1A review on the critical challenges and progress of SiO_(x)-based anodes for lithium-ion batteries显示文摘With the advantages of abundant resources,high specific capacity,and relatively stable cycling performance,silicon suboxides(SiO_(x) ,x<2)have been recently suggested as promising anodes for next-generation lithium-ion batteries(LIBs).SiO_(x) exhibits superior storage capability because of the presence of silicon and smaller volume change upon charge/discharge than Si owing to the buffering effect of the initial lithiation products of inert lithium oxide and lithium silicates,enabling a stable cycle life of electrodes.However,significant improvements such as overcoming issues related to volume changes in cycling and initial irreversible capacity loss and enhancing the ionic and electronic charge transport in poorly conducting SiO_(x) electrodes,are still needed to achieve the satisfactory performance required for commercial applications.This review summarizes recent progress on the cycling performance and initial coulombic efficiency of SiO_(x) .Advances in the design of particle morphology and composite composition,prelithiation and prereduction methods,and usage of electrolyte additives and optimized electrode binders are discussed.Perspectives on the promising research directions that might lead to further improvement of the electrochemical properties of SiO_(x) -based anodes are noted.This paper can serve as a basis for the research and development of high-energy-density LIBs.Nana Yao Yu Zhang Xianhui Rao Zhao Yang Kun Zheng KonradŚwierczek Hailei Zhao 2022International Journal of Minerals,Metallurgy and Materials2022,29,4:4

3Mechanism underlying the protective effect of Kaixin Jieyu Fang on vascular depression following cerebral white matter damage显示文摘The Chinese compound Kaixin Jieyu Fang can be used to treat vascular depression;however,the underlying mechanism remains unclear.This study established a rat model of chronic cerebral ischemia-caused white matter damage by ligation of the bilateral common carotid arteries.Rats received daily intragastric administration of a suspension of Kaixin Jieyu Fang powder.After 3,7and 21 days of treatment,the degree of white matter damage in the cerebral ischemia rat model was alleviated,Bcl-2 protein and mRNA expression in brain tissue increased,and Bax protein and mRNA expression decreased.These results indicate that Kaixin Jieyu Fang can alleviate cerebral white matter damage,and the underlying mechanism is associated with regulation of Bcl-2/Bax protein and mRNA expression,which is one of possible mechanism behind the protective effect of Kaixin Jieyu Fang against vascular depression.Ying Zhang Shijing Huang Yanyun Wang Junhua Pan Jun Zheng Xianhui Zhang Yuxia Chen Duojiao Li 2014Neural Regeneration Research2014,9,1:4
4Oncoprotein HBXIP promotes tumorigenesis through MAPK/ERK pathway activation in non-small cell lung cancer显示文摘Objective:The oncoprotein,hepatitis B X-interacting protein(HBXIP),has been reported to play an important role in human malignancies.However,its functions in non-small cell lung cancer(NSCLC)are poorly understood.The goal of the present study was to identify the role of HBXIP in the regulation of NSCLC development.Methods:The level of HBXIP expression in NSCLC tissue was assessed by immunohistochemical and Western blot analyses,and its relationships with clinicopathological features and outcomes were statistically evaluated.The effects of HBXIP on NSCLC cell progression were assessed through cell viability,colony formation,and flow cytometry analyses in vitro.The mechanism by which HBXIP regulated the MAPK pathway was studied by Western blot,immunofluorescence,and immunoprecipitation assays.In addition,in vivo experiments were performed to evaluate the progression of NSCLC and ERK signaling pathway activation after HBXIP knockdown.Results:HBXIP was overexpressed in human NSCLC and was correlated with the invasiveness of NSCLC.The high expression of HBXIP in NSCLC was significantly correlated with gender(P=0.033),N stage(P=0.002),and tumor-node-metastasis stage(P=0.008).In vitro experiments using an NSCLC cell line revealed that HBXIP knockdown resulted in the suppression of cell proliferation and colony formation,which was consistent with the enhanced cell cycle arrest in G1 phase.The results of a mechanistic investigation suggested that binding of HBXIP to MEK1 protein promoted MAPK/ERK signaling pathway activation in NSCLC by preventing the proteasome-mediated degradation of MEK1.In addition,the results obtained using in vivo subcutaneous tumor xenografts confirmed that HBXIP deficiency decreased MEK1 protein levels and NSCLC tumor growth.Conclusions:Taken together,our results showed that the HBXIP-MEK interaction promoted oncogenesis via the MAPK/ERK pathway,which may serve as a novel therapeutic target for cancers in which MAPK/ERK signaling is a dominant feature.Jun Zhang Bei Sun Xianhui Ruan Xiukun Hou Jingtai Zhi Xiangrui Meng Xiangqian Zheng Ming Gao 2021Cancer Biology & Medicine2021,18,1:3
