1Method of Fault Area & Section Location for Non-solidly Earthed Distribution System显示文摘中国中压配电网以架空线为主,多为小电流系统,单相接地故障占到电网故障总数的80%以上,但中国配网自动化系统基本上没有小电流接地故障定位功能,使配网自动化系统在提高可靠性的作用上大打折扣。给出一种小电流接地故障区段定位新方法,在线路上配置广域相量测量固定测点,获取小电流电网单相接地故障特征信息。基于测点相邻矩阵区段起始测点标识向量和故障路径标识向量概念,提出确定故障区间边界节点算法。物理模拟实验和挂网测试表明:该故障分区分段定位方法能够在线求解小电流接地故障段边界节点,缩小线路维护巡视范围。确定故障区间边界节点算法还可用于确定故障区相关负荷开关,为线路维护和馈线自动化提供依据。ZHENG Guping JIANG Chao LI Gang QI Zheng YANG Yihan 2012中国电机工程学报2012,32,13:28
2Zeolitic Imidazolate Framework 8-Derived Au@ZnO for Efficient and Robust Photocatalytic Degradation of Tetracycline显示文摘Summary of main observation and conclusion Tetracycline (TC) and other antibiotics accumulated in groundwater and soil pollute ecological environment and threaten human health. Gold nan oparticles doped on photocatalysts are able to enhance the photodegradation efficiency during removing these antibiotics, but preparation of Au nanoparticles of well-dispersion on photocatalysts remains challenging. In this work, zeolite imidazolate (ZIF-8) was employed as the precursor to prepare Au@ZnO photocatalyst via impregnation and in-situ reduction method to efficiently degrade the tetracycline in the aqueous solution. Au nanoparticles are of 10 nm in size and uniformly dispersed on the surfaces of ZnO microstructures. The as-prepared Au@ZnO is able to remove 85.5% of TC of 0.010 mg/mL within 2h, presenting higher photocatalytic activity than pure ZnO catalyst. Most importantly, the catalyst shows its superior stability after five cycles without structure and activity changing. The mechanism of the photocatalytic degradation was discussed in detail.Bijun Gao Jin Zhou Hongliang Wang Guping Zhang Jinghui He Qingfeng Xu Najun Li Dongyun Chen Hua Li Jianmei Lu 2019Chinese Journal of Chemistry2019,37,2:6
3流化床干燥红茶的特性显示文摘阐述了流化床干燥CTC和Freedom红茶的干燥特性以及干燥温度对产品平均尺寸的影响.试验表明,干燥过程可以分为2个阶段,即第1干燥阶段和第2干燥阶段.在第1干燥阶段排气温度保持不变,而在第2干燥阶段排气温度逐渐升高.提高干燥温度有利于CTC红茶干燥强度以及排气相对湿度的提高;提高干燥温度难以使Freedom红茶的干燥强度大幅度提高,却使排气相对湿度降低.提高干燥温度可以增大CTC红茶产品的平均粒度,但不影响Freedom红茶产品的平均粒度.宋洪波 毛志怀 GUPING Lian 2004福建农林大学学报(自然科学版)2004,33,4:3
4A mini-review on ZnIn_(2)S_(4)-Based photocatalysts for energy and environmental application显示文摘As one of the most attractive and eco-friendly technologies,semiconductor photocatalysis is demonstrated as a potential strategy to solve global energy shortage environmental pollution problems.Regarding semiconductor-based photocatalysts,Zinc indium sulfide(ZnIn_(2)S_(4)) with various morphological structures has become research hotspots owing to its superior visible light absorption,high chemical durability and low cost.Nevertheless,the photocatalytic activity of pristine ZnIn_(2)S_(4) is unsatisfactory due to limited range of visible light absorption and fast recombination rate of light-induced electrons and holes.Different modification strategies,such as metal deposition,element doping,vacancy engineering and semiconductor combination,have been systematically developed for enhancing the photocatalytic performance of ZnIn_(2)S_(4) materials.In order to promote further developments of ZnIn_(2)S_(4) in photocatalytic applications,this mini-review summarizes the progress of recent research works for the construction of highly activity ZnIn_(2)S_(4)-based photocatalysts for the first time.In addition,the typical applications of ZnIn_(2)S_(4)-based photocatalytic materials have been critically reviewed and described such as in hydrogen evolution from photocatalytic water splitting,carbon dioxide photoreduction,and treatment of water pollution.The current challenges and further prospects for the development of ZnIn_(2)S_(4) semiconductor photocatalysts are finally pointed out.Guping Zhang Hao Wu Dongyun Chen Najun Li Qingfeng Xu Hua Li Jinghui He Jianmei Lu 2022Green Energy & Environment2022,7,2:2
5A supramolecular co-delivery strategy for combined breast cancer treatment and metastasis prevention显示文摘We herein propose a co-delivery approach where small interference RNA(siRNA)and anticancer chemotherapeutic drug are simultaneously loaded into a single delivery carrier for the combined treatment of breast cancer and metastasis prevention.The co-delivery vector is composed of chondroitin sulfate(CS)-coatedβ-cyclodextrin-polyethylenemine polymer,which is capable of loading paclitaxel(PTX)and siRNA simultaneously to form therapeutic nanocomplexes.The nanocomplex,termed as CPPTX-siCD146-CS,is demonstrated to have strong active targeting ability towards CD44-overexpresing breast cancer cells.Moreover,the co-delivery of PTX and siRNA not only effectively inhibits cancer cells proliferation and induces apoptosis,but also well prevents metastasis.Importantly,CP-PTX-siCD146-CS nanocomplexes exhibit stronger cytotoxic effects and anti-metastatic effects on MBA-MD-231 breast cancer cells,in comparison with PTX or siCD146 mono-treatment.The current study defines a potential therapeutic strategy for the combined breast cancer treatment and metastasis prevention from a codelivery perspective.Yuxuan Chen Bowen Li Xiaohong Chen Min Wu Yongtao Ji Guping Tang Yuan Ping 2020Chinese Chemical Letters2020,31,5:1

152D/2D hierarchical Co_(3)O_(4)/ZnIn_(2)S_(4)heterojunction with robust builtin electric field for efficient photocatalytic hydrogen evolution显示文摘Because of its importance in enhancing charge separation and transfer,built-in electric field engineering has been acknowledged as an effective technique for improving photocatalytic performance.Herein,a stable p–n heterojunction of 2D/2D(2D:twodimensional)Co_(3)O_(4)/ZnIn_(2)S_(4)with a strong built-in electric field is precisely constructed.The Co_(3)O_(4)/ZnIn_(2)S_(4)heterojunction exhibits a higher visible-light photocatalytic hydrogen(H2)evolution rate than the individual components,which is primarily attributed to the synergy effect of improved light absorption,abundant active sites,short charge transport distance,high separation efficiency of photogenerated carriers.Furthermore,the photoelectrochemical studies and density functional theory(DFT)calculation results demonstrate that the enhanced interfacial charge separation and migration induced by the generated built-in electric field are the critical reasons for the boosted photocatalytic performance.This research might pave the way for the rational design and manufacturing of 2D/2D heterojunction photocatalysts with extremely efficient photocatalytic performance for solar energy conversion.Guping Zhang Xunxun Li Mengmeng Wang Xueqing Li Yaru Wang Shuting Huang Dongyun Chen Najun Li Qingfeng Xu Hua Li Jianmei Lu 2023Nano Research2023,16,5:0
