Dependence of Elution Curve and Adsorption Isotherms of Insulin on Composition of Mobile Phase of Frontal Analysis in Reversed Phase Liquid Chromatography
Authors: Xin‐Du Geng , Fred E Regnier 
Published: September 2010

AbstractWith frontal analysis (FA), the dependence of adsorption isotherms of insulin on the composition of mobile phase in reversed phase liquid chromatography (RPLC) has been investigated. This is also a good example to employ the stoichiometric displacement theory (SDT) for investigating solute adsorption in physical chemistry. Six kinds of mobile phase in RPLC were employed to study the effects on the elution curves and adsorption isotherms of insulin. The key points of this paper are: (1) The stability of insulin due to delay time after preparing, the organic solvent, concentration, the kind and the concentration of ion‐pairing agent in mobile phase were found to affect both elution curve and adsorption isotherm very seriously. (2) To obtain a valid and comparable result, the composition of the mobile phase employed in FA must be as same as possible to that in usual RFLC of either analytical scale or preparative purpose. (3) Langmuir Equation and the SDT were employed to imitate these obtained adsorption isotherms. The expression for solute adsorption from solution of the SDT was found to have a better elucidation to the insulin adsorption from mobile phase in RPLC.

Authors: Fa‐Liang Cheng , Shan Du , Bao‐Kang Jin 
Published: September 2010

AbstractSingle‐wall carbon nanotubes (SWNTs) modified gold electrodes were prepared by using two different methods. The electrochemical behavior of cytochrome c on the modified gold electrodes was investigated. The first kind of SWNT‐modified electrode (noted as SWNT/Au electrode) was prepared by the adsorption of carboxylterminated SWNTs from DMF dispersion on the gold electrode. The oxidatively processed SWNT tips were covalently modified by coupling with amines (AET) to form amide linkage. Via Au—S chemical bonding, the self‐assembled monolayer of thiol‐unctionalized nanotubes on gold surface was fabricated so as to prepare the others SWNT‐modified electrode (noted as SWNT/AET/Au electrode). It was shown from cyclic voltammetry experiments that cytochrome c exhibited direct electrochemical responses on the both electrodes, but only the current of controlled diffusion existed on the SWNT/Au electrode while both the currents of controlled diffusion and adsorption of cytochrome c occurred on the SWNT/AET/Au electrode. Photoelastic Modulation Infared Reflection Absorption Spectroscopy (PEM‐IRRAS) and Quartz Crystal Microbalance (QCM) were employed to verify the adsorption of SWNTs on the gold electrodes. The results proved that SWNTs could enhance the direct electron transfer process between the electrodes and redox proteins.

Authors: Jian Zhang , Bryant Lonnee 
Published: September 2010

AbstractThis paper describes the synthesis, surface tension and dispersancy properties of block copolymer nonionic surfactants comprised of polyethyleneimine (PEI) and polyethylene oxide (PEO) blocks of selected lengths. These block copolymers were prepared by a threestep synthetic sequence. Firstly, PEO glycol was converted to its dimethanesulphonylester (dimesyl) derivative by reacting with methanesulphonyl chloride. Then a tri‐block polymer was prepared by the ring‐opening polymerization of 2‐methyl‐2‐oxazoline (MeO‐ZO) with the dimesyl PEO derivative. Lastly, linear PEI blocks were obtained by subsequent hydrolysis and purification. 1H NMR spectra confirmed the structures of the intermediate, final products and their purities (> 99%). The utility of these block copolymers is described in terms of their surface tension and day dispersancy measurements as a function of copolymer chain and block length.

Published: September 2010

AbstractA new fluorinated polystyrene bearing a p‐substituted perfluoro[1‐(2‐fluorosulfonylethoxy)] ethyl group was synthesized via one‐electron oxidation of polystyrene by perfluoro [2‐(2‐fluorosulfonylethoxy)] propionyl peroxide at different peroxide to polystyrene molar ratios. The yield of perfluoroalkylation decreases with the increase of the reactant molar ratio. The modified polymer has been characterized by various techniques: the ring perfluoro[l‐(2‐fluorosulfonylethoxy)] ethylation has been proved by FT‐IR and 19F NMR; the X‐ray photoelectron spectra (XPS) show the maximum binding energy of Fls, Ols Cls(two kinds of carbon atoms, namely C‐H and C‐F) and S2p, respectively; desulfonylation of the fluorinated polystyrene appearing at 217 °C has been found by its thermogravimetric analysis (TGA). The determinations of contact angle, refractive index and glass transition temperature of the modified polymer have disclosed that when the contact angle increases with the increase of the molar ratio, the refractive index and glass transition temperature decrease. The polydispersity values indicate that the degradation of the polymer chains did not occur during the reaction.
Cloud Points of Water‐soluble Polyether Phosphites and Their Application in the Biphasic Hydroformylation of Higher Olefins
Authors: Xiao‐Zbong Liu , Yan‐Hua Wang , Fan‐Zhi Kong , Zi‐Lin Jin 
Published: September 2010

