• Fluid sensitive nanoscale switching with quantum levitation controlled by a-Sn/b-Sn phase transition 

      Boström, Anders Mathias; Dou, Maofeng; Malyi, Oleksandr; Parashar, Prachi; Parsons, Drew F.; Brevik, Iver Håkon; Persson, Clas (Journal article, 2018)
      We analyze the Lifshitz pressure between silica and tin separated by a liquid mixture of bromobenzene and chlorobenzene. We show that the phase transition from semimetallic α−Sn to metallic β−Sn can switch Lifshitz forces ...
    • How square ice helps lubrication 

      de Wijn, Astrid S.; Pettersson, Lars G M (Journal article, 2017)
      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 thermal equilibration of the confined water is ...
