“You cannot have freedom without a rule of law ... and if you don't have it, what you tend to get is corruption and that is death to freedom, it's death to truth, it's death to honour, it's death to democracy.”
Margaret Thatcher, 1 October 1996.

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.
