Droplet manipulation has important applications in areas such as heat management, water harvesting, and chemical reactions. A research team from City University of Hong Kong (CityU) developed a ...

Triboelectric nanogenerators are an energy harvesting technology that relies on the coupling effects of contact electrification and electrostatic induction between two solids or a liquid and a solid.

While EMGs are based on Faraday's law of electromagnetic induction, suitable for large-scale power generation, PENGs can convert tiny physical deformations into electricity in self-powered, ...

Static electricity can be defined as a stationary charge that builds up on the surface of a material. The interaction between stationary charges, known as electrostatics, leads to two key problems: ...
