Surface composition of PdCuAu ternary alloys: A combined LEIS and XPS study
(John Wiley & Sons Ltd, 2015-07)
PdCuAu ternary alloy samples with different composition were synthesized on top of ZrO2-modified porous stainless steel disks by the sequential electroless deposition technique. The structure, morphology and bulk composition ...
Estudio por XPS y TGA de nanocatalizadores de hierro soportados sobre silicio bajo tratamientos térmicos, en oxígeno e hidrógeno
(Universidad de Los Andes, 2009)
Identification of surface processes in individual minerals of a complex ore through the analysis of polished sections using polarization microscopy and x-ray photoelectron spectroscopy (Xps)
(MDPI, 2018-09-28)
Understanding the changes of a mineral during ore processing is of capital importance for the development of strategies aimed at increasing the efficiency of metal extraction. This task is often difficult due to the ...
Surface chemical reactions induced on pyrite by ion bombardment
(Elsevier Science, 2018-01)
Through X-ray photoemission spectroscopy (XPS), we studied the chemical changes induced in a natural crystal of pyrite (FeS2) upon exposure to 4.5 keV He+ beam. We found an important reducing effect induced by ion bombardment ...
Theoretical studies of energy photoemission spectra (xps) of s an so2 adsorbed on ni clusters by hartree-fock method
(Revista Mexicana de Física, 2009)
XPS study of the surface properties and Ni particle size determination of Ni supported catalysts
(Wiley, 2014-04)
The surface properties of Ni/MgAl2O4 catalysts doped with Ce or Pr were analyzed by XPS after treatment in an inert and reductive atmosphere at 400 °C. The Ce-promoted solids presented the Ce3+/Ce4+ couple on the surface ...
XPS study of the state of iridium, platinum, titanium and oxygen in thermally formed IrO2+TiO2+PtOx films
(Elsevier Science BvAmsterdamHolanda, 2000)
Improvement of the corrosion resistance of polysiloxane hybrid coatings by cerium doping
(Elsevier B.V., 2010-10-01)
Polysiloxane hybrid films were deposited on stainless steel by dip-coating using a sol prepared by hydrolytic co-polycondensation of tetraethoxysilane (TEOS) and 3-methacryloxy propyltrimethoxysilane (MPTS), followed by ...
