Nanofibers yield stronger, tougher carbon fiber composites
For more than 50 years, scientists have debated what turns particular oxide insulators, in which electrons barely move, into metals, in which electrons flow freely.
When Orlando Rios first started analyzing samples of carbon fibers made from a woody plant polymer known as lignin, he noticed something unusual. The material’s microstructure -- a mixture of perfectly spherical nanoscale crystallites distributed within a fibrous matrix -- looked almost too good to be true.
The Department of Energy’s Oak Ridge National Laboratory concluded a series of workshops this month that engaged scientists from around the country to identify grand scientific challenges and how they might be addressed through application of neutron science.
Neutron scattering research at the Department of Energy’s Oak Ridge National Laboratory has revealed clear structural differences in the normal and pathological forms of a protein involved in Huntington’s disease.
The Spallation Neutron Source at the Department of Energy’s Oak Ridge National Laboratory broke records for sustained beam power level as well as for integrated energy and target lifetime in the month of June.
The American Conference on Neutron Scattering returned to Knoxville this week, 12 years after its inaugural meeting there in 2002.
