The anodic dissolution of metals is an important topic for battery design,material finishing and metal *** liquids are being used in all of these areas but the research on the anodic dissolution is relatively few in these *** study investigates the behaviour of 9 metals in an ionic liquid [C;mim][Cl] and a deep eutectic solvent,Ethaline,which is a 1:2 mol ratio mixture of choline chloride and ethylene *** is shown that for the majority of metals studied a quasi-passivation of the metal surface occurs,primarily due to the formation of insoluble films on the electrode *** behaviour of most metals is different in [C;mim][Cl] to that in Ethaline due in part to the differences in *** formation of passivating salt films can be decreased with stirring or by increasing the electrolyte temperature,thereby increasing ligand transport to the electrode surface.

We propose distributed static and dynamic event-triggered control laws to solve the consensus problem for multiagent systems with output *** the condition that the underlying graph is undirected and connected,we show that consensus is achieved under both event-triggered control laws if and only if the average of the initial states is within the saturation *** simulations are provided to illustrate the effectiveness of the theoretical results and to show that the control laws lead to reduced need for inter-agent communications.

制备了以Li2SO4为基体、A l2O3为填充物的复合质子传导膜.采用电化学阻抗波谱分析法(EIS)研究了掺杂不同组分(Li2WO4或Na2SO4)以及掺杂不同比例时制备的不同厚度的复合质子传导膜的离子(电)传导率.分析结果表明,在Li2SO4中掺杂一定比例的Li2WO4或Na2SO4均可提高膜的离子传导率,Li2WO4对复合膜性能的影响优于Na2SO4.扫描电镜(SEM)分析显示,掺杂Li2WO4的复合膜结构更加致密和紧凑.实验结果表明,由Li2SO4、Li2WO4和A l2O3制备的复合膜的适宜组成为75%Li2SO4/Li2WO4混合物(Li2SO4与Li2WO4摩尔比为9∶1)+25%A l2O3,其离子传导率在600,650,700和750℃时分别高达0.16,0.38,0.46和0.52S/cm,适宜的膜厚为0.8mm.文中还研究了以H2S为燃料、复合Mo-N i-S为阳极、复合Li2SO4为质子传导膜、复合N iO为阴极、空气为氧化剂的单电池的电化学性能,发现Li2SO4+Li2WO4+A l2O3复合膜的电化学性能较优.