5Orbital ordering and fluctuations in a kagome superconductor CsV_(3)Sb_(5)显示文摘Recently,competing electronic instabilities,including superconductivity and density-wave-like order,have been discovered in vanadium-based kagome metals AV_(3)Sb_(5)(A=K,Rb,Cs)with a nontrivial band topology.This finding stimulates considerable interest to study the interplay of these competing electronic orders and possible exotic excitations in the superconducting state.Here,we performed51V and133Cs nuclear magnetic resonance(NMR)measurements on a CsV_(3)Sb_(5)single crystal to clarify the nature of density-wave-like transition in these kagome superconductors.A first-order structural transition is unambiguously revealed below T_(s)~94 K by observing the sudden splitting of Knight shift in^(51)V NMR spectrum.Moreover,combined with^(133)Cs NMR spectrum,the present result confirms a three-dimensional structural modulation.By further analyzing the anisotropy of Knight shift and 1/T_(1)T at^(51)V nuclei,we proposed that the orbital order is the primary electronic order induced by the firstorder structural transition,which is supported by further analysis on electric field gradient at^(51)V nuclei.In addition,the evidence for possible orbital fluctuations is also revealed above T_(s).The present work sheds light on a rich orbital physics in kagome superconductors AV_(3)Sb_(5).DianWu Song LiXuan Zheng FangHang Yu Jian Li LinPeng Nie Min Shan Dan Zhao ShunJiao Li BaoLei Kang ZhiMian Wu YanBing Zhou KuangLv Sun Kai Liu XiGang Luo ZhenYu Wang JianJun Ying XianGang Wan Tao Wu XianHui Chen 2022Science China(Physics,Mechanics & Astronomy)2022,65,4:2
6National Cancer Data Linkage Platform of China:Design,Methods,and Application显示文摘Background:The National Cancer Center(NCC)and China CDC cooperatively designed a National Cancer Data Linkage(NCDL)Platform to fulfill the task of sharing cancer outcome data through an automatic web-based system.Methods:NCC and China CDC established a web-based NCDL Platform to link death information from China CDC with the cancer database from NCC.Overall,76,708 cancer patients’data were analyzed to assess the feasibility and match rate of the NCDL Platform for 7 major cancers.Results:The function of the platform includes a data application and approval system,data linkage module,and results visualization system.Through the platform,38.9%cases were identified as deaths cases from the NCDL Platform in the first 3 years after cancer diagnosis.The linkage rate was highest in liver cancer and lowest in breast cancer.Conclusions:The NCDL Platform provides a powerful and efficient way to link national vital statistics with national cancer programs’data.Expanding cancer outcome data linkage may not only improve data collection efficiency,but also improve data use.Hongmei Zeng Yunning Liu Lijun Wang Peng Yin Baohua Wang Ruiying Fu Xianhui Ran Rongshou Zheng Siwei Zhang Jiangmei Liu Jinling You Kexin Sun Shaoming Wang Li Li Ru Chen Wenqiang Wei Maigeng Zhou Jing Wu Jie He 2022China CDC weekly2022,4,13:1

8Chemical characterization and source identification of PM_(2.5) in Luoyang after the clean air actions显示文摘Luoyang is a typical heavy industrial city in China,with a coal-dominated energy structure and serious air pollution.Following the implementation of the clean air actions,the physic-ochemical characteristics and sources of PM_(2.5) have changed.A comprehensive study of PM_(2.5) was conducted from October 16,2019 to January 23,2020 to evaluate the effectiveness of previous control measures and further to provide theory basis for more effective policies in the future.Results showed that the aerosol pollution in Luoyang in autumn and win-ter is still serious with the average concentration of 91.1 μg/m^(3),although a large reduction(46.9%)since 2014.With the contribution of nitrate increased from 12.5%to 25.1%and sul-fate decreased from 16.7%to 11.2%,aerosol pollution has changed from sulfate-dominate to nitrate-dominate.High