Laser-induced phase explosion: new physical problems when a condensed phase approaches the thermodynamic critical temperature
Abstract. Three kinds of thermal processes may lead to material loss from a laser-irradiated surface: 1) vaporization, 2) normal boiling, and 3) explosive boiling. The latter is equivalent to phaseExpand
Critical assessment of thermal models for laser sputtering at high fluences
A critical assessment of thermal models for laser sputtering at high fluences is presented. It is argued that the model explaining such sputtering by involving a subsurface superheating effectExpand
New insights on the mechanism of palladium-catalyzed hydrolysis of sodium borohydride from 11B NMR measurements.
TLDR
The results indicate that in the palladium-catalyzed process the rate constants of the exchange processes are higher than those of the corresponding hydrolysis reactions. Expand
Hydrogen generation by hydrolysis of alkaline NaBH4 solution with Cr-promoted Co–B amorphous catalyst
Abstract Cr-modified Co–B (Co–Cr–B) catalyst alloy powders have been synthesized by chemical reduction of cobalt and chromium salt at room temperature to study the hydrogen production by catalyticExpand
Improved visible light photocatalytic activity of TiO2 co-doped with Vanadium and Nitrogen
Abstract V- and N-codoped TiO 2 photo-catalyst is synthesized by sol–gel method to sensitize TiO 2 to visible light. The concentrations of V and N were varied and optimized to enhance photo-catalyticExpand
Systematic investigation on the interaction of bovine serum albumin with ZnO nanoparticles using fluorescence spectroscopy.
TLDR
The synchronous fluorescence spectra reveal that the microenvironment close to both the tyrosine and tryptophan residues of BSA is perturbed and that the hydrophobicity of both the residues is increased in the presence of ZnO NPs. Expand
Efficient catalytic properties of Co–Ni–P–B catalyst powders for hydrogen generation by hydrolysis of alkaline solution of NaBH4
Abstract The aim of the present work is to study the catalytic efficiency of amorphous Co–Ni–P–B catalyst powders in hydrogen generation by hydrolysis of alkaline sodium borohydride (NaBH 4 ). TheseExpand
Comments on explosive mechanisms of laser sputtering
Laser sputtering differs from ion sputtering mainly in the important role played by thermal effects. These include not only vaporization from the extreme outer surface and boiling from an extendedExpand
Pulsed laser deposition of diamond-like carbon films: reducing internal stress by thermal annealing
Abstract In order to obtain diamond-like carbon (DLC) films of relevant thickness (exceeding 1 μm), it is necessary to solve the critical problem related to the internal compressive stress (some GPa)Expand
