The Quincke effect is an electrohydrodynamic instability which gives rise to a torque on a dielectric particle in a uniform DC electric field. Previous studies reported that a sphere initially resting on the electrode rolls with steady velocity. In this thesis I report the experimental discovery of another regime, where...
Many phenomena that occur in the nanoscale, such as the self-assembly of charged amphiphiles, the metal extraction for recovering rare earth elements and nuclear waste as well as water purification, are driven by the electrostatic forces. Although current simulation techniques can handle the long-range Coulomb potential efficiently, the inhomogeneity in...
I present research in systems of biomedical relevance consisting of agents near or com- prising surfaces using computational approaches. The research topics include formation of bacterial biofilms, behavior of charged species near stacked, like-charged lamellae, and the the conformational behavior of lamellae with strong self-attraction.
In chapter 2, I present...
