Micro-electrolysis(ME)technology is investigated for improving the efficiency of removal of pentavalent antimony(Sb(V))from the *** this study,an ME system composed of scrap iron filings,waste manganese fillings,and activated carbon(Fe-Mn-C ME)was used to efficiently remove Sb(V).The results proved that,compared with conventional iron-carbon micro-electrolysis(Fe-C ME),Fe-Mn-C ME significantly enhances the removal rate of Sb(V)when the hydraulic retention time is 10–24 *** Fe-Mn flocs produced by this system were analyzed using X-ray diffraction(XRD),energy-dispersive X-ray spectroscopy(EDS),X-ray photoelectron spectroscopy(XPS),and Brunauer-Emmett-Teller(BET)surface area analysis,which revealed that the flocs were mostly Mn-substituted FeOOH and had a relatively larger specific surface area,providing better adsorption ***,it was found that the removal rate of Sb(V)decreased as the iron-carbon mass ratio increased,while it first increased and then decreased as the manganese content *** reduction of Fe(III)was accelerated with an increase in the addition of manganese,leading to an increase in the concentration of Fe(II).The electron transfer and the formation of Fe(II)were facilitated by the potential difference between manganese and carbon,as well as by the formation of microcells between iron and manganese,which improved the reduction ability of Sb(V).From our thorough investigation and research,this is the first report that has proposed Fe-Mn-C ME for removing *** provides a novel approach and technological support for removing Sb(V)efficiently.

禽腺病毒血清4型(FAdV-4)是引起禽肝炎-心包积液综合征的重要病原,严重危害我国养禽业的发展。研究表明,FAdV-4六邻体(Hexon)蛋白是决定病毒毒力和致病性的重要因素之一。为了进一步探究Hexon蛋白在FAdV-4感染中的重要作用,本试验以鸡肝癌细胞(LMH)为研究模型,利用转录组测序技术对外源表达Hexon所诱导的差异表达基因进行筛选。结果显示,与对照组相比,外源表达Hexon试验组共筛选到445个差异基因表达上调,36个差异基因表达下调。其中,BAG3、JUN、IL8L1、CCL4和THBS1等基因之前已被报道与FAdV-4感染相关,但HSPB9、HSP90AA1、HSPA8、HSPA2、DCN、ELOVL3和SBK2等基因在FAdV-4感染中的作用还未被揭示。GO富集分析结果显示,下调的差异基因主要与早期内体和蛋白酶体附属复合体相关,而上调的差异基因主要与质膜、细胞外表面区域和超分子纤维相关。KEGG通路富集分析结果显示,差异表达基因主要富集在MAPK、Wnt和VEGF等信号通路。此外,通过蛋白质相互作用网络分析发现,HSP90AA1、HSPA8、JUN和DCN等多个关键蛋白位于整个网络中心且已被报道与多种病毒复制密切相关。综上所述,本研究通过转录组测序筛选出一系列由外源表达Hexon诱导的差异表达基因,为控制FAdV-4感染提供了新的靶点和理论依据。

刃板的磨损失效往往导致整个挖斗报废,为了提高其耐磨性能,采用等离子熔覆技术在刃板材料Q345B表面制备高钼高钒铁基耐磨涂层,研究熔覆电流(120、140、160 A)对涂层组织结构的影响,考察涂层的显微硬度、摩擦磨损与耐冲击性能。结果表明,电流大小对涂层的组织结构与界面状态影响较大,涂层组织主要由马氏体基体、弥散分布的细小球形碳化钒(VC)、多边形块状硼化钼(Mo_(2)B)和层片状复合硼碳化物(M_(2)(B,C))组成。120 A下制备的涂层与基材界面处存在局部未熔合区,增大电流导致涂层中VC的尺寸和分布间距变大,Mo_(2)B消失,M_(2)(B,C)增多且尺寸增大。涂层的平均显微硬度约为920 HV0.1,是耐磨钢NM400的2倍多,同等条件下的磨损失重仅为NM400的1/20,表现出优异的耐磨性能。带基材的涂层具有良好的耐冲击性能,且平行熔覆纹路的耐冲击性能优于垂直熔覆纹路的。
