Scientists have discovered that water moving over surfaces generates significantly more electrical charge than previously believed, particularly when it sticks and then slips past tiny obstacles. This ...

Like the original, this project drops water past strobing RGB LEDs creating ... Everything from circuit and PCB design to 3D printing to assembly is shown along with narration describing what ...

onto a droplet of distilled water. The peak power of the laser pulses was varied over the range of 1–25 GW. The droplet emission was measured by a spectrometer in the wavelength range of 195 ...

However, water generating an electrical charge when moving across surfaces is a less-known phenomenon. In a new study, ...

The new understanding of this "stick-slip" motion of water over a surface paves the way for surface design with controlled ...
