Ionic thermoelectric materials and devices
Dan Zhao, Alois Würger, Xavier Crispin
The tremendous amount of wasted heat from solar radiation and industry dissipation has motivated the development of thermoelectric concepts that directly convert heat into electric…
On the thermopower of ionic conductor and ionic capacitors
Alois Würger
We theoretically study the thermoelectric response of ionic conductors to an applied temperaturegradient. As a main result we find that open and closed systems with respect to char…
Visco-elastic drag forces and crossover from no-slip to slip boundary conditions for flow near air-water interfaces
Abdelhamid Maali, Rodolphe Boisgard, Hamza Chraibi +3
The "free" water surface is generally prone to contamination with surface impurities be they surfactants, particles or other surface active agents. The presence of such impurities…
Self-diffusiophoresis of Janus particles in near-critical mixtures
Alois Würger
We theoretically study the self-propulsion of a laser-heated Janus particle in a near critical waterlutidine mixture, and relate its velocity vp and squirmer parameter \b{eta} to t…
Thermally driven Marangoni surfers
Alois Würger
We study auto-propulsion of a interface particle, which is driven by the Marangoni stress arising from a self-generated asymmetric temperature or concentration field. We calculate…
Is Soret equilibrium a non-equilibrium effect?
Alois Würger
Recent thermophoretic experiments on colloidal suspensions revived an old debate, namely whether the Soret effect is properly described by thermostatics, or necessarily requires no…
