Deterministic transport of particles in a micro-pump
Philippe Beltrame, Peter Talkner, Peter Hänggi
We study the drift of suspended micro-particles in a viscous liquid pumped back and forth through a periodic lattice of pores (drift ratchet). In order to explain the particle drif…

Depinning of three-dimensional drops from wettability defects
Ph. Beltrame, P. Hänggi, U. Thiele
Substrate defects crucially influence the onset of sliding drop motion under lateral driving. A finite force is necessary to overcome the pinning influence even of microscale heter…
