Triboelectrification is an effect that is known to each and every one probably since ancient Greek time, but it is usually taken as a negative effect and is avoided in many technologies. We have recently invented a triboelectric nanogenerator (TENG) that is used to convert mechanical energy into electricity by a conjunction of triboelectrification and electrostatic induction. As for this …

· Water flowing through tubes of different materials acquires positive charge whose magnitude is correlated with the materials' position in the triboelectric series. However, water acquires negative charge when flowing through air but its charge is modified by applying an external electric field. Water is thus located at the top of the TS ...

· Triboelectric properties of materials play an essential role in liquid energy harvesting and emerging application.The triboelectric properties of materials can be controlled by chemical functionalization strategy, which can improve the utilization of liquid energy resources or reduce the hazards of electrostatic effects.Herein, the latest research progress in molecular …
· The triboelectric series is a list that ranks various materials according to their tendency to gain or lose electrons. It usually lists materials in order of decreasing tendency to charge positively (lose electrons), and increasing tendency to charge negatively (gain electrons). Somewhere in the middle of the list are materials that do not show ...
· The Triboelectric Effect or Triboelectric Charging is an electrostatic phenomena in which electric charge is transferred from one object to another object upon contact. Charge is transferred through the transfer of electrons, the direction of the transfer depending on the specific materials involved. The term triboelectric comes from Greek.Tribo (τρίβω) means "to rub" or …
