Coupled self-charging and self-propulsion of evaporating sessile droplets
Nitish Singh, Aaron D. Ratschow, Syed N. R. Kazmi +1
Evaporating sessile water droplets universally deposit surface charges while simultaneously becoming self-charged---a phenomenon that remains under-appreciated despite its potentia…

Spontaneous Coulomb fissions of drops on lubricated surfaces
Marcus Lin, Peng Zhang, Aaron D. Ratschow +3
Charged water drops are more widespread than commonly acknowledged. For example, raindrops typically carry charges of order Q ~ 1 pC, while routine pipetting in the laboratory prod…

Bipolar surface charging by evaporating water droplets
Nitish Singh, Aaron D. Ratschow, Nabeel Aslam +1
Surface charging is a ubiquitous phenomenon with important consequences. On one hand, surface charging underpins emerging technologies such as triboelectric nanogenerators; on the…
