Lithium ions flow through solid material

Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory, in collaboration with researchers from Purdue University and Rutgers University, have merged materials science and condensed matter physics ...

Genetically engineered yeast soak up heavy metal pollution

Environmental contamination with heavy metals is often the result of various types of industrial processes. Because heavy metals can be dangerous to humans and other wildlife, contaminated sites need to be cleaned up. This ...

Feather-light metal cathodes for stable lithium-oxygen batteries

Lithium-oxygen systems could someday outperform today's lithium-ion batteries because of their potential for high energy density. However, a number of important issues, such as their poor electrochemical stability must be ...

Porous, layered material can serve as a graphene analog

An electrically conductive material, with layers resembling graphene (single sheet of graphite), was synthesized under mild conditions using a well-known molecule that allows good electronic coupling of nickel ions and organic ...

Better batteries inspired by lowly snail shells

Scientists are using biology to improve the properties of lithium ion batteries. Researchers at the University of Maryland, Baltimore County (UMBC) have isolated a peptide, a type of biological molecule, which binds strongly ...
