  "summary": "Whether on a windowpane at home or during the industrial cleaning of computer chips: droplets sliding over solid surfaces become electrically charged. Yet the physical mechanism behind this charging remains a subject of debate. This charging is usually attributed to the exchange of charged particles (ions) at the interface between the droplet and the surface.",
