The growth of dendrites in the lithium(Li)metal anode hinders the commercialization of lithium metal batteries(LMBs).Electrolyte additives have proved to be an effective way to solve the problem of dendrites and improve the coulombic efficiency.Herein,we propose a strategy of using L-tyrosine(L-Tyr)as an additive to protect the lithium metal anode in situ,where L-Tyr can be electropolymerized in situ to form an ordered array of nanosheets on the surface of the lithium metal anode to uniformly deposit lithium ions.At the same time,the addition of L-Tyr changed the structure of the solvent in the electrolyte,because the carboxyl group on L-Tyr make DME form hydrogen bonds easily.Besides,the reduction of free DME makes more TFSI-involved in the formation of the SEI film on the electrode surface,which increases the proportion of LiF in the SEI film.With 2 wt%L-Tyr,Li||Li symmetric cells superior cycle stability in ether electrolytes,Li|Cu cells y improved stability up to 200 cycles with an average CE of 93.1%in ether electrolytes and Li||Li_(4)Ti_(5)O_(12)(LTO)demonstrated an excellent cycling capabilitie with 119 mAh/g capacity retention by the 5000^(th)cycle.

Background and aim:Hepatitis C virus(HCV)infection is one of the major global health challenges,leading to a significant increase in rates of hepatic fibrosis,cirrhosis and hepatocellular carcinoma.A comprehensive nationwide survey of trends in prevalence and associated factors could facilitate pre-ventive behavioral interventions.Herein,we sought to determine prevalence,diagnosis,treatment,and risk factors for HCV infection in the general United States(US)population.Methods:This was a secondary analysis of the publicly available data from the US National Health and Nutrition Examination Survey(NHANES).The prevalence of HCV-RNA-positive(HCV-RNAþ)was weighted using patient serum sample data collected from 1999 to 2018.A propensity score matching model was used due to the imbalance in the number of HCV-RNAþand HCV-RNA-negative(HCV-RNA?)patients.Matched variables included gender,age,educational level,marital status,language,household size,alcohol consumption,smoking,number of family members and family income to poverty ratio.Results:The weighted prevalence of HCV-RNAþwas 1.11%(95%confidence interval(CI):1.02e1.20),1.58%(95%CI:1.42e1.74)for men and 0.67%(95%CI:0.57e0.77)for women aged 20 years or older in the US from 1999 to 2018.The weighted prevalence of HCV-RNAþincreased from 0.87%(95%CI:0.62e1.12)in 2013e2014,0.95%(95%CI:0.68e1.22)in 2015e2016 to 1.00%(95%CI:0.72e1.28)in 2017e2018,respectively.In propensity-matched analysis,patients with HCV-RNAþwere more likely to be non-Hispanic black,and have had drug use and blood transfusions.Meanwhile,the weighted diagnostic and treatment rates were 56.27%(95%CI:50.90e61.64)and 35.40%(95%CI:27.64e43.16)from 1999 to 2018,respectively.Conclusions:Active HCV infection rate increased between 2013 and 2018,varied by demographic and risk variables.In the direct-acting antiviral era,affordable treatment and universal screening have the potential to improve overall national health.

Sulfide solid electrolyte(SE)is one of the most promising technologies for all-solid-state batteries(ASSBs)because of its high ionic conductivity and ductile mechanical properties.In order to further improve the energy density of sulfide-based ASSBs and promote practical applications,silicon anodes with ultrahigh theoretical capacity(4,200 mAh·g^(−1))and rich resource abundance have broad commercial prospects.However,significant challenges including bulk instability of sulfide SEs and poor utilization of silicon materials have severely impeded the ASSBs from becoming viable.In this review,we first introduce the critical bulk properties of sulfide SEs and the most recent improving strategies covering the ionic conductivity,air stability,electrochemical window,mechanical stability,thermostability and solvent stability.Next,we introduce the main factors affecting the compatibility of silicon and sulfide SE,including the carbon’s effect,particle size of silicon,external pressure,silicon composite matrix and the depth of silicon’s lithiation.Finally,we discuss possible research directions in the future.We hope that this review can provide a comprehensive picture of the role of nanoscale approaches in recent advances in ASSBs with sulfide and silicon,as well as a source of inspiration for future research.

Photocatalytic conversion of CO_(2)into solar fuels provides a bright route for the green and sustainable development of human society.However,the realization of efficient photocatalytic CO_(2)reduction reaction(CO_(2)RR)is still challenging owing to the sluggish kinetics or unfavorable thermodynamics for basic chemical processes of CO_(2)RR,such as adsorption,activation,conversion and product desorption.To overcome these shortcomings,recent works have demonstrated that surface engineering of semiconductors,such as introducing surface vacancy,surface doping,and cocatalyst loading,serves as effective or promising strategies for improved photocatalytic CO_(2)RR with high activity and selectivity.The essential reason lies in the activation and reaction pathways can be optimized and regulated through the reconstruction of surface atomic and electronic structures.Herein,in this review,we focus on recent research advances about rational design of semiconductor surface for photocatalytic CO_(2)RR.The surface engineering strategies for improved CO_(2)adsorption,activation,and product selectivity will be reviewed.In addition,theoretical calculations along with in situ characterization techniques will be in the spotlight to clarify the kinetics and thermodynamics of the reaction process.The aim of this review is to provide deep understanding and rational guidance on the design of semiconductors for photocatalytic CO_(2)RR.

To reveal the resonance suppression mechanism of the blood circulation in dragonfly wings,a numerical modeling method of dragonfly wings based on Voronoi diagrams is proposed,and the changes in mass,aerodynamic damping,and natural frequencies caused by blood circulation in veins are investigated.The equivalent mass of blood,boundary conditions,and aerodynamic damping are calculated theoretically.Modal analysis and harmonic response analysis of wing models with different blood circulation paths are performed using the finite-element method(FEM).The vibration reduction ratioδis introduced to compare the damping efficiency of different mass regions.Finally,a natural frequency testing device is constructed to measure the natural frequencies of dragonfly wings.The results indicate that the shape,mass,and natural frequencies of the dragonfly wing model constructed by numerical method agree well with reality.The mass distribution on the wing can be altered by blood circulation,thereby adjusting the natural frequencies and achieving resonance suppression.The highestδof 1.013 is observed in the C region when blood circulates solely in secondary veins,but it is still lower than theδof 1.017 when blood circulates in complete veins.The aerodynamic damping ratio(1.19–1.79%)should not be neglected in the vibration analysis of the beating wing.
