Nonadiabatic Spin Torque Investigated Using Thermally Activated Magnetic Domain Wall Dynamics

Matthias Alexander Eltschka

Using transmission electron microscopy, we investigate the thermally activated motion of domain walls (DWs) between two positions in Permalloy (Ni80Fe20) nanowires at room temperature. We show that this purely thermal motion is well described by an Arrheni ...

An Atomistic Simulation Method for Oxygen Impurities in Aluminium Based on Variable Charge Molecular Dynamics

Andreas Elsener

Impurities are known to have a significant impact on materials properties. In particular, the presence of impurities can change mechanical properties and stabilize the microstructure by reducing grain growth and recrystallization processes. In the past ato ...

Effect of electrode potential on the tribocorrosion of tungsten

Michel Declercq, Didier Bouvet, Stefano Mischler, Jelena Stojadinovic

The tribocorrosion behavior of tungsten sliding against an alumina ball was evaluated in sulfuric acid under applied electrode potential. Surface chemistry of worn and unworn surfaces was evaluated using XPS and AES. Quasi-potentiostatic polarization curve ...

Collaboration and abstract representations: towards predictive models based on raw speech and eye-tracking data

Pierre Dillenbourg, Patrick Jermann, Mirweis Sangin, Marc-Antoine Nüssli

This study aims to explore the possibility of using machine learning techniques to build predictive models of performance in collaborative induction tasks. More specifically, we explored how signal-level data, like eye-gaze data and raw speech may be used ...

Effect of interatomic potential on the behavior of dislocation-defect interaction simulation in α-Fe

Seyed Masood Hafez Haghighat

Molecular dynamics simulation is one of the most useful methods to model defect generation and subsequent change in mechanical properties in material that will suffer irradiation in the future fusion reactors. This work is aimed at showing the influence of ...

Proteins in Mesoporous Silicates

Liang Qiao, Yun Liu

Mesoporous silicates (MPS) provide a means of immobilizing proteins and enzymes in a stable environment while retaining physiological function. A systematic methodology of assessing the potential of immobilising a given protein on to MPS has been developed ...
