In 1840, James Prescott Joule submitted a paper to the Royal Society detailing his experiments on the heat generated by electric currents in metallic conductors. He proposed that this effect was proportional to the conductors' resistance and the square of the current's intensity. More recently, Liangbing Hu, a professor at the University of Maryland, utilized rapid Joule heating technology to prepare a variety of new nanomaterials, including nano-particle of high entropy alloys, stable single atoms, and high-performance catalysts (Nature 2022, 605:470; Science 2018, 359:1489; and Nature Nanotechnology 2019, 14:851). In 2020, James M. Tour, a professor at Rice University, developed a method using high-voltage capacitors for flash Joule heating that can produce gram-scale graphene in just one second from various cheap carbon powders, such as carbon black, waste plastic and rubber, and numerous metastable phase materials (Nature 2020; 577:647).

Saiyin Materials Co., LTD. has developed a series of Saiyin Joule heating system that incorporates both flash and rapid Joule heating methods. To date, numerous research groups have used this system to uncover a range of intriguing results.
