| 1 | Bending-Induced Conductance Increase in Individual Semiconductor Nanowires and Nanobelts显示文摘Reliable ohmic contacts were established in order to study the strain sensitivity of nanowires and nanobelts.Significant conductance increases of up to 113%were observed on bending individual ZnO nanowires or CdS nanobelts.This bending strain-induced conductance enhancement was confirmed by a variety of bending measurements,such as using different manipulating tips(silicon,glass or tungsten)to bend the nanowires or nanobelts,and is explained by bending-induced effective tensile strain based on the principle of the piezoresistance effect. | Xiaobing Han Guangyin Jing Xinzheng Zhang Renmin Ma Xuefeng Song Jun Xu Zhimin Liao NingWang Dapeng Yu | 2009 | Nano Research2009，2，7： | 2 |
| 2 | Direct synthesis of high-quality perovskite nanocrystals on a flexible substrate and deterministic transfer显示文摘Solid-state perovskite nanocrystals are promising coherent light sources, as there is optical feedback within the crystal structure. In order to utilize the high performance of perovskites for on-chip applications, or observe new physical phenomena, these crystals must be integrated with pre-fabricated electronic or photonic structures. However, the material's fragility has made the deterministic transfer a great challenge thus far. Here, we report the first deterministic transfer of perovskite nanocrystals with sub-micron accuracy. Cesium lead halide(CsPbI_3) nanocrystals were directly synthesized on flexible polydimethylsiloxane(PDMS) stamps via chemical vapor deposition(CVD) and subsequently transferred onto arbitrary substrates/structures. We demonstrated the transfer of a CsPbI_3 crystalline nanoplate(NP)onto an 8 mm fiber core and achieved single-mode whispering gallery mode lasing. Our method can be extended to a variety of other arbitrary substrates(e.g., electrodes, photonic structures, micromechanical systems), laying the foundations for previously unattainable opportunities in perovskites-based devices. | Yilun Wang Xing Cheng Kai Yuan Yi Wan Pan Li Yuhao Deng Haoran Yu Xiaolong Xu Yi Zeng Wanjin Xu Yanping Li Renmin Ma Kenji Watanabe Takashi Taniguchi Yu Ye Lun Dai | 2018 | Science Bulletin2018，63，23： | 0 |
| 3 | Zeolite NaY-mediated oxidation of dyes with H_2O_2: unique heterogeneous non-transition metal center cleavage of H_2O_2 under visible light irradiation显示文摘This study investigated the visible-light catalysis mediated by zeolite NaY on the oxidation of dyes with H2O2. The results demonstrated that zeolite NaY acts as a sink for the electron from the photo-excited dye in the heterogeneous catalysis. Furthermore, the electron can effectively activate H2O2 to produce ?OH radical that is a powerful oxidant for the oxidation of dye at room temperature. The effects of the framework topology, Si/Al ratio, and exchangeable cation of the zeolite on the oxidation of various dyes were also shown. | LIU LiLi1, MA WanHong1, SONG WenJing1, CHEN ChunCheng1, LIN Jun2, ZHAO JinCai1, QIAN XinHua3 & ZHANG ShiBo3 1 Institute of Chemistry, Chinese Academy of Sciences, Beijing 100080, China 2 Department of Chemistry, Renmin University of China, Beijing 100872, China 3 Fushun Petrochemical Company, PetroChina Company Limited, Fushun 113008, China | 2007 | Science China Chemistry2007，50，6： | 0 |
