Purpose: The purpose of this study was twofold: 1) to characterize the zirconia (Y-TZP) surfaces through scanning electronic microscopy associated with energy-dispersive spectroscopy and atomic force microscopy after the ...

The thermodynamic stability of nanocrystalline SnO2–TiO2 solid solutions was studied experimentally. Microcalorimetry of water adsorption revealed a systematic decrease in the surface energy with increasing Ti4+ content ...

The so-called local plasma approximation is generalized to deal with projectiles colliding with surfaces of amorphous solids and with a specific crystalline structure (plannar channeling). Energy loss of protons grazingly ...

An average value for the surface energy (γ-S) of palygorskite was determined from experimental data of spreading pressure, the surface tension of water and its contact angle using a formula based on the combination of the ...

The potential energy surfaces of molecular water on the Al{111} and on theRh{111} metal surfaces have been investigated using density functional theory. Similarlandscapes were found on both surfaces. In the only minimum ...

In this work it was investigated the effect of the exposure to different plasmas on the wettability of silicone samples. We have observed that oxygen. argon, and hydrogen glow discharges are quite effective in reducing the ...
