Abstract Optical and optoelectronic techniques for micro‐ nano‐object manipulation are becoming essential tools in nano‐ biotechnology. Among platforms, photovoltaic tweezers (PVOTs) an emergent technique that particularly successful at producing permanent nanoparticle microstructures. New strategies to enhance the capabilities of PVOT, based on real‐time operation, investigated. This platform uses z ‐cut LiNbO 3 :Fe substrates under excitation by a Gaussian light beam. Unexpected results...
The generation and manipulation of small aqueous droplets is an important issue for nano- biotechnology, particularly, when using microfluidic devices. production very has been frequently carried out by applying intense local electric fields to the fluid, which requires power supplies metallic electrodes. This procedure complicates device reduces its versatility. In this work, we present a novel flexible, best our knowledge, electrodeless optoelectronic method tiny biologically friendly...
Vanadium tetrasulfide (VS4, called patronite as a mineral) is one-dimensional compound with promising properties for energy conversion applications. However, it has been scarcely investigated because of its complex synthesis. In this work, we report detailed investigation about the formation mechanism VS4 (V4+(S22–)2) well structural, transport, and photoelectrochemical properties. To aim, films were grown by solid–gas reaction process between vanadium sulfur at temperatures 350 450 °C...
The tribochemical decomposition of iron pyrite at room temperature involves rich solid-state reactions FeS 2 with impurities such as hydrogen, oxygen and carbon is controlled by the concentrations precursors.
An application of mechanical energy was explored as a new non-thermal method to drive H2 emission from undoped sodium alanate at room temperature. It found that mild rubbing NaAlH4 pellets under vacuum led intensive and almost instantaneous gas emission. The dominating species in the emitted gases (>99%). Traces mono- polyalanes, vapours, CO2 other non-identified were registered. involved several first-order processes, whose characteristic time constants ranged widely 0.6 465 s. None...
The sulfuration of metallic iron layers into pyrite (FeS2) is preceded by an initial stage characterized the transformation monosulfide, which acts as a precursor disulfide. This work presents comprehensive reaction and kinetic model thin films monosulfides when molecular sulfur (S2) atmosphere used. By slowing down reaction, we have been able to follow in situ evolution transport properties (electrical resistivity Seebeck coefficient) Fe during their monosulfides. We show that two different...
The Cover Feature illustrates unconventional approaches (electromagnetic radiation, mechanical bias, electrochemistry way, electrical and magnetic fields…) that could be used as energy sources to surmount the thermodynamic kinetic landscapes on H2-sorption reactions hydrides represented by valleys mountains in picture.
