2. Adsorption of surface active elements on the iron (100) surface A study based on ab initio calculationsDetta är en avhandling från Stockholm : KTH
Sammanfattning : In the present work, the structural, electronic properties, thermodynamic stability and adatom surface movements of oxygen and sulfur adsorption on the Fe surface were studied based on the ab initio method.Firstly, the oxygen adsorbed on the iron (100) surface is investigated at the three adsorption sites top, bridge and hollow sites, respectively.

Sammanfattning : Utilization of remotely located sustainable energy resources such as solar, wind and hydro calls for further developments of long-distance electric power transmissions operating at ultra-high voltage (UHV) levels which may exceed 1000 kV ac and 800 kV dc utilized today. It is foreseen that insulation of such transmission systems is to be based on polymeric materials that can provide a number of technical benefits over traditionally used glass and porcelain based insulation.

Sammanfattning : Implant rehabilitation of edentulous patients is a predictable treatment with high long-term survival rates (90-95%) reported for the major dental implant systems after 5-10 years in function. Throughout recent years, different materials, implant surface technologies, macrodesigns, and surgical techniques have been developed to enhance osseointegration and lessen treatment timeframes, for example allowing immediate or early functional loading in patients with reduced bone density.
