| 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 | An outbreak of Mycobacterium marinum infection associated with handling seabass in China显示文摘To the Editor:Mycobacterium marinum is a nontuberculous mycobacterium that can cause opportunistic infections in humans,ranging from a single cutaneous lesion to disseminated disease.[1]It was first isolated from a fish in 1926 and identified as a cause of human infection in 1951.[1]The estimated annual incidence ranges from 0.04 to 0.27 per 100,000 persons in different countries.Outbreaks of M.marinum infections related to handling fish are not common,but have also been reported. | Qing Zhao Fangfang Bao Zihao Mi Zhenzhen Wang Pengcheng Huai Qing Pan Zheng Pang Yaoming Li Nan Cao Xiaotong Xue Buyan Li Xuechao Chen Jinliang Wang Yanxia Cui Wenqian Chang Yuan Zhang Zhenhua Yue Yongxia Liu Zhenhua Wang Weiguo Yan Jinyong Li Hongqing Tian Xianmei Lu Guizhi Zhou Jianjun Liu Hong Liu Furen Zhang | 2022 | Chinese Medical Journal2022，135，21： | 1 |
| 3 | Bone morphogenetic protein 4 (BMP4) promotes hepatic glycogen accumulation and reduces glucose level in hepatocytes through mTORC2 signaling pathway显示文摘Liver is an important organ for regulating glucose and lipid metabolism.Recent studies have shown that bone morphogenetic proteins(BMPs)may play important roles in regu-lating glucose and lipid metabolism.Inour previous studies,we demonstrated that BMP4 signif-icantly inhibits hepatic steatosis and lowers serum triglycerides,playing a protective role against the progression of non-alcoholic fatty liver disease(NAFLD).However,the direct impact of BMP4 on hepatic glucose metabolism is poorly understood.Here,we investigated the regulatory roles of BMP4 in hepatic glucose metabolism.Through a comprehensive analysis of the 14 types of BMPs,we found that BMP4 was one of the most potent BMPs in promoting hepatic glycogen accumulation,reducing the level of glucose in hepatocytes and effecting the expression of genes related to glucose metabolism.Mechanistically,we demonstrated that BMP4 reduced the hepatic glucose lewels through the activation of mTORC2 signaling pathway in vitro and in wivo.Collectively,our findings strongly suggest that BMP4 may play an essential role in regulating hepatic glucose metabolism.This knowledge should aid us to understand the molecular pathogenesis of NAFLD,and may lead to the development of novel therapeutics by exploiting the inhibitory effects of BMPs on hepatic glucose and lipid metabolism. | Liqin An Qiong Shi Ying Zhu Hao Wang Qi Peng Jinghong Wu Yu Cheng Wei Zhang Yanyu Yi Zihao Bao Hui Zhang Yetao Luo Jiaming Fan | 2021 | Genes & Diseases2021，8，4： | 1 |
| 4 | Ring-VCO-based phase-locked loops for clock generation–design considerations and state-of-the-art显示文摘This article overviews the design considerations and state-of-the-art of the ring voltage-controlled oscillator(VCO)-based phase-locked loops(PLLs)for clock generation in different applications.Partic-ularly,the objective of the current work is to evaluate the required PLL performance among the fundamental metrics of power,jitter and area.An in-depth treatment of the mainstream PLL architectures and the associated design techniques enables them to be compared analyt-ically and benchmarked with respect to their figure-of-merit(FoM).The paper also summarizes the key concerns on the selection of dif-ferent circuit techniques to optimize the clock performance under dif-ferent scenarios. | Shiheng Yang Jun Yin Yueduo Liu Zihao Zhu Rongxin Bao Jiahui Lin Haoran Li Qiang Li Pui-In Mak Rui P.Martins | 2023 | Chip2023，2，2： | 0 |
