Strain engineering allows design of materials with tailored properties. Here, the authors show that strain can be used to control atomic diffusion in Sb2Te3-GeTe superlattices, and they propose general design rules to enable atomic switching function

Phase change memory devices are typically reset by melt-quenching a material to radically lower its electrical conductance. The high power and concomitantly high current density required to reset phase change materials is the major issue that limits

Physical review B (PRB)

Molecular dynamics simulations of liquid and glassy selenium have been carried out using density functional (400-773 K, 600 atoms) and classical force field (290-500 K, 5488 atoms) methods. Structural features (structure factors, pair distribution fu

Steered molecular dynamics simulations of ligand–receptor interaction in lipocalins

Autor: Jaakko Akola, Janne Kalikka

Publikováno v: European Biophysics Journal. 40:181-194

Retinol binding protein (RBP) and an engineered lipocalin, DigA16, have been studied using molecular dynamics simulations. Special emphasis has been placed on explaining the ligand-receptor interaction in RBP-retinol and DigA16-digoxigenin complexes,
