Abstract

A long-standing mystery in science is the process whereby charge spontaneously exchanges between different materials that are brought into contact. After thousands of years of study there is no ab initio theory of tribocharging. As such it is an area of R&D that is not yet tethered to the first principles of physics and is wide open for new inventions. In 2008, Camara et al at UCLA discovered that tribocharging in a moderate vacuum could be used to take X-ray images. Since then, we have improved the X-ray output by 6 orders of magnitude and controlled the emission for use in a commercial product. Here we present an overview of this technology for use in X-ray fluorescence and X-ray imaging.
