Detecting Contaminants in Water

Many organic contaminants in the air and in drinking water need to be detected at very low-level concentrations. Research published by the laboratory of Prashant V. Kamat, the John A. Zahm Professor of Science at the University of Notre Dame, could be beneficial in detecting those contaminants.

Bacteria Provide Cleanup of Oil Spills and Wastewater

NASA partnership leads to innovation on the microbial scale.Given the size of our planet and its wealth of resources, it is easy to forget that those resources are finite. As Earth’s human population continues to grow, the questions of how to effectively limit and recycle waste, avoid environmental contamination, and make the most of water and fuel reserves become all the more pressing.

New Materials May Cut Energy Costs for Carbon Capture

A study of over four million absorbent minerals has determined that industrial minerals called zeolites could help electricity producers slash as much as 30 percent of the parasitic energy costs associated with removing carbon dioxide from power plant emissions. The research was done by scientists at Rice University, UC Berkeley, Lawrence Berkeley National Laboratory, and the Electric Power Research Institute.

Technology Awarded for Improving Submarine Air Quality

Creators of a nanotech-based system that captures carbon dioxide from the atmosphere within a submarine while providing a more environmentally friendly removal process have won the Federal Laboratory Consortium Interagency Partnership Award for 2012. The technology — Self Assembled Monolayers on Mesoporous Supports, or SAMMS — is destined for incorporation into future submarines.

Copper-Gold Nanoparticles Efficiently Convert Carbon Dioxide

Copper is one of the few metals that can turn carbon dioxide into hydrocarbon fuels with relatively little energy, but it is temperamental and easily oxidized. MIT researchers have engineered nanoparticles of copper mixed with gold - which is resistant to corrosion and oxidation - making the copper much more stable. They coated electrodes with the hybrid nanoparticles and found that much less energy was needed for conversion.

Boosting Nanowires for Better Batteries and Solar Cells

Stanford University engineers have found a novel method for "decorating" nanowires with chains of tiny particles to increase their electrical and catalytic performance. The technique is simpler and faster than earlier methods and could lead to better lithium-ion batteries, more efficient thin-film solar cells, and improved catalysts that yield new synthetic fuels.

Using Electricity to Generate Alternative Fuel

Electrical energy generated by various methods can be difficult to store efficiently. Chemical batteries, hydraulic pumping, and water splitting suffer from low energy-density storage or incompatibility with current transportation infrastructure. UCLA researchers have demonstrated a method for storing electrical energy as chemical energy in higher alcohols, which can be used as liquid transportation fuels.
