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.