| 5 | Weighting Function Modification Used for Phase Transform-Based Time Delay Estimation显示文摘Generalized cross-correlation is considered as the most straightforward time delay estimation algorithm.Depending on various weighting function,different methods were derived and a straightforward method,named phase transform(PHAT)has been widely used.PHAT is well-known for its robustness to reverberation and its sensitivity to noise,which is partly due to the fact that PHAT distributes same weights to the frequencies dominated by signal or noise.To alleviate this problem,two weighting functions are proposed in this paper.By taking a posteriori signal-to-noise ratio(SNR)into account to classify reliable and unreliable frequencies,different weights could be assigned.The first proposed weighting function borrows the idea of binary mask and distributes same weights to frequencies in same set,whereas,the second one assigns weights based on coherence function.Experiments showed the robustness of proposed methods to reverberation and noise for improving the performance of time delay estimation through various criteria. | Xue Yang Changchun Bao Zihao Cui | 2022 | China Communications2022，19，11： | 0 |
| 6 | Mitigating fast thermal instability by engineered laser sweep in AlN soliton microcomb generation显示文摘Transient thermal instability represents a significant challenge in generating soliton microcombs.Fast laser sweep can be an efficient method to mitigate thermal instability,but it requires an ultrahigh laser sweep rate for crystalline microresonators with fast thermal relaxation.Here,we engineer a laser sweep waveform to generate AlNon-sapphire soliton microcombs with an intermediate sweep speed(<30 GHz∕μs).Two laser sweep methods with backward plus forward tuning or two-step backward tuning added after the fast forward laser sweep were demonstrated to stabilize solitons.Reducing the soliton number is found to be useful to stabilize solitons in fast laser sweep.The effectiveness of the methods was numerically verified.Our measurements and simulations also reveal the impacts of different thermal relaxation processes occurring at quite different time scales on thermal instability.The requirement of the laser sweep protocols is discussed. | KEWEI LIU ZIHAO WANG SHUNYU YAO YANAN GUO JIANCHANG YAN JUNXI WANG CHANGXI YANG CHENGYING BAO | 2023 | Photonics Research2023，11，8： | 0 |
| 7 | Tuning the ratio of Bi/Bi_(2)O_(3)in Bi/PNC nanosheet for highefficiency electrosynthesis hydrogen peroxide显示文摘Electrocatalytic two-electron oxygen reduction reaction(2e-ORR)is a promising method for producing green and sustainable H_(2)O_(2)but lacks high selectivity and yields electrocatalysts.And it is critical to develop catalysts that meet industrial demands.Herein,we report the different ratios of Bi0/Bi^(3+)supported on a phosphorus,nitrogen,and carbon nanosheet(Bi/PNC),which can reduce O_(2) to H_(2)O_(2)with high selectivity(up to 97.75%at 0.4 VRHE)in 0.1 M KOH electrolyte and retain 97%selectivity even after 100 h electrolysis.Then a homemade flow-cell system was built for electrocatalytic production of H_(2)O_(2)under an O_(2) atmosphere using an improved gas diffusion electrode.The Bi/PNC-4 can achieve a high H_(2)O_(2)yield of 2.76 mol·gcatalyst^(-1)·h^(-1)(alkaline),5.29 mol·gcatalyst^(-1)·h^(-1)(neutral),and 3.50 mol·gcatalyst^(-1)·h^(-1)(acid)in universal pH conditions.The in-situ generated H_(2)O_(2)can function as a degradation agent for efficiently degrading pesticides and antibiotics.The outstanding selectivity and activities are attributed to the synergistic effects of Bi0 and Bi^(3+)that promote proton-coupled reduction of O_(2) to OOH^(*)(ΔGOOH^(*)=4.27 eV),and the formation of H_(2)O_(2).The fast yield of H_(2)O_(2)on Bi/PNC catalysts in flow-cell provides a promising path of electrocatalytic 2e-ORR for practical H_(2)O_(2)production. | Zhikang Bao Jinyan Zhao Shijie Zhang Xiaoge Peng Yizhen Shao Chenghang Jiang Zaixiang Xu Xing Zhong Zihao Yao Jianguo Wang | 2023 | Nano Research2023，16，7： | 0 |
