Funding for Algal and Advanced Biofuels

The U.S. Department of Energy announced the availability of up to $85 million toward the development of algae-based biofuels and advanced, infrastructure-compatible biofuels. DOE seeks to bring together leading scientists and engineers from universities, private industry, and government to develop new methods to bring new biofuels to market.

Mercury Rises With Summer Heat

Smog is made up of an array of air pollutants, including mercury. One Ryerson University researcher has found that summer is the peak season for this atmospheric toxin, and that higher levels of mercury species exist in the urban atmosphere as compared to rural regions.

Capturing Carbon Dioxide In A Bowl

The accidental discovery of a bowl-shaped molecule that pulls carbon dioxide out of the air could offer new possibilities for dealing with global warming, including genetically engineering microbes to manufacture these CO2 “catchers.”

NASA Satellite Survey Reveals Dramatic Arctic Sea Ice Thinning

Arctic sea ice thinned dramatically between the winters of 2004 and 2008, with thin seasonal ice replacing thick older ice as the dominant type for the first time on record. The new results, based on data from a NASA Earth-orbiting spacecraft, provide further evidence for the rapid, ongoing transformation of the Arctic's ice cover.

Chemochromic Hydrogen Leak Detectors

Because hydrogen is odorless and colorless and poses an explosion hazard, there is an emerging need for sensors to quickly and accurately detect low levels of leaking hydrogen in fuel cells and other advanced energy-generating systems in which hydrogen is used as fuel. Simple, color-changing sensors have been invented.

Microstrip Antenna for Remote Sensing of Soil Moisture and Sea Surface Salinity

A compact, lightweight, dual- frequency antenna feed can benefit future soil and ocean studies by lowering mass, volume, and cost of the antenna system. The microstrip array design enables combined radar and radiometer instrumentation for satellite or airborne remote sensing.

Monitoring Plutonium Contamination

Five years from now, scientists will be able to better determine how, when, and why plutonium moves in soil and groundwater. The way to predict how plutonium is transported in groundwater away from a site is by looking at the dominant geochemical processes that control plutonium's (Pu) behavior in the subsurface at environmental levels. But that isn't always so easy.
