Trapping of Single Nano-Objects in Dynamic Temperature Fields
Marco Braun, Alois Würger, Frank Cichos
In this article we explore the dynamics of a Brownian particle in a feedback-free dynamic thermophoretic trap. The trap contains a focused laser beam heating a circular gold struct…
Thermo-osmotic flow in thin films
Andreas Bregulla, Alois Würger, Katrin Günther +2
We report on the first micro-scale observation of the velocity field imposed by a non-uniform heat content along the solid/liquid boundary. We determine both radial and vertical ve…
Do thermal diffusion and Dufour coefficients satisfy Onsager's reciprocity relation?
Alois Würger
It is commonly admitted that in liquids the thermal diffusion and Dufour coefficients \ and satisfy Onsager's reciprocity. From their relation to the cross-coefficie…
Comment on "Curvature capillary migration of microspheres" by N. Sharifi-Mood, I.B. Liu, K.J. Stebe, Soft Matter 11, 6768 (2015), arXiv:1502.01672
Alois Würger
In a recent paper, Sharifi-Mood et al. study colloidal particles trapped at a liquid interface with opposite principal curvatures . In the theory part, they claim tha…
Hydrodynamic boundary effects on thermophoresis of confined colloids
Alois Würger
We study hydrodynamic slowing-down of a particle moving in a temperature gradient perpendicular to a wall. At distances much smaller than the particle radius, , lubrication…
