New catalyst addresses engine efficiency, emissions quandary

A catalyst being developed by researchers at the Department of Energy's Oak Ridge National Laboratory could overcome one of the key obstacles still preventing automobile engines from running more cleanly and efficiently.

Physicists observe magnetic 'devil's staircase'

(—Many hiking trails feature a "devil's staircase"—a set of steps that are often steep and difficult to climb. The devil's staircase is also the name of a mathematical function whose graph exhibits a jagged step-like ...

Video: Cobalt oxide superlattice

These individual particles of cobalt oxide have been engineered to form a superlattice or 3D mesh structure to improve their chemical activity, explains Giorgio Divitini.

Evolution of a bimetallic nanocatalyst

( —Atomic-scale snapshots of a bimetallic nanoparticle catalyst in action have provided insights that could help improve the industrial process by which fuels and chemicals are synthesized from natural gas, coal ...

Controlling thermal conductivities can improve energy storage

Controlling the flow of heat through materials is important for many technologies. While materials with high and low thermal conductivities are available, materials with variable and reversible thermal conductivities are ...
