A safe haven of SARS-CoV-2 in the environment:Prevalence and potential transmission risks in the effluent,sludge,and biosolids

中国化学会第十四届全国生物无机化学学术会议

作者： Kaiqing Cui Kefan Zhang Lili Meng Tingting Liu 马晓明 Lin Yang School of Chemistry and Chemical engineering Henan Normal University

Living biosystems with abundant organic and highly organized intracellular environment have been optimized by natural selection for millions of years. Organisms can construct designed minerals with respective unique function for a range of purposes, which has drawn more and more attractions of chemists and materials scientists. Here we propose a novel strategy to synthesize hollow porous Au nanospheres with a narrow size distribution around 350 nm by assembly of nanoparticles with the guidance of the secretion of yeast cells economically, effectively and environmental-friendly. These carbon-gold hybrid nanospheres exhibit high catalytic efficiency and cycling performance in promoting the degradation of aromatic pollutants. Our research could provide a biomimetic strategy to construct nanomaterials with hierarchical structure.

爱尔兰非木质生物质原料生产生物质颗粒燃料的潜力

中国化学会第29届学术年会

作者： Qichun Zhang School of Materials Science and engineering Nanyang Technological University

In this talk, I will describe our new approach to detect an d image ROSs through i norganic-organic upconversion nanophosphors（Figure 1）. This t ype of probes can be used not onl y for ratiometric UCL monitoring of the generation of ROS/RSS in living cells, but also to identif y the risk in biosystems through ratiometric UCL imaging of tissue. To the best of our knowledge, this is the first exam ple of RSSor ROS detection by using ratiometric UCL probes. Significantly, these novel ratiometric UCL nanoprobe as well as new design concept based on inor ganic-organic integration will be helpful in further development of the next-generation imaging technique for ROS/RSS without background noise, remarkable light penetration depth, and no photo-bleaching, which enable us to better clarifies its physiological roles.

燃料价格日益上涨和气候变化的威胁必然需要清洁的、可再生的独立能源。本研究应用ArcGIS9.2软件建立一个GIS模型,分析了以爱尔兰境内非木质生物质(包括小麦、燕麦、大麦和油菜的秸秆,柳树和芒属植物)为原料生产生物质颗粒燃料的情况。供热与发电行业将使用清洁的碳中性非木质生物质原料替代当前使用的化石燃料。本研究旨在分析确定爱尔兰境内生物质原料的总面积(公顷)数,并计算出非木质生物质原料的潜在产量。结果表明:谷类作物秸秆是生产生物质颗粒燃料潜力最大的生物质资源。爱尔兰东南部、西南部和中东部生物质产量最大,在这些地区生产生物质颗粒燃料可能最为经济可行。在供热与发电行业用非木质生物质取代矿物燃料对减少CO2排放潜力巨大,其实可行。

为了研究翻堆频率对中药渣堆肥过程及其理化性质的影响,采用中试规模的条垛式堆肥系统,研究了中药渣堆肥过程中温度、全碳、全氮、全磷、全钾、C/N、pH、GI及表观特征变化和堆肥产品的质量特征。试验设6个处理,分别为:不翻堆(A1)、每5天翻一次(A2)、每10天翻一次(A3)、每15天翻一次(A4)、每20天翻一次(A5)、每25天翻一次(A6)。结果表明:高温(≥50℃)持续时间以A3最长,达44天;与A1相比,A4、A5和A6的全碳含量分别减少了0.35%、1.73%和1.61%;A2、A3、A4和A6的全氮含量分别减少了5.32%、8.40%、5.25%和1.44%;A2、A3、A4、A5和A6的全磷含量且分别增加了4.82%、9.64%、6.83%、8.03%和2.01%;A2、A3、A4、A5和A6的全钾含量分别增加了6.18%、5.38%、2.96%、8.33%和4.03%;GI分别提高了35.15%、33.23%、31.30%、28.89%和17.01%,而C/N和pH差异不大。成熟中药渣中的C含量为36.0%,N含量比猪粪、鸡粪、羊粪、鸭粪及鹅粪分别高25.97%、17.12%、28.81%、41.20%和41.91%。综合分析各影响因素后认为,在中试规模的条垛式堆肥系统中进行中药渣堆肥时,以每10天翻堆一次较为适宜。

本研究调查了光照强度对海藻菌株Chlorellakessleri和Chlorellaprotothecoide养殖过程中生物质生长累积,去除城市污水养分及制备生物柴油的影响。研究采用的光照强度为0,15,30,60,120,200μmol·m-2·S-1。结果表明光照强度对两种海藻累积生物质,去除城市污水养分及制备生物柴油有显著影响,并且不同海藻菌株对光照强度的依赖性不同。对于海藻Chlorellakessleri测试的所有反应(除COD去除外),最佳光照强度是120μmol·m-2·S-1。对于海藻Chlorellaprotothecoide测试的所有反应,最佳光照强度是30μmol·m-2·S-1。海藻生物质中产生的生物柴油主要成分是16碳和18碳脂肪酸甲酯,海藻Chlorellakessleri和Chlorellaprotothecoide中最高的生物柴油含量分别为其干重的24.19%和19.48%。两个海藻品种在所有光照条件下都能高效去除废水中的养分。
