Cheap hybrid outperforms rare metal as fuel-cell catalyst

(Phys.org) —Graphene quantum dots created at Rice University grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, making them better ...

Chromium's bonding angles let oxygen move quickly

By taking advantage of the natural tendency of chromium atoms to avoid certain bonding environments, scientists at DOE's Pacific Northwest National Laboratory have generated a material that allows oxygen to move through it ...
