Compositional modulation and surface stability in InGaP films: Understanding and controlling surface properties
(2007-04-08)
We investigate the formation of compositional modulation and atomic ordering in InGaP films. Such bulk properties - as well as surface morphologies - present a strong dependence on growth parameters, mainly the V/III ratio. ...
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 ...
Minimal Lagrangian surfaces in the tangent bundle of a Riemannian surface
(ELSEVIER SCIENCE BV, 2011)
Given an oriented Riemannian surface (Sigma, g), its tangent bundle T Sigma enjoys a natural pseudo-Kahler structure, that is the combination of a complex structure 2, a pseudo-metric G with neutral signature and a symplectic ...
Liquid/surface interaction during pool boiling of DI-water on nanocoated heating surfaces
(2018-11-01)
This study focuses on the effect of the nanostructured heating surface on the heat transfer coefficient (HTC) considering the nanofluid concentration used for coating surfaces and the heating surface morphology. Copper ...
Differential geometry of intersection curves in R(4) of three implicit surfaces
(Elsevier B.V., 2009-05-01)
We present algorithms for computing the differential geometry properties of intersection Curves of three implicit surfaces in R(4), using the implicit function theorem and generalizing the method of X. Ye and T. Maekawa ...
Structural and electronic properties of PbTiO3 slabs: a DFT periodic study
(Elsevier B.V., 2004-03-10)
Structural and electronic properties of the bulk and relaxed surfaces (TiO2 and PbO terminated) of cubic PbTiO3 are investigated by means of periodic quantum-mechanical calculations based on density functional theory. It ...

Immobilisation of apatite on Ti30Ta alloy surface by electrospinning of PCL
(Ice Publishing, 2017-06-01)
Surface modifications of titanium alloy have been extensively researched for the purpose of increasing the biocompatibility of medical implants. In this study, a Ti30Ta alloy surface was modified by functionalisation with ...
Chemical and electrochemical oxidation of silicon surfaces functionalized with APTES: the role of surface roughness in the AuNPs anchoring kinetics
(American Chemical Society, 2013-05)
Oxidation of Si(111) surfaces is a procedure widely used for their further functionalization with 3-aminopropyltriethoxysilane (APTES). In the present work, the formation of silicon oxide is carried out by chemical and ...
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 ...
