| 2 | A new method for optimal FTU placement in distribution network under consideration of power service reliability显示文摘Modern distribution network with high penetration of intermittent renewable sources and the so-called prosumers requires more reliable distribution automation(DA) system for safe operation and control. The design of optimal feeder terminal units(FTU)placement is critical and economical for the effective DA application. Previously proposed solutions of optimal FTU placement aiming to ensure the accuracy of state estimation(SE), typically include the following two main shortcomings: 1) only to obtain the optimal FTU placement in quantity, and the analysis of FTU location is not considered yet; 2) few consider the uncertainty of intermittent power injections in the analysis of state estimation. In this paper, a modified methodology of FTU placement is proposed not only aiming to ensure the accuracy of state estimation with the minimum number of meters, but also finding those specific FTU locations to guarantee the power service reliability. Moreover, the uncertainty models of those intermittent power injections are also considered by using probability density function(PDF). The resultant optimization problem is addressed by using the covariance matrix adaptation evolution strategy(CMA-ES). Case studies demonstrate the feasibility and effectiveness of the proposed methodology. | XU JunJun WU ZaiJun YU XingHuo HU QinRan ZHU ChengZhi DOU XiaoBo GU Wei WU Zhi | 2017 | Science China(Technological Sciences)2017，60，12： | 3 |
| 3 | Biocompatible, small-sized and well-dispersed gold nanoparticles regulated by silk fibroin fiber from Bombyx mori cocoons显示文摘Biocompatible, small-sized but well-dispersed gold nanoparticles (Au NPs) remain a major challenge for their synthesis. Here a convenient solution impregnation technique is developed to prepare such Au NPs under the regulation of degummed silk fibroin fibers (SFFs) extracted from Bombyx mori cocoons. SFFs play multiple roles in the formation of Au NPs such as reactive substrate to capture AuCl4^- ions by the chelation of -C = 0, reducing agent for Au(0) by the reduction of -OH , and modifiers to render biocompatible Au NPs by some functional groups and biomolecules. The as-prepared Au NPs with a size of 7-10 nm are embedded in the solid SFF substrate, and can disperse well in the liquid system by the disintegration of SFFs into silk fibroin (SF) in a certain CaCl2 solution. The biocompatible Au NPs exhibit uniform small size and distribute stably in both solid and solution states, which have distinctive properties and functional advantages, and bring great convenience to their storage and transportation. | Chengzhi YANG Shikun CHEN Huilan SU Haoyue ZHANG Jianfei TANG Cuiping GUO Fang SONG Wang ZHANG Jiajun GU Qinglei LIU | 2019 | Frontiers of Materials Science2019，13，2： | 2 |
| 4 | Genome-wide signatures of the geographic expansion and breeding of soybean显示文摘Soybean is a leguminous crop that provides oil and protein. Exploring the genomic signatures of soybean evolution is crucial for breeding varieties with improved adaptability to environmental extremes. We analyzed the genome sequences of 2,214 soybeans and proposed a soybean evolutionary route, i.e., the expansion of annual wild soybean(Glycine soja Sieb. & Zucc.) from southern China and its domestication in central China, followed by the expansion and local breeding selection of its landraces(G. max(L.) Merr.). We observed that the genetic introgression in soybean landraces was mostly derived from sympatric rather than allopatric wild populations during the geographic expansion. Soybean expansion and breeding were accompanied by the positive selection of flowering time genes, including GmSPA3c. Our study sheds light on the evolutionary history of soybean and provides valuable genetic resources for its future breeding. | Ying-Hui Li Chao Qin Li Wang Chengzhi Jiao Huilong Hong Yu Tian Yanfei Li Guangnan Xing Jun Wang Yongzhe Gu Xingpeng Gao Delin Li Hongyu Li Zhangxiong Liu Xin Jing Beibei Feng Tao Zhao Rongxia Guan Yong Guo Jun Liu Zhe Yan Lijuan Zhang Tianli Ge Xiangkong Li Xiaobo Wang Hongmei Qiu Wanhai Zhang Xiaoyan Luan Yingpeng Han Dezhi Han Ruzhen Chang Yalong Guo Jochen C.Reif Scott A.Jackson Bin Liu Shilin Tian Li-juan Qiu | 2023 | Science China(Life Sciences)2023，66，2： | 1 |
