| 1 | Trace water triggers high-efficiency photocatalytic hydrogen peroxide production显示文摘Photocatalytic production of hydrogen peroxide(H_(2)O_(2))has attracted much attentions as a promising method for sustainable solar fuel.Here,we demonstrate that trace water can drastically boost highefficiency photocatalytic production of H_(2)O_(2) with a record-high concentration of 113 mmol L^(-1) using alkali-assisted C_(3)N_(4) as photocatalyst in water/alcohol mixture solvents.By electron paramagnetic resonance(EPR)measurement,the radical species generated during the photocatalytic process of H_(2)O_(2) are identified.We propose alcohol is used to provide and stabilize-OOH radicals through hydrogen bond,while trace water could trigger photocatalytic production of H_(2)O_(2) via providing and transferring indispensable free protons to completely consume OOH radicals,which breaks the reaction balance of-OOH radical generation from alcohol.Thus-OOH radicals could be supplied by alcohol continuously to serve as a reservoir for high-efficiency production of H_(2)O_(2).These results pave the way towards photocatalytic method on semiconductor catalysts as an outstanding approach for production of hydrogen peroxide. | Zaixiang Xu Yang Li Yongyong Cao Renfeng Du Zhikang Bao Shijie Zhang Fangjun Shao Wenkai Ji jun Yang Guilin Zhuang Shengwei Deng Zhongzhe Wei Zihao Yao Xing Zhong Jianguo Wang | 2022 | Journal of Energy Chemistry2022，31，1： | 1 |
| 2 | OTUB1 promotes osteoblastic bone formation through stabilizing FGFR2显示文摘Bone homeostasis is maintained by the balance between osteoblastic bone formation and osteoclastic bone resorption.Dysregulation of this process leads to multiple diseases,including osteoporosis.However,the underlying molecular mechanisms are not fully understood.Here,we show that the global and conditional osteoblast knockout of a deubiquitinase Otub1 result in low bone mass and poor bone strength due to defects in osteogenic differentiation and mineralization.Mechanistically,the stability of FGFR2,a crucial regulator of osteogenesis,is maintained by OTUB1.OTUB1 attenuates the E3 ligase SMURF1-mediated FGFR2 ubiquitination by inhibiting SMURF1’s E2 binding.In the absence of OTUB1,FGFR2 is ubiquitinated excessively by SMURF1,followed by lysosomal degradation.Consistently,adeno-associated virus serotype 9(AAV9)-delivered FGFR2 in knee joints rescued the bone mass loss in osteoblast-specific Otub1-deleted mice.Moreover,Otub1 mRNA level was significantly downregulated in bones from osteoporotic mice,and restoring OTUB1 levels through an AAV9-delivered system in ovariectomy-induced osteoporotic mice attenuated osteopenia.Taken together,our results suggest that OTUB1 positively regulates osteogenic differentiation and mineralization in bone homeostasis by controlling FGFR2 stability,which provides an optical therapeutic strategy to alleviate osteoporosis. | Qiong Zhu Yesheng Fu Chun-Ping Cui Yi Ding Zhikang Deng Chao Ning Fan Hu Chen Qiu Biyue Yu Xuemei Zhou Guan Yang Jiang Peng Weiguo Zou Cui Hua Liu Lingqiang Zhang | 2023 | Signal Transduction and Targeted Therapy2023，8，5： | 1 |

| 5 | Economic Development Strategies and Optimization of High-tech Development Zones from the Perspective of'Four-transform and Three-famous':Taking Nanchang High-tech Development Zone as an Example显示文摘In recent years,high-tech development zones(hi-tech zones)have always occupied a very important position in the strategy of promoting China's innovative development.The combination of the'four-transform and three-famous'coordinated economic development strategy pioneered by Zhejiang Province in 2015 and the coordinated economic development of high-tech zones is particularly important for modern China at a critical time for innovative economic development.In this article,based on the research on the coordination mechanism of economic activities and development of Nanchang High-tech Zone,the development course of high-tech zones in China is elaborated,the early economic models in high-tech zones of Nanchang and China are analyzed,the existing problems in the structure of economic development of high-tech zones are analyzed in depth,the main driving factors for promoting the economic development of high-tech zones are studied from the aspects of capital,space,industry,economic model,etc.,and corresponding development strategies for high-tech development zones in China are proposed. | Zhikang DENG Meixuan REN | 2020 | Asian Agricultural Research2020，12，7： | 0 |
