDCl3 as dissolving solvent and tetramethylsilane (TMS) as internal standard. It is evident from the profiles that both catalysts caused the generation of some peaks ascribed to methylene and methene configurations in the aliphatic region. Bands corresponding to aromatic configurations were also generated. The results indicate that the cheap local catalyst used has comparable suitability with the conventional expensive catalyst in terms of asphalt cracking.

Published: May 2015

AbstractPyrolysis has the potential of transforming used tyres into useful recyclable products. Pyrolytic carbon black is one of the most important products of tyre pyrolysis. Waste tyres were pyrolysed at 450 °C in a batch reactor under atmospheric pressure. The recovered pyrolytic carbon black residues were studied to investigate their characteristics for use as a possible adsorbent. EDX elemental analysis and surface area determinations were used to investigate the distinctive features of pyrolytic carbon black. Due to various inorganic additives of the original tyre that contaminated the carbon black obtained, it was treated with acid for demineralization. The demineralized carbon black was activated at 900 °C in a furnace. It was observed that acid treatment and activation increased the surface areas and decreased the concentration of contaminants. Furthermore, adsorption characteristics of methylene blue on acid‐treated and activated carbon black (prepared via acid treatment) were compared with those of commercial activated carbon in liquid phase adsorption. It was found that adsorption capacity of methylene blue on acid‐treated activated carbon black was greater.

AbstractOxidative cyclization of the sugar hydrazones (3a‐f) derived from {7H‐1,2,4‐triazolo[1,5‐d]tetrazol‐6‐ylsulfanyl}acetic acid hydrazide (1) and aldopentoses 2a‐c or aldohexoses 2d‐f with bromine in acetic acid in the presence of anhydrous sodium acetate, followed by acetylation with acetic anhydride gave the corresponding 2‐(per‐O‐acetyl‐alditol‐l‐yl)‐5‐methylthio{7H‐1,2,4‐triazolo[1,5‐d]tetrazol‐6‐yl}‐1,3,4‐oxadiazoles (5a‐f). Condensative cyclization of the sugar hydrazones (3a‐f) by heating with acetic anhydride gave the corresponding 3‐acetyl‐2‐(per‐O‐acetyl‐alditol‐1‐yl)‐2,3‐dihydro‐5‐methylthio{7‐acetyl‐1,2,4‐triazolo[1,5‐d]tetrazol‐6‐yl}‐1,3,4‐oxadiazoles (11a‐f). De‐O‐acetylation of the acyclo C‐nucleoside peracetates (5 and 11) with methanolic ammonia afforded the hydrazono lactones (7) and the acyclo C‐nucleosides (12), respectively. The structures of new oxadiazole derivatives were confirmed by analytical and spectral data.

Published: May 2015

AbstractThe biological activity relationship of 36 flavonoid compounds was investigated using theoretical methods including quantitative structure activity relationships (QSAR) and quantum chemistry calculation. The results suggested that the 5 and/or 8 positions of the substituents of the hydroxyl group in the A ring and the 3′ and 4′ positions of substituents of the hydroxyl group in the B ring play an important role in flavonoid biological activity. This is probably due to the formation of an intra‐molecular hydrogen bond. In addition, the electronic energy, electrostatic energy and bond energy may have an effect on the biological activity of flavonoids. Also, our analysis has shown that the presence of the 1,4 and 1,2‐hydroquinone in the A ring and/or the Bring of flavonoids and the contribution of electronic energy, electrostatic energy and bond energy required consideration in the generation of the QSAR model and that the potential compounds will be predicted out of 36 flavonoids.
Electrocatalytic Activity of Methanol Oxidation at a Boron‐doped Diamond Electrode in Alkaline Solution

Published: May 2015

AbstractThe electrocatalytic activity of methanol oxidation at a boron‐doped diamond (BDD) electrode in alkaline solution is investigated by voltammetry and electrochemical impedance spectroscopy. Methanol oxidation in this work involves the generation of OH radicals. The intermediate, as formaldehyde, adsorbed at the BDD electrode surface is subsequently oxidized to formic acid or CO2 by OH radicals. Additionally, the reaction is influenced by the ratio of methanol and OH− concentration in the solution and is enhanced with the increased OH− concentration. Methanol adsorption at the BDD electrode surface is an important factor and difficult in this work. However, formaldehyde adsorption is more difficult than methanol. Methanol oxidation in this investigation is dominated by organic adsorption at a lower potential range. With the increased potential, it is gradually dominated by the generation of OH radicals.

Abstractγ‐(D,L)‐Polyglutamic acid [γ‐(D,L)‐PGA, or γ‐PGA] produced by Bacillus subtilis (natto) both on laboratory and pilot scale fermenter systems has been characterized. γ‐PGA in its free acid form (H+) is insoluble in water. The salt forms of K+, Na+, NH4+, Ca2+, and Mg2+ of γ‐polyglutamates are fully soluble in water. The structural characteristics of the salts of γ‐Polyglutamates (Na+, K+, NH4+, Ca2+, and Mg2+) were determined with 1H‐ and 13C‐NMR spectroscopy and FT‐IR spectroscopy. The thermal properties were determined with thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The typical physical and chemical properties including pH‐titration curve, concentration‐dependent viscosity temperature‐dependent viscosity, and heavy metal binding properties with Pb2+, Cd2+, and Cu2+ were also determined. The biological functionalities were partially characterized with in vivo feeding studies with broilers and egg‐layers, and activation of GTF (Glucose tolerance factor) activity with rat 3T3‐L1 cell culture studies. γ‐(D,L)‐Polyglutamic acid [γ‐(D,L)‐PGA] appears to have five different conformations depending on the environmental conditions. They are the α‐helix, β‐sheet, helix‐to‐random coil transition, random‐coil and enveloped aggregate. The conformational states, hydrogen bonding and polyanionic nature make γ‐PGA a versatile multi‐functional biopolymer possessing many useful biological functionalities.