NO_(3)^(-)/SO_(4)^(2-)ratio and the increasing of NO_(3)^(-)/SO_(4)^(2-)ratio with the aggravation of pollution indicating vehicle exhaust playing an increasingly important role in PM_(2.5) pollution in Luoyang,especially in the haze processes.Secondary inorganic ions contributed significantly to the enhancement of PM_(2.5) during the pollution period.The high value of Cl^(-)/Na^(+)and EC concentration indicate coal combustion in Luoyang is still serious.The top three contributor sources were secondary inorganic aerosols(33.3%),coal combus-tion(13.6%),and industrial emissions(13.4%).Close-range transport from the western and northeastern directions were more important factors in air pollution in Luoyang during the sampling period.It is necessary to strengthen the control of coal combustion and reduce vehicle emissions in future policies.Min Xu Zirui Liu Bo Hu Guangxuan Yan Jianan Zou Shuman Zhao Jingxiang Zhou Xianhui Liu Xueping Zheng Xiaoyan Zhang Jing Cao Mengshuang Guan Yirong Lv Yanyun Zhang 2022Journal of Environmental Sciences2022,34,5:1

12Valence state of transition metal center as an activity descriptor for CO_(2) reduction on single atom catalysts显示文摘Carbon dioxide(CO_(2))catalytic reduction has been passionately pursued for a long period of time due to its special importance in alleviating the greenhouse effect as well as generating valuable fuels and chemicals[1].Among the various approaches for achieving CO_(2)conversion,considerable efforts have been devoted to electrochemical reduction of CO_(2)since this technology operates at ambient and mild environments and can potentially produce various useful products[2].Shisheng Zheng Changjian Zuo Xianhui Liang Shunning Li Feng Pan 2021Journal of Energy Chemistry2021,30,5:0
13Magnetic-field-induced electronic instability of Weyl-like fermions in compressed black phosphorus显示文摘Revealing the role of Coulomb interaction in topological semimetals with Dirac/Weyl-like band dispersion shapes a new frontier in condensed matter physics.Topological node-line semimetals(TNLSMs),anticipated as a fertile ground for exploring electronic correlation effects due to the anisotropy associated with their node-line structure,have recently attracted considerable attention.In this study,we report an experimental observation for correlation effects in TNLSMs realized by black phosphorus(BP)under hydrostatic pressure.By performing a combination of nuclear magnetic resonance measurements and band calculations on compressed BP,a magnetic-field-induced electronic instability of Weyl-like fermions is identified under an external magnetic field parallel to the so-called nodal ring in the reciprocal space.Anomalous spin fluctuations serving as the fingerprint of electronic instability are observed at low temperatures,and they are observed to maximize at approximately 1.0 GPa.This study presents compressed BP as a realistic material platform for exploring the rich physics in strongly coupled Weyl-like fermions.Lixuan Zheng Kaifa Luo Zeliang Sun Dan Zhao Jian Li Dianwu Song Shunjiao Li Baolei Kang Linpeng Nie Min Shan Zhimian Wu Yanbing Zhou Xi Dai Hongming Weng Rui Yu Tao Wu Xianhui Chen 2023Science China(Physics,Mechanics & Astronomy)2023,66,11:0
14Evolution of the newest diagnostic methods for COVID-19:a Chinese perspective显示文摘Coronavirus disease 2019(COVID-19)has continued to spread globally since late 2019,representing a formidable challenge to the world's healthcare systems,wreaking havoc,and spreading rapidly through human contact.With fever,fatigue,and a persistent dry cough being the hallmark symptoms,this disease threatened to destabilize the delicate balance of our global community.Rapid and accurate diagnosis of COVID-19 is a prerequisite for understanding the number of confirmed cases in the world or a region,and an important factor in epidemic assessment and the development of control measures.It also plays a crucial role in ensuring that patients receive the appropriate medical treatment,leading to optimal patient care.Reverse transcription-polymerase chain reaction(RT-PCR)technology is currently the most mature method for detecting viral nucleic acids,but it has many drawbacks.Meanwhile,a variety of COVID-19 detection methods,including molecular biological diagnostic,immunodiagnostic,imaging,and artificial intelligence methods have been developed and applied in clinical practice to meet diverse scenarios and needs.These methods can help clinicians diagnose and treat COVID-19 patients.This review describes the variety of such methods used in China,providing an important reference in the field of the clinical diagnosis of COVID-19.Mingtao LIU Jiali LYU Xianhui ZHENG Zhiman LIANG Baoying LEI Huihuang CHEN Yiyin MAI Huimin HUANG Baoqing SUN 2023Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023,24,6:0
