Metal-organic frameworks(MOFs)are a class of hybrid materials with many promising applications.In recent years,lots of investigations have been oriented toward applications of MOFs in electronic and photoelectronic devices.While many high-quality reviews have focused on synthesis and mechanisms of electrically conductive MOFs,few of them focus on their photophysical properties.Herein,we provide an in-depth review on photoconductive and photoluminescent properties of conductive MOFs together with their corresponding applications in solar cells,luminescent sensing,light emitting,and so forth.For integration of MOFs with practical devices,recent advances in fabrication of photoactive MOF thin films are also summarized.

Metal-organic frameworks(MOFs)have been intensely studied for the past few decades as an enormous family of highly tunable porous materials with promisingly applicable functionalities in adsorption,separation,catalysis,sensing,electrochemistry,and a great number of emerging purposes.As a classic MOF,zeolitic imidazolate framework-8(ZIF-8)is conventionally one of the very few MOF members that has been commercialized with considerable production.

Plasma Science and Technology 2024年第1期26卷 50-61页

Plasma-activated water(PAW),as an extended form of cold atmospheric-pressure plasma,greatly expands the application of plasma-based technology.The biological effects of PAW are closely related to the aqueous reactive species,which can be regulated by the activation process.In this study,surface plasma-activated air(SAA)and a He+O_(2)plasma jet(Jet)were parallelly combined(the SAA+Jet combination)or sequentially combined(the SAA→Jet combination and the Jet→SAA combination)to prepare plasma-activated saline(PAS).The PAS activated by the combinations exhibited stronger bactericidal effects than that activated by the SAA or the Jet alone.The concentrations of H_(2)O_(2)and NO_(2)^(-)were higher in the PAS activated by the Jet→SAA combination,while ONOO^(-)concentrations were close in the three kinds of PAS and^(1)O_(2)concentrations were higher in the PAS activated by the SAA+Jet combination.The analysis of scavengers also demonstrated that H_(2)O_(2),^(1)O_(2),and ONOO^(-)in the PAS activated by the SAA+Jet combination,and^(1)O_(2)in the PAS activated by the Jet→SAA combination played critical roles in bactericidal effects.Further,the effective placement time of the three PAS varied,and the PAS activated by the Jet→SAA combination could also inactivate 2.6-log_(10)of MRSA cells after placement for more than 60 min.The regulation of reactive species in plasma-activated water via different combinations of plasma devices could improve the directional application of plasma-activated water in the biomedical field.

等离子体生物医学兴起20余年来,已有多项技术通过美国食品药品监督管理局(FDA)认证并推广应用,但现有的应用方式主要采用等离子体直接处理生命体,存在处理面积小、作用深度浅、有效时间短、稳定性不足等问题,限制了等离子体生物医学的适用范围和应用效果。为此,在近10年研究基础上,发展了等离子体活化介质技术,即:采用等离子体活化处理气体、液体或水凝胶等介质材料,将活性粒子加载到介质材料中再应用,使等离子体生物医学从直接处理变革到间接处理,推动实现“更大面积、更深部位、安全稳定、持续有效”的应用升级。该文总结了等离子体活化介质技术的形成背景与研究现状,分析该技术当前面临的关键科学和技术问题,给出最新研究结果并展望未来发展方向,以期为同行学者和研究生提供参考。

The surface micro-discharge(SMD)excited by pulsed voltage in open air is experimentally studied by measuring its voltage,current,emission image,emission spectrum,and ultraviolet(UV)absorption spectrum.It is found that the SMD occurs intermittently in each cycle,and that it consists of many filaments on the surface of grounded electrode.While the applied voltage’s peak value Up increases from 1.75 kV to 7.25 kV,the discharge area keeps expanding until Up≈6 kV,when the discharge occupies all the available area.The emission spectrum of nitrogen metastable N2(C-B)and the density of ozone increase almost linearly.The ozone density decreases hyperbolically downstream of the grounded electrode due to the diffusion in open air.The characteristics of pulsed SMD are presented and analyzed as well,which may be referred by further investigations.

作者： ZHONG Jiangwei liu dingxin LI Zhuo SUN Xiaowei Shanghai Institute of Microsystem and Information Technology Chinese Academy of Sciences State Key Laboratory of Metal Matrix Composites Shanghai Jiao Tong University Graduate University of Chinese Academy of Sciences Lenovo Research Shanghai Branch

A novel surface treatment method of plating Cu+PPS film/coating on a mobile phone’s stainless steel frame for improving the antenna system efficiencies is proposed. The mobile phone was measured in free space, in a silicon cover, and in the hand and cover simultaneously. It’s found that with this surface treatment, the total efficiency of the antenna system can be improved in all the four cases respectively by 14.22%,1.38%, 15.19% and 1.72% at 940 MHz(GSM900:880–960 MHz), 2.59%, 3.21%, 4.81% and 1.43% at 1720 MHz(DCS:1710–1880 MHz) and 6.34%, 2.85%, 9.83% and2.32% at 2100 MHz(WCDMA:1920–2170 MHz). This lowcost surface treatment method is an important breakthrough to improve antenna system performance of mobile phones especially for those with a stainless steel frame, and suitable for mass production.

建设师德高尚的高素质教师队伍是落实习近平总书记关于教师队伍系列指示精神的首要之义,是新时代加强高校教师队伍建设的根本遵循。高校教师师德非天然玉成,不仅取决于教师个体内化过程中的各种主动性因素,更与社会和高校是否建立起适宜师德生长的外在支撑体系密切相关。尤其在当下教师队伍师德素质参差不齐的情况下,高校教师的师德养成,既要打破过于偏重师德认知教育的传统模式,又要避免过于偏重行为规范约束的底线模式,聚焦教师师德素养提升这条主线,探索建立起以契合教育为基础、以制度规约为保障、以典型模范为引领、以舆论褒贬为支撑、以环境滋养为依托的外在协同发力综合机制。
