| 1 | Nanostructured Anode Materials for Non-aqueous Lithium Ion Hybrid Capacitors显示文摘The rapid advancement in electronic devices,electric vehicles,and grid storage stations have lead to a high demand for energy storage devices with enhanced power and energy densities as well as extended lifespans.Lithium ion hybrid capacitors are constructed with battery-type anodes and capacitor-type cathodes,which enables the direct integration of the high energy from lithium ion batteries and high power and long lifetime from supercapacitors,making lithium ion hybrid capacitor one of the most promising energy storage devices.In the past two decades,tremendous efforts have been put into the search for suitable battery-type anode materials with improved Faradaic reaction kinetics so that it can match with the fast non-Faradaic charging rate of the capacitive cathodes.This review aims to provide an up-to-date and comprehensive summary of the battery-type anode materials for high-performance lithium ion hybrid capacitors.To date,a large variety of battery-type anode materials have been explored with smart material design strategies,such as carbonaceous materials,metal oxides,alloys,sulfides,nitirdes,and Mxenes,etc.,which will be discussed in detail.A perspective to the challenges and future developing trends of lithium ion hybrid capacitors is proposed to close. | Cuiping Han Hongfei Li Ruiying Shi Lei Xu Junqin Li Feiyu Kang Baohua Li | 2018 | Energy & Environmental Materials2018,1,2: | 3 |
| 2 | Overview of lethal human coronaviruses显示文摘Coronavirus infections of multiple origins have spread to date worldwide,causing severe respiratory diseases.Seven coronaviruses that infect humans have been identified:HCoV-229E,HCoV-OC43,HCoV-NL63,HCoV-HKU1,SARS-CoV,MERS-CoV,and SARS-CoV-2.Among them,SARS-CoV and MERS-CoV caused outbreaks in 2002 and 2012,respectively.SARS-CoV-2(COVID-19)is the most recently discovered.It has created a severe worldwide outbreak beginning in late 2019,leading to date to over 4 million cases globally.Viruses are genetically simple,yet highly diverse.However,the recent outbreaks of SARS-CoV and MERS-CoV,and the ongoing outbreak of SARS-CoV-2,indicate that there remains a long way to go to identify and develop specific therapeutic treatments.Only after gaining a better understanding of their pathogenic mechanisms can we minimize viral pandemics.This paper mainly focuses on SARS-CoV,MERS-CoV,and SARS-CoV-2.Here,recent studies are summarized and reviewed,with a focus on virus–host interactions,vaccine-based and drug-targeted therapies,and the development of new approaches for clinical diagnosis and treatment. | Bin Chen Er-Kang Tian Bin He Lejin Tian Ruiying Han Shuangwen Wang Qianrong Xiang Shu Zhang Toufic El Arnaout Wei Cheng | 2020 | Signal Transduction and Targeted Therapy2020,5,1: | 0 |
| 3 | Development of the high-strength ductile ferritic alloys via regulating the intragranular and grain boundary precipitation of G-phase显示文摘A typical G-phase strengthened ferritic model alloy(1Ti:Fe-20Cr-3Ni-1Ti-3Si,wt.%)has been carefully studied using both advanced experimental(EBSD,TEM and APT)and theoretical(DFT)techniques.During the classic“solid solution and aging”process,the superfine(Fe,Ni)_(2)TiSi-L2_(1)particles densely precipitate within the ferritic grain and subsequently transform into the(Ni,Fe)_(16)Ti_(6)Si_(7)-G phase.In the meanwhile,the elemental segregation at grain boundaries and the resulting precipitation of a large amount of the(Ni,Fe)_(16)Ti_(6)Si_(7)-G phase are also observed.These nanoscale microstructural evolutions result in a remarkable increase in hardness(100-300 HV)and severe embrittlement.When the“cold rolling and aging”process is used,the brittle fracture is effectively suppressed without loss of nano-precipitation strengthening ef-fect.Superhigh yield strength of 1700 MPa with 4%elongation at break is achieved.This key improvement in mechanical properties is mainly attributed to the pre-cold rolling process which effectively avoids the dense precipitation of the G-phase at the grain boundary.These findings could shed light on the further exploration of the precipitation site via optimal processing strategies. | Mujin Yang Chao Huang Jiajia Han Haichen Wu Yilu Zhao Tao Yang Shenbao Jin Chenglei Wang Zhou Li Ruiying Shu Cuiping Wang Huanming Lu Gang Sha Xingjun Liu | 2023 | Journal of Materials Science & Technology2023,,5: | 0 |
