Aging of plasma-activated copper and gold surfaces and its hydrophilic recovery after water immersion
(Elsevier B.V., 2014-01-01)
A significant increase of surface hydrophilicity of copper and gold surfaces was obtained after atmospheric pressure plasma treatment using the surface dielectric barrier discharge with specific electrode geometry, the ...
Effect of microfin surfaces on boiling heat transfer using HFE-7100 as working fluid
(2020-07-01)
One promising way to enhance the heat transfer coefficient (HTC) and the critical heat flux (CHF) is modifying the heating surface morphology by using machining techniques, coating, and chemical processes. Microstructured ...
Periodic study on the structural and electronic properties of bulk, oxidized and reduced SnO2(110) surfaces and the interaction with O-2
(Elsevier B.V., 2002-06-10)
The structural and electronic properties of bulk and both oxidized and reduced SnO2(110) surfaces as well as the adsorption process of O-2 on the reduced surface have been investigated by periodic DFT calculations at B3LYP ...

Aging effect of atmospheric air on zirconia surfaces treated by nonthermal plasma
(2015-01-01)
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 ...
Surface effects on moving vortices in superconducting stripes
(Elsevier B.V., 2007-04-15)
Size and surface dynamical effects are investigated in thin superconducting stripes with variable width. We perform numerical simulations of the vortex dynamics, with the inclusion of the surface confining potential and a ...

Association of cationic surfactants to humic acid: Effect on the surface activity
(Elsevier, 2006)
Surface properties of aqueous solutions of mixtures of humic acid, HA, and a series of cationic surfactants, CnTAB, have been studied. For a fixed amount of HA, the concentration of surfactant at which micelle-like aggregates ...
