Lithium(Li)metal electrodes show significantly different reversibility in the electrolytes with different salts.However,the understanding on how the salts impact on the Li loss remains unclear.Herein,using the electrolytes with different salts(e.g.,lithium hexafluorophosphate(LiPF_(6)),lithium difluoro(oxalato)borate(LiDFOB),and lithium bis(fluorosulfonyl)amide(LiFSI))as examples,we decouple the irreversible Li loss(SEI Li^(+)and“dead”Li)during cycling.It is found that the accumulation of both SEI Li^(+)and“dead”Li may be responsible to the irreversible Li loss for the Li metal in the electrolyte with LiPF_(6)salt.While for the electrolytes with LiDFOB and LiFSI salts,the accumulation of“dead”Li predominates the Li loss.We also demonstrate that lithium nitrate and fluoroethylene carbonate additives could,respectively,function as the“dead”Li and SEI Li^(+)inhibitors.Inspired by the above understandings,we propose a universal procedure for the electrolyte design of Li metal batteries(LMBs):(i)decouple and find the main reason for the irreversible Li loss;(ii)add the corresponding electrolyte additive.With such a Li-loss-targeted strategy,the Li reversibility was significantly enhanced in the electrolytes with 1,2-dimethoxyethane,triethyl phosphate,and tetrahydrofuran solvents.Our strategy may broaden the scope of electrolyte design toward practical LMBs.

A long-life and safe lithiated graphite-selenium cell with competitive gravimetric and volumetric energy densities

Journal of Energy Chemistry 2021年第9期30卷 556-563页

作者： Xiaoqun Qi Qiang Jin Fengyi Yang ruining jiang Quan Sun Long Qie Yunhui Huang Institute of New Energy for Vehicles School of Materials Science and EngineeringTongji UniversityShanghai 201804China

Lithium-selenium(Li-Se) battery is a promising system with high theoretical gravimetric and volumetric energy densities, while its long-term cyclability is hard to realize, especially when a practical Se cathode with high Se content, high Se loading, and high density is employed. The main obstacles are the sluggish conversion kinetics of the dense Se cathodes and the continuous deterioration of the Li-metal anodes.Here, by introducing an acetonitrile(AN)-based electrolyte and replacing the Li electrode with a lithiated graphite, we successfully build a hybrid conversion-intercalation system using a high-content(80 wt%),decent-loading(3.0 mg cm^(-2)), and low-porosity(44%) Se cathode. The as-designed lithiated graphite||Se(LG||Se) cell demonstrated a high Se utilization(97.4%), a long cycle life(3000 cycles), and an ultrahigh average Coulombic efficiency(99.98%). The cell also works well under lean-electrolyte(2 l L mg^(-1)) condition and shows outstanding safety performance in the nail-penetrating test. The combination affords the competitive comprehensive performances, including high volumetric and gravimetric energy densities, long cycling life, and superb safety of the LG||Se cell. In addition, with a newly-designed threeelectrode pouch cell, the lithiation of the graphite anodes could be done with an in-situ lithiation process,indicating the high potential of the as-proposed LG||Se cell for the practical applications.

Esterification of acetic acid with isobutanol catalyzed by ionic liquid n-sulfopropyl-3-methylpyridinium trifluoromethanesulfonate:Experimental and kinetic study

As an important organic,isobutyl acetate(IbAc)has been widely used in industries because of its good biodegradability,low surface tension,and other properties.The industrial production of IbAc is usually catalyzed by sulfuric acid.However,the use of sulfuric acid has the drawbacks of causing considerable corrosion to equipment and being difficult to be separated.In this work,n-sulfopropyl-3-methylpyridinium trifluoromethanesulfonate([HSO_(3)-PMPY][CF_(3)SO_(3)])Bronsted acidic ionic liquid(BAIL)was used as the catalyst and the catalytic activity,solubility,and corrosiveness were evaluated for the esterification of acetic acid with isobutanol.The reaction kinetics and chemical equilibrium were systemically studied.Compared to conventional acid catalysts,[HSO_(3)-PMPY][CF_(3)SO_(3)]showed higher catalytic activity,more excellent reusability,more favorable phase separation,and non-corrosiveness.Three kinetic equations based on ideal homogeneous(IH),non-ideal homogeneous(NIH),and modified nonideal homogeneous(NIH-M)models were established and correlated with the experimental data to determine the parameters and errors.The NIH-M model exhibited the best agreement with the experimental data,owing to its prediction considering the non-ideality and the self-catalysis effect of acetic acid in this system.Besides,the error of NIH-M model fitting was mainly caused by the difference in solubility between[HSO_(3)-PMPY][CF_(3)SO_(3)]with reactants and products in the reaction system.Furthermore,the applicability of the NIH-M model was investigated by simulating the esterification of acetic acid with three short-chain alcohols(ethanol,n-butanol,and isobutanol)catalyzed by BAILs.The NIH-M model displayed an acceptable simulation for this type of acetic acid esterification reaction catalyzed by BAILs at different ranges of the BAILs concentration and temperature.This study confirmed the industrial prospects of[HSO_(3)-PMPY][CF_(3)SO_(3)]in isobutyl acetate production and the applicability of the NIH-M kinetic model in the esterif

