Hydrophobically modified polyelectrolytes: I. Dilute solution properties of fluorocarbon‐containing poly (acrylic acid)
Authors: Hui Zhou , Guo‐Qiang Song , Yun‐Xiang Zhang , Ma Deeing, Reinhold , Lukas Lian Haeussling 
Published: September 2010

AbstractDilute solution viscosity of fluorocarbon‐containing hydrophobically modified poly (acrylic add) was measured in aqueous solutions of various NaCl concentrations. The intrinsic viscosity ([η]) and Huggins coefficient (kH) were evaluated using Huggins equations. It is found that, at low Nacl concentration, the modified polymers exhibit values of intrinsic viscosity ([η]) and Huggins coefficient (kH) similar to those of unmodified polymers. For both of the modified and unmodified polymers, the intrinsic viscosity decreases with increase of NaCl concentration, while the Huggins coefficient increases upon addition of NaCl. But the variation of [η] and kH is more significant for the modified polymers, which reflects the enhanced intra‐ and intermolecular hydrophobic association at higher Nacl concentration.
Effects of Pt diffusion barrier layer on the interface reaction and electric properties of PZT film/Si(111) sample
Authors: Yong‐Fa Zhu , Pei‐Yu Yan , Tao Yi , Li‐Li Cao , Long‐Tu Li 
Published: September 2010

AbstractThe effects of the Pt diffusion barrier layer on the interface diffusion and reaction, crystallization, dielectric and ferroelectric properties of the PZT/Si(111) sample have been studied using XPS, AES and XRD techniques. The results indicate that the Pt diffusion barrier layer between the PZT layer and the Si substrate prohibits the formation of TiCx, TiSix and SiO2 species in the PZT layer. The Pt barrier layer also completly interrupts the diffusion of Si from the Si substrate into the PZT layer and impedes the diffusion of oxygen from air to the Si substrate greatly. Although the Pt layer can not prevent completely the diffusion and reaction between oxygen and silicon, it can prevent the formation of a stable SiO2 interface layer on the interface of PZT/Si. The Pt layer reacts with silicon to form PtSix species on the interface of Pt/Si, which can intensify the chemical binding strength between the Pt layer and the Si substrate. To play a good role as a diffusion barrier layer, the Pt barrier layer must be not thinner than 140 nm. The existence of the Pt layer not only promotes the crystallization of PZT layer to form a perovskite phase but also improves dielectric and ferroelectric performances of the PZT layer.

The temperature dependence of the magnetic susceptibility for Gd(III) and radical was measured (2—‐300 K). The observed data were successfully simulated giving the exchange integral J = 0.28 cm−1, J' = ‐ 0.33 cm−1. These results indicate a weak ferromagnetic spin exchange interaction between Gd(III) ion and the radical and a weak antiferromagnetic spin exchange interaction between the radical and radical.

Authors: Jin‐Fang Wang , Liang‐Mo Zhou , Xue‐Liang Liu , Qing‐Hai Wang , Dao‐Qian Zhu 
Published: September 2010

AbstractMolecular imprinting polymers (MIPs) against N‐Cbz‐L‐Tyr were prepared utilizing different polymer systems and evaluated in HPLC mode. It was found that MIP utilizing cocktail functional monomers, acrylamide + 2‐vinylpyridine showed better molecular recognition and better separation ability for the template molecule than those utilizing other functional monomers. MIP utilizing trimethylolpropane trimethacrylate as cross‐linker showed higher load capacity and separation factor than those utilizing ethylene glycol dimethacrylate as cross‐linker. Increasing the concentration of competing solvent, acetic acid weakened me ionic interaction and hydrogen bonding between the analyte and the functional monomers, 2‐vinylpyridine and acrylamide, when me template enantiomer was separated by HPLC. Therefore increasing of the concentration of acetic acid leads to decreasing of capacity factor, separation factor and resolution.
Synthesis, structures and magnetic properties of a series of polynuclear copper(II)‐lanthanide( III) complexes assembled with carboxylate and hydroxide ligands
Authors: Chen Xiao‐Ming , Yang Yang‐Yi 
Published: September 2010

