| 1 | Oxygen as a catalyst in the Earth’s interior?显示文摘The abundance of the element oxygen is not only crucial for life at the surface of the Earth,but also greatly affects the properties and dynamics of the interior of our planet.The combination of a highly oxidized atmosphere and a large reduced metallic core makes our Earth unique among the terrestrial planets. | Yanhao Lin Wim van Westrenen | 2021 | National Science Review2021，8，4： | 2 |
| 2 | 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 |
| 3 | Pressureless two-step sintering of ultrafine-grained refractory metals:Tungsten-rhenium and molybdenum显示文摘The challenge of sintering ultrafine-grained refractory metals and alloys to full density is hereby addressed by pressureless two-step sintering in tungsten-rhenium alloy and pure molybdenum. Using properly processed nano powders(~50 nm average particle size), we are able to sinter W-10Re alloy to 98.4% density below 1200 ℃ while maintaining a fine grain size of 260 nm, and sinter molybdenum to 98.3% density below 1120 ℃ while maintaining a fine grain size of 290 nm. Compared to normal sintering,two-step sintering offers record-fine grain sizes and better microstructural uniformity, which translates to better mechanical properties with higher hardness(6.3 GPa for tungsten-rhenium and 4.0 GPa for molybdenum, both being the highest in all pressurelessly sintered samples of the respective material system)and larger Weibull modulus. Together with our previous demonstration in tungsten, we believe that twostep sintering is a general effective method to produce high-quality fine-grained refractory metals and alloys, and the lessons learned here are transferable to other materials for powder metallurgy. | Zhongyou Que Zichen Wei Xingyu Li Lin Zhang Yanhao Dong Mingli Qin Junjun Yang Xuanhui Qu Ju Li | 2022 | Journal of Materials Science & Technology2022，，31： | 1 |
| 4 | Applications of 2D-Layered Palladium Diselenide and Its van der Waals Heterostructures in Electronics and Optoelectronics显示文摘The rapid development of two-dimensional(2D)transition-metal dichalcogenides has been possible owing to their special structures and remarkable properties.In particular,palladium diselenide(PdSe_(2))with a novel pentagonal structure and unique physical characteristics have recently attracted extensive research inter-est.Consequently,tremendous research progress has been achieved regarding the physics,chemistry,and electronics of PdSe_(2).Accordingly,in this review,we recapitulate and summarize the most recent research on PdSe_(2),including its structure,properties,synthesis,and appli-cations.First,a mechanical exfoliation method to obtain PdSe_(2) nanosheets is introduced,and large-area synthesis strate-gies are explained with respect to chemical vapor deposition and metal selenization.Next,the electronic and optoelectronic properties of PdSe_(2) and related hetero-structures,such as field-effect transistors,photodetectors,sensors,and thermoelec-tric devices,are discussed.Subsequently,the integration of systems into infrared image sensors on the basis of PdSe_(2) van der Waals heterostructures is explored.Finally,future opportunities are highlighted to serve as a general guide for physicists,chemists,materials scientists,and engineers.Therefore,this com-prehensive review may shed light on the research conducted by the 2D material community. | Yanhao Wang Jinbo Pang Qilin Cheng Lin Han Yufen Li Xue Meng Bergoi Ibarlucea Hongbin Zhao Feng Yang Haiyun Liu Hong Liu Weijia Zhou Xiao Wang Mark HRummeli Yu Zhang Gianaurelio Cuniberti | 2021 | Nano-Micro Letters2021，13，9： | 1 |
| 5 | Application of a real-ambient fine particulate matter exposure system on different animal models显示文摘Simulation of fine particulate matter(PM_(2.5))exposure is essential for evaluating adverse health effects.In this work,an ambient exposure system that mimicked real atmospheric conditions was installed in Taiyuan,China to study impacts of chronic PM_(2.5) exposure on adult and aged mice as well as Sirtuin3 knockout(Sirt3 KO)mice and wild-type(WT)mice.The real-ambient exposure system eliminated the possible artificial effects caused from exposure experiments and maintained the physiochemical characteristics of PM_(2.5).The case studies indicated that aged mice exhibited apparent heart dysfunction involving in-creased heart rate and decreased blood pressure after 17-week of real-ambient PM_(2.5) exposure.Meanwhile,15-week of real-ambient PM_(2.5) exposure decreased the heart rate and amounts of associated catecholamines to induce heart failure in Sirt3 KO mice.Additionally,the increased pro-inflammatory cytokines and decreased platelet related indices suggested that inflammation occurred.The changes of biomarkers detected by targeted metabolomics confirmed metabolic disorder in WT and Sirt3 KO mice after exposed to real-ambient PM_(2.5).These results indicated that the real-ambient PM_(2.5) exposure system could evaluate the risks of certain diseases associated with air pollution and have great potential for support-ing the investigations of PM_(2.5) effects on other types of rodent models. | Yuanyuan Song Lifang Zhao Zenghua Qi Yanhao Zhang Guodong Cao Ruijin Li Lin Zhu Zhu Yang Chuan Dong Zongwei Cai | 2021 | Journal of Environmental Sciences2021，33，7： | 1 |
