Electrification of water interface [PDF]
Journal of Physics: Condensed Matter, 2021 Abstract The surface charge of a water interface determines many fundamental processes in physical chemistry and interface science, and it has been intensively studied for over a hundred years. We summarize experimental methods to characterize the surface charge densities developed so far: electrokinetics, double-layer force ...

Electrification of Liquid Drops [PDF]
Nature, 1949 IT has been known for some time that electrification is produced when water breaks into drops, one of the earliest observations being made by Lenard, who found charged drops in the vicinity of a waterfall. This phenomenon is of interest in many ways, one of the most important being in connexion with the production of thunderstorms.

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application
Advanced Engineering Materials, EarlyView.N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion
