| 1 | Thiolactone copolymer donor gifts organic solar cells a 16.72% efficiency显示文摘Since 1995,bulk-heterojunction organic solar cells consisting of one or two organic donors and one or two organic acceptors have been fighting for high power conversion efficiencies(PCEs)and good stability[1].Until recent years,this next-generation photovoltaic technology starts to offer decent PCEs,shedding the light on commercialization,and attracting great attention again[2-14].Compared w让h the continuously emerging highperformance nonfullerene acceptors,high-performance donors are rare. | Ji Xiong Ke Jin Yufan Jiang Jianqiang Qin Tan Wang Jinfeng Liu Qishi Liu Haili Peng Xiongfeng Li Anxin Sun Xianyi Meng Lixiu Zhang Ling Liu Wenting Li Zhimin Fang Xue Jia Zuo Xiao Yaqing Feng Xiaotao Zhang Kuan Sun Shangfeng Yang Shengwei Shi Liming Ding | 2019 | Science Bulletin2019，64，21： | 17 |
| 2 | APC在空分装置中的应用显示文摘张家港盈鼎气体有限公司二期空分装置采用经典的内压缩、全精馏无氢制氩流程,于2017年12月投产。该套空分装置原始设计没有考虑APC控制,经过约3 a的运行考核与调研,于2021年4月立项由盈德气体(上海)有限公司和上海福克斯波罗有限公司共同实施APC项目——首先采用APC理论方法在DCS层面实施PID结构和参数优化,然后基于AVEVA APC软件平台,经过阶跃测试、建模、控制器搭建、APC-DCS界面创建、APC投运调试等环节,成功实现了多个重要CV (被控变量)的稳定控制及卡边优化。2021年12月16日APC系统投运后,空分装置的智能化控制程度及能源利用率明显提升,氩与氧气的提取率上升,经济效益非常可观,并实现了空分装置的自动变负荷操作,同时减轻了操作人员的工作量、降低了人为操作中的风险因素。 | 何伟 周兵 赵向远 FENG XIONGFENG 程向龙 | 2022 | 中氮肥2022，，5： | 2 |
| 3 | the National Natural Science Foundation of China(41877029,41961130383);Royal SocietyNewton Advanced Fellowship(NAF\R1\191017);Wuhan Science and Technology Bureau(2019020701011469).显示文摘Due to the tremendous diversity of microbial organisms in topsoil,the estimation of saturated richness in a belowground ecosystem is still challenging.Here,we intensively surveyed the 16S rRNA gene in four 1 m2 sampling quadrats in a typical grassland,with 141 biological or technical replicates generating over 11 million sequences per quadrat.Through these massive data sets and using both non-asymptotic extrapolation and non-parametric asymptotic approaches,results revealed that roughly 15919±193,27193±1076 and 56985±2347 prokaryotic species inhabited in 1 m2 topsoil,classifying by DADA2,UPARSE(97%cutoff)and Deblur,respectively,and suggested a huge difference among these clustering tools.Nearly 500000 sequences were required to catch 50%species in 1 m2,while any estimator based on 500000 sequences would still lose about a third of total richness.Insufficient sequencing depth will greatly underestimate both observed and estimated richness.At least~911000,~3461000,and~1878000 sequences were needed for DADA2,UPARSE,and Deblur,respectively,to catch 80%species in 1 m2 topsoil,and the numbers of sequences would be nearly twice to three times on this basis to cover 90%richness.In contrast,α-diversity indexes characterized by higher order of Hill numbers,including Shannon entropy and inverse Simpson index,reached saturation with fewer than 100000 sequences,suggesting sequencing depth could be varied greatly when focusing on exploring differentα-diversity characteristics of a microbial community.Our findings were fundamental for microbial studies that provided benchmarks for the extending surveys in large scales of terrestrial ecosystems. | Shuzhen Li Xiongfeng Du Kai Feng Yueni Wu Qing He Zhujun Wang Yangying Liu Danrui Wang Xi Peng Zhaojing Zhang Arthur Escalas Yuanyuan Qu Ye Deng | 2022 | Soil Ecology Letters2022，4，3： | 1 |
