A numerical study of the simultaneous natural convective heat transfer from the top and bottom surfaces of a thin inclined plate having a wavy surface with constant height
(2019-01-01)
The purpose of the present work is to undertake a numerical study of natural convective heat transfer from a thin, two-sided, two-dimensional inclined plate having a uniform surface temperature. The surface shape is wavy, ...
Surface speciation of phosphate on goethite as seen by InfraRed Surface Titrations (IRST)
(Pergamon-Elsevier Science Ltd, 2018-06-15)
Phosphate adsorption at the metal oxide-water interface has been intensely studied, and the system phosphate-goethite in aqueous media is normally used as a model system with abundant information regarding adsorption-desorption ...
Synthesis in situ of gold nanoparticles by a dialkynyl Fischer carbene complex anchored to glass surfaces
(Elsevier Science, 2016-10-15)
In this work we present a detailed study of classic reactions such as "click reaction" and nucleophilic substitution reaction but on glass solid surface (slides). We used different reactive center of a dialkynylalcoxy ...
The interaction of metal oxide surfaces with complexing agents dissolved in water
(Elsevier Science Sa, 2000-01)
Upon exposure to liquid water or to aqueous solutions, the surfaces of metal oxide particles or films undergo a series of chemical reactions that are dictated to a large extent by the chemistry of the metal ions involved. ...
Protein Adsorption at Solid Surfaces and Protein Complexation with Humic Acids
(Sociedad Chilena de la Ciencia del Suelo, 2008)
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 ...
New aspects of the surface chemistry of sulfur on Au(111): Surface structures formed by gold-sulfur complexes
(Elsevier Science, 2019-09)
Sulfur adsorption on gold surfaces has been extensively studied because of the key role of sulfur species in heterogeneous catalysis, and, more recently, due to the interest in the synthesis of anisotropic gold nanoparticles ...
