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 ...
Mechanisms of surface-relief gratings formation in layer-by-layer films from azodyes
(2003-09-04)
Surface-relief gratings are photoinscribed on ionically adsorbed layer-by-layer (LBL) films of an azodye, Brilliant Yellow (BY), which was layered alternately with a polyelectrolyte. Photoinscription is performed by impinging ...

Effect of artificial aging on the surface roughness and microhardness of resin-based materials
(2016-03-01)
This study sought to verify the effects of aging on the surface roughness (Ra) and microhardness (Knoop hardness number [KHN]) of resin-based restorative materials protected with a surface sealer. Disc specimens of 2 ...
Effect of extrinsic pigmentation and surface treatments on biaxial flexure strength after cyclic loading of a translucent ZrO2 ceramic
(2019-11-01)
Objective: To evaluate the influence of extrinsic pigmentation on the biaxial flexural strength and surface topographic of translucent Y-TZP (InCoris TZI – Sirona – USA) subjected to several surface treatments. Methods: ...
Spot-beam effect in grazing atom-surface collisions: From quantum to classical
(IOP Publishing, 2018-10)
Grazing incidence fast atom diffraction (GIFAD) is a sensitive tool for surface analysis, which strongly relies on the quantum coherence of the incident beam. In this article we study the spot-beam effect, due to contributions ...
Surface diffusion of graphs: Variational formulation, error analysis, and simulation
(Society for Industrial and Applied Mathematics, 2004-12)
Surface diffusion is a (fourth-order highly nonlinear) geometric driven motion of a surface with normal velocity proportional to the surface Laplacian of mean curvature. We present a novel variational formulation for graphs ...
Quantum interference in grazing scattering of swift He atoms from LiF(001) surfaces: Surface eikonal approximation
(Elsevier Science, 2009-01)
This work deals with the interference effects recently observed in grazing collisions of few-keV atoms with insulator surfaces. The process is studied within a distorted-wave method, the surface eikonal approximation, ...
Effects of different surface treatments of zirconia on the bond strength of self-adhesive resinous cement
(2017-01-02)
Purpose: The aim of this study was to evaluate the effects of different zirconia surface treatments on the bond strength of two self-adhesive resinous cements (SARC). Methods: Two hundred and eight cylindrical specimens ...