15Flotation behaviors of chalcopyrite and galena using ferrate(Ⅵ) as a depressant显示文摘This paper investigated the effects of potassium ferrate(PF)on the flotation performances of chalcopyrite and galena.The flotation results showed that PF obviously depressed galena,but had little effects on the floatability of chalcopyrite within pH range of 4.0–12.0.Zeta potential tests showed that the addition of PF induced the formation of more amounts of hydrophilic species on the surface of galena under an alkaline environment.Industrial grade O-isopropyl-N-ethyl thionocarbamate(IPETC)chemically adsorbed on the surface of the PF-treated chalcopyrite and galena after its addition.Contact angle measurements showed that with the addition of PF,the contact angle of the galena surface significantly decreased compared with the chalcopyrite surface.Localized electrochemical impedance spectroscopy(LEIS)tests showed that the addition of PF increased the impedance of the galena surface.X-ray photoelectron spectroscopy(XPS)analyses revealed that the formation of hydrophilic species,namely lead sulfite,lead hydroxide and ferric hydroxide,on the galena surface,decreased its floatability in the presence of PF,while the formation of hydrophobic species,namely copper disulfide and elemental sulfur,on the chalcopyrite surface,maintained its floatability.Finally,a descriptive model for the reaction of PF with chalcopyrite and galena was proposed.Yongxing Zheng Yusong Huang Panjin Hu Xianhui Qiu Jinfang Lv Lingyun Bao 2023International Journal of Mining Science and Technology2023,33,1:0
16Multivalent Display of Lipophilic DNA Binders for Dual-Selective Anti-Mycobacterium Peptidomimetics with Binary Mechanism of Action显示文摘We made oligoamidine-based peptidomimetics highly specific for mycobacteria eradication by introducing and arraying lipophilic DNA binding motifs on macromolecular backbones.The short poly(amidino-phenylindole)(PAPI)structures feature an alternating amphiphilic structure with cationic,lipophilic DNA-binding moieties,enabling fast and selective eradication of mycobacteria through binary,membrane-and DNA-selective mechanisms of action.More importantly,PAPIs address the primary treatment challenge by combating mycobacteria in eukaryotic cells and working as a sensitizer for conventional antibiotics,in bothways promoting more thorough removal of pathogens and reducing the mycobacteria’s resistance generation rate during treatment.Structural optimizationwas achieved to counter specific pathogens,including Mycobacterium tuberculosis,in the Mycobacterium genus.One of the hit peptidomimetics was evaluated in a zebrafish-based aquatic infection model using Mycobacterium fortuitum and a mice tail infection model using Mycobacterium marinum,both revealing excellent in vivo performance.Jianxue Wang Junfeng Song Xianhui Chen Rey-Ting Guo Yingjie Wang Guopu Huang Nan Zheng Peilei Hu Xinxin Feng Yugang Bai 2022CCS Chemistry2022,4,11:0
17Li-rich channels as the material gene for facile lithium diffusion in halide solid electrolytes显示文摘Halide solid electrolytes have attracted intense research interest recently for application in all-solid-state lithiumion batteries. Herein, we present a systematic first-principles study of the Li3MX6 (M: multivalent cation;X:halogen anion) halide family that unveils the link between Li-rich channels and ionic conductivity, highlightingthe former as a material gene in these compounds. By screening a total of 180 halides for those with highthermodynamic stability, wide electrochemical window, low chemical reactivity, and decent Li-ion conductivity,we identify seven unexplored candidates for solid electrolytes. From these halides and another four prototypecompounds, we discover that the facile Li diffusion is rooted in the availability of diffusion pathways which canavoid direct connection with M cations-that is, where the local environment is Li-rich. These findings shed lighton strategies for regulating cation and anion frameworks to establish Li-rich channels in the design of high-performance inorganic solid electrolytes.Guohao Yang Xianhui Liang Shisheng Zheng Haibiao Chen Wentao Zhang Shunning Li Feng Pan 2022eScience2022,2,1:0
