Location of ethanol in sodium dodecyl sulfate aggregates
Authors: Tian‐Qing Liu , Wd‐Li Yu , Rong Guo 
Published: September 2010

AbstractThe hexagonal liquid crystalline phase of SDS (Sodium dodecyl sulfate)/H2O system changes into lamellar liquid crystal and the effective length of surfactant molecule d0/2 in the lamellar liquid crystal decreases with the addition of ethanol. The micellar aggregation number N of SDS decreases and the micellar diffusion coefficient increases with the added ethanol. Under a constant concentration of SDS, the molecule number ratio of ethanol to SDS in the micelle increases with the concentration of ethanol and even exceeds 10 when ethanol concentration is 1. 085 mol/L. All these results show that ethanol, even though a short chain alcohol and soluble in water, can partly exist in the interphase of the amphiphilic aggregates showing some properties of co‐surfactant.
Retention model of protein for mixed‐mode interaction mechanism in ion exchange and hydrophobic interaction chromatography
Authors: Yin‐Mao Wei , Quan‐Zhou Luo , Tong Liu , Xin‐Du Geng 
Published: September 2010

AbstractA unified retention equation of proteins was proved to be valid for a mixed‐mode interaction mechanism in ion exchange chromatography (IEC) and hydrophobic interaction chromatography (HIC). The reason to form a “U” shape retention curve of proteins in both HIC and IEC was explained and the concentration range of the strongest elution ability for the mobile phase was determined with this equation. The parameters in this equation could be used to characterize the difference for either HIC or IEC adsorbents and tbe changes in tbe molecular conformation of proteins. With the parameters in this equation, the contributions of salt and water in tbe mobile phase to the protein retention in HIC and IEC were discussed, respectively. In addition, the comparison between the unified equation and Melander's three‐parameter equation for mixed‐mode interaction chromatography was also investigated and better results were obtained in former equation.

Published: September 2010

AbstractWe first make use of aminolysis of calix[4]arene esters to synthesize calix[4]arene amides. When the two ethyl esters of the calix[4]arene esters are aminolysized, the 1, 3‐amide derivative is formed selectively. The crystal structures of the calix‐[4] arene with two butyl amide (3b) and four butyl amide moieties (4b) were determined. The intermolecular hydrogen bonds make 4b form two‐dimensional net work insolid state. The 1H NMR spectra prove mat 3b is of a pinched cone conformation, while 4b and tetraheptylamide‐calix[4]arene (6b) take fast interconversion between two C2r isomers in solution and appear an apparent cone conformation at room temperature. As decreasing temperature, the interconversion rate decreases gradually and, finally, the interconversion process is frozen at Tc = −10°C, which makes both conformations of 4b and 6b the pinched cone structures. The hydrogen bond improves the interconversion barrier, and the large different values of the potential barrier between 6b and 4b (or 6b) may be of forming different hydrogen bonds.

Authors: Chun‐Hai Fan , Gen‐Xi Li , De‐Xu Zhu , Jian‐Qin Zhu 
Published: September 2010

AbstractAn imidazole modified silver electrode is prepared by immersing the substrate silver electrode in a 2% imidazole solution of ethanol at 50°C for 10 min. The modified electrode is men swept in a cytochrome c solution and the modified layer takes off because the modified electrode is very unstable. Although the amount of the silver‐imidazole complex is very small compared with the amount of cytochrome c in the protein solution, it greatly facilitates redo reactions involving the biomacromolecules.

Authors: Ji‐Liang Shi , Hu‐Nan Yi , Jia‐Yi Xu , W‐Kui Jiang 
Published: September 2010

AbstractAggregation of some nitrogen‐containing heterocyclic compounds have been investigated by means of fluorescence spectroscopy in aqueous or aquiorgano binary mixtures of different Φ values for the first time. The aggregators studied are N‐butylcarbazole (CBZ‐4), N‐octylcarbazole (CBZ‐8), N‐dodecylcarbazole (CBZ‐12), and N‐hexadecylcarbazole (CBZ‐16). Their aggregating tendencies have been evaluated by measuring their critical aggregate concentration values (CAgC's). Our results indicate that the N‐alkylcarbazoles, just like the anthracene derivatives with different chain‐lengths, can also be used as fluorescence probes for evaluating aggregating tendencies or CAgC values.

Published: September 2010

AbstractA trinuclear linear Mo‐Fe‐Mo dialkyldithiocarbamate complex [Et4N] {[Me2dtcMoO(μ‐S)2]2Fe} has been obtained and structurally characterized, which contains two Me2dtcMoO(μ‐S)2 units coordinated to a central tetrahedral Fe atom. A comparison of the structural parameters indicates the metal oxidation states of 2Mo(v) + Fe(III). The 1H NMR shows chemical shifts of Me2dtc ligands at δ 10.14 and δ 9.40 with the intensity ratio of 1:1. Tbe cyclic voltammogram displays a reversible couple at ‐1.41 V/ ‐1.36 V responsible for 1‐/2‐anions of tbe complex and an irreversible oxidation at 0.5 V, which seems to show the apparent lack of stability for its neutral species (Me2dtcMoOS2)2Fe.

