New Pathway to Forming Hydrogen Storage Compounds

Scientists at the Carnegie Institution for Science have found that high pressure can be used to make a unique hydrogen-storage material. The researchers found that the normally unreactive, noble gas xenon combines with molecular hydrogen under pressure to form a previously unknown solid with unusual bonding chemistry.

NASA's Algae Bioreactor Licensed to Algae Systems, LLC

Earlier this year, NASA introduced an algae photo-bioreactor that grows algae in municipal wastewater to produce biofuel and a variety of other products. The NASA bioreactor is an Offshore Membrane Enclosure for Growing Algae (OMEGA), which won't compete with agriculture for land, fertilizer, or freshwater.

Microscopic Bubbles Clean Oil from Polluted Water

Small amounts of oil leave a fluorescent sheen on polluted water. Oil sheen is hard to remove, even when the water is aerated with ozone or filtered through sand. A University of Utah engineer has developed an inexpensive method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas - creating tiny bubbles that attack the oil so it can be removed by sand filters.

Algae as a High-Temperature Hydrogen Source

A team of researchers from the University of Tennessee, Knoxville and Oak Ridge National Laboratory have found that the inner machinery of photosynthesis can be isolated from certain algae and, when coupled with a platinum catalyst, is able to produce a steady supply of hydrogen when exposed to light.

Japan Wins Australia's Global Green Challenge

The "Tokai Challenger" solar car from Japan's Tokai University won the 3,000 kilometer Global Green Challenge race down the center of Australia. The Tokai Challenger maintained an average speed of over 100 kilometers per hour, or about 62 miles per hour, besting the winner of the previous four races - the Dutch Nuon Solar Team.

Detecting Airborne Mercury by Use of Polymer/Carbon Films

NASA's Jet Propulsion Laboratory has introduced another method for detecting airborne elemental mercury. When films made of certain polymer/carbon composites are exposed to air containing mercury vapor, their electrical resistances decrease by measurable amounts. The films can be operated and regenerated at mild temperatures.
