Microphysical effects of water content and temperature on the triboelectrification of volcanic ash on long timescales
Joshua Méndez Harper, Leah Courtland, Josef Dufek +1
The effects of water and temperature on the triboelectrification of granular materials have been reported by numerous authors, but have not been studied robustly in the context of…

Triboelectrification of KCl and ZnS particles in approximated exoplanet environments
Joshua Méndez Harper, Christiane Helling, Josef Dufek
When mobilized, granular materials become charged as grains undergo collisions and frictional interactions. On Earth, this process, known as triboelectrification, has been recogniz…
