Researchers at the Department of Energy’s Oak Ridge National Laboratory have captured undistorted snapshots of refrigerants flowing through small heat exchangers, helping to further elucidate characteristics of heat transfer.

Through drought and flood, winter freeze and summer heat, and the occasional deer nibble or beaver gnaw, trees stand sturdy. Partly, trees can thank genetic makeup, refined through millennia, for the ability to overcome much of what Mother Nature hurls their way.

Inadequate insulation is one of the largest causes of wasted energy, quickly allowing comfortable heating or cooling to disperse air outside.

A composite foam insulation panel being developed by Oak Ridge National Laboratory and partners could reduce wall-generated heating and cooling loads in buildings by 38 to 50 percent, potentially saving homeowners $150 or more per year. The proposed 2-inch board will feature modified atmosphere insu...
