Exploring the nature of wetting by water of surfaces of alkane-amidethiols adsorbed on gold using the electrostatic potential topology

Article Abstract:

The nature of the interaction of water molecules with the surface of a set of experimentally well-studied alkane-amidethiols adsorbed on a gold(111) surface and its effect on the water contact angle is studied. The findings indicate that the water contact angle decreases systematically as the number of minima by surface cell unit and the electrostatic potential magnitude at these minima increases.

High-temperature diffusion lithium adsorbed on Ru(001)

Article Abstract:

A new method to measure, at high temperature, the macroscopic diffusion coefficient for lithium adsorbed on a Ru(001) single-crystal surface, using a nuclear magnetic resonance (NMR) experiments is presented. The study concluded that NMR techniques are able to open a new window in the studies of macroscopic diffusion on surfaces.

Nature of the Lewis acid sites on Molybdenum and ruthenium sulfides: An electrostatic potential study

Article Abstract:

An electrostatic potential-based methodology is presented to study the nature of Lewis acid sites on molybdenum and ruthenium sulfides. The results obtained suggest that the presence of Lewis acid sites on the MoS2 particles can be the more energetically favorable sites on the S edges with 50% sulfur coverage.