AbstractThe carboxylic acid 4‐hydroxybenzoic acid, bonded directly with (R)‐2‐octanol, is the core molecule of chiral liquid crystal (R)‐MHPOBC. This acid was substituted either by 6‐hydroxynicotinic or by 4‐hydroxyphenylacetic acid. Such a structural variation induced a remarkable influence on the liquid crystal properties of (R)‐MHPOBC. The series of compounds 1˜4 containing 6‐hydroxynicotinic acid moiety tend to exhibit a chiral smectic C (SmC*) phase, while the series of compounds 5˜8 containing 4‐hydroxyphenylacetic acid moiety tend to possess a chiral nematic (N*) phase.

Published: May 2015

AbstractThe synthesis, characterization, and mesomorphic properties of a series of homologue compounds 1 derived from salicylaldehydes are reported. These compounds were characterized by 1H, 13C‐NMR spectroscopy and elemental analysis. The phase behavior of these mesogenic compounds was characterized and studied by differential scanning calorimeter (DSC) and polarization optical microscope. All compounds 1 were found to be mesogenic, and the mesophases were dependent of the carbon length of the spacer group. The results indicated that all compounds with an even‐carbon spacer (m = 2, 4, 6, 8) exhibited smectic C phases; however, all other compounds with an odd‐spacer (m = 3, 5, 7) formed banana phases. The difference in phase behavior was attributed to the dependence of the molecular shape and/or geometry on the parity of the central spacer when considered in the all‐trans‐conformation. The formation of the mesophases was related to the optimized conformation of the compounds. The most stable optimized geometry was also simulated by the semi‐empirical Spartan ′04 version 1.0.0/AM1 method.

Published: May 2015

Abstract4,4′‐Azo‐bis(triarylamine) derivatives with electron‐donating groups have been synthesized. Their spectral and electrochemical characteristics have been investigated. Their first and second oxidations exhibited different degrees of overlapping, depending on the electron‐donating groups at the para‐position of the phenyl rings. The stability of the oxidation products was monitored with UV/VIS/NIR spectro‐electrochemical methods. The derivatives have much stronger IV‐CT bands in the near‐IR range. The spectral change reveals the number of electron transfer in the stepwise oxidation and the stability of the products.

AbstractDensity functional theory (DFT) calculations are made and least squares calibration performed for various halohydrocabons, which were 27 straight‐chain alkyl halides, 20 branch‐chain alkyl halides and 19 aromatic halides, to determine their enthalpies of formation (ΔHf). The mean absolute error (M. |A.E.|) in ΔHf across 66 molecular computations was only 7.8 kJ/mol (1.9 kcal/mol). Grouping the molecules by their structural characteristics improved M. |A.E.| of ΔHf by 0.2–2.2 kJ/mol over that obtained using corresponding modified data for the same 66 unclassified molecules.

AbstractReactions of formylferrocene and 1,2‐di‐(o‐aminophenoxy)ethane yield the novel bis(ferrocenyl) receptor (FcL). This compound has been characterized by IR, 1H NMR and elemental analysis. In addition, the electrochemical behavior of FcL was investigated in detail in 0.1 M tetra‐n‐butylammonium perchlorate (TBAP) + CH3CN by cyclic voltammetry (CV) and chronoamperometry. Its co‐ordination properties with metal ions in acetonitrile were also studied. The FcL shows a two‐wave behavior for H+, Cu2+, Zn2+ and Ni2+, but was unresponsive to Mg2+ and Ca2+. The maximum oxidation peak shift of about 250 mV was found for FcL in the presence of Cu2+, Zn2+ or Ni2+.

A Theoretical Study of 1‐D and 2‐D Helium Lattices
Authors: Sabzyan Hassan , Zanjanchi Farzaneh 
Published: May 2015

AbstractOne‐ and two‐dimensional (1‐D and 2‐D) helium lattices have been studied using ab initio RHF/6–31G** computations. Structural, physical and thermochemical properties have been calculated and analyzed for the 1‐D and 2‐D HeN lattices respectively up to N = 50 and N = 36. Asymptotic properties of the 1‐D HeN lattices are obtained by extrapolating N‐dependence properties to large values of N. Analysis of the results show that the bulk per‐atom interaction (binding) energies increase while the optimized interatomic distances (bond lengths) slightly decrease with the increase in size of the 1‐D HeN lattices and both reach their asymptotic values of 0.352 cm−1 and 3.18775 Å, respectively. Between the square and hexagonal (packed) structures of the 2‐D HeN lattices, the latter is more favored. Extrapolated values of the calculated properties, including lattice parameter, binding and zero point energies, heat capacity, and entropy have also been calculated for both 1‐D and 2‐D HeN lattices. The surface densities for monolayer films of helium atoms with square and hexagonal configurations have been calculated to be respectively 9.84 × 1018 and 1.04 × 1019 helium atoms/cm2 which are comparable to the experimental value of 2.4 × 1019 helium atom/m2 well within the typical large and directional error bars of the experiments. Surface effects have been investigated by comparing the packed HeN2‐D lattices with the same value of N but with different geometries (arrangements). This comparison showed that the HeN lattices prefer arrangements with the smallest surface area.
