Abstract Intense short laser pulses are an intriguing tool for tailoring surface properties via ultra-fast melting of the surface layer of an irradiated target. Despite extensive studies on the interaction of femto-second laser interaction with matte

Plane-wave density functional theory was used to study the properties of oxygen vacancies and interstitials, with different charge states, in MgO. The calculated properties were the relaxed configurations, the Frenkel defect formation energies and th

In this paper we present the results of a molecular simulation study of low dosage anti-freeze agents for two common problems that occur during oil and gas transport: gas hydrate crystallization and wax deposition. Direct molecular dynamics simulatio

The role of poly(octadecyl acrylate) in inhibiting wax formation and growth has been examined using both molecular dynamics and Monte Carlo methods. The simulations show that the defective wax growth identified in earlier studies4,6 has a simple ener

The interactions between octamer units of a known wax inhibitor (poly(octadecyl acrylate)) and paraffin crystal surfaces are studied using molecular dynamics techniques. An inhibited surface is formed by adsorbing an octamer in a low energy configura

The results of density functional calculations of the interaction energies between Ag adatoms and dimers with a graphite surface are presented. It is found that, in agreement with STM experiments, the lowest energy position for the adatom is over a

The topic of this work is $3d$ transition metals deposited on a graphite surface. Spin-polarized density-functional calculations are used to obtain the magnetic moments of deposited adatoms and dimers and also their preferred position on the surface.
