Neutron Imaging Reveals Lithium Distribution in Lithium-Air Electrodes
January 01, 2013 — Using neutron-computed tomography, researchers at the CG-1D neutron imaging instrument at Oak Ridge National Laboratory’s High Flux Isotope Reactor (HFIR) have successfully mapped the three-dimensional spatial distribution of lithium products in electrochemically discharged lithium-air cathodes.
Theory meets experiment: structure-property relationships in an electrode material for solid-oxide fuel cells
December 01, 2012 — Fuel cell technology is one potentially very efficient and environmentally friendly way to convert the chemical energy of fuels into electricity. Solid-oxide fuel cells (SOFCs) can convert a wide variety of fuels with simpler, cheaper designs than those used in liquid electrolyte cells.
ORNL researchers probe invisible vacancies in fuel cell materials
August 22, 2012 — Knowing the position of missing oxygen atoms could be the key to cheaper solid oxide fuel cells with longer lifetimes. New microscopy research from the Department of Energy's Oak Ridge National Laboratory is enabling scientists to map these vacancies at an atomic scale.
SNS Diffractometer puts the squeeze on methane hydrate cages, unraveling its high-pressure structure
March 01, 2012 — Imagine a robot sent out on the prowl on this energy hungry planet looking for methane, the principal component of what we call “natural gas” and probably the most abundant organic compound on earth.
Studying how a protein's dynamics can take down a killer
March 01, 2012 — In the 1950s at Minimata, Japan, 900 people died and 2 million suffered life-long injury, in the form of birth defects to incapacitating neurological and muscular deformities, after swimming in and consuming fish from the bay nearby.
