A new use for old tires

(Knoxville News Sentinel) ...old tires could prove beneficial in upgrading lithium-ion batteries that are used to power plug-in vehicles. “By modifying the microstructural characteristics of carbon black, a substance recovered from discarded tires, a team led by Parans Paranthaman and Amit Naskar is developing a better anode for lithium-ion batteries...8/27

Scientists learn to control reactions with the shape of a rare-earth catalyst

(DOE Research News) Scientists at the Department of Energy's Oak Ridge National Laboratory have discovered they can control chemical reactions in a new way by creating different shapes of cerium oxide, a rare-earth-based catalyst. Their finding holds potential for refining fuels, decreasing vehicle emissions, producing commodity chemicals and advancing fuel cells and chemical sensors...8/27

HFIR’s fuel conversion seeming less likely

(Knoxville News Sentinel) ...The High Flux Isotope Reactor was built in the 1960s. That’s pretty old by reactor standards. But the HFIR has undergone a significant makeover in recent years — replacement parts, infrastructure upgrades and new research capabilities — and lab officials have stated their intention to operate the 85-megawatt reactor for decades to come...8/27