AbstractHeterometallic copper(II)‐lanthanide(III) complexes have been made with a variety of exclusively O‐donor ligands including betaines (zwitterionic carboxylates) and chloroacetate, which are dinuclear CuLn, tetranuclear Cu2Ln2, pentanuclear Cu3Ln2, and octadecanuclear Cu12 complexes. The results show that subtle changes in both the carboxylates and acidity of the reaction solution can cause drastic changes in the structures of the products. Magnetic studies exhibit that shielding of the Ln3+ 4f electrons by the outer shell electrons is very effective to preclude significant coupling interaction between the Ln3+ 4f electrons and Cu2+ 3d electrons in either a mono‐atomic hydroxide‐bridged, or a carboxylate‐bridged system.

Published: September 2010

AbstractA series of three‐way catalysts (TWCs), containing a small amount of precious metals (PMs, including Pt, Pd and Rh) and a large amount of promoters CeO2and La2O3, were prepared with different precursor compounds and various doped manners. Crystal phases, dispersion of cerium and lanthanum, textural structure and thermal stability of the catalysts were investigated by XRD, XPS and pore parameters determination. The catalytic performance was studied by the measurements of CO, C3H6and NO conversions on dependence of temperature at stoichimetric number point (S =1.00), and fromS= 0.75 to 1.30 at 280°C or 340°C for fresh or aged samples, respectively. The correlation between the catalytic performance and the characteristics of fresh and aged samples were discussed. The results show mat the sample, in which CeO2and La2O3are doped with mixed oxide powders, possesses poor dispersion and less thermal stability, and the conversions of NO and C3H6are apparently lower man those of the samples aged at 850°C The main reason is due to the lanthanum enrichment on the surface. The precious metals and cerium may be covered and enveloped, and the PMs located on the internal microporous surface where no cerium and lanthanum exist, are easier to sinter and oxidize. For the sample doped with La(NO3)3and Ce(NO3)3aqueous solutions, high dispersion and thermal stable CeO2‐La2O3solid solution on all the surface of microporous γ‐Al2O3is identified. The solid solution CeO2La2O3also possessed high dispersion in Ok sample doped with La2O3powder and Ce(NO3)3aqueous solution. The last two aged samples keep higher NO conversion atS≥1 region.

Synthesis of mesoporous silica materials with ascorbic acid as template via sol‐gel process
Authors: Pang Jie‐Bin , Qiu Knn‐Yuan , Wee Yen 
Published: September 2010

AbstractMesoporous silica materials with pore diameters of 2–5 nm have been prepared using ascorbic add as a nonsurfactant template or pore‐forming agent in HCl‐catalyzed sol‐gel reactions of tetraethylorthosilicate, followed by removing the ascorbic acid compound by extraction with ethanol. Characterization results from nitrogen sorption isotherm, powder X‐ray diffraction and transmission electron microscopy indicate that me materials have large specific surface areas (e.g. 1000 m2/g) and pore volumes (e.g. 0.8 cm3/g). The mesoporosity is arisen from interconnecting disordered wormlike channels and pores with relatively broad size distributions. As the ascorbic acid concentration is increased, the pore diameters and pore volumes of the materials increase.

Published: September 2010

AbstractThe reduction and the oxidation of hypophosphite on a Ni‐Ag electrode have been studied to provide the information about the phosphorus incorporation mechanisms during the electro‐less deposition and the electrodeposition of Ni‐P alloys. In the electrooxidation process, an absorbency band around 240 nm, which was ascribed to tbe formation of an intermediate PHO2, was observed by in situ UV‐Vis subtractive reflectance spectroscopy. Accordingly, the electrooxidation of hypophosphite might undergo an H abstraction of hypophosphite from the PH bond to form the phosphorus‐centred radical PHO2, which was subsequently electrooxidized to the final product, phosphite. In the reduction process Ni‐phosphine compound N‐(PH3), was observed byin situ surface Raman spectroscopy. The results from the Raman experiments show that, in the NiSO4‐free solution, hypophosphite was reduced only to Ni‐phosphine compound, while in the case where NiSO4 coexisted in tbe solutions, the Ni‐phosphine compound, as an intermediate, was oxidised by Ni2+ to elemental phosphorus in alloys with nickel acting as the catalyst.

