Reentrant Network Formation in Patchy Colloidal Mixtures under Gravity

Daniel de las Heras
University of Bayreuth, Germany

Patchy colloids are particles with a solid core and a discrete number of interaction sites. In this seminar I will present simulation and theoretical results of a model binary mixture of patchy colloids under gravity. By tuning the buoyant masses of the colloids we can control the sequence of fluid stacks formed in sedimentation-diffusion-equilibrium. We find complex stacking sequences with up to four layers and reentrant network formation.

O despertar da bolha

Bolhas de ar e películas líquidas são de grande importância em áreas tão diversas como as indústrias mineira, transformadora e alimentar e a segurança de materiais, tendo ainda aplicações potenciais em micro e nanotecnologias.
