Violation of triboelectric charge conservation on colliding particles
arXiv:2111.13416 · doi:10.1103/PhysRevE.104.L022601
Abstract
In microgravity experiments, we quantified the net charge on systems of two identical, 434 \textmu m diameter glass spheres before and after a collision. We find that charge conservation is significantly violated. Independent of the sign of the total charge, the systems regularly lose some of their net charges, that is, they slightly discharge. This implies that positive as well as negative charge carriers become entrained into the surrounding atmosphere during a collision.
