Chemical sensors based on semiconducting metal oxide nanocrystals are of academic and practical significance in industrial processing and environment-related applications. Novel alcohol response sensors using two-dimensional WO(3) nanoplates as active elements have been investigated in this paper. Single-crystalline WO(3) nanoplates were synthesized through a topochemical approach on the basis ...

This reaffirmation of teachers has been a leading factor in the development of recent strategies for school improvement The reports by the Carnegie Task Force and the Holmes Group are two prominent examples of proposals aimed specifically at problems within the teaching profession. These reports are significant in that they have helped place teaching squarely at the center of current educationa...

We revisit the far from equilibrium escape problem across a fluctuating potential barrier that is driven by asymmetric, unbiased dichotomous noise. Our closed analytical solution for arbitrary noise strengths reveals new aspects of the so-called ‘‘resonant-activation’’ effect and leads to interesting implications regarding far from equilibrium or externally controlled chemical reaction processe...

A two dimensionally assembled monolayer of hexagonal convexo-convex β-cobalt hydroxide nanoplates as a self-disposable sacrificial epi-template leads to a highly vertical alignment of zinc oxide nanorods array having a good electrical contact with metal or semiconductor layer on a substrate in a hydrothermal process.

An excellent, platinum free fiber counter electrode (CE) was successfully fabricated, consisting of porous, single crystalline titanium nitride (TiN) nanoplates grown on carbon fibers (CF). The fiber-shaped dye-sensitized solar cells (FDSSCs) based on the TiN-CF CE show a high conversion efficiency of 7.20%, comparable or even superior to that of the Pt wire (6.23%).

Fine shape-control of gold nanoparticles was achieved in the presence of an amphiphilic polythiophene with an isothiouronium pendant, by varying the experimental conditions for the crystallization; we succeeded to prepare π-conjugated polythiophene-capped Au nanoplates, Au nanocubes and Au nanoparticles with an average spherical diameter of (7.7 ± 1.6) nm.

In this study, we examined whether catalysts with many defects have excellent photoactivity. We prepared ZnO nanoplates varying degrees of in a short time 4 h by the crystal growth temperature at 50, 100, 150, and 200 °C under strong alkali NaOH atmosphere 4.0 M. During high-temperature preparation ZnO, were reduced crystallinity was further increased. crystallized systems over 100 °C, rhombic ...
