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. ...

Microbial adhesion and biofilm formation on bioactive surfaces of Ti-35Nb-7Zr-5Ta alloy created by anodization
(2021-10-01)
This study evaluated the microbial colonization (adhesion and biofilm) on modified surfaces of a titanium alloy, Ti-35Nb-7Zr-5Ta, anodized with Ca and P or F ions, with and without silver deposition. The chemical composition, ...
Formation of SO4H2 on the Pt{110}(1×2) surface. A DFT study
(Elsevier Science, 2021-05)
Density functional theory is used to calculate energy differences for two surface reactions on the Pt{110}(1×2) surface: SO2 ↔ SO + O and SO3 ↔ SO2 + O, first. Formation of SO3 is preferred energetically. Second, several ...
Micro-scale surface-patterning influences biofilm formation

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 ...
Streptococcus mutans attachment on a cast titanium surface
(2009-08-13)
This study examined by means of scanning electron microscopy (SEM), the attachment of Streptococcus mutans and the corrosion of cast commercially pure titanium, used in dental dentures. The sample discs were cast in ...
