Experiments and modeling of dust particle heating resulting from changes in polarity switching in the PK-4 microgravity laboratory
In microgravity, polarity switching heats PK-4 dust clouds and leaves them hot far longer than neutral drag predicts, likely by converting configurational electric energy into motion.
