Summary:
In a finding that may help speed the production of ultra-clean fuel cell vehicles powered by hydrogen, scientists in Michigan are reporting development of a sponge-like nanomaterial with a record-high surface area for holding gases. Just 1/30th of an ounce of the material has the approximate surface area of a football field.

In a finding that may help speed the production of ultra-clean fuel cell vehicles powered by hydrogen, scientists in Michigan are reporting development of a sponge-like nanomaterial with a record-high surface area for holding gases.

Just 1/30th of an ounce of the material has the approximate surface area of a football field.

Adam Matzger and colleagues note in the new study that scientists have tried for years to find a material to optimize hydrogen storage in futuristic fuel cell vehicles. Despite identifying several promising materials, researchers have been unable to meet the hydrogen storage goals proposed by the U.S. Department of Energy (DOE) for hydrogen fuel cell vehicles, they state.

They describe development of a highly-porous nanomaterial with an unprecedented ability to absorb gases that may help meet DOE's target. Called University of Michigan Crystalline Material-2 (UMCM-2), it consists of zinc oxide nanoclusters — each about 1/50,000 the width of a human hair — linked together by organic materials to generate a robust porous framework.

The scientists showed that UMCM-2 has a surface area exceeding 5,000 square meters per gram which is, they say, the highest value ever achieved.

Crude Oil Prices Bounce Back After Falling Below $100 a Barrel

TheStreet (July 16, 2014) Oil Futures are bouncing back after tumbling below $100 a barrel for the first time since May yesterday. Jeff Grossman is the president of BRG Brokerage and trades at the NYMEX. Grossman tells TheStreet the Middle East is always a concern for oil traders. Oil prices were pushed down in recent weeks on Libya increasing its production. Supply disruptions in Iraq fading also contributed to prices falling. News from China's economic front showing a growth for the second quarter also calmed fears on its slowdown. Jeff Grossman talks to TheStreet's Susannah Lee on this and more on the Energy Department's Energy Information Administration (EIA) report. Video provided by TheStreet