| 6 | Multi-omics analysis of attenuated variant reveals potential evaluation marker of host damaging for SARS-CoV-2 variants显示文摘SARS-CoV-2 continues to threaten human society by generating novel variants via mutation and recombination.The high number of mutations that appeared in emerging variants not only enhanced their immune-escaping ability but also made it difficult to predict the pathogenicity and virulence based on viral nucleotide sequences.Molecular markers for evaluating the pathogenicity of new variants are therefore needed.By comparing host responses to wild-type and variants with attenuated pathogenicity at proteome and metabolome levels,six key molecules on the polyamine biosynthesis pathway including putrescine,SAM,dc-SAM,ODC1,SAMS,and SAMDC were found to be differentially upregulated and associated with pathogenicity of variants.To validate our discovery,human airway organoids were subsequently used which recapitulates SARS-CoV-2 replication in the airway epithelial cells of COVID-19 patients.Using ODC1 as a proof-ofconcept,differential activation of polyamine biosynthesis was found to be modulated by the renin-angiotensin system(RAS)and positively associated with ACE2 activity.Further experiments demonstrated that ODC1 expression could be differentially activated upon a panel of SARS-CoV-2 variants of concern(VOCs)and was found to be correlated with each VOCs’pathogenic properties.Particularly,the presented study revealed the discriminative ability of key molecules on polyamine biosynthesis as a predictive marker for virulence evaluation and assessment of SARS-CoV-2 variants in cell or organoid models.Our work,therefore,presented a practical strategy that could be potentially applied as an evaluation tool for the pathogenicity of current and emerging SARS-CoV-2 variants. | Guangshan Xie Lin Zhu Siwen Liu Cun Li Xin Diao Yanhao Zhang Xiuli Su Yuanyuan Song Guodong Cao Li Zhong Pui Wang Xiaojuan Liu Bobo Wing-Yee Mok Shusheng Zhang Dong-Yan Jin Jie Zhou Honglin Chen Zongwei Cai | 2024 | Science China(Life Sciences)2024，67，1： | 0 |
| 7 | Isotopic evidence for volatile replenishment of the Moon during the Late Accretion显示文摘The traditional view of a dry,volatile-poor Moon has been challenged by the identification of water and other volatiles in lunar samples,but the volatile budget delivery time(s),source(s)and temporal evolution remain poorly constrained.Here we show that hydrogen and chlorine isotopic ratios in lunar apatite changed significantly during the Late Accretion(LA,4.1-3.8 billion years ago).During this period,deuterium/hydrogen ratios in the Moon changed from initial carbonaceous-chondrite-like values to values consistent with an influx of ordinary-chondrite-like material and pre-LA elevatedδ^37C1 values drop towards lower chondrite-like values.Inferred pre-LA lunar interior water contents are significantly lower than pristine values suggesting degassing,followed by an increase during the LA.These trends are consistent with dynamic models of solar-system evolution,suggesting that the Moon’s(and Earth’s)initial volatiles were replenished〜0.5 Ga after their formation,with their final budgets reflecting a mixture of sources and delivery times. | Yanhao Lin Wim van Westrenen | 2019 | National Science Review2019，6，6： | 0 |
| 8 | A novel rapid cooling assembly design in a high-pressure cubic press apparatus显示文摘In traditional high-pressure–temperature assembly design, priority has been given to temperature insulation and retention at high pressures.This limits the efficiency of cooling of samples at the end of experiments, with a negative impact on many studies in high-pressure Earth andplanetary science. Inefficient cooling of experiments containing molten phases at high temperature leads to the formation of quench textures,which makes it impossible to quantify key compositional parameters of the original molten phase, such as their volatile contents. Here,we present a new low-cost experimental assembly for rapid cooling in a six-anvil cubic press. This assembly not only retains high heatingefficiency and thermal insulation, but also enables a very high cooling rate (∼600 ℃/s from 1900 ℃ to the glass transition temperature).Without using expensive materials or external modification of the press, the cooling rate in an assembly (∼600 ℃/s) with cube lengths of38.5 mm is about ten times faster than that in the traditional assembly (∼60 ℃/s). Experiments yielding inhomogeneous quenched melttextures when the traditional assembly is used are shown to yield homogeneous silicate glass without quench textures when the rapid coolingassembly is used. | Peiyan Wu Yongjiang Xu Yanhao Lin | 2024 | Matter and Radiation at Extremes2024，9，2： | 0 |
| 9 | Dense hydrous silica carrying water to the deep Earth and promotion of oxygen fugacity heterogeneity显示文摘Water has remarkable effects on the properties of mantle rocks,but,owing to the high temperatures in the mantle,uncertainties remain about how and how much water is transported into the deep Earth.Recent studies have shown that stishovite and post-stishovites as highpressure phases of SiO2 have the potential to carry weight percent levels of water into the Earth’s interior along the geotherm of the subducting oceanic crust.As slabs are subducted to the deepest mantle,dehydration of these dense hydrous silica phases has the potential to change the physicochemical properties of the mantle by reducing melting points,forming new high-pressure phases,and enhancing the oxygen fugacity heterogeneity of the lower mantle. | Yanhao Lin Ho-Kwang Mao | 2022 | Matter and Radiation at Extremes2022，7，6： | 0 |
| 10 | WaveLines:towards effective visualization and analysis of stability in power grid simulation显示文摘Closely related to the safety and stability of power grids,stability analysis has long been a core topic in the electric industry.Conventional approaches employ computational simulation to make the quantitative judgement of the grid stability under distinctive conditions.The lack of in-depth data analysis tools has led to the difficulty in analytical tasks such as situation-aware analysis,instability reasoning and pattern recognition.To facilitate visual exploration and reasoning on the simulation data,we introduce WaveLines,a visual analysis approach which supports the supervisory control of multivariate simulation time series of power grids.We design and implement an interactive system that supports a set of analytical tasks proposed by domain experts and experienced operators.Experiments have been conducted with domain experts to illustrate the usability and effectiveness of WaveLines. | Tianye ZHANG Qi WANG Liwen LIN Jiazhi XIA Xiwang XU Yanhao HUANG Xiaonan LUO Wenting ZHENG Wei CHEN | 2021 | Frontiers of Computer Science2021，15，6： | 0 |
