1. 1. A theoretical study of magnetism and its extension to finite temperatures in random alloys

   Författare :Fan Pan; Lars Bergqvist; Richard Evans; KTH; []
   Nyckelord :Fysik; Physics;

   Sammanfattning : This work presents new theoretical developments of atomistic spin simulations of magnetic materials at finite temperatures. Special focus is put on the description of longitudinal magnetic fluctuations and the application in random transition metal alloys. LÄS MER

3. 2. Gilbert damping of doped permalloy from first principles calculations

   Författare :Fan Pan; Lars Bergqvist; Peter Svedlindh; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gilbert damping; DFT; Permalloy; SPR-KKR; Spin stiffness; Fysik; Physics;

   Sammanfattning : The dynamic process of how fast a spintronic device can be switched from one state to another is characterized by the Gilbert damping parameter. It has been found that the Gilbert damping along with other intrinsic properties in permalloy, can be tuned by different dopants and doping concentration. LÄS MER

4. 3. The Mussel Adhesive Protein (Mefp-1) : A GREEN Corrosion Inhibitor

   Författare :Fan Zhang; Jinshan Pan; Douglas C. Hansen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon steel; mussel adhesive protein; Mefp-1; inhibitor; adsorption; film forming; complexation; cross-linking; ceria nanoparticle; composite film; EIS; AFM; QCM-D; ATR-FTIR; Confocal Raman Micro-spectroscopy; DFT calculation;

   Sammanfattning : Corrosion of metallic materials is a natural process, and our study shows that even in an alkaline environment severe corrosion may occur on a carbon steel surface. While corrosion cannot be stopped it can be retarded. LÄS MER
