Coupling experimental with simulation studies into the impact factors and reaction mechanism of sawdust char pressured hydrogasification on K-modified transition metal composite catalysts.

The utilization of biomass char was hindered by the low gasification activity due to thick ring structures and unclear gasification mechanism. Herein, the mechanism was elucidated by experimental and DFT to improve the activity. The results demonstrated that temperature increased the gasification activity but did not changed the order of gasification activity of samples.

Topography-specific isotropic tunneling in nanoparticle monolayer with sub-nm scale crevices.

Material used in flexible devices may experience anisotropic strain with identical magnitude, outputting coherent signals that tend to have a serious impact on device reliability. In this work, the surface topography of the nanoparticles (NPs) is proposed to be a parameter to control the performance of strain gauge based on tunneling behavior. In contrast to anisotropic tunneling in a monolayer of spherical NPs, electron tunneling in a monolayer of urchin-like NPs actually exhibits a nearly isotropic response to strain with different loading orientations.

Proteomic analysis of salt-responsive proteins in oat roots (Avena sativa L.).

Background: Oat is considered as a moderately salt-tolerant crop that could be used to improve saline and alkaline soil. Previous studies have focused on short-term salt stress exposure (0.5-48 h), while molecular mechanisms of salt tolerance in oat remain unclear.

Electrical conduction of nanoparticle monolayer for accurate tracking of mechanical stimulus in finger touch sensing.

A flexible strain gauge is an essential component in advanced human-machine interfacing, especially when it comes to many important mobile and biomedical appliances that require the detection of finger touches. In this paper, we report one such strain gauge made from a strip of nanoparticle monolayer onto a flexible substrate. This proposed gauge operates on the observation that there is a linear relationship between electrical conduction and mechanical displacement in a compressive state.
