Monte Carlo particle transport calculations for thick shielding problems can require very long run times in order to achieve an acceptable level of uncertainty (variance) in the final answers.

The Materials Science and Technology Division at Oak Ridge National Laboratory (ORNL) is seeking a candidate to fill a postdoctoral position in the field of nanomaterials synthesis and processing by ...

ORNL’s Educational Assistance Office is now separate from the Energy Systems EA office. The separation, however, won’t affect the normal processes of the system its users have been accustomed to, says ...

Idea: How can we direct the self-assembly of conducting polymers, and what are the optimal nanophase architectures for improved charge transport? • PS-b-P3HT diblock copolymers with insulating PS ...

What is a radiant barrier? Radiant barriers are materials that are installed in buildings to reduce summer heat gain and winter heat loss, and hence to reduce building heating and cooling energy usage ...

Have heating and cooling effects been tested? At present, there is no standardized method for testing the effectiveness of radiant barriers in reducing heating and cooling bills. But numerous field ...

Estimates Cooling and Heating Savings for Flat Roofs with Non-Black Surfaces ...

Adding more insulation where you already have some, such as in an attic, will save energy. You can save even greater amounts of energy if you install insulation into ...

If you are buying or building a new house, make sure that energy-saving features are included. The Federal Trade Commission (FTC) home insulation rule requires the seller of a new home to provide ...