AbstractWater‐soluble polyether phosphites alkyl polyethylene glycol o‐phenylene phosphite (APGPPs) were easily prepared via alcoholysis of phosphorus chloride with polyoxyethylene alkyl ether. With appropriate HLB (hydrophile‐lypophile balance), the phosphites possess clear cloud points below 100 °C. Addition of some inorganic salts decreases cloud points of the phosphites. When the phosphites have long polyether chain binding to short‐chain alkyl group, their cloud points could be extrapolated from figure of dependence of cloud points on addition of inorganic salts. Utilizing octylpolyglycol‐phenylene‐phosphite (OPGPP) (APGPP, R: Octyl)/Rh complex formed in situ as catalyst, over 90% conversion of 1‐decene was obtained, avoiding the limitation of water insolubility of substrates. Preliminary results indicated that micellar catalysis and thermoregulated phase‐transfer catalysis (TRPTC) coexist in the reaction system. Below cloud point, micellar catalysis induced by polyether phosphites may be existed. When temperature is increased to above cloud point of the phosphites, this reaction works mainly in TRPTC. The catalysts could be easily separated by simple decantation, but followed by considerable loss in activity after three successive reaction runs. Preliminary results indicated hydrolysis of OPGPP happened during the reaction, which may explain for the bad loss in activity. The catalyst was reused up to seven times without clear decrease in activity when OPGPP/Rh ratio was increased to 50.

Electrochemical and Spectroscopic Study on the Interaction of Cytochrome c with Anionic Lipid Vesicles
Authors: Wei‐Guo Jing , Chang‐Wei Liu , Ji‐Lin Tang , Zheng‐Yan Wu , Shao‐Jun Dong , Er‐Kang Wang 
Published: September 2010

AbstractThe structure and the electron‐transfer of cytochrome c binding on the anionic lipid vesicles were analyzed by electrochemical and various spectroscopic methods. It was found that upon binding to anionic lipid membrane, the formal potential of cytochrome c shifted 30 mV negatively indicating an easier redox interaction than that in its native state. This is due to the local alteration of the coordination and the heme crevice. The structural perturbation in which a molten globule‐like state is formed during binding to anionic lipid vesicles is more important. This study may help to understand the mechanism of the electron‐transfer reactions of cytochrome c at the mitochondrial membrane.

AbstractA new biomimetic bulk acoustic wave sensor based on molecularly imprinted microspheres (MIM) technique was described. The sensing materials were synthesized by precipitation polymerization. By using the Scatchard analysis, the equilibrium dissociation constant KD and the apparent maximum number Qmax of the binding sites were calculated to be 3.70 mmol·L−1 and 9.11 μmol·g−1, respectively. The sensor exhibited a sensitive response to the template compound (dipyridamole) in liquid phase with a detection limit of 2 × 10–9 mol· L−1. The recoveries of the sensor were 95.1%‐105.4%. Studies presented in this paper show that the stability of this sensor is excellent. The sensor has been applied successfully to the determination of dipyridamole in human urine.

AbstractTwo new mixed‐ligand ruthenium(II) complexes, Ru(dcbpy)‐(LL) (NCS)2[where dcbpy = 4, 4′‐dicarboxyl‐2,2′‐bipyridine, LL = 4,4′‐bis (N‐methyl‐anilinomethyl)‐2,2′‐bipyridine (1) or 4‐methyl‐4′‐N‐methyl‐anilinomethyl‐2,2′‐bipyridine (2)], were synthesized, and the photophysical properties of these complexes were studied. The metal‐to‐ligand charge transfer (MLCT) transitions of these complexes exhibited solvatochromic effect due to the existence of NCS ligands. The MLCT energies also strongly depend on the pH values of the solutions because of protonation and deprotonation of the carboxyl groups. The pKa, values of the ground state, 4.0 for 1 and 3.8 for 2, were obtained from the titration curves. The photoelectrochemical properties of 1 and 2 as sensitizers in sandwich‐type solar cells have been studied. Complex 1 exhibited better photoelectrochemical behavior than complex 2 as expected. It was proved that the design of mixed‐ligand complex by introducing electron donating group in one of the ligands should be a promising approach.
