With gasoline prices still hovering near $4 per gallon, scientists at Brookhaven Lab s Center for Functional Nanomaterials (CFN) are helping to develop electric vehicles capable of driving hundreds of miles on a single charge. A new compound of five tin atoms and one iron atom (FeSn
5) created at the CFN is another development along the road to higher capacity lithium-ion batteries for those vehicles of the future.
Compared to other types of rechargeable batteries, lithium-ion batteries weigh less, can store more electricity for longer periods of time, and can handle more cycles of use and recharging. They are used in some electric cars today, but are not yet powerful enough to compete with cars that can travel 300-400 miles on a single tank of gasoline.

Better understanding plastics underlying chemistry may revolutionize how we use these ubiquitous materials

Too much natural gas. A small adjustment to an experiment. These ingredients came together to produce one of the most influential materials ever invented.
Researchers at Berkeley Lab s Molecular Foundry user facility developed a polymer that they can break down and recreate. It could lead to cyclical plastics that can be recycled over and over again.

In the wake of World War II, companies were left with excess fossil fuels with no war to consume them. Looking to turn extra natural gas into liquid fuel, the Philips Petroleum Company hired chemists J. Paul Hogan and Robert L. Banks. As they experimented with turning natural gas into gasoline, they tweaked their catalyst - a material used to speed up chemical reactions. They expected it would make a liquid. Instead, the process produced something enti
