(Superficies y Vacio, 2013-01-16)
Characterization of metal-biomass interactions in the lanthanum(III) biosorption on Sargassum sp using SEM/EDX, FTIR, and XPS: Preliminary studies
(Elsevier B.V., 2014-03-01)
This work investigates the mechanisms involved in the biosorption of lanthanum (La(III)) on Sargassum sp. biomass using scanning electron microscopy (SEM), SEM coupled to energy dispersive X-ray spectroscopy (SEM/EDX), ...
Pr3+ surface fraction in CePr mixed oxides determined by XPS analysis
(Elsevier Science, 2018-01)
CePr mixed oxides were previously studied as supports for Water Gas Shift catalysts, considering their promising textural and redox properties arising from the presence of a non-stoichiometric oxide. A very small Ce3+ ...
XPS Analysis of Enzyme and Mediator at the Surface of a Layer-by-Layer Self-Assembled Wired Enzyme Electrode
(American Chemical Society, 2014-11)
High potential purified Trametes trogii laccase has been deposited in mono- and multilayer thin films on gold surfaces by layer-by-layer electrostatic adsorption self-assembly. The osmium bipyridil redox relay sites on ...
SEM/EDX and XPS studies of niobium after electropolishing
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The studies of niobium after electrochemical polishing EP in sulfuric-methanesulfonic acid mixture were performed. The NbOx/Nb surface was studied by SEM/EDX and XPS methods to find out the chemical composition of the ...
XPS characterization of sensitized n-TiO2 thin films for dye-sensitized solar cell applications
(ELSEVIER SCIENCE BV, 2008)
TiO2 thin films, employed in dye-sensitized solar cells, were prepared by the sol-gel method or directly by Degussa P25 oxide and their surfaces were characterized by X-ray photoelectron spectroscopy (XPS) and scanning ...
Transcription analysis of pilS and xpsEL genes from Xylella fastidiosa
Estudo do biomaterial Ti-6Al-4V empregando-se técnicas eletroquímicas e XPS
(Sociedade Brasileira de Química, 2002-02-01)
The Ti-6Al-4V alloy used as biomaterial has been used over the last years. The literature shows controversies concerning the kind and the chemical composition of the film naturally and elctrochemically formed on the surface ...
