Oral exfoliative cytology and corrosion of metal piercings: Tissue implications
(Springer Heidelberg, 2019-04)
Objectives: A group of adolescents with oral piercings was studied to determine the presence of metallic particles in cells exfoliated from the mucosa surrounding their metal oral piercings and the association between such ...
Investigation of the Nature and Number of Surface Active Sites of Supported and Bulk Metal Oxide Catalysts Through Methanol Chemisorption
(CRC Press - Taylor & Francis Group, 2005)
The present Chapter presents a chronological summary of the application (advantages and disadvantages) of probe molecules both in the liquid and gas media to investigate the surface of oxide based materials and heteropoly ...
Nanostructuring of metal surfaces by laser ablation
(InTech, 2016)
Irradiation of materials such as iron and silicon with single nanosecond laser pulses produces nanostructures on its surfaces. Nevertheless, the deposition before irradiation of thin films on the silicon?s surfaces can ...
The adsorption of hydrogen on face centered tetragonal FePd surfaces
(Pergamon-Elsevier Science Ltd, 2004-07)
Adsorption of hydrogen on the ordered FePd face centered tetragonal alloy is investigated using a tight binding theoretical method. The changes in the electronic structure and bonding in the (100), (110) and (111) surfaces ...
Interaction of ultra-short laser pulses with metal surfaces: Impulsive jelliun-Volkov approximation versus the solution of the time-dependent Schrödinger equation
(American Physical Society, 2007-12)
Electron emission coming from the valence band of metal surfaces due to grazing incidence of high frequency ultrashort laser pulses is studied. We introduce a distorted-wave method, named impulsive jellium-Volkov (IJV) ...
Thermal treatment and deposition of alumina in metallic microchannels
(Maney Publishing, 2019-11)
The objective of this work is the generation of a suitable surface, in microchannels of AISI 304 stainless steel for the manufacture of a microreactor, which ensures the anchoring of the active phase. The novelty of the ...
DFT study of the effect in surface energy of metallic overlayers in semiconductorsEstudio DFT del efecto en la energía superficial de sobrecapas metálicas en semiconductores

Surface shape resonances and surface plasmon polariton excitations in bottle-shaped metallic gratings
(American Physical Society, 2001-12)
We study surface plasmon polariton excitations and surface shape resonances in a lossy metallic grating with bivalued cavities. The modal formalism is used to solve the diffraction problem for the infinite grating and the ...
