| 1 | Quantum phase transition and entanglement in Li atom system显示文摘By use of the exact diagonalization method, the quantum phase transition and en- tanglement in a 6-Li atom system are studied. It is found that entanglement appears before the quantum phase transition and disappears after it in this exactly solvable quantum system. The present results show that the von Neumann entropy, as a measure of entanglement, may reveal the quantum phase transition in this model. | SI LiMing1 & HOU JiXuan2 1 Department of Electronic Engineering, School of Information Science and Technology, Beijing Institute of Technology, Beijing 100081, China 2 Laboratoire de Chimie, UMR 5182 CNRS, Ecole Normale Supérieure de Lyon, 46, Allée d’Italie, F-69364 Lyon Cedex 07, France | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，11： | 6 |
| 2 | Preparation and Properties of Zirconium Hydrideon the surface of MCM-41 Mesoporous Molecular Sieves显示文摘Zirconium monohydride bonded to the framework oxygen of MCM-41 surface was prepared by the reaction of tetraneopentyl zirconium with MCM-41 surface hydroxyl groups, followed by the hydrogenolysis of the resulted product. The surface hydride was characterized by using infrared spectroscopy, solid-state NMR, elemental analysis, gas-phase chromatography and chemical probing reaction. It was shown that this surface species is stable below 150 'C and can catalytically crack alkanes into methane and ethane at 100 . | WANG Xu-xu1* * , FU Xian-zhi1, LEFEBVRE Frederic2 and BASSET Jean-Marie2(1.

| 7 | PEG-related polymer resins as synthetic supports显示文摘Combinatorial chemistry has become a significant part of the discovery and optimization process for novel drugs,affinity ligands,and catalysts.The polymeric supports play a key role in combinatory chemistry.Therefore,various kinds of functional polymer resins have been exploited as supports,reagents,and catalysts in organic synthesis.In comparison to the conventional Merrifield resins,the poly(ethylene glycol)(PEG)-related polymer resins have advantages including good compatibilities with polar solvents,good solvent absorbency and swelling properties.This review focuses primarily on the more recent work in the field of developing PEG-related polymer resins as supports for organic synthesis. | WANG Zheng1,YANG RuLei1,ZHU JunDong & ZHU XiaoXia2 1School of Pharmaceutical Science and Technology,Tianjin University,Tianjin 300072,China 2Département de chimie,Université de Montréal,Montréal,QC H3C 3J7,Canada | 2010 | Science China Chemistry2010，53，9： | 1 |
| 8 | Methodology of factorial design deriving guidelines for simulation of growth curve and production of sugars by Spirulina (Arthrospira) maxima显示文摘It is practical, economic and sometimes essential to derive rules or conclusions by performing lesser runs of experiments. In this part, a methodology based on 2 f factorial design was brought up to derive guidelines to simulate growth curve and production of sugars by Spirulina (Arthrospira) maxima . The growth curve or accumulation process of sugars was idealized by sets of straight lines limited by phase transfers of growth or accumulation of sugars. Normal analyses of the critical values of the transfers were used to derive their linear relationships with the initial conditions of the experimental factors. These linear functions were called guidelines and were used to simulate the growth curve or accumulation of sugars. Generalization of the guideline technique was determined by the kinetic limitation of nutrient nitrogen or sulfur that was dependent upon their stoichiometric deficiency directly derived from their initial values in the medium. This method uses the initial conditions of culture and does not need measurements of concentrations of nitrate, sulfate and pigments during cultivation. It is a practical and useful alternative way to trace and predict approximately the growth curve and production of sugars by S. maxima . | NIE Zhen yuan 1,XIA Jin lan 1* , LEVERT J.M. 2 (1.Institute of Bioengineering, Department of Mineral Engineering, Central South University, Changsha 410083, China 2.Service de Chimie et Biochimie Appliquées, Faculté Polytechnique de Mons, | 2001 | Journal of Central South University of Technology2001，8，4： | 1 |

Bile acids are amphiphilic molecules biosynthesized in the liver. They are used to prepare various polymers and oligomers. These polymers made of bile acids are promising materials in both biomedical and pharmaceutical fields. | ZHANG JiaWei1 & ZHU XiaoXia2 1 Institute of Polymer Chemistry, Nankai University, Tianjin 300071, China 2 Département de Chimie, Université de Montréal, Montréal, QC, H3C 3J7, Canada | 2009 | Science China Chemistry2009，52，7： | 1 |
| 14 | DESIGN AND STUDY OF NEW AZOBENZENE LIQUID CRYSTAL/POLYMER MATERIALS显示文摘Discussion is presented on the use of the photoisomerization of azobenzene chromophore in the design and preparation of novel functional materials. The two systems reviewed are azobenzene polymer-stabilized liquid crystals and azobenzene elastomers. In the first case, a polymer network containing azobenzene moieties is used to optically induce and stabilize a long-range liquid crystal orientation without the need of treating the surfaces of the substrates. This optical and rubbing-free approach was applied to nematic and ferroelectric liquid crystals. In the second case, an azobenzene side-chain liquid crystalline polymer is grafted onto a styrene-butadiene-styrene triblock copolymer to yield a photoactive thermoplastic elastomer. Coupled mechanical and optical effects make possible the formation of diffraction gratings that may be useful for mechanically tunable optical devices. | Yue Zhao Departement de chimie, Universite de Sherbrooke.
