Electrode could cut aluminum costs

Article Abstract:

An anode that could reduce aluminum smelting costs by one-fourth and air pollution by half has been developed by researchers at the Ohio State University in Columbus. The anode concept substitutes zirconia tubes that carry natural gas for carbon during the smelting process. An applied DC voltage draws oxygen through the tubes to oxidize the natural gas. It is expected to cut carbon dioxide production by half, use 40% less energy and eliminate fluorocarbon production.

Cutting costs for cutting NOx

Article Abstract:

Entropy Technology and Environmental Consultants Inc, headquartered in Houston, TX, has developed a new system for controlling nitrogen oxide emissions from gas- and low-sulfur-oil-fired combustion systems. The company claims that this system, called induced flue-gas recirculation, is more cost-effective than conventional flue-gas recirculation (FGR) because it does not require a separate FGR fan and wind box mixing devices.

Chemical "nose" could sniff out landmines

Article Abstract:

Researchers at Massachussetts Institute of Technology are developing new types of polymers that could detect landmines the way dogs do. The new chemicals are fluorescent polymers that are engineered to spot vapors of TNT and its derivatives. A simple, low-cost, portable device using the new fluorescent polymers is currently being tested. The device has also potentials for other applications, according to the researchers.
