Stability of liquid ridges on chemical micro- and nanostripes
S. Mechkov, M. Rauscher, S. Dietrich
We analyze the stability of sessile filaments (ridges) of nonvolatile liquids versus pearling in the case of externally driven flow along a chemical stripe within the framework of…
Colloids dragged through a polymer solution: experiment, theory and simulation
Christof Gutsche, Friedrich Kremer, Matthias Krüger +3
We present micro-rheological measurments of the drag force on colloids pulled through a solution of lambda-DNA (used here as a monodisperse model polymer) with an optical tweezer.…
A dynamic density functional theory for particles in a flowing solvent
Markus Rauscher, Alvaro Dominguez, Matthias Krueger +1
We present a dynamic density functional theory (dDFT) which takes into accou nt the advection of the particles by a flowing solvent. For potential flows we can use the same closure…
Motion of nanodroplets near chemical heterogeneities
A. Moosavi, M. Rauscher, S. Dietrich
We investigate the dynamics of nanoscale droplets in the vicinity of chemical steps which separate parts of a substrate with different wettabilities. Due to long-ranged dispersion…
