Abstract: Synergies among multiple energy sectors in an integrated electricity and heat system (IEHS) improve energy efficiency, economic operation and renewable energy utilization, thus contributing ...

Researchers have developed experimental compounds that make cells burn more calories by subtly tweaking how mitochondria ...

An experiment with ultracold atoms reveals that a strongly driven quantum system doesn’t always heat up as expected. In daily ...
