ENERGY - Oxygen 'sponge' presents path to better catalysts, energy materials

Scientists at the Department of Energy's Oak Ridge National Laboratory have developed a new oxygen "sponge" that can easily absorb or shed oxygen atoms at low temperatures. Materials with these novel characteristics would be useful in devices such as rechargeable batteries, sensors, gas converters and fuel cells.
