| 1 | A single mutation underlying phenotypic convergence for hypoxia adaptation on the Qinghai-Tibetan Plateau显示文摘Dear Editor,The Qinghai-Tibet Plateau(QTP)is the highest and largest plateau in the world;its altitude exceeds 4500 m on average,posing great physiological challenges such as severe hypoxia for endemic wild mammals on the plateau.1 To cope with such a harsh environment,the phylogenetically distant QTP endemic mammals have independently evolved similar morphological and physiological traits. | Donqming Xu Cuiping Yang Qiushuo Shen Shengkai Pan Zhen Liu Tongzuo Zhang Xin Zhou Menglong Lei Peng Chen Hui Yang Tao Zhang Yuanting Guo Xiangjiang Zhan Yongbin Chen Peng Shi | 2021 | Cell Research2021，31，9： | 1 |
| 2 | Interfacial engineering of 3D hollow CoSe_(2)@ultrathin MoSe_(2)core@shell heterostructure for efficient pH-universal hydrogen evolution reaction显示文摘Rational design and construction of low-cost and highly efficient electrocatalysts for hydrogen evolution reaction(HER)is meaningful but challenging.Herein,a robust three dimensional(3D)hollow CoSe_(2)@ultrathin MoSe_(2)core@shell heterostructure(CoSe_(2)@MoSe_(2))is proposed as an efficient HER electrocatalyst through interfacial engineering.Benefitting from the abundant heterogeneous interfaces on CoSe_(2)@MoSe_(2),the exposed edge active sites are maximized and the charge transfer at the hetero-interfaces is accelerated,thus facilitating the HER kinetics.It exhibits remarkable performance in pH-universal conditions.Notably,it only needs an overpotential(η10)of 108 mV to reach a current density of 10 mA·cm^(-2)in 1.0 M KOH,outperforming most of the reported transition metal selenides electrocatalysts.Density functional theory(DFT)calculations unveil that the heterointerfaces synergistically optimize the Gibbs free energies of H2O and H^(*)during alkaline HER,accelerating the reaction kinetics.The present work may provide new construction guidance for rational design of high-efficient electrocatalysts. | Lili Zhang Yuanting Lei Danni Zhou Chengli Xiong Zhuoli Jiang Xinyuan Li Huishan Shang Yafei Zhao Wenxing Chen Bing Zhang | 2022 | Nano Research2022，15，4： | 1 |
| 3 | Carbon-supported high-entropy Co-Zn-Cd-Cu-Mn sulfide nanoarrays promise high-performance overall water splitting显示文摘Transition metal sulfides with homogeneous multi-metallic elements promise high catalytic performance for water electrolysis owing to the unique structure and highly tailorable electrochemical property.Most existing synthetic routes require high temperature to ensure the uniform mixing of various elements,making the synthesis highly challenging.Here,for the first-time novel carbon fiber supported high-entropy Co-Zn-Cd-Cu-Mn sulfide(CoZnCdCuMnS@CF)nanoarrays are fabricated by the mild cation exchange strategy.Benefiting from the synergistic effect among multiple metals and the strong interfacial bonding between high-entropy Co-Zn-Cd-Cu-Mn sulfide nanoarrays and the carbon fiber support,CoZnCdCuMnS@CF exhibits superior catalytic activity and stability toward overall water splitting in alkaline medium.Impressively,CoZnCdCuMnS@CF only needs low overpotentials of 173 and 220 mV to reach the current density of 10 mA•cm^(−2),with excellent durability for over 70 and 113 h for hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)respectively.More importantly,the bifunctional electrode(CoZnCdCuMnS@CF||CoZnCdCuMnS@CF)for overall water splitting can deliver a small cell voltage of 1.63 V to afford 10 mA•cm^(−2) and exhibit outstanding stability of negligible decay after 73 h continuous operation.This work provides a viable synthesis route toward advanced high-entropy materials with great potential applications. | Yuanting Lei Lili Zhang Wenjing Xu Chengli Xiong Wenxing Chen Xu Xiang Bing Zhang Huishan Shang | 2022 | Nano Research2022，15，7： | 0 |
| 4 | Toxicity effects of disinfection byproduct chloroacetic acid to Microcystis aeruginosa: Cytotoxicity and mechanisms显示文摘Chlorine-based disinfectants are widely used for disinfection in wastewater treatment.The mechanism of the effects of chlorinated disinfection by-products on cyanobacteria was unclear.Herein,the physiological effects of chloroacetic acid(CAA)on Microcystis aeruginosa(M.aeruginosa),including acute toxicity,oxidative stress,apoptosis,production of microcystin-LR(MC-LR),and the microcystin transportation-related gene mcyH transcript abundance have been investigated.CAA exposure resulted in a significant change in the cell ultrastructure,including thylakoid damage,disappearance of nucleoid,production of gas vacuoles,increase in starch granule,accumulation of lipid droplets,and disruption of cytoplasm membranes.Meanwhile,the apoptosis rate of M.aeruginosa increased with CAA concentration.The production of MC-LR was affected by CAA,and the transcript abundance of mcyH decreased.Our results suggested that CAA poses acute toxicity to M.aeruginosa,and it could cause oxidative damage,stimulate MC-LR production,and damage cell ultrastructure.This study may provide information about the minimum concentration of CAA in the water environment,which is safe for aquatic organisms,especially during the global coronavirus disease 2019 pandemic period. | Jing Ye Jiawei Ni Fuxiang Tian Xiyan Ji Meifang Hou Yuanting Li Lei Yang Runxiang Wang Wenwu Xu Liang Meng | 2023 | Journal of Environmental Sciences2023，，7： | 0 |
