Contact electrification and triboelectric charging are areas of intense research. Despite their
low ability to accept or donate electrons, polymer insulator based triboelectric …

Triboelectric nanogenerators (TENGs) have been recognized as a key potential solution for
powering microdevices by converting mechanical energy and interfacial friction to electricity …

Triboelectrification necessitates a frictional interaction between two materials, and their
contact electrification is characteristically based on the polarity variance in the triboelectric …

Contact electrification is an interfacial process in which two surfaces exchange electrical
charges when they are in contact with one another. Consequently, the surfaces may gain …

Processes ranging from fracture of crystals to peeling of tape have been known for many
decades to emit light through a mechanism believed to be associated with electrical …

Nominally identical materials exchange net electric charge during contact through a
mechanism that is still debated.“Mosaic models,” in which surfaces are presumed to consist …

Contact electrification, or contact charging, refers to the process of static charge
accumulation after rubbing, or even simple touching, of two materials. Despite its relevance …

The polarization induced by an external electric field significantly influences the contact
charge of particles. It can easily cause solid–liquid–gas-like phase transitions in dense …

From colloid suspension to particle aggregation in protoplanetary formation, electrostatic
attraction and repulsion between particles is a key mechanism behind the aggregation and …

Once granular materials flow, particles charge because of the triboelectric effect. When
particles touch each other, charges are exchanged during contact whether they are made of …
