1Rambutan-like hollow carbon spheres decorated with vacancy-rich nickel oxide for energy conversion and storage显示文摘Transition metal oxides hold great promise for lithium-ion batteries(LIBs)and electrocatalytic water splitting because of their high abundance and high energy density.However,designing and fabrication of efficient,stable,high power density electrode materials are challenging.Herein,we report rambutan-like hollow carbon spheres formed by carbon nanosheet decorated with nickel oxide(NiO)rich inmetal vacancies(denoted as h-NiO/C)as a bifunctional electrode material for LIBs and electrocatalytic oxygen evolution reaction(OER).When being used as the anode of LIBs,the h-NiO/C electrode shows a large initial capacity of 885mAh g−1,a robust stability with a high capacity of 817mAh g−1 after 400 cycles,and great rate capability with a high reversible capacity of 523mAh g−1 at 10Ag−1 after 600 cycles.Moreover,working as an OER electrocatalyst,the h-NiO/C electrode shows a small overpotential of 260mV at 10mAcm−2,a Tafel slope of 37.6mVdec−1 along with good stability.Our work offers a cost-effective method for the fabrication of efficient electrode for LIBs and OER.Zixu Sun Xinghui Wang Hu Zhao See W.Koh Junyu Ge Yunxing Zhao Pingqi Gao Guangjin Wang Hong Li 2020Carbon Energy2020,2,1:4
2Refining the ERA5-based global model for vertical adjustment of zenith tropospheric delay显示文摘Tropospheric delay is an important factor affecting high precision Global Navigation Satellite System(GNSS)positioning and also the basic data for GNSS atmospheric research.However,the existing tropospheric delay models have some problems,such as only a single function used for the entire atmosphere.In this paper,an ERA5-based(the fifth generation of European Centre for Medium-Range Weather Forecasts Reanalysis)global model for vertical adjustment of Zenith Tropospheric Delay(ZTD)using a piecewise function is developed.The ZTD data at 611 radiosonde stations and the MERRA-2(second Modern-Era Retrospective analysis for Research and Applications)atmospheric reanalysis data were used to validate the model reliability.The Global Zenith Tropospheric Delay Piecewise(GZTD-P)model has excellent performance compared with the Global Pressure and Temperature(GPT3)model.Validated at radiosonde stations,the performance of the GZTD-P model was improved by 0.96 cm(23%)relative to the GPT3 model.Validated with MERRA-2 data,the quality of the GZTD-P model is improved by 1.8 cm(50%)compared to the GPT3 model,showing better accuracy and stability.The ZTD vertical adjustment model with different resolutions was established to enrich the model's applicability and speed up the process of tropospheric delay calculation.By providing model parameters with different resolutions,users can choose the appropriate model according to their applications.Ge Zhu Liangke Huang Yunzhen Yang Junyu Li Lv Zhou Lilong Liu 2022Satellite Navigation2022,3,3:1
3Photovoltaic-powered supercapacitors for driving overall water splitting:A dual-modulated 3D architecture显示文摘Due to the growing demand for clean and renewable hydrogen fuel,there has been a surge of interest in electrocatalytic water-splitting devices driven by renewable energy sources.However,the feasibility of self-driven water splitting is limited by inefficient connections between functional modules,lack of highly active and stable electrocatalysts,and intermittent and unpredictable renewable energy supply.Herein,we construct a dualmodulated three-dimensional(3D)NiCo_(2)O_(4)@NiCo_(2)S_(4)(denoted as NCONCS)heterostructure deposited on nickel foam as a multifunctional electrode for electrocatalytic water splitting driven by photovoltaic-powered supercapacitors.Due to a stable 3D architecture configuration,abundant active sites,efficient charge transfer,and tuned interface properties,the NCONCS delivers a high specific capacity and rate performance for supercapacitors.A twoelectrode electrolyzer assembled with the NCONCS as both the anode and the cathode only requires a low cell voltage of 1.47 V to achieve a current density of 10 mA cm^(−2) in alkaline electrolyte,which outperforms the state-of-the-art bifunctional electrocatalysts.Theoretical calculations suggest that the generated heterointerfaces in NCONCS improve the surface binding capability of reaction intermediates while regulating the local electronic structures,which thus accelerates the reaction kinetics of water electrolysis.As a proof of concept,an integrated configuration comprising a two-electrode electrolyzer driven by two series-connected supercapacitors charged by a solar cell delivers a high product yield with superior durability.Zixu Sun Lijuan Sun See Wee Koh Junyu Ge Jipeng Fei Mengqi Yao Wei Hong Shude Liu Yusuke Yamauchi Hong Li 2022Carbon Energy2022,4,6:0
4LLG2/3作为复合体的共受体参与调控花粉管破裂显示文摘文章简介在被子植物的有性生殖过程中,花粉管是精细胞的运输载体,它经历与雌方多种组织和细胞的相互作用,最终将精细胞送至雌配子体进行双受精。为了鉴定参与花粉管细胞完整性调控的其他因子,课题组在系统地分析了拟南芥中的GPI-AP基因之后,发现了两个与LRE/LLG1相似、相互之间序列又非常相似的GPI-AP基因LLG2和LLG3,这两个基因在花粉中大量表达。Zengxiang Ge Yuling Zhao Ming-Che Liu Liang-Zi Zhou Lele Wang Sheng Zhong Saiying Hou Jiahao Jiang Tianxu Liu Qingpei Huang Junyu Xiao Hongya Gu Hen-Ming Wu Juan Dong Thomas Dresselhaus Alice Y.Cheung 瞿礼嘉 2020科学新闻2020,,2:0
