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 decade. Being composed entirely of
ions and p... 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
background oxygen. For a long time, oxygen interaction with SnO2 has been
treated w... 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 construction and operational principles,
but also in their ... 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 transport at the macro‐ and
nanosc... 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 nanoparticles show
significantly highe... 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
structure, and are thus crucial ... 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 technical developments, which
include innovative i... hiện toàn bộ
