The Puzzling Collapse of Electronic Sliding Friction on a Superconductor Surface

, 1998
In a recent paper [Phys. Rev. Lett. 80 (1998) 1690], Krim and coworkers have observed that the friction force, acting on a thin physisorbed layer of N_2 sliding on a lead film, abruptly decreases by a factor of ~2 when the lead film is cooled below its ...

Embroidery Triboelectric Nanogenerator

E-Textiles 2023
The “Embroidery Triboelectric Nanogenerator” (E-TENG) is a wearable device that extracts energy from human motion by making use of the triboelectric phenomena, in addition to conductive fabric along with embroidery threads. One of the greatest ways to transform ambient vibrational energy from the human body is to use a wearable triboelectric energy ...
