| 1 | Ultra-thin metal-organic framework nanoribbons显示文摘Structure engineering of metal-organic frameworks(MOFs)at the nanometer scale is attracting increasing interest due to their unique properties and new functions that normally cannot be achieved in bulk MOF crystals.Here,we report the preparation of ultra-thin MOF nanoribbons(NRBs)by using metal-hydroxide nanostructures as the precursors.Importantly,this general method can be used to synthesize various kinds of ultra-thin MOF NRBs,such as MBDC(M=Co,Ni;BDC=1,4-benzenedicarboxylate),NiCoBDC,CoTCPP(TCPP=tetrakis(4-carboxyphenyl)porphyrin)and MIL-53(Al)NRBs.As a proof-of-concept application,the as-prepared ultra-thin Co BDC NRBs have been successfully used as a fluorescent sensing platform for DNA detection,which exhibited excellent sensitivity and selectivity.The present strategy might open an avenue to prepare MOF nanomaterials with new structures and unique properties for various promising applications. | Bingqing Wang Meiting Zhao Liuxiao Li Ying Huang Xiao Zhang Chong Guo Zhicheng Zhang Hongfei Cheng Wenxian Liu Jing Shang Jing Jin Xiaoming Sun Junfeng Liu Hua Zhang | 2020 | National Science Review2020，7，1： | 1 |
| 2 | Coordinatively unsaturated single Co atoms immobilized on C_(2)N for efficient oxygen reduction reaction显示文摘Developing cost-effective and high-efficiency oxygen reduction reaction(ORR)catalysts is imperative for promoting the substantial progress of fuel cells and metal-air batteries.The coordination and geometric engineering of single-atom catalysts(SACs)occurred the promising approach to overcome the thermodynamics and kinetics problems in high-efficiency electrocatalysis.Herein,we rationally constructed atomically dispersed Co atoms on porous N-enriched graphene material C_(2)N(CoSA-C2N)for efficient oxygen reduction reaction(ORR).Systematic characterizations demonstrated the active sites for CoSA-C2N is as identified as coordinatively unsaturated Co-N_(2)moiety,which exhibits ORR intrinsic activity.Structurally,the porous N-enriched graphene framework in C_(2)N could effectively increase the accessibility to the active sites and promote mass transfer rate,contributing to improved ORR kinetics.Consequently,CoSA-C_(2)N exhibited superior ORR performance in both acidic and alkaline conditions as well as impressive long-term durability.The coordination and geometric engineering of SACs will provide a novel approach to advanced catalysts for energy related applications. | Wenjing Xu Yidong Sun Jiaqi Zhou Maoqi Cao Jun Luo Haili Mao Pengfei Hu Hongfei Gu Huazhang Zhai Huishan Shang Zhi Cai | 2023 | Nano Research2023，16，2： | 1 |

| 4 | Studies of antioxidant performance of amine additives in lubricating oil using 3D-QSAR显示文摘Available model of 3D-quantitative structure-activity relationship (3D-QSAR, the method of TopomerCoMFA) has been used to establish relationship between antioxidant performances of lubricating oil (trimethylolpropane trioleate, TMPTO) with 15 kinds of amine additives and its molecular structure. Correlation coefficient of the cross-validation (include internal q2 and external qpred 2 ) and conventional correlation coefficient showed the model to be both stable and good predictive. The electron-donating group and larger steric effects group are adopted at the para-position or meta-position of amido on the benzene ring, and suitably decreasing the branch chain near the para-position, these indicate that the antioxidant performance of amine additives can be enhanced. The results not only can help us understanding the rule of antioxidant performance, but also providing guidance(s) to predict antioxidant performance of existing amine additives and to design or modify new amine additives in lubricating oil. | ZHAN ShengPeng DUAN HaiTao HUA Meng XU HaiPing SHANG HongFei JIN YongLiang JIA Dan TU JieSong LI Jian | 2017 | Science China(Technological Sciences)2017，60，2： | 1 |
| 5 | Method for the measurement of triboelectric charge transfer at solid–liquid interface显示文摘Triboelectrification between a liquid and a solid is a common phenomenon in our daily life and industry.Triboelectric charges generated at liquid/solid interfaces have effects on energy harvesting,triboelectrification-based sensing,interfacial corrosion,wear,lubrication,etc.Knowing the amount of triboelectric charge transfer is very useful for studying the mechanism and controlling these phenomena,in which an accurate method is absolutely necessary to measure the triboelectric charge generated at the solid–liquid interface.Herein,we established a method for measuring the charge transfer between different solids and liquids.An equipment based on the Faraday cup measurement was developed,and the leakage ratio(r_(l))was quantified through simulation based on an electrostatic field model.Typical experiments were conducted to validate the reliability of the method.This work provides an effective method for charge measurement in triboelectrification research. | Qin CHEN Bingxue CHENG Tiancheng WANG Hongfei SHANG Tianmin SHAO | 2023 | Friction2023，11，8： | 0 |
