How square ice helps lubrication
Astrid S. de Wijn, Lars G. M. Pettersson
In the context of friction we use atomistic molecular-dynamics simulations to investigate water confined between graphene sheets over a wide range of pressures. We find that therma…
Emergent friction in two-dimensional Frenkel-Kontorova models
Jesper Norell, Annalisa Fasolino, Astrid S. de Wijn
Simple models for friction are typically one-dimensional, but real interfaces are two-dimensional. We investigate the effects of the second dimension on static and dynamic friction…
Imaging high-speed friction at the nanometer scale
Per-Anders Thorén, Astrid S. de Wijn, Riccardo Borgani +2
Friction is a complicated phenomenon involving nonlinear dynamics at different length and time scales[1, 2]. The microscopic origin of friction is poorly understood, due in part to…
