作者： Zhiqing Liang Ziqiu ren Ziyu Wang Nan Yan ling Li Bo Zhang Yanlin Song College of Chemistry Zhengzhou UniversityZhengzhou 450052China Key Laboratory of Applied Surface and Colloid Chemistry Ministry of Education Shaanxi Key Laboratory for Advanced Energy DevicesShaanxi Engineering Lab for Advanced Energy Technology School of Materials Science and EngineeringShaanxi Normal UniversityXi’an 710119China Key Laboratory of Green Printing Institute of ChemistryChinese Academy of Sciences(ICCAS)Beijing Engineering Research Center of Nanomaterials for Green Printing TechnologyNational Laboratory for Molecular Sciences(BNLMS)Beijing 100190China

In inverted perovskite solar cells (PSCs),effective modification of the interface between the metalcathode and electron transport layer (ETL) is crucial forachieving high performance and stability. Herein, sulfonatedbathocuproine, commonly known as disodium bathocuproinedisulfonate (BCDS), was employed as a cathode buffer layerto address the interfacial issues at the [6,6]-phenyl-C61-butyricacid methyl ester (PCBM)/Ag interface. BCDS possesses theability to form coordinate bonds with Ag electrodes. Theutilization of the BCDS buffer layer enhanced the chargeextraction capability at the cathode interface whilesimultaneously achieving interfacial defect passivation,improving interfacial contact and increasing the built-in electricfield. Consequently, a power conversion efficiency (PCE) of25.06% was achieved. Furthermore, owing to the excellent filmforminguniformity of BCDS on PCBM, the stability of thedevice was also improved. After storage in dry air for morethan 2000 h, the device maintained 96% of its initial efficiency. This work underscores the remarkable potential of tailoringcoordination groups to enhance charge extraction efficiency at the ETL-cathode interface, unveiling a promising newfrontier in buffer layer development and performance optimization strategies for PSCs.

Bio-functional Design for Metal Implants,a New Concept for Development of Metallic Biomaterials

引用

Journal of Materials Science & Technology 2013年第11期29卷 1005-1010页

作者： ling ren Ke Yang Institute of Metal Research Chinese Academy of Sciences

A new concept for development of metallic biomaterials is proposed in this article, i.e., a certain bio-function can be realized for a metal implant through continuous release of a designed bio-functional metal element from surface of the metal implant in the body environment. This creative idea has been verified to be possible by several different in vitro and in vivo experimental evidences on the Cu-bearing stainless steels and magnesium based metals. It was indicated that a trace amount of Cu release from the Cu-bearing steels could have obvious bio-functions of reduction of the in-stent restenosis （ISR）, anti-bacterial infection, inhibiting the inflammatory cells and even promoting the early osteogenesis. Furthermore, the degradation of magnesium based metals in bones could promote the new bone formation, enhance the bone mineral density for the osteoporosis modeled animal, and even have strong anti-bacterial ability and strong cytotoxicity to bone tumor cells due to the enhancement of pH. Special bio-function with satisfied load-bearing capacity for metallic biomaterials will bring higher application values for the implant made of this novel material. This is an attractive direction for research and development with many challenges, but the final success will be much beneficial to the majority of patients.

We report a novel self-powered nanocomposite sensor composed of Ko.5Nao.5NbO3 （KNN） nanoparticles （NPs） and multiwalled carbon nanotubes （MW-CNTs）. The KNN NPs and MW-CNTs are dispersed in polydimethylsioxane by mechanical agitation to produce a piezoelectric nanocomposite device. The device exhibits an output voltage of approximately 30 V and output current of approximately 15 μA. Furthermore, the device exhibits potential as a self-powered pressure sensor because the output voltage can be tested to detect the pressure applied to the device and does not require other sources.
