Clathrates are crystals in which host atoms are enclosed in cage-like spaces. Recent work at the Vienna University of Technology with clathrates made of barium, silicon and gold, encapsulating single cerium atoms, has highlighted the novel thermoelectric properties of these materials. The group hopes that clathrates can be applied to harvest industrial waste heat into valuable electrical energy.
