    • Experimental investigation of critical Casimir forces in binary liquid mixtures by blinking optical tweezers 

      Magazzu, Alessandro; Schmidt, F.; Callegari, Agnese; Gambassi, A.; Dietrich, S.; Volpe, Giovanni (OSA, 2017)
      We investigate, for the first time and by blinking optical tweezers, the effects of critical Casimir forces (CCFs) on the free dynamics of a pair of spherical colloidal particles, immersed in binary liquid mixtures upon ...
    • Microscopic engine powered by critical demixing 

      Schmidt, F.; Magazzu, Alessandro; Callegari, Agnese; Biancofiore, Luca; Cichos, F.; Volpe, Giovanni (OSA, 2017)
      We propose a new type of engine that is powered by the local, reversible demixing of a critical binary liquid. A microscopic particle is optically trapped and performs revolutions due to the emergence of diffusiophoresis.
