OBJECTIVE The purpose of this study was to investigate the morphological and atomic changes on the root surface by stereoscopy, field emission-scanning electron microscopy (FE-SEM), and energy dispersive X-ray spectroscopy (SEM-EDX) after erbium, chromium:yttrium, scandium, gallium, garnet (Er,Cr:YSGG) laser irradiation in vitro. SUMMARY BACKGROUND DATA There have been few reports on morpholo...
Intermetallide phase formation was studied in a powdered Fe–Al system under layer by layer laser cladding with the aim of fabricating the gradient of properties by means of changing the Fe–Al concentration ratio in the powder mixture from layer to layer. The relationships between the laser cladding parameters and the intermetallic phase structures in the consecutively cladded layers were determ...
A novel, high throughput method to characterize the chemistry of ultra-thin diamond-like carbon films is discussed. The uses surface sensitive SEM/EDX provide substrate-specific, semi-quantitative silicon nitride/DLC stack composition protective extensively used in hard disk drives industry and at Angstrom-level. output correlated TEM direct, gauge-capable film thickness information using multi...
H2S reduction over Pure and Sulphur doped TiO2 nanoparticles was studied in this work. The parameter was catalytic destruction of H2S gas under high temperature of 450C using fixed bed catalytic system under laboratory conditions. Under these conditions 99.97% reduction was achieved using S-doped TiO2. 2.89% Sulphur was adsorbed on S-doped TiO2 nanoparticles to form Ti(SO4)2. Comparatively, no ...
