Ab initio study of magnetic effects at material interfaces .
… and surfaces; (b) the impact of these changes on interfacial energies and structures; and (c) the behavior of point defects (including vacancies, impurities and adatoms) at interfaces. We first develop a simple, general energy functional for ferromagnetic materials based upon a local spin density …

The Effect of Adhesion on the Contact of an Elastica with a Rigid Surface
… dependent on the ability to measure surface and interfacial energies. The surface energies of liquids may be measured accurately using a variety of techniques; however, surface energies of solids are much more difficult to accurately measure. In an attempt to develop a method that can be used to …

The Effect of Work of Adhesion on Contact of a Pressurized Blister With a Flat Surface
The ability to accurately measure surface and interfacial energies affects our understanding of friction, wear, bonding and adhesion. Although there are accurate ways to measure the surface energies of liquids, the surface energies of solids have been harder to characterize. In order to broaden the …
