Common material such as polyethylene used in plastic bags could be turned into something far more valuable through a process being developed at the Department of Energy's Oak Ridge National Laboratory.
The Spallation Neutron Source's Powder Diffractometer POWGEN has launched a rapid access sample mail-in system for users who use the flexible general-purpose instrument for a wide range of structural studies of novel materials. The instrument will be made available to rapid access users for a few da...
An Oregon State University graduate student has successfully turned her participation in a two-day POWGEN Neutron Diffraction workshop at Oak Ridge National Laboratory's Spallation Neutron Source into a published paper in the Journal of Solid State Chemistry. Participants at the workshop in Septembe...
Considering how ubiquitous it is on earth, methane (natural gas) at the molecular level is a scientific unknown. To understand it and to manage it both as energy and as an environmental hazard, scientists need to know more about its molecular structure. A neutron diffraction study at the Spallation ...
Theoretical physicists have long predicted the existence of a quantum state of matter they call "supersolidity," in which solid helium-4 loses its viscosity and flows like a liquid. Researchers are using the Spallation Neutron Source in a series of studies to pin down whether this paradoxical new st...
Casein micelles in milk, stabilized by molecules of kappa-casein, are the building blocks of dairy products such as yogurt and cheese and the vehicle for delivering calcium phosphate to newborns. Several models for the internal structure of these have been proposed. Using contrast variation small-an...
Lessons about energy efficiency are hitting home through an online middle school pilot curriculum developed for students in Louisiana, Hawaii and Japan. The Biggest Energy Loser Challenge, created through a partnership among the Department of Energy, Oak Ridge National Laboratory and Southern Univer...
Determining with precision the carbon balance of North America is complicated, but researchers at Oak Ridge National Laboratory have devised a method that considerably advances the science. In developing their approach, a team led by Daniel Hayes of the Department of Energy's ORNL took advantag...
About 2,500 people still die each year in residential fires, but that number could be reduced with a smart fire alarm that can immediately distinguish between fires and nuisances. A team led by Oak Ridge National Laboratory's Bruce Warmack of the Measurement Science and Systems Engineering Division ...
The Journal of Condensed Matter Physics has put out a special issue on the dynamics of water and glass-forming liquids that features six ORNL neutron sciences research collaborations. The special issue focused on fluids and other soft condensed materials confined in matrices, a natural area for neut...
