| 1 | Biomarkers of aging显示文摘Aging biomarkers are a combination of biological parameters to(i)assess age-related changes,(ii)track the physiological aging process,and(iii)predict the transition into a pathological status.Although a broad spectrum of aging biomarkers has been developed,their potential uses and limitations remain poorly characterized.An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research:How old are we?Why do we get old?And how can we age slower?This review aims to address this need.Here,we summarize our current knowledge of biomarkers developed for cellular,organ,and organismal levels of aging,comprising six pillars:physiological characteristics,medical imaging,histological features,cellular alterations,molecular changes,and secretory factors.To fulfill all these requisites,we propose that aging biomarkers should qualify for being specific,systemic,and clinically relevant. | Aging Biomarker Consortium Hainan Bao Jiani Cao Mengting Chen Min Chen Wei Chen Xiao Chen Yanhao Chen Yu Chen Yutian Chen Zhiyang Chen Jagadish K Chhetri Yingjie Ding Junlin Feng Jun Guo Mengmeng Guo Chuting He Yujuan Jia Haiping Jiang Ying Jing Dingfeng Li Jiaming Li Jingyi Li Qinhao Liang Rui Liang Feng Liu Xiaoqian Liu Zuojun Liu Oscar Junhong Luo Jianwei Lv Jingyi Ma Kehang Mao Jiawei Nie Xinhua Qiao Xinpei Sun Xiaoqiang Tang Jianfang Wang Qiaoran Wang Siyuan Wang Xuan Wang Yaning Wang Yuhan Wang Rimo Wu Kai Xia Fu-Hui Xiao Lingyan Xu Yingying Xu Haoteng Yan Liang Yang Ruici Yang Yuanxin Yang Yilin Ying Le Zhang Weiwei Zhang Wenwan Zhang Xing Zhang Zhuo Zhang Min Zhou Rui Zhou Qingchen Zhu Zhengmao Zhu Feng Cao Zhongwei Cao Piu Chan Chang Chen Guobing Chen Hou-Zao Chen Jun Chen Weimin Ci Bi-Sen Ding Qiurong Ding Feng Gao Jing-Dong JHan Kai Huang Zhenyu Ju Qing-Peng Kong Ji Li Jian Li Xin Li Baohua Liu Feng Liu Lin Liu Qiang Liu Qiang Liu Xingguo Liu Yong Liu Xianghang Luo Shuai Ma Xinran Ma Zhiyong Mao Jing Nie Yaojin Peng Jing Qu Jie Ren Ruibao Ren Moshi Song Zhou Songyang Yi Eve Sun Yu Sun Mei Tian Shusen Wang Si Wang Xia Wang Xiaoning Wang Yan-Jiang Wang Yunfang Wang Catherine CL Wong Andy Peng Xiang Yichuan Xiao Zhengwei Xie Daichao Xu Jing Ye Rui Yue Cuntai Zhang Hongbo Zhang Liang Zhang Weiqi Zhang Yong Zhang Yun-Wu Zhang Zhuohua Zhang Tongbiao Zhao Yuzheng Zhao Dahai Zhu Weiguo Zou Gang Pei Guang-Hui Liu | 2023 | Science China(Life Sciences)2023，66，5： | 2 |
| 2 | Single-event burnout hardening of planar power MOSFET with partially widened trench source显示文摘We present a single-event burnout(SEB) hardened planar power MOSFET with partially widened trench sources by three-dimensional(3 D) numerical simulation. The advantage of the proposed structure is that the work of the parasitic bipolar transistor inherited in the power MOSFET is suppressed effectively due to the elimination of the most sensitive region(P-well region below the N+ source). The simulation result shows that the proposed structure can enhance the SEB survivability significantly. The critical value of linear energy transfer(LET),which indicates the maximum deposited energy on the device without SEB behavior, increases from 0.06 to0.7 p C/μm. The SEB threshold voltage increases to 120 V, which is 80% of the rated breakdown voltage. Meanwhile, the main parameter characteristics of the proposed structure remain similar with those of the conventional planar structure. Therefore, this structure offers a potential optimization path to planar power MOSFET with high SEB survivability for space and atmospheric applications. | Jiang Lu Hainan Liu Xiaowu Cai Jiajun Luo Bo Li Binhong Li Lixin Wang Zhengsheng Han | 2018 | Journal of Semiconductors2018，39，3： | 1 |
| 3 | Polydopamine nanolayer assisted internal photo-deposition of CdS nanocrystals for stable cosensitized photoanode显示文摘Hydrogen evolution via photo-electro-chemical(PEC)co-catalysis is potential for solving energy crisis and environmental issues.The rapidly advances of fabrication and broad applications of polydopamine(PDA)and its derivatives have drawn intense attentions in recent years.Herein,an ultrathin PDA coating with nanometer accuracy was conformally grown on TiO_(2) nanotube arrays(NTAs)via electrochemical polymerization,in which the polymer provided a platform for further photoinduced assembly of CdS nanocrystals in the embedded mode.The optimized CdS@PDA/TiO_(2) NTAs hierarchical heterostructure as photoanode gave an excellent PEC performance and exhibited outstanding stability under light irradiation.The photocurrent density was heightened to 5.48 mA·cm^(–2),which was beneficial to H_(2) evolution with a rate of 20μmol·h^(–1)·cm^(–2).The improvement of PEC activity was ascribed to co-photosensitization,optimized carriers transfer,and transport route arised from CdS embedding,resulting to provide a persistent driving force for charge separation based on secure heterojunction of CdS/TiO_(2) glued by PDA.The improvement of PEC stability was due to the inhibition of CdS photocorrosion covered by PDA shelter.This advance boded well for the development of PEC field founded on multifunctional PDA. | Na Li Lu Han Hainan Zhang Juntong Huang Xudong Luo Xibao Li Yuanhao Wang Weiqi Qian Ya Yang | 2022 | Nano Research2022，15，10： | 0 |

| 5 | Effect of mass transfer process on hydrogen adsorption on polycrystalline platinum electrode in sulfuric acid solution显示文摘The underpotential adsorption of hydrogen (HUPD) is one of the most attractive fields in surface electrochemistry and electrocatalysis. In this work, the hydrogen adsorption on polycrystalline platinum electrode experimentally as well as on single crystal Pt(110) and Pt(100) electrode theoretically were studied. The effect of forced convection on the adsorption and desorption process of hydrogen was studied through adjusting the sampling rate of the microporous sampler closing to the surface of the platinum electrode immersed in dilute sulfuric acid solution. The relationship between HUPD and surface structure sensitivity was built quantitively. The DFT simulation shows that the adsorption strength of hydrogen on Pt(100), due to the lower adsorption energy, is weaker than that on Pt(110). Moreover, the bridged position of hydrogen on Pt(100) and the short-range bridged position on Pt(110) were found to be the optimal adsorption sites. The study of forced convection on the electrode surface promotes the HUPD research from static process to a convective mode and also provides a new strategy to investigate the hydrogen adsorption in solution. | Wei Zhang Yang Liu Hainan Luo Changwei Pan | 2019 | Chinese Chemical Letters2019，30，6： | 0 |
