Making molecular hydrogen more efficiently

When it comes to the industrial production of chemicals, often the most indispensable element is one that you can’t see, smell, or even taste. It’s hydrogen, the lightest element of all.

Harnessing Hotspots

Electronic devices often develop ‘hot spots’ that can become detrimental to performance. Much research has focused on developing methods to cool the system, or, even better, convert the excess heat to electricity by exploiting the thermoelectric effect — where a thermal gradient induces the movement of charge carriers.

Converting the energy of waste heat occurring in integrated circuits

The heat which occurs in tiny computer processors might soon be no longer useless or even a problem. On the contrary: It could be used to switch these processors more easily or to store data more efficiently!
