Transforming waste heat into clean energy

Researchers use supercomputers to explore new materials for thermoelectric generation

03-May-2019

Do you feel the warmth coming off your computer or cell phone? That's wasted energy radiating from the device. With automobiles, it is estimated that 60% of fuel efficiency is lost due to waste heat. Is it possible to capture this energy and convert it into electricity? Researchers working in the ...

Nanodiamonds as photocatalysts

22-Oct-2018

Diamond nanomaterials are considered hot candidates for low-cost photocatalysts. They can be activated by light and can then accelerate certain reactions between water and CO2 and produce carbon-neutral "solar fuels". The EU project DIACAT has now doped such diamond materials with boron and shown ...
