PHYSORG.COM reported today that Lehigh University researchers have developed a cost-effective technique for reducing mercury emissions from coal-fired power plants. The reductions were reportedly achieved by modifying the physical conditions of power-plant boilers, including flue gas temperature, the size of the coal particles that are burned, the size and unburned carbon level of the fly ash, and the fly ash residence time. The modifications promote the in-flight capture of mercury. See "Boiler modifications cut mercury emissions."
In another article they reported that researchers at the University of Wisconsin had developed tiny lithium ion batteries with a lifetime of 12 years for use in implantable medical applications. Using organosilicon compounds, the team has developed a generation of rechargeable lithium ion batteries with lifetimes more than twice as long as current medical device batteries.
