1Microwave-assisted synthesis of photoluminescent glutathione-capped Au/Ag nanoclusters: A unique sensor-on-a-nanoparticle for metal ions, anions, and small molecules显示文摘Even though great advances have been achieved in the synthesis of luminescent metal nanoclusters, it is still challenging to develop metal nanoclusters with high quantum efficiency as well as multiple sensing functionalities. Here, we demonstrate the rapid preparation of glutathione-capped Au/Ag nanoclusters (GS-Au/Ag NCs) using microwave irradiation and their unique sensing capacities. Compared to bare GS-Au NCs, the doped Au/Ag NCs possess an enhanced quantum yield (7.8% compared to 2.2% for GS-Au NCs). Several characterization techniques were used to elucidate the atomic composition, particulate character, and electronic structure of the fabricated NCs. According to the X-ray photoelectron spectroscopy (XPS) and X-ray absorption near-edge structure (XANES) spectra, a significant amount of Au exists in the oxidized state as Au(I), and the Ag atoms are positively charged. In contrast to those nanoclusters that detect only one analyte, the GS-Au/Ag NCs can be used as a versatile sensor for metal ions, anions, and small molecules. In this manner, the NCs can be regarded as a unique sensor-on-a-nanoparticle.Jia Zhang Yue Yuan Yu Wang Fanfei Sun Gaolin Liang Zheng Jiang Shu-Hong Yu 2015Nano Research2015,8,7:6
2Anti-vapor-penetration and condensate microdrop self-transport of superhydrophobic oblique nanowire surface under high subcooling显示文摘It is well-known that microscale gaps or defects are ubiquitous and can be penetrated by vapor,resulting in the failure of superhydrophobic effect and undesired condensate flooding under high subcooling.Here,we propose and demonstrate that such problem can be solved by the oblique arrangement of nanowires.Such a structure has been demonstrated to own anti-vapor-penetration and microdrop self-transport functions under high subcooling,unaffected by the microscale gaps.This is because vapor molecules can be intercepted by oblique nanowires and preferentially nucleate at near-surface locations,avoiding the penetration of vapor into the microscale gaps.As-formed microdrops can suspend upon the nanowires and have low solid-liquid adhesion.Besides,oblique nanowires can generate asymmetric surface tension and microdrop coalescence can release driving energy,both of which facilitate the microdrop self-removal via sweeping and jumping ways.This new design idea helps develop more advanced condensation mass and heat transfer interfaces.Rui Wang Feifei Wu Fanfei Yu Jie Zhu Xuefeng Gao Lei Jiang 2021Nano Research2021,14,5:1

4Application Effect of Sludge Extract in the Planting of Zinnia elegans显示文摘[Objectives] The research aimed to study the effect of sludge extract on the growth of Zinnia elegans, and evaluate its possibility of application. [Methods] Z. elegans was taken as research object, and the effect of sludge extract on the growth indicators of Z. elegans was studied. [Results] The sludge extract can obviously promote the growth of Z. elegans, and the growth indicators were significantly improved when compared with the control group. The application effect was close to that of foliar fertilizer purchased in the market. In each treatment group, the low concentration of sludge extract did not significantly promote the growth of Z. elegans, while too high concentration could inhibit its growth, and the optimal dilution ratio was 600 times. [Conclusions] Further preparation of amino acid foliar fertilizer from sludge extract and its application in planting garden plants can realize the resource utilization of sludge and has a good development and application prospect.Yu FU Cheng YANG Lifang CUI Fanfei MENG Aiai YANG Guangneng ZENG 2022Asian Agricultural Research2022,14,9:0
5Durable Super-repellent Surfaces: From Solid−Liquid Interaction to Applications显示文摘CONSPECTUS:A super-repellent surface is a type of liquid-repellency material that allows for various liquid drops to bead up,roll off,or even bounce back.Known for its ability to remain dry,perform self-cleaning,and have a low adhesion,a super-repellent surface presents great advantages in a number of applications.These include antifogging,anti-icing,oil/water separation,and fluid drag reduction.To fend off the liquids or drops,super-repellent surfaces combine the merits of surface chemistry and physical structure.By taking advantage of a low surface energy to prevent liquid from spreading,the super-repellent surfaces utilize the micronano structure to provide a framework that confines the solid−liquid interactions.Compared to beading up the drop of water,the repellence of liquid with low surface tension requires the subtle design of surface structure to resist the wetting of liquids.However,the inherent instabilities of the fragile micronano structure of super-repellent surfaces and solid−liquid interactions further make the fabrication of super-repellent surfaces complex to withstand dynamic environments(friction or wear)during application.In addition,the transparency and thermal stability of super-repellent surfaces are also the restrictive factors in some special application scenarios.To solve these challenges,durable super-repellent surfaces that can repel various liquids,possess robust mechanical and thermal stability,and show high transparency have been explored extensively in recent years.Fanfei Yu Dehui Wang Jinlong Yang Wenluan Zhang Xu Deng 2021Accounts of Materials Research2021,2,10:0
6Characterization of CoMn catalyst by in situ X-ray absorption spectroscopy and wavelet analysis for Fischer–Tropsch to olefins reaction显示文摘Cobalt carbide has recently been reported to catalyse the FTO con version of syngas with high selectivity for the production of lower olefins (C2-C4). Clarifying the formation process and atomic structure of cobalt carbide will help understand the catalytic mechanism of FTO. Herein, hydrogenati on of carb on monoxide was investigated for cobalt carbide synthesized from CoMn catalyst, followed by X-ray diffraction, transmission electron microscopy, temperature programmed reaction and in situ X-ray absorption spectroscopy. By monitoring the evolution of cobalt carbide during syngas conversion, the wavelet transform results give evidenee for the formation of the cobalt carbide and clearly demonstrate that the active site of catalysis was cobalt carbide.Ruoou Yang Zhaoming Xia Ziang Zhao Fanfei Sun Xianlong Du Haisheng Yu Songqi Gu Liangshu Zhong Jingtai Zhao Yunjie Ding Zheng Jiang 2019Journal of Energy Chemistry2019,28,5:0
