Shear-Induced Surface-to-Bulk Transport at Room Temperature in a Sliding Metal–Metal Interface
Predictions from molecular dynamics (MD) simulations, that sliding at a metal–metal interface causes vortices in the near-surface region that transport atoms from the surface into the subsurfaceExpand
Pressure Dependence of Shear Strengths of Thin Films on Metal Surfaces Measured in Ultrahigh Vacuum
The friction coefficient is measured for systems consisting of a thin potassium chloride film deposited onto a variety of clean, flat metal substrates, namely Pb, Sn, Au, Ag, Cu, Pd, Fe, Ta, and twoExpand
Tribological Properties of Films Formed by the Reaction of Carbon Tetrachloride with Iron
The tribological properties of halide films grown on iron by reaction with carbon tetrachloride vapor at a temperature of 617 K and a pressure of 1.7 Torr are compared, in ultrahigh vacuum, withExpand
Porous MoxCy/SiO2 Material for CO2 Hydrogenation
The synthesis and characterization of an inexpensive porous MoxCy/SiO2 material is presented, which was obtained by mixing ammonium hexamolybdate, sucrose, and a mesoporous silica (SBA-15), with aExpand
Shear properties of potassium chloride films on iron obtained using density functional theory.
Density functional theory is used to calculate the shear strength of a thin KCl film grown epitaxially on an Fe(100) substrate and the values are in excellent agreement with the experimentally measured value of 65 ± 5 MPa. Expand
Adsorption of hydrogen on the surface and sub-surface of Cu(111).
DFT calculations show that the most stable position for hydrogen adsorption on Cu(111) is on hollow surface sites, but that hydrogen can be trapped in the second sub-surface layer. Expand
Surface segregation of gold for Au/Pd(1 1 1) alloys measured by low-energy electron diffraction and low-energy ion scattering
Abstract The surface composition of a Au/Pd(1 1 1) alloy formed by depositing five monolayers of gold onto clean Pd(1 1 1) at 300 K in ultrahigh vacuum and heating to various temperatures is measuredExpand
A silica/carbon composite as anode for lithium-ion batteries with a large rate capability: Experiment and theoretical considerations
Abstract New generations of materials are necessary to provide practical and economical solutions for electrode fabrication in lithium ion batteries. To this end, in the present work we propose aExpand
Low-temperature, shear-induced tribofilm formation from dimethyl disulfide on copper.
The novel, low-temperature tribofilm formation observed here is ascribed to a shear-induced intermixing of the surface layer(s) with the subsurface region as suggested using previous molecular dynamics simulations. Expand
