Developing chemotherapy drugs with high efficacy and few side effects has been a bottleneck problem that requires an efficient solution.The active cancer treatment ingredient disulfiram(DSF),inspired by the copper(Ⅱ)diethyldithiocarbamate complex(CuET),ca
WO3(H2O)0.333/CdS(WS)nanocomposites are obtained via a rapid micro-wave hydrothermal method,and they are served as visible light-driven photocatalysts for the H2 generation.By using Pt as the cocatalyst,the WS nanocomposite with 70 wt.％CdS reaches the H2
Interface engineering is an efficient strategy to modify electronic structure and further improve electrocatalytic activity.Herein,crystalline/amorphous heterostruc-tured Co3O4-SmMn2O5 nanosheets(Co3O4-SMO NSs)have been synthesized by coupling of SMO(elec
按照新时代防汛抗旱工作要求,辽宁省经过优化调整,基本形成了新的防汛抗旱指挥体系,责任体系、制度体系、监测预警体系、抢险救援体系、技术支撑体系等方面不断完善,并经过2019年、2020年防汛抗旱工作实践检验,实现了“不死少伤少损失”的防汛抗旱工作目标.针对防汛抗旱实践中,工程体系、非工程体系、指挥体系、基层防办能力、技术支撑体系等方面存在的问题进行了思考与探讨,并提出下一步对策和工作举措.
Nanotoxicology has become the subject of intense research for more than two decades.Thousands of articles have been published but the space in understanding the nanotoxicity mechanism and the assessment is still unclear.Recent researches clearly show pote
We prepared porous Fe-doped nickel cobaltate(Fe-NiCo2O4)hollow hierarchical nanospheres through a facile self-templated synthetic strategy.Due to the porous hollow structure and composition,the Fe-NiCo2O4 presented vastly superior electrocatalytic activit
Water-solid triboelectric nanogenerators(TENGs),as new energy collec-tion devices,have attracted increasing attention in ocean energy harvesting and self-powered sensing.Polyacrylic acid(PAA)coating,usually used on the surface of marine equipment,has the
To construct supercapacitors(SCs)with high-efficient electrochemical properties,the morphology and structure of applied electrode materials are the key factors.Herein,three-dimensional(3D)sea urchin-like MnCo2O4 nanoarchitectures grown on Ni foam(NF)were
Solar thermal desalination(STD)is a promising and sustainable techno-logy for extracting clean water resources.Whereas recent studies to improve STD performance primarily focus on interfacial solar evaporation,a non-traditional bottom heating method was d
各个国家(或地区)在引航管理上具有不同的机构运作、组织架构、管理方式,见表1.引航具有很强、明显的公益性,关系到国家港口的安全和综合竞争力,具有保障公共安全和提供公共服务性的特点,从服务的非竞争性、非排他性以及是否产生外部效益来看,引航不以营利为目的,具有准公共物品的属性,不是完全由市场配置资源的.大多数国家或地区一个港口设置一家引航机构,完全市场化的模式较少;引航机构的法人性质有政府、企业和民间组织,引航员的身份有公务员、企业员工和自由职业者等3种,但运行机制比较类似,即采用类似政府特许经营的模式,给予
