摘要：Expanding the optical absorption range of photocatalysts is still a key endeavor in graphitic carbon nitride(g-C_(3)N_(4))***,we report on a novel thiophene group extending the optical property,which is assigned to n-π^(*)electronic transitions involving the two lone pairs on sulfur(TLPS).The as-prepared samples,denoted as CN-ThAx(where x indicates the amount of ThA added,mg),showed an additional absorption above 500 nm as compared to pristine g-C_(3)N_(4).Further,the thiophene group enhanced charge carrier separation to suppress e‒/h+pair *** experimental results suggest that the thiophene group can obstruct the polymerization of melem to generate a large plane,thus exposing the lone electron pairs on the *** photocatalytic activity was evaluated in the decomposition of bisphenol A and H2 *** with g-C_(3)N_(4),the optimized CN-ThA_(30) sample led to a 6.6-and 2-fold enhancement of the degradation and H2 generation rates,*** CN-ThA_(30) sample allowed for synchronous H2 production and BPA decomposition.

摘要：为探究宁夏野生岩羊(Pseudois nayaur)小反刍兽疫病毒(Peste des petits rumi-nants virus,PPRV)的分子遗传特征,根据Gen Bank公布的PPRV基因组序列设计并合成13对全基因组扩增引物,通过RT-PCR和DNA测序及拼接获取毒株(wild-bharal/China-NXYH/2021株)全基因组序列,借助DNASTAR和MEGA 7.0软件进行序列分析。结果显示:该毒株属于基因Ⅳ系,基因组全长为15954 nt;在系统进化上,与2013年以来中国流行株和2016—2017年蒙古流行株亲缘关系较近,共同组成一个小的进化分支;在全基因组一致性分析中,与国内新疆流行株goat/China-XJYL/2013一致性最高(99.4%),与国内其他野生动物PPRV株wild-bharal/China-Tibet/2008、Ibex/China-XJBZ/2015和Procapra-przewalskii/China-GS/2018的一致性分别为96.8%、98.8%和99.0%。在H和F蛋白氨基酸多态性分析中,发现该毒株H和F蛋白中均出现了独特的氨基酸突变,分别为H蛋白的R285Q、S421R和F蛋白的R/K/T3W、Q305R。结果表明,小反刍兽疫病毒已传入宁夏野生动物种群,为我国小反刍兽疫根除工作带来新的困难和挑战,需加强对宁夏野生动物PPRV感染情况的追踪和监测,以便及时从传染源和传播途径方面阻断PPRV的传播。
