Scientists have discovered the details of an unconventional coupling between a bacterial protein and a mineral that allows the bacterium to breathe when oxygen is not available. The research could lead to innovations in linking proteins to other materials for bioelectronic devices such as sensors that can diagnose disease or detect contaminants. ... Read more »
Rechargeable batteries based on magnesium, rather than lithium, have the potential to pack more energy into smaller batteries. However, researchers have discovered a surprising set of chemical reactions involving magnesium that degrade battery performance even before the battery can be charged up. ... Read more »
A powdery mix of metal nanocrystals wrapped in single-layer sheets of carbon atoms shows promise for safely storing hydrogen for use with fuel cells for passenger vehicles and other uses. Now, a new study provides insight into the atomic details of the crystals’ ultrathin coating and how it serves as selective shielding while enhancing their performance in hydrogen storage. ...

Researchers have observed, for the first time, an exotic 3-D racetrack for electrons in ultrathin slices of a tiny crystal they made at Berkeley Lab. ... Read more »
Hydrogen is the lightest and most plentiful element on Earth and could serve as a carbon-free, virtually limitless energy source. Recently, researchers working at the ALS and the Molecular Foundry developed a promising new materials recipe based on magnesium nanocrystals and graphene for a hydrogen fuel cell with improved performance in key areas.
