1. Describing Interstitials in Close-packed Lattices: First-principles Study
Abstract : Describing interstitial atoms in intermetallics or simple mono-atomic close-packed metals is a straightforward procedure in common full-potential calculations. One establishes a sufficiently large supercell, introduces the interstitial impurity and performs the electronic structure and total energy calculation. READ MORE

2. Laboratory studies of forbidden decay processes in stored ions
Abstract : Measurements of atomic and ionic data has been an active research area since the beginning of spectroscopic studies. The experimental data deduced from thesestudies are of great interest for our understanding of fundamental as well as applied physics. READ MORE

3. Initial Oxidation Kinetics of Al(111): A Monte Carlo Study
Abstract : Almost all metals around us have a thin oxide layer on top of the bulk metal underneath. Often this oxide film protects the metal against further oxidation, or corrosion. Examples are the oxide film that makes stainless steel "stain-less" or the ones on titanium and aluminium alloys, which are very corrosion resistant. READ MORE

4. Properties of Al-Mg Alloys and Vacancies in Al: a First-Principles Investigation
Abstract : Phase transformations such as precipitation are used to control the strength of many technologically important aluminum alloys. In precipitation hardening, the material is heat treated and aged to produce precipitates, small particles of a different phase, in the matrix. READ MORE

5. Eutectic Modification of Al-Si casting alloys
Abstract : Aluminum alloys with silicon as the major alloying element are the most widely used aluminum casting alloys. The eutectic phase in these alloys is formed by hard and brittle silicon plates in an aluminum matrix. Such silicon plates can act as crack propagation paths deteriorating the toughness of the material. READ MORE
