Transfer matrix approach to metal surfaces vibrations
(Elsevier B.V., 1989)
Surface phonons propagating in arbitrary directions in the surface of FCC metals are studied via vibrational Green's functions obtained through the definition of transfer matrices. The dynamical matrix is described in the ...
Surface Porphyrins Metalate with Zn Ions from Solution
(American Chemical Society, 2015-12)
Controlling the metalation of surface porphyrins is a critical process in porphyrin-based devices. Indeed, surface porphyrins are known to metalate in ultrahigh vacuum from codeposited metal atoms or substrate atoms; ...
Surface modification by metal ion implantation forming metallic nanoparticles in insulating matrix.
(Kusadasi, 2013-09-15)
There is special interest in the incorporation of metallic nanoparticles in a surrounding dielectric matrix for obtaining composites with desirable characteristics such as for surface plasmon resonance, which can be used ...
Subsurface bonding of hydrogen in transition metals: dependence on surface orientation
(1994)
The calculation of the surface-induced enhancement of the binding energy of hydrogen impurities in transition metals, previously reported for close-packed surfaces, are extended to open surfaces in the fcc and bcc structures. ...
Quantitative Determination of the Number of Surface Active Sites and the Turnover Frequencies for Methanol Oxidation over Metal Oxide Catalysts: Application to Bulk Metal Molybdates and Pure Metal Oxide Catalysts
(Academic Press Inc Elsevier Science, 2001-09-23)
The present work investigates the number and nature of the surface active sites and the catalytic activity of bulk metal molybdates and bulk metal oxides on methanol selective oxidation. Bulk metal molybdates were synthesized ...
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 ...
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 ...
Time-dependent induced potentials in convoy electron emission
(Elsevier Science, 2006-12)
We study the time-dependent induced potentials at the convoy electron position due to the self-interaction with a metal surface and to the shock wave created by the positive hole (vacancy) left. The time evolution of these ...
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 ...