Folate receptor alpha(FOLR1)is vital for cells ingesting folate(FA).FA plays an indispensable role in cell pro-liferation and survival.However,it is not clear whether the axis of FOLR1/FA has a similar function in viral replication.In this study,we used vesicular stomatitis virus(VSV)to investigate the relationship between FOLR1-mediated FA deficiency and viral replication,as well as the underlying mechanisms.We discovered that FOLR1 upregulation led to the deficiency of FA in HeLa cells and mice.Meanwhile,VSV replication was notably sup-pressed by FOLR1 overexpression,and this antiviral activity was related to FA deficiency.Mechanistically,FA deficiency mainly upregulated apolipoprotein B mRNA editing enzyme catalytic subunit 3B(APOBEC3B)expression,which suppressed VSV replication in vitro and in vivo.In addition,methotrexate(MTX),an FA metabolism inhibitor,effectively inhibited VSV replication by enhancing the expression of APOBEC3B in vitro and in vivo.Overall,our present study provided a new perspective for the role of FA metabolism in viral infections and highlights the potential of MTX as a broad-spectrum antiviral agent against RNA viruses.

Background:The coronavirus disease 2019(COVID-19)has affected approximately 2 million individuals worldwide;however,data regarding fatal cases have been limited.Objective:To report the clinical features of 162 fatal cases of COVID-19 from 5 hospitals in Wuhan between December 30,2019 and March 12,2020.Methods:The demographic data,signs and symptoms,clinical course,comorbidities,laboratory findings,computed tomographic(CT)scans,treatments,and complications of the patients with fatal cases were retrieved from electronic medical records.Results:The median patient age was 69.5(interquartile range:63.0–77.25)years,and 80%of the patients were over 61 years.A total of 112(69.1%)patients were men.Hypertension(45.1%)was the most common comorbidity,while 59(36.4%)patients had no comorbidity.At admission,131(81.9%)patients had severe or critical COVID-19,whereas 39(18.1%)patients with hypertension or chronic lung disease had moderate COVID-19.In total,126(77.8%)patients received antiviral treatment,while 132(81.5%)patients received glucocorticoid treatment.A total of 116(71.6%)patients were admitted to the intensive care unit(ICU),and 137(85.1%)patients received mechanical ventilation.Most patients received mechanical ventilation before ICU admission.Approximately 93.2%of the patients developed respiratory failure or acute respiratory distress syndrome.There were no significant differences in the inhospital survival time among the hospitals(P=0.14).Conclusion:Young patients with moderate COVID-19 without comorbidity at admission could also develop fatal outcomes.The in-hospital survival time of the fatal cases was similar among the hospitals of different levels in Wuhan.

儿茶素是一种酚类化合物,具有抗过敏、抗氧化、抗炎和抗菌等多种功效,对人体健康有诸多益处。但由于儿茶素热稳定性差、生物利用率较低,膳食摄入的碳水化合物、蛋白质、脂质等物质易与儿茶素在胃肠道中发生相互作用,影响儿茶素的吸收、分布、代谢和排泄过程,进而影响其生物利用率和生理活性。此外,当两种或多种天然多酚类化合物联合应用时可能会产生协同增效作用,可以抑制食品生产加工污染物、降脂减肥、降血糖、抗炎抗菌等。因此,本文主要对膳食成分对儿茶素生物利用率的影响进行综述,阐明了儿茶素和膳食多酚相互作用的机制和两者在协同增效方面的应用前景。