AbstractCyclopentadienyl cobalt complexes (η5‐C5H4R) CoLI2 [L = CO,R=‐COOCH2CH=CH2 (3); L=PPh3, R=‐COOCH2‐CH=CH2 (6); L=P(p‐C6H4O3)3, R = ‐COOC(CH3) = CH2 (7), ‐COOCH2C6H5 (8), ‐COOCH2CH = CH2 (9)] were prepared and characterized by elemental analyses, 1H NMR, ER and UV‐vis spectra. The reaction of complexes (η5‐C5H4R)CoLI2 [L= CO, R= ‐COOC(CH3) = CH2 (1), ‐COOCH2C6H5(2); L=PPh3, R=‐COOC (CH3) = CH2 (4), ‐COOCH2C6H5 (5)] with Na‐Hg resulted in the formation of their corresponding substituted cobaltocene (η5‐C5H4R)2 Co[R=‐COOC(CH3) = CH2 (10), ‐COOCH2C6H5 (11)]. The electrochemical properties of these complexes 1–11 were studied by cyclic voltammetry. It was found that as the ligand (L) of the cobalt (III) complexes changing from CO to PPh3 and P(p‐tolyl)3, their oxidation potentials increased gradually. The cyclic voltammetry of α,α′‐substituted cobaltocene showed reversible oxidation of one electron process.

Ab initio and density functional theory studies of the structure, gas‐phase acidity and aromaticity of tetraselenosquaric acid
Authors: Zhou Li‐Xin 
Published: September 2010

AbstractResults of ab initio self‐consistent‐field (SCF) and density functional theory (DFT) calculations of the gas‐phase structure, acidity (free energy of deprotonation, ΔG*) and aromaticity of tetraselenosquaric acid (3, 4‐diselenyl‐3‐cyclobutene‐1,2‐diselenone, H2 C4 Se4)are reported. The global minimum found on the potential energy surface of tetraselenosquaric acid presents a planar conformation. The ZZ isomer was found to have the lowest energy among the three planar conformers and the ZZ and ZE isomers are very dose in energy. The optimized geometric parameters exhibit a bond length equalization relative to reference compounds, cyclobutanediselenone, and cyclobutanediselenol. The computed aromatic stabilization energy (ASE) by homodesmotic reaction is ‐77.4 (MP2(fu)/6–311+G** /RHF/6 ‐ 311 + G** ) and ‐ 54.8 kJ/mol (B3LYP/6 ‐ 311 + G** //B3LYP/6 ‐311 + G**). The aromaticity of tetraselenosquaric acid is indicated by the calculated diamagnetic susceptibility exaltation (A) ‐19.13 (CSGT(IGAIM)‐RHF/6–311 + G**// RHF/6–311 + G** and ‐32.91 (4π·10−6 m−3/mol)(CSGT(I‐GAIM)‐B3LYP/6 ‐ 311 + G* * //B3LYP/6 ‐ 311 + G**). Thus, tetraselenosquaric acid fulfils the geometric, energetic and magnetic criteria of aromaticity. The calculated gas‐phase acidity is ΔG1*(298k) = 1257.7 and ΔG*2 (298k) = 1617.1 kJ/mol. Hence, tetraselenosquaric acid is the strongest acid among the three squaric acids (3, 4‐dihydroxy‐3‐cyclobutene‐1, 2‐dione, H2 C4 3,4‐dithiohydroxy‐3‐cyclobutene‐1,2‐dithione, H2C4 S4, 3, 4‐diselenyl‐3‐cyclobutene‐1,2‐diselenone, H2C4Se4).
