Pollution Reducer & Heat Generator

New technology from North Carolina State University and West Virginia University can reduce air pollutant emissions from some chicken and swine barns while also reducing their energy use by recovering and possibly generating heat. A proof-of-concept unit incorporates a biofilter and a heat exchanger to reduce ammonia emissions.

Self-Healing Electronics Could Reduce Waste

When one circuit within an integrated chip cracks or fails, the whole chip – or even the whole device – is a loss. University of Illinois engineers have now developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink.

Bacteria Engineered to Eat Switchgrass and Make Transportation Fuels

Researchers with DOE’s Joint BioEnergy Institute (JBEI) have engineered the first strains of Escherichia coli bacteria that can digest switchgrass biomass and synthesize its sugars into all three of those transportation fuels. The microbes are even able to do this without any help from enzyme additives.
