1Issues and solutions toward zinc anode in aqueous zinc-ion batteries: A mini review显示文摘Aqueous zinc-ion batteries(ZIBs)have been intensively investigated as potential energy storage devices on account of their low cost,environmental benignity,and intrinsically safe merits.With the exploitation of highperformance cathode materials,electrolyte systems,and in-depth mechanism investigation,the electrochemical performances of ZIBs have been greatly enhanced.However,there are still some challenges that need to be overcome before its commercialization.Among them,the obstinate dendrites,corrosion,and hydrogen evolution reaction(HER)on Zn anodes are critical issues that severely limit the practical applications of ZIBs.To address these issues,various strategies have been proposed,and tremendous progress has been achieved in the past few years.In this article,we analyze the origins and effects of the dendrites,corrosion,and HER on Zn anodes in neutral and mildly acid aqueous solutions at first.And then,a scientific understanding of the fundamental design principles and strategies to suppress these problems are emphasized.Apart from these,this article also puts forward some requirements for the practical applications of Zn anodes as well as several cost-effectivemodifying strategies.Finally,perspectives on the future development of Zn anodes in aqueous solutions are also briefly anticipated.This article provides pertinent insights into the challenges on anodes for the development of highperformance ZIBs,which will greatly contribute to their practical applications.Chunlin Xie Yihu Li Qi Wang Dan Sun Yougen Tang Haiyan Wang 2020Carbon Energy2020,2,4:15
2Double-layer ramp-metering model for incident congestion on expressway显示文摘In order to ensure stable traffic capacity and avoid incident congestion,a double-layer ramp metering model is proposed in this paper,based on coordination control theory,to predict and control the traffic flow at each on-ramp,when there is incident congestion on the expressway.The function of the lower model is to recognize where the incident congestion exists,based on an adaptive neural network with inputs of traffic flow,velocity and density.The outputs of the lower model are the number of section where the congestion occurs,the number of ramp which should be controlled,and real-time traffic flow information.These outputs should be transmitted to the upper model.The function of the upper model is to design the ramp-metering strategy based on nonlinear theory.The outputs of the upper model are a ramp-metering rate and traffic-flow state after ramp controlling on the expressway.The results of the simulation show that the double-layer ramp metering model could shorten the delay by about 25%,and the variance of the model results is 0.002,which could certify the control strategy is equitable.Yihu Wu Dan Yu Wei Yu Tao Qin Yifen Li 2014Journal of Traffic and Transportation Engineering(English Edition)2014,1,2:7

4Phylotranscriptomic insights into Asteraceae diversity,polyploidy,and morphological innovation显示文摘Biodiversity is not evenly distributed among relatedgroups,raising questions about the factors con-tributing to such disparities.The sunflower family(Asteraceae,>26,000 species)is among the largestand most diverse plant families,but its species di-versity is concentrated in a few subfamilies,pro-viding an opportunity to study the factors affectingbiodiversity.Phylotranscriptomic analyses here of244 transcriptomes and genomes produced a phy-logeny with strong support for the monophyly ofAsteraceae and the monophyly of most subfamiliesand tribes.This phylogeny provides a reference fordetecting changes in diversification rates and pos-sible factors affecting Asteraceae diversity,whichinclude global climate shifts,whole‐genome dupli-cations(WGDs),and morphological evolution.Theorigin of Asteraceae was estimated at~83 Mya,with most subfamilies having diverged before theCretaceous–Paleocene boundary.Phylotran-scriptomic analyses supported the existence of 41WGDs in Asteraceae.Changes to herbaceousnessand capitulescence with multipleflower‐like capitula,often with distinctflorets and scaly pappus/re-ceptacular bracts,are associated with multiple up-shifts in diversification rate.WGDs might have con-tributed to the survival of early Asteraceae byproviding new genetic materials to support mor-phological transitions.The resulting competitive ad-vantage for adapting to different niches would haveincreased biodiversity in Asteraceae.Caifei Zhang Chien‐Hsun Huang Mian Liu YiHu Jose L.Panero Federico Luebert Tiangang Gao Hong Ma 2021Journal of Integrative Plant Biology2021,63,7:4

6The thermodynamics analysis and experimental validation for complicated systems in CO_2 hydrogenation process显示文摘Catalytic conversion of CO_2 into chemicals and fuels is an alternative to alleviate climate change and ocean acidification.The catalytic reduction of CO_2 by H_2 can lead to the formation of various products:carbon monoxide,carboxylic acids,aldehydes,alcohols and hydrocarbons.In this paper,a comprehensive thermodynamics analysis of CO_2 hydrogenation is conducted using the Gibbs free energy minimization method.The results show that CO_2 reduction to CO needs a high temperature and H_2/CO_2 ratio to achieve a high CO_2 conversion.However,synthesis of methanol from CO_2 needs a relatively high pressure and low temperature to minimize the reverse water-gas shift reaction.Direct CO_2 hydrogenation to formic acid or formaldehyde is thermodynamically limited.On the contrary,production of CH_4 from CO_2 hydrogenation is the thermodynamically easiest reaction with nearly 100%CH4 yield at moderate conditions.In addition,complex reactions with more than one product are also calculated in this work.Among the considered carboxylic acids(HCOOH,CH_3COOH and C_2H_5COOH),propionic acid dominates in the product stream(selectivity above 90%).The same trend can also be found in the hydrogenation of CO_2 to aldehydes and alcohols with the major product of propionaldehyde and butanol,respectively.In the process of CO_2 hydrogenation to alkenes,low temperature,high pressure,and high H_2 partial pressure favor the CO_2 conversion.C_4H_6 is the most thermodynamically favorable among all considered alkynes under different temperatures and pressures.The thermodynamic calculations are validated with experimental results,suggesting that the Gibbs free energy minimization method is effective for thermodynamically understanding the reaction network involved in the CO_2 hydrogenation process,which is helpful for the development of high-performance catalysts.Chunmiao Jia Jiajian Gao Yihu Dai Jia Zhang Yanhui Yang 2016Journal of Energy Chemistry2016,25,6:2
7The effect of slow shot speed and casting pressure on the 3D microstructure of high pressure die casting AE44 magnesium alloy显示文摘3D reconstruction and 2D observation were conducted to characterize the microstructure of the castings produced through high pressure die casting with different parameters.Our results indicate that shrinkage pores generally co-existed with externally solidified crystals(ESCs).In specimen produced without fast slow shot speed,big net-shrinkage pores accompanied with ESCs were found in the center of the specimen.When the casting pressurization was introduced,the shrinkage pores gathered to the specimen center and became much less due to the optimization of melt feeding.Much more porosity was found near the gate rather than in the middle of the rod bar,especially gas pores.Thefilling process simulation reveals that the middle position of the bars wasfirstlyfilled and followed by the near gate position accompanied with one intense turbulentflow.Chaosheng Ma Wenbo YU Tongtong Zhang Zihua Zhang Yihu Ma Shoumei Xiong 2023Journal of Magnesium and Alloys2023,11,2:2
