Photoelectron emission from metal surfaces by ultrashort laser pulses
(American Physical Society, 2006-12)
Electron emission from metal surfaces produced by short laser pulses is studied within the framework of the distorted-wave formulation. The proposed approach, named surface-Volkov (SV)approximation, makes use of the ...
Potential energy surface of H2O on Al{111} and Rh{111} from theoretical methods
(American Institute of Physics, 2012-11)
The potential energy surfaces of molecular water on the Al{111} and on theRh{111} metal surfaces have been investigated using density functional theory. Similarlandscapes were found on both surfaces. In the only minimum ...
The interaction of metal oxide surfaces with complexing agents dissolved in water
(Elsevier Science Sa, 2000-01)
Upon exposure to liquid water or to aqueous solutions, the surfaces of metal oxide particles or films undergo a series of chemical reactions that are dictated to a large extent by the chemistry of the metal ions involved. ...
Dynamics of RS-(Au-SR)x staple motifs on metal surfaces: From nanoclusters to 2D surfaces
(American Chemical Society, 2020-02-06)
Limited stability of metal nanoparticles hinders their long-term uses and applications. For metal nanoclusters, this is even more critical, as physicochemical properties rely on the structure of only a few hundred atoms. ...
Silicon Quantum Dots Metal-Enhanced Photoluminescence by Gold Nanoparticles in Colloidal Ensembles: Effect of Surface Coating
(American Chemical Society, 2018-11)
In the present study, we report the photophysical properties of colloidal ensembles of silicon quantum dots (SiDs) and gold nanoparticles (AuNPs), particularly focusing on investigating metal-enhanced photoluminescence ...
Surface influence on the metalation of porphyrins at the solid-liquid interface
(American Chemical Society, 2017-09)
The insertion of a metal atom in the central cavity of adsorbed porphyrins is an important subject as it allows specific control over the functionality of the molecule. In this work, metalation of protoporphyrin IX (PPIX) ...
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 ...
Two-dimensional chiral assemblies of chiral modifiers at metal surfaces: Alanine succinic acid adsorption on Cu(110)
(Facultad Experimental de Ciencias de la Universidad del Zulia, 2011)
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) ...
