In power energy distribution networks, switchgear is considered critical equipment. This is
because the act of monitoring the operation and condition of switchgear, as well as …

The damaging effects of corona faults have made them a major concern in metal-clad
switchgear, requiring extreme caution during operation. Corona faults are also the primary …

We introduce collisions of solids as a new and efficient ionization mechanism for gas in
protoplanetary discs, which especially operates in the dense midplane of protoplanetary …

In microgravity experiments, we quantified the net charge on systems of two identical, 434-μ
m-diameter glass spheres before and after a collision. We find that charge conservation is …

Grain collisions in aeolian events, eg, due to saltation, result in atmospheric aerosols. They
may regularly be electrically charged, but individual charge balances in collisions including …

Ionization is important for magnetohydrodynamics and chemistry in protoplanetary discs but
known ionization sources are often weak along the mid-plane. We present, for the first time …

In recent years, collisional charging has been proposed to promote the growth of pebbles in
early phases of planet formation. Ambient pressure in protoplanetary discs spans a wide …

We present a method for measurements of electric dipole moments on (sub)-mm size
(basalt) particles levitated in an acoustic trap and centered within a plate capacitor. If an …

Martian dust storms in the planetary boundary layer share many qualitative similarities to
terrestrial sandstorms. Both of these turbulence-driven, particle-laden boundary layer flows …
