| 2 | The effect of dispersion of TiO_2 nanoparticles on preparation of flexible dye-sensitized photoanodes显示文摘Generally, nanoparticles are easy to aggregate due to their nano sizes, which influence the physical and chemical properties. In this work, a dispersion treatment of the TiO2 nanoparticles with different average sizes was employed to improve the dispersion of TiO2 nanoparticles, in order to prepare flexible photoanodes for dye-sensitized solar cells (DSCs) with novel photovoltaic properties at a low temperature. The effects of dispersion treatment on the dispersion of TiO2 nanoparticles, including the viscosities of the binder-free TiO2 paste, the morphologies and textural properties of nanoparticle-TiO2 films, and the photovoltaic properties of the flexible DSCs, were investigated. Flexible indium-tin oxide (ITO)-coated polyethylene naphthalate (PEN) substrates with sputter deposited Pt were employed as the transparent flexible counter electrodes. A short-circuit photocurrent density of 9.62 mA·cm 2, an open-circuit voltage of 0.757 V, a fill factor of 0.589 and an overall light-to-energy conversion efficiency of 4.29% for the flexible DSCs under AM1.5 illumination of 100 mW cm 2 were obtained with dispersion treatment. A 30.8% increment of the energy conversion efficiency for DSCs made by dispersion treatment was obtained compared with that made without dispersion treatment. | ZHAO XiaoChong LIN Hong LIU YiZhu LI Xin YANG Pan CHEN HuiYuan WANG Gang LI JianBao | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，7： | 0 |
| 3 | Fabrication of flexible α-MnO_2 nanowire membranes with superior mechanical strength显示文摘The Assembly of one-dimensional(1D)nanostructures such as nanowires/nanorods/nanotubes into twodimensional(2D)macrostructured films is attracting considerable research interest because of their unique properties and wide applications.In this study,flexible membranes were successfully fabricated using a-MnO2nanowires synthesized through a hydrothermal method.The effects of thickness and post-annealing temperature on the mechanical properties of the membranes were investigated in detail.Nano-indentation measurements showed that the modulus of the as-prepared 11.75 lm-thick membrane reached5.765 GPa,and the modulus increased with the increasing post-annealing temperature.Thus,the fabricated membranes with superior mechanical strength can have potential applications such as in photocatalysis,filtering,and supporting substrates. | Xingyue Zhao Xiaochong Zhao Jianbao Li Xiangyun Deng Hong Lin | 2014 | Chinese Science Bulletin2014，59，13： | 0 |
| 4 | Leptin promotes proliferation and invasion of osteosarcoma cells by upregulating the expression of SIRT1显示文摘Osteosarcoma(OS)is a primary high-grade malignant bone neoplasm,and the prognosis ofOS remains poor due to early metastasis.Leptin plays an essential role in tumorigenesis,but the role of leptin in the development of OS is still not fully understood.In this study,we used a human osteosarcomaMG-63 cell line as an experimentalmodel.MG-63 cells were treated with leptin,and cell proliferation,apoptosis,adhesion,invasion,and gene expression,were evaluated.The results showed that leptin promoted proliferation,decreased adhesion,suppressed apoptosis,and promoted invasion,of MG-63 cells.Moreover,the expression of SIRT1 was upregulated in MG-63 cells exposed to leptin.Furthermore,MMP-2,8,and 9 were significantly upregulated by SIRT1,while SIRT1 knockdown inhibited the proliferation and invasion of MG-63 cells.In conclusion,our results suggest that leptin promotes OS cell proliferation and invasion by inducing the expression of SIRT1. | HELIN FENG XIAOCHONG ZHANG QIANQIAN ZHANG ZE LI LILI ZHAO | 2020 | BIOCELL2020，44，3： | 0 |
