KNOXVILLE—One of the key holdups in the march toward more efficient sustainable energy could soon be answered, thanks in part to researchers at the University of Tennessee in Knoxville.

The College of Engineering’s Alexander Papandrew and Gerd Duscher are part of a broader Oak Ridge National Laboratory-led team that recently received a $2.75 million U.S. Department of Energy grant for work on improving fuel cells, $1.4 million of which went to their project.

The basic premise of their work is to find a far more efficient way to turn chemical energy—in this case natural gas—into electrical energy. [Read more…]

Greener, cheaper fuel possible thanks to ORNL-UT breakthrough

KNOXVILLE—Sticker shock at the gas pump could soon be a thing of the past thanks to research being conducted by Oak Ridge National Laboratory and the University of Tennessee in Knoxville.

Among the key components in processing fuels, particularly bio-friendly ones, are the membranes that aid in the process of separating unwanted compositions such as water from the fuel or hydrocarbon from aqueous phase.

“We can help wallets and help profits at the same time,” said Michael Hu, a joint faculty member of ORNL and the College of Engineering’s Department of Chemical and Biomolecular Engineering. “If we can improve that separation process it will mean a reduction in cost to make, a reduction in cost to supply, and a reduction in cost to buy.”

The breakthrough technology being brought to life by the research team combines nanotextured pores with superhydrophobic or superhydrophillic—or, in plain terms, super water-repulsing and water-attracting—substances. [Read more…]
