2I Have a Dream显示文摘Qu Geping was born in June 1930 in Feicheng,Shandong Province.In 1976 he was appointed China’s chief representative to the United Nations Environment Program(UNEP),and later became the first director of the State Bureau of Environmental Protection and chairman of the Environmental Protection and Resources Conservation Committee of the National People’s Congress (NPC).He received many international awards for his outstanding contributions, including the UNEP Sasakawa Environment Prize in 1992 and the Blue Planet Prize in 1999.QU GEPING LI YONGFENG 2009China Today2009,58,10:0
3Primary pulmonary rhabdomyosarcoma in adult:A case report显示文摘Primary pulmonary rhabdomyosarcoma (PPR) in adult is an extremely rare disease, and because of its early metastasis, the prognosis of it is poor. PPR should be included in consideration in the diagnosis and differential diagnosis of lung tumors.Qu Geping Xiu Qingyu Li Bing Shi Zhaoquan 2009Journal of Medical Colleges of PLA(China)2009,24,6:0
4Spontaneous decoration of ionic compounds at perovskite interfaces to achieve 23.38% efficiency with 85% fill factor in NiO_X-based perovskite solar cells显示文摘Inorganic hole transport materials, particularly NiO_X, have shown considerable promise in boosting the efficiency and stability of perovskite solar cells. However, a major barrier to commercialization of NiO_X-based perovskite solar cells with positive-intrinsic-negative architectures is their direct contact with the absorbing layer, which can lead to losses of photovoltage and fill factor. Furthermore, highly positive under-coordinated Ni cations degrade the perovskite at the interface. Here, we address these issues with the use of an ionic compound(QAPyBF_(4)) as an additive to passivate defects throughout the perovskite layer and improve carrier conduction and interactions with under-coordinated Ni cations. Specifically,the highly electronegative inorganic anion [BF_(4)]~- interacts with the NiO_x/perovskite interface to passivate under-coordinated cations(Ni^(≥3+)). Accordingly, the decorated cells achieved a power conversion efficiency of 23.38% and a fill factor of 85.5% without a complex surface treatment or NiO_X doping.Geping Qu Deng Wang Xiaoyuan Liu Ying Qiao Danish Khan Yinxin Li Jie Zeng Pengfei Xie Yintai Xu Peide Zhu Limin Huang Yang-Gang Wang Baomin Xu Zong-Xiang Xu 2023Journal of Energy Chemistry2023,,10:0
5Reformation of thiophene-functionalized phthalocyanine isomers for defect passivation to achieve stable and efficient perovskite solar cells显示文摘Lewis acid–base passivation is a significant technique to achieve structural stability of perovskite solar cells(PSCs) by overcoming the issues of wide grain boundaries, crystal defects, and the instability of PSCs. In this work, the combined effects of thiophene with phthalocyanine(Pc) as isomers(S2 and S3)on the photovoltaic performance of PSCs were studied for the first time. Through density functional theory calculations, we confirmed that the position of the S atom in the structure affects Lewis acid–base interactions with under-coordinated Pb^(2+) sites. The morphology of methylammonium lead iodide(MAPbI_(3)) for passivated devices was improved and thin dense layers with compact surface and large grain size were observed, leading to improvement of the charge extraction ability and reduction of non-radiative recombination and the trap density. A highest power conversion efficiency of 18% was achieved for the Pc S3 passivated device, which was 6.69% more than that of the controlled device.Furthermore, the Pcs passivated devices demonstrated remarkable stability under high-moisture and high-temperature conditions.Geping Qu Danish Khan Feini Yan Armağan Atsay Hui Xiao Qian Chen Hu Xu Ilgın Nar Zong-Xiang Xu 2022Journal of Energy Chemistry2022,31,4:0
6{332}<113> Twinning transfer behavior and its effect on the twin shape in a beta-type Ti-23.1Nb-2.0Zr-1.0O alloy显示文摘The interaction between twins and grain boundaries(GB) has an important influence on the deformation and fracture behavior of materials. In the present work, {332}<113> twinning transfer(TT) behavior and its effect on the twin shape in a deformed β-type Ti-23.1 Nb-2.0 Zr-1.0 O Ti alloy were investigated experimentally and with molecular dynamics simulation. The crystallographic alignment factor of the two twinning systems in the neighboring grains and the misorientation angle of the grain pairs were found to influence the occurrence of TT. This further determines the twin shape: twins present a ruler shape when TT occurs but are in a lenticular shape otherwise. Such different twin shapes are attributed to the local stress states related to TT occurring or not. Both ruler-shaped paired twinning and lenticular twinning would provide effective mechanisms to release or reduce the stress concentration in front of the twin tips in different grain pairs.Yi Yang Bohua Zhang Zhichao Meng Lei Qu Hao Wang Sheng Cao Jianan Hu Hao Chen Songquan Wu Dehai Ping Geping Li Lai-Chang Zhang Rui Yang Aijun Huang 2021Journal of Materials Science & Technology2021,,32:0
7Preface to the inaugural issue of Environmental Science & Ecotechnology显示文摘The international journal Environmental Science&Ecotechnology(ESE),co-organized by the Chinese Society for Environmental Sciences,Harbin Institute of Technology and Chinese Research Academy of Environmental Sciences,is launched in 2020.ESE aims to cover cutting-edge environmental science and ecotechnology research in a timely fashion.It is positioned to build an influential and professional exchange platform for the global scientific community.This is an important step to build an ecological civilization and a beautiful China,achieve green and sustainable development,and fulfill our commitment to the campaign of global environmental improvement.Geping Qu 2020Environmental Science and Ecotechnology2020,,1:0
