Double origin of stochastic granular tribocharging
Jan Haeberle, André Schella, Matthias Sperl +2
The mechanisms underlying triboelectric charging have a stochastic nature. We investigate how this randomness affects the distributions of charges generated on granular particles d…
Charging changes contact composition in binary sphere packings
Andre Schella, Simon Weis, Matthias Schroeter
Equal volume mixtures of small and large polytetrafluorethylene (PTFE) spheres are shaken in an atmosphere of controlled humidity which allows to also control their tribo-charging.…
Influence of humidity on the tribo-electric charging and segregation in shaken granular media
André Schella, Stephan Herminghaus, Matthias Schröter
We study the effect of humidity on the charge accumulation of polymer granulates shaken vertically in a stainless steel container. The setup allows to control the humidity level fr…
Controlling strongly correlated dust clusters with lasers
Hauke Thomsen, Patrick Ludwig, Michael Bonitz +4
The most attractive feature of dusty plasmas is the possibility to create strong correlations at room temperatures. At the same time, these plasmas allow for a precise diagnostics…
