Electrification at water–hydrophobe interfaces
Nature Communications, 2020 Electrification of water upon contact with hydrophobic surfaces is a ubiquitous but poorly understood phenomenon. Here, the authors pinpoint the factors responsible for the excess positive charge carried by water droplets dispensed from hydrophobic ...

Charge control experiments on a CH-53E helicopter in a dusty environment [PDF]
Charge control tests were carried out on a ground based, Marine Corps helicopter to determine if control of the electric fields acting on the engine exhaust gases could be used to reduce the electrification of the helicopter when it operated in a dusty ...

Static Electrification by Nonwetting Liquids. Contact Charging and Contact Angles
Langmuir, 1995 A glass slide hydrophobized with dimethyldichlorosilane appears to be electrostatically charged when a nonwetting liquid recedes from its surface. The surface charge has negative polarity. The density of the charge which arises on retraction from water is 10 -4 C/m 2 . The half-life of the charge on the surface in air is 0.5 h.

Achieving ultrahigh triboelectric charge density for efficient energy harvesting
Nature Communications, 2017 Triboelectric nanogenerators (TENGs) harvest ambient mechanical energy and convert it into electrical energy. Here, the authors couple surface polarization from contact electrification with dielectric polarization from a ferroelectric material in vacuum ...
