	Abstract:Sulfur-doped Co(OH)2 layered nano-sheet electrode materials were prepared by a simple one-step electrodeposition method using three substances, namely thiourea (TU), thioacetamide (TAA), and N-methylthiourea (N-MTU), as sulfur sources. The morphology, crystallinity, and electronic structure of Co(OH)2 materials changed with different sulfur source doping. Three-electrode electrochemical testing in 2 M KOH showed that the electrochemical performance of the materials improved significantly after being doped with the three kinds of sulfur sources. Among them, the material doped with TU as the sulfur source exhibited the highest specific capacitance (1687.27 F g-1 at 1 A g-1), while the materials doped with TAA and N-MTU as the sulfur sources had specific capacitances of 1478.18 F g-1 and 1007.27 F g-1, respectively. Compared with pure Co(OH)2 (678.18 F g-1 at 1 A g-1), the specific capacitance was significantly improved. The S-Co(OH)2 sample doped with TU was used as the positive electrode and FeOOH@rGO was used as the negative electrode to form an STU-Co(OH)2//FeOOH@rGO ASC, which achieved a high energy density of 61.1 Wh kg-1 at a power density of 800 W kg-1 and still maintained an 83% capacity retention rate after 5000 cycles, demonstrating good practical application ability.

	Abstract:The water-soluble cyclohexanone formaldehyde resins (CFR) are synthesized using the rehydrated magnesium-aluminum hydrotalcite as the catalyst and double bonds are introduced by capping the chain ends with 5-norbornene-2,3-dicarboxylic anhydride. Through monitoring the conversion of double bonds with FT-IR, the UV-curing behavior of unsaturated CFR in the presence of pentaerythritol tetra (3-mercaptopropionate) is studied. The results show that the conversion of double bonds can reach to 64.1% at 0.66 mW/cm2 of UV light intensity when the molar ratio of double bonds to sulfhydryl groups is 1:1 in the presence of benzoin dimethyl ether (1% of molar amount of double bonds). The UV-curing kinetics conforms to the diffusion control model similar to the thermo-curing model of amine-epoxy.

	Abstract:The Ag-Y, Ce-Y and Cu-Y zeolites were successfully prepared for removing corrosive sulfur from transformer insulating oil. The adsorptions and kinetics of corrosive sulfur on Ag-Y, Ce-Y and Cu-Y were studied, and activation energies (Ea) of adsorption processes were calculated. The results show that the desulfurization properties of these three adsorbents were Ag-Y > Ce-Y > Cu-Y, and 0.5wt% Ag-Y adsorption capacity of DBDS and NDM was up to 15.2mg/g and 18.8mg/g respectively. The kinetics for the adsorption process can be described by pseudo-second-order model and adsorption rate constants increase with an increase of temperature, indicating the endothermic nature of the adsorption. The adsorption process on Ag-Y was dominated by chemical adsorption, whereas the adsorption process on Ce-Y was dominated by physical adsorption, and the adsorption on Cu-Y was performed simultaneously by chemical and physical adsorption.

	Abstract:NaY and Na13X zeolites were modified by different modification manners, which are H+ modification, metal ion (copper, nickel or cerium ions) modification and H+ modification followed by metal ion modification, to prepare series of sorbents. The properties of these sorbents were measured by XRD, N2 adsorption and SEM/EDS. The desulfurization activity of these sorbents was evaluated in a model gasoline made of thiophene and cyclohexane, and the results were compared to investigate the effect of preparation methods on adsorption desulfurization behavior. The results show that H+ modification or metal ion modification could all improve the desulfurization efficiency of both NaY and Na13X zeolites, however, for Na13X, after modified by copper or nickel ions, its crystal structure was destroyed, and thus the desulfurization efficiency is much lower than before. The desulfurization activity of the sorbents prepared via H+ modification followed by metal ion modification is higher than that of sorbents prepared by single H+ modification or metal ion modification because pre-modification by H+ can increase the metal content, specific surface and pore volume of sorbent in the following metal ion modification process. Compared with Na13X, NaY is more suitable for H+ modification followed by metal ion modification. Among those prepared sorbents, the CuHY sorbent prepared via NaY modified via H+ and followed by copper ion, has the highest desulfurization efficiency at room temperature.

	5. Investigating and Molecular Understanding of Odd-Even Alternation of the Nucleation Kinetics of Dicarboxylic Acids in Ethanol

	Abstract:Odd-even alternations in thermodynamic properties (melting point, solubility enthalpy, sublimation, etc.) are well-known in the alkyl derivatives. But few attentions are focused on kinetics, which is essential for the design of manufacture process. In this work, the nucleation kinetics of a series of dicarboxylic acids (HOOC-(CH2) n-2-COOH, n=4-12) in ethanol were determined based on induction time measurement at constant supersaturations. The results revealed that the odd-even alternation existed in kinetics as well: odd acids (n=odd) exhibited quicker nucleations compared to the even ones (n=even). We attempted to give insight into the odd-even alternation machenism of nucleation kinetics. Detailed investigations were carried out on molecular arrangements and intermolecular interactions. The energies of intramolecular torsions and intermolecular interacitons were calculated using Materials studio (Accelrys Software Inc.). Relatively higher torsional energy barriers in odd acids crystals and larger interaction energies between odd diacids and ethanol molecules were observed and believed to cause slower nuclei formation of odd acids during solution crystallization compared to even ones. Furthermore, nucleation kinetics is definitely useful for the development of crystallization processes for dicarboxylic acids.this paper.

	Chemical Engineering 25 July 2012
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Using a static analytical model, experimental solubility data were obtained for capsaicin in n-hexane, cyclohexane, carbon disulfide, butyl ether, and isopropyl ether at temperatures ranging from 278.15 K to 323.15 K. The melting temperature and fusion enthalpy of capsaicin were measured using differential scanning calorimetry. The measured solubility data were well correlated by the van't Hoff, modified Apelblat, λh (Buchowski), Wilson, and NRTL models, with the Wilson model showing the best agreement. The activity coefficients of capsaicin and the mixing Gibbs free energies, enthalpies, and entropies of the resulting solutions were predicted based on the Wilson model parameters at measured solubility points. In addition, the infinite-dilution activity coefficients and excess enthalpies of capsaicin were estimated. Finally, the effects of solute-solvent intermolecular repulsive interactions on the solubility behavior and the values of mixing Gibbs free energy were discussed.

	Abstract:Nanoscience and nanotechnology has attracted a great interest in resent years due to its growing impact on many areas such as materials structures, biotechnology, optoelectronics, data storage, microelectronics, micromechanics etc. A variety of chemical and physical procedures have been used to synthesize metal nanostructures. Although these methods could be used successfully to produce metal nanostructures, they involve expensive input, toxic solvents and hazardous chemicals. Therefore, there is increasing need to develop a reliable, nontoxic, cost-effective and eco-friendly approach. Biological approach is timely a promising approach to synthesize metal nanostructures. However, the research on biosynthesis of metal nanostructures still remains to simple conditional experiments and the characterization of the metal nanostructures hitherto, and the mechanism of reduction of metal nanoparticles is still not well understood. Therefore, this review provides an overview on the biosynthesis of metal nanostructures by plants, bacteria and fungi. The current application and prospects of biological synthesis of metal nanostructures are also presented.
