New catalyst turns greenhouse gases into hydrogen gas

A new nanocatalyst that recycles major greenhouse gasses, such as carbon dioxide (CO2) and methane (CH4), into highly value-added hydrogen (H2) gas has been developed. This catalyst is expected to greatly contribute to the ...

ESA moves ahead on low-cost reusable rocket engine

ESA's Prometheus is the precursor of ultra-low-cost rocket propulsion that is flexible enough to fit a fleet of new launch vehicles for any mission and will be potentially reusable.

New thermodynamic framework for cells

Physicists at the University of Luxembourg have developed theoretical tools to analyze and optimize chemical engines ranging from simple chemical reaction networks to complex metabolic pathways.

Physicists create world's smallest engine

Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine—which, as a single calcium ion, is approximately ten billion times smaller than a car ...
