Electrostatic interaction between colloidal particles trapped at an electrolyte interface
Arghya Majee, Markus Bier, S. Dietrich
The electrostatic interaction between colloidal particles trapped at the interface between two immiscible electrolyte solutions is studied in the limit of small inter-particle dist…
Collective thermoelectrophoresis of charged colloids
Arghya Majee, Alois Würger
Thermally driven colloidal transport is, to a large extent, due to the thermoelectric or Seebeck effect of the charged solution.We show that, contrary to the generally adopted sing…
Thermocharge of a hot spot in an electrolyte solution
Arghya Majee, Alois Wüurger
We discuss the thermoelectric properties of a locally heated micron-size volume in an electrolyte solution. We find that such a hot spot carries a net charge Q which, for an excess…
Charging of Heated Colloidal Particles Using the Electrolyte Seebeck Effect
Arghya Majee, Alois Würger
We propose a novel actuation mechanism for colloids, which is based on the Seebeck effect of the electrolyte solution: Laser heating of a nonionic particle accumulates in its vicin…
Flow pattern in the vicinity of self-propelling hot Janus particles
Thomas Bickel, Arghya Majee, Alois Würger
We study the temperature field and the resulting flow pattern in the vicinity of a heated metal-capped Janus particle. If its thickness exceeds about 10 nm, the cap forms an isothe…
Specific Salt Effects on Thermophoresis of Charged Colloids
Kyriakos A. Eslahian, Arghya Majee, Michael Maskos +1
We study the Soret effect of charged polystyrene particles as a function of temperature and electrolyte composition. As a main result we find that the Soret coefficient is determin…
