AbstractSome twenty‐five years after they first came to prominence as alternative electrochemical solvents, room temperature ionic liquids (RTILs) are currently being employed across an increasingly wide range of chemical fields. This review examines the current state of ionic liquid‐based electrochemistry, with particular focus on the work of the last...... hiện toàn bộ
AbstractTin dioxide is the most commonly used material in commercial gas sensors based on semiconducting metal oxides. Despite intensive efforts, the mechanism responsible for gas‐sensing effects on SnO2 is not fully understood. The key step is the understanding of the electronic response of SnO2 in the presence of backgrou...... hiện toàn bộ
AbstractDye‐sensitized solar cells (DSSCs) based on organic dyes adsorbed on oxide semiconductor electrodes, such as TiO2, ZnO, or NiO, which have emerged as a new generation of sustainable photovoltaic devices, have attracted much attention from chemists, physicists, and engineers because of enormous scientific interest in not only their const...... hiện toàn bộ

AbstractDiffusive transport of particles or, more generally, small objects, is a ubiquitous feature of physical and chemical reaction systems. In configurations containing confining walls or constrictions, transport is controlled both by the fluctuation statistics of the jittering objects and the phase space available to their dynamics. Consequently, the study of t...... hiện toàn bộ

AbstractThe origin of the peroxidase‐like activity of gold nanoparticles and the impact of surface modification are studied. Furthermore, some influencing factors, such as fabrication process, redox property of the modifier, and charge property of the substrate, are investigated. Compared to amino‐modified or citrate‐capped gold nanoparticles, unmodified gold nanop...... hiện toàn bộ
AbstractA selection of recent theoretical and experimental studies on electrolytic hydrogen evolution is presented. It is demonstrated with well‐defined model surfaces that this reaction is a very structure‐sensitive process. Crystallographic orientation, defect density and surface composition are parameters that determine the local geometric and electronic surface...... hiện toàn bộ
AbstractAdhesion can be quantified by measuring the distance between the interacting surfaces. Reflection interference contrast microscopy (RICM), with its ability to measure inter‐surface distances under water with nanometric precision and milliseconds time resolution, is ideally suited to studying the dynamics of adhesion in soft systems. Recent tech...... hiện toàn bộ