| 5 | Optimal Operation of Micro-energy Grids Considering Shared Energy Storage Systems and Balanced Profit Allocations显示文摘Following the unprecedented generation of renewable energy,Energy Storage Systems(ESSs)have become essential for facilitating renewable consumption and maintaining reliability in energy networks.However,providing an individual ESS to a single customer is still a luxury.Thus,this paper aims to investigate whether the Shared-ESS can assist energy savings for multiple users through Peer-to-Peer(P2P)trading.Moreover,with the increasing number of market participants in the integrated energy system(IES),a benefit allocation scheme is necessary,ensuring reasonable benefits for every user in the network.Using the multiplayer cooperative game model,the nucleolus and the Shapley value methods are adopted to evaluate the benefit allocation between multiple users.Numerical analyses based on multiple micro-energy grids are performed,so as to assess the performance of the Shared-ESS and the proposed benefit allocation scheme.The results show that the micro-energy grid cluster can save as much as 38.15%of the total energy cost with Shared-ESS being equipped.The following conclusions can be drawn:the Shared-ESS can significantly reduce the operating costs of the micro-energy grid operator,promote the consumption of renewable energy,and play the role of peak-shaving and valley-filling during different energy usage periods.In addition,it is reflected that the multiplayer cooperative game model is effective in revealing the interaction between the micro-energy grids,which makes the distribution results more reasonable. | Hanlin Zhang Suyang Zhou Wei Gu Chengzhi Zhu X.G.Chen | 2023 | CSEE Journal of Power and Energy Systems2023，9，1： | 1 |

| 7 | Pumping and sliding of droplets steered by a hydrogel pattern for atmospheric water harvesting显示文摘Atmospheric water harvesting is an emerging strategy for decentralized and potable water supplies.However,water nucleation and microdroplet coalescence on condensing surfaces often result in surface flooding owing to the lack of a sufficient directional driving force for shedding.Herein,inspired by the fascinating properties of lizards and catfish,we present a condensing surface with engineered hydrogel patterns that enable rapid and sustainable water harvesting through the directional pumping and drag-reduced sliding of water droplets.The movement of microscale condensed droplets is synergistically driven by the surface energy gradient and difference in Laplace pressure induced by the arch hydrogel patterns.Meanwhile,the superhydrophilic hydrogel surface can strongly bond inner-layer water molecules to form a lubricant film that reduces drag and facilitates the sliding of droplets off the condensing surface.Thus,this strategy is promising for various water purification techniques based on liquid-vapor phase-change processes. | Wei Zhang Qinghua Ji Gong Zhang Zhenao Gu Haozhi Wang Chengzhi Hu Huijuan Liu Zhiyong Jason Ren Jiuhui Qu | 2023 | National Science Review2023，10，12： | 0 |
| 8 | Intermolecular through-space charge transfer enabled by bicomponent assembly for ultrasensitive detection of synthetic cannabinoid JWH-018显示文摘Launching the intermolecular through-space charge transfer(TSCT)from a bicomponent assembly for photophysical property manipulation is of great significance in fluorescence probe design.Here,we demonstrate the elaborate control of droplet evaporation dynamics for intermolecular TSCT can facilitate the ultrasensitive detection of JWH-018,a representative synthetic cannabinoid.Driven by diverse intermolecular interactions,the probe,and JWH-018 assemble in a closely stacked manner to emit strong fluorescence at 477 nm,ascribing to the intermolecular TSCT at the S2 state.The strategy realizes an ultra-low limit of detection of 11 nmol/mL and great selectivity towards JWH-018.The practicability is further verified by constructing a sensing chip for JWH-018 aerosol detection,which facilitates the on-site drug abuser screening with the naked eye.Moreover,the proposed assembly-enabled TSCT is expected to find a variety of applications for optoelectronic materials design and photophysical mechanism-dominated molecular recognition. | Chaogan Liu Fangfang Xiao Yushu Li Da Lei Yuan Liu Xiaowei Ma Chengzhi Gu Xincun Dou | 2023 | Aggregate2023，4，4： | 0 |
