3Studies on the solid state reactions of coordination conpounds——XLⅤⅢ.The effect of KSCN on the thermal decomposition of cobalt(Ⅲ)-ammine complexes显示文摘The evolved gaseous analysis (EGA),infrared spectra,and XRD have been appliedto the study of solid state reactions of KSCN with five cobalt(Ⅲ)-ammine complexes:[Co-(NH3)5N3]Cl2,[Co(NH3)5(NO2)]Cl2,[Co(NH3)5(H2O)]Cl3,[Co(NH3)5Cl]Cl2,and [Co(NH3)6]Cl3in a hydrogen atmosphere.It is found that the existence of KSCN shifts the thermal decom-position of these complexes to a lower temperature.The corresponding peak temperatures arenear 140℃.The effect of KSCN is discussed and kinetic parameters of deammine reactionsare calculated.ZHENG,Li-Min XIN,Xin-Quan Coordination Chemistry Institute,Nanjing University,Nanjing 210008 Part XLVⅡ of this series:Chin.J.Chem.,11,21(1993) 1993Chinese Journal of Chemistry1993,11,3:7
4ON THE AGE OF THE PAOMAGANG FORMATION IN THE JIANGHAN BASIN,HUBEI, CHINA显示文摘The Paomagang Formation in the Jianghan Basin, Hubei Province, is a sequence of continental deposits consisting mainly of brownish-red mudstone and siltstone. Its age is generally referred to as the late Late Cretaceous, though some geologists suggest that it partly belongs to the Early Tertiary. Up to now no one can show where the Cretaceous-Tertiary boundary is, whether or not the Paleocene exists and, if it does, how thick the interval is.李伟同 1985Chinese Science Bulletin1985,30,11:4
5ABOUT THE INVERSION FORMULA ON THE LIE GROUP SL (2, R)显示文摘Harish-Chandra have got a Fourier inversion formula for C_c^-(SL(2, R)). In this paper, we give a discussion on approximation identity kernels on SL(2, R) and get some properties of their Fourier transforms, and then, making use of these properties and Harish-Chandra’s result, we prove that the Fourier inversion formula obtained by Harish-Chandra is also valid for C_b^3 (SL(2, R)).肖昌柏 1993Acta Mathematica Scientia1993,13,4:3
6Bat origin of a new human coronavirus:there and back again显示文摘A novel coronavirus reported to cause pneumonia in 41 people during December 2019 in Wuhan,the capital of Hubei province,China,was identified and designated as the 2019 novel coronavirus(2019-nCoV)(Zhu et al.,2020;Li et al.,2020).Infection with 2019-nCoV results in clusters of severe respiratory illness similar to that caused by severe acute respiratory syndrome coronavirus(SARS-CoV)and is associated with high mortality(Chen et al.,2020;Huang et al.,2020).This new coronavirus belongs to genus Betacoronavirus,family Coronaviridae,with a single-stranded,positive-sense RNA genome,but genetically distinct from SARS-CoV and Middle East respiratory syndrome coronavirus(MERS-CoV).Xiang Li Yuhe Song Gary Wong Jie Cui 2020Science China(Life Sciences)2020,63,3:3

12POLY (β-HYDROXYALKANOATES): NATURAL BIOCOMPATIBLE AND BIODEGRADABLE POLYESTERS PRODUCED BY BACTERIA显示文摘A wide variety of different types of microorganisms are known to produce intracellular energy and carbon storage products, which have been generally described as being poly (β-hydroxybutyrate), PHB, but which are, more often than not, copolymers containing different alkyl groups at the β-position. Hence, PHB belongs to the family ofpoly (β-hydroxyalkanoastes), PHA, all of which are usually formed as intracellular inclusions in bacteria under unbalanced growth conditions. Recently, it became of industrial interest to evaluate these PHA polyesters as natural biodegradable and biocompatible plastics for a wide range of possible applications, such as surgical sutures or packaging containers. For industrial applications, the controlled incorporation of repeating units with different chain lengths into a series of copolymers is desirable in order to produce polyesters with a range of material properties because physical and chemical characteristics depend strongly on the polymer composition. Such 'tailor-made' copolymers can be produced under controlled growth conditions in that, if a defined mixture of substrates for a certain type of microorganisms is supplied, a well defined and reproducible copolymer is formed.ROBERT W. LENZ RICHARD A. GROSS HELMUT BRANDL R. CLINTON FULLER 1989Chinese Journal of Polymer Science1989,7,4:2

19Structural insights into the activation of GLP-1R by a small molecule agonist显示文摘Dear Editor,The glucagon-like peptide-1 receptor(GLP-1R)belongs to class B G protein-coupled receptors(GPCRs).It is a clinically proven target for type 2 diabetes and obesity.1 Several peptidic drugs have been approved including one in pill form,the oral semaglutide.Despite these advances,oral non-peptidic medicines have been pursued across the pharmaceutical industry for improved patient compliance with reduced side effects such as nausea and vomiting.1 The discovery of non-peptidic drugs has been hampered for many years,primarily owing to the difficulty of mimicking the peptide-receptor interactions with small molecule non-peptidic agonists.Honglei Ma Wei Huang Xiaoxi Wang Lihua Zhao Yi Jiang Feng Liu Wei Guo Xianqiang Sun Wenge Zhong Daopeng Yuan HEric Xu 2020Cell Research2020,30,12:1
