2Preparation of polypropylene/montmorillonite nanocomposites by intercalative polymerization:Effect of in situ polymer matrix functionalization on the stability of the nanocomposite structure显示文摘The copolymerization of propylene and 5-hexenyl-9-borabicyclo[3.3.1]nonane (5-hexenyl-9-BBN) has been conducted with an MgCl2/TiCl4 catalyst intercalated in an organically modified montmorillonite (OMMT) with triethylaluminum (AlEt3) cocatalyst and diphenyldimethoxysilane (DDS) external donor. This polymerization process simultaneously results in both the exfoliation of MMT layers to realize the preparation of polypropylene (PP)/MMT nanocomposites and the implantation of reactive borane groups in the formed PP matrix. The polymer-borne borane groups have been able to undergo an effi-cient hydrolysis process under very mild reaction conditions (40℃, 3 h, in THF), introducing hydroxy groups into PP without sacrificing the polymerization-formed nanocomposite structure (the exfoliation of MMT). The resultant hydroxyl-functionalized PP/MMT nanocomposites exhibit enhanced structural stability against processing compared with those based on unfunctionalized PP matrix.YANG KeFang HUANG YingJuan DONG JinYong 2007Chinese Science Bulletin2007,52,2:9

4Human T-cell immunity against the emerging and re-emerging viruses显示文摘Over the past decade, we have seen an alarming number of high-profile outbreaks of newly emerging and re-emerging viruses.Recent outbreaks of avian influenza viruses, Middle East respiratory syndrome coronaviruses, Zika virus and Ebola virus present great threats to global health. Considering the pivotal role of host T-cell immunity in the alleviation of symptoms and the clearance of viruses in patients, there are three issues to be primarily concerned about T-cell immunity when a new virus emerges: first, does the population possess pre-existing T-cells against the new virus through previous infections of genetically relevant viruses; second, does a proper immune response arise in the patients to provide protection through an immunopathogenic effect; lastly, how long can the virus-specific immune memory persist. Herein, we summarize the current updates on the characteristics of human T-cell immunological responses against recently emerged or re-emerged viruses, and emphasize the necessity for timely investigation on the T-cell features of these viral diseases, which may provide beneficial recommendations for clinical diagnosis and vaccine development.Min Zhao Hangjie Zhang Kefang Liu George F.Gao William J.Liu 2017Science China(Life Sciences)2017,60,12:6

6Omicron variant of SARS-CoV-2 imposes a new challenge for the global public health显示文摘Since its first discovery,the Omicron variant of severe acute respiratory syndrome coronavirus 2(SARS‐CoV‐2)has evoked another wave of infection and caused global concern and panic.Moreover,although the data are still limited,Omicron showed highly concerning characteristics,including higher transmissibility,extensive immune escape and potentially altered host range.We interpreted these characteristics based on currently available data and outlined some urgent questions,calling for a more comprehensive investigation.Zepeng Xu Kefang Liu George F.Gao 2022Biosafety and Health2022,4,3:1
