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 ...
The Nanocrystalline SnO2–TiO2 System‒Part II: Surface Energies and Thermodynamic Stability
(Easton, 2016)
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 ...
Model calculation for energy loss in ion-surface collisions.
(American Physical Society, 2003-12)
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 ...
Investigations on the stability of plasma modified silicone surfaces
(Kluwer Academic/plenum Publ, 2004-03-01)
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 ...
Effect of amino-terminated substrates onto surface properties of cellulose esters and their interaction with lectins
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Films of cellulose acetate butyrate (CAB) and carboxymethylcellulose acetate butyrate (CMCAB) were deposited from ethyl acetate solutions onto bare silicon wafers (Si/SiO2) or amino-terminated surfaces (APS) by means of ...
Effect of collagen matrix saturation on the surface free energy of dentin using different agents
(2015)
The surface free energy of conditioned-dentin is one of the factors that interfere with monomeric infiltration of the interfibrillar spaces. Saturation of the tooth matrix with different substances may modulate this energy ...
Effect of Collagen Matrix Saturation on the Surface Free Energy of Dentin using Different Agents
(2015-07-01)
INTRODUCTION: The surface free energy of conditioned-dentin is one of the factors that interfere with monomeric infiltration of the interfibrillar spaces. Saturation of the tooth matrix with different substances may modulate ...
DFT study of the formation of Cd-Ag surface alloys on Ag surfaces
(Elsevier Science, 2016-06)
We investigate the feasibility of forming a surface alloy between Ag and Cd on Ag surfaces, employing Density Functional Theory calculations. Six layers slabs are used to model surface alloy systems. Adsorption energies ...
Wettability and surface free energy on heat-treated Pinus sp. and Erisma sp. Woods
(2017-03-01)
This study aims to investigate wettability, surface polarity, and mass loss in two reforestation woods, Pinus sp. (softwood) and Erisma sp (hardwood), after heat treatment. The wood samples were heated to 100 °C, 140 °C ...
Dynamics of the interaction between body fluid and Ti cp: the influence of surface functionalization in the first stages of osseointegration
(SBEB - Sociedade Brasileira de Engenharia Biomédica, 2014-03-01)
INTRODUCTION: Regenerative therapies using biomaterials require accurate information on interactions between the implanted material and the human body. To improve the process of bone regeneration it is necessary to obtain ...
