Identification of fungi isolated from banana rachis and characterization of their surface activity
(Lett Appl Microbiol . 2017 Mar;64(3):246-251, 2017-01-06)
Filamentous fungi are an unexplored source for the production of biosurfactants, but over a decade one of the most surface active molecules called hydrophobins was discovered. There are few techniques to determine the ...
Association of cationic surfactants to humic acid: Effect on the surface activity
(Elsevier, 2006)
Surface properties of aqueous solutions of mixtures of humic acid, HA, and a series of cationic surfactants, CnTAB, have been studied. For a fixed amount of HA, the concentration of surfactant at which micelle-like aggregates ...
Surface coverage dictates the surface bio-activity of d-amino acid oxidase
(Elsevier Science, 2014-03)
This work presents a systematic study on the relationship between the adsorption mechanism and the surface bio-activity of d-amino acid oxidase (pkDAAO). This rational approach is based on measuring the characteristic ...
Surface chemistry can unlock drivers of surface stability of SARS-CoV-2 in variety of environmental conditions
The surface stability and resulting transmission of the SARS-CoV-2, specifically in indoor
environments, have been identified as a potential pandemic challenge requiring investigation. This
novel virus can be found on ...
Aging of plasma-activated copper and gold surfaces and its hydrophilic recovery after water immersion
(Elsevier B.V., 2014-01-01)
A significant increase of surface hydrophilicity of copper and gold surfaces was obtained after atmospheric pressure plasma treatment using the surface dielectric barrier discharge with specific electrode geometry, the ...
Quantification of active sites for the determination of methanol oxidation turn-over frequencies using methanol chemisorption and in situ infrared techniques. 1: Supported metal oxide catalysts
(American Chemical Society, 2001-10)
Methanol oxidation over metal oxide catalysts is industrially important for the production of formaldehyde, but knowledge about the intrinsic catalysis taking place is often obscured by a lack of knowledge as to the number ...
Theoretical study of the diffusion of alkali metals on a Cu(111) surface
(Elsevier, 1997)
We present a theoretical study of the diffusion of Li, Na and K on a Cu(111) surface. Various diffusional paths are identified and characterized in terms of kinetic parameters such as diffusion constants and activation ...
Implementation of diverse non-centrosymmetric layer concepts for tuning the interface activity of a magnesium alloy
(2016-01-01)
Magnesium and its alloys are the lightest metallic materials used for structural applications. Tuning the surface functionalization of magnesium alloys may contribute to increasing their durability. Dry or wet processes ...
Quantitative determination of the number of active surface sites and the turnover frequencies for methanol oxidation over metal oxide catalysts: I. Fundamentals of the methanol chemisorption technique and application to monolayer supported molybdenum oxide catalysts
(Elsevier Science, 2000-11)
A detailed study of the methanol chemisorption and oxidation processes on oxide surfaces allowed the development of a method to quantify the number of surface active sites (Ns) of metal oxide catalysts. In situ infrared ...