Published: September 2010

AbstractThe interface diffusion and chemical reaction between a PZT (PbZrxTi1‐xO3) layer and a Si(111) substrate during the annealing treatment in air have been studied by using XPS (X‐Ray Photoelectron Spectroscopy) and AES (Auger Electron Spectroscopy). The results indicate that the Ti element in the PZT precursor reacted with residual carbon and silicon, diffused from the Si substrate, to form TiCx, TiSix species in the PZT layer during the thermal treatment. A great interface diffusion and chemical reaction took place on the interface of PZT/Si also. The silicon atoms diffused from silicon substrate onto the surface of PZT layer. The oxygen atoms, which came from air, diffused into silicon substrate also and reacted with Si atoms to form a SiO2 interlayer between the PZT layer and the Si (111) substrate. The thickness of SiO2, interlayer was proportional to the square root of treatment time. The formation of the SiO2 interlayer was governed by the diffusion of oxygen in the PZT layer at low annealing temperature, and governed by the diffusion of oxygen in SiO2 interlayer at high annealing temperature. The apparent activation energy of the interface oxidation reaction was about 39.1 kJ/mol.

AbstractThe mass spectrometric behaviour of four cis‐ and trans‐1a,3‐disubstituted‐1,1‐dichloro‐4‐formyl‐1a,2,3,4‐tetrahydro‐1H‐azirino [1, 2‐a][1,5]benzodiazepines has been studied with the aid of mass‐analysed ion kinetic energy spectrometry and exact mass measurements under electron impact ionization. All compounds show a tendency to eliminate a chlorine atom from the aziridine ring, and then eliminate a neutral propene or styrene from the diazepine ring to yield azirino [1,2‐b][1,3] benzimidazole ions. These azirino [1,2‐a][1,5]‐benzodiazepimes can also eliminate HCl, or Cl plus HCl simultaneously to undergo a ring enlargement rearrangement to yield 1,6‐benzodiazocine ions, which further lose small molecular fragments, propyne or phenylacetylene, with rearrangement to give quinoxaline ions.

AbstractThrough one pot reaction of C60 with organocopper/magnesium reagent ( p‐MeC6H4 )2 CuMgBr or ( m ‐ MeC6 H4 )2‐CuMgBr prepared from CuBr‐Me2S and p‐MeC6H4MgBr or m‐MeC6H4 MgBr and subsequent quenching with aqueous NH4Cl, two pentaarylated [ 60 ] fullerene derivatives (p‐MeC6H4)5 C60H (1) and (m‐MeC6H4)5 C60H (2) have been synthesized in 94% and 96% yields, respectively. While known compound 1 prepared via this improved method is unambiguously identified, new compound 2 is fully characterized by elemental analysis, IR, UV‐vis, 1H NMR and 13C NMR spectroscopies. Additionally, electrochemical study shows that the two [60] fullerene derivatives 1 and 2 in dichloromethane solution display two sequential one‐electron reductions which are shifted by about 0.4 V towards more negative potential values with respect to free C60. Such remarkable cathodic shift is attributed to the multiple breakage of the double‐bond conjugation within the Fullerene core.

Authors: Wen‐Sheng Cai , Fang Yu , Xue‐Guang Shao , Zhong‐Xiao Pan 
Published: September 2010

AbstractA modified genetic algorithm with real‐number coding, non‐uniform mutation and arithmetical crossover operators was described in this paper. A local minimization was used to improve the final solution obtained by the genetic algorithm. Using the exp‐6–1 interatomic energy function, the modified genetic algorithm with local minimization (MGALM) was applied to the geometry optimization problem of small benzene clusters (C6H6)N(N = 2–7) to obtain the global minimum energy structures. MGALM is simple but the structures optimized are comparable to the published results obtained by parallel genetic algorithms.

AbstractRapid electron transfer from electron adduct and reducing OH adduct of 2‐deoxyadenosine‐5′‐monophosphate acid (dAMP) to riboflavin (RF) and flavin adenine dinucleotide (FAD) was studied using the time‐resolved pulse radiolysis techniques. Both spectroscope and kinetic analyses showed that transient absorption spectrum of electron adduct or OH adduct of dAMP formed at first, and men changed to that of radical anion of RF or FAD after several microseconds of pulse. The evidence indicated that electron transfer from electron adduct and reducing OH adduct of dAMP to RF or FAD did occur. From buildup or bleaching kinetics of radical anions of RF and FAD, the rate constants for electron transfer were determined, respectively.

AbstractVesicle can be prepared from aqueous mixtures of simple commercially available, single‐tailed cationic and anionic surfactants. In this work, the I3/I1 value, Ie/Im value, and fluorescence lifetime of pyrene in different systems (see the preparation of samples) were determined. The essential affecting factors in the formation of vesicle can be deduced from the obtained results. It showed that large vesicle must form naturally before sanitation in 0.082 M octyltrimethylammonium bromide and sodium laurate pH=9.2 aqueous solution. While after sonication, only small vesicle exists, which can be proved further through electron microscope.

AbstractTwo new intercalation compounds Fe0.90 PS3 (phen)0.41 (1) (phen stands for 1, 10‐phenanthroline including a part of 1, 10‐phenanthroline H+ ) and Fe0.83 PS3 (bipy)0.34 (2) (bipy stands for 2,2′‐bipyridine H+) were synthesized by the reaction of the layered FePS3 with 1, 10‐phenanthroline or 2,2′‐bipyridine in the presence of anilinium chloride. They were characterized by elemental analyses, powder X‐ray diffraction (XRD), infrared spectroscopy. The lattice spacing of the intercalate was expanded by 0.90 nm for Fe0.90 PS3(phen)0.41 and 0.57 nm for Fe0.83 PS3 (bipy)0.34 with respect to the pristine FePS3, indicating that the ring plane of the guests is perpendicular to the layer of the host. The UV‐vis absorption spectra of the filtrate in preparation of the intercalates indicate that 1,10‐phenanthroline or 2,2′‐bipyridine also acts as a complexing agent to remove intralamellar Fe2+ ions into the solution during intercalation. The magnetic properties of 1 and 2 were studied.
