Experiments prove nanoscale metallic conductivity in ferroelectrics

(Science Daily) The prospect of electronics at the nanoscale may be even more promising with the first observation of metallic conductance in ferroelectric nanodomains by researchers at Oak Ridge National Laboratory..."This finding unambiguously identifies a new conduction channel that percolates through the insulating matrix of the ferroelectric, which opens potentially exciting possibilities to 'write' and 'erase' circuitry with nanoscale dimensions," said lead author Peter Maksymovych of ORNL's Center for Nanophase Materials Sciences...1/9

Plan to watch the Super Bowl? UT professor Yilu Liu will watch how much electricity you use.

(Tennessee Alumnus) ...as millions of Americans settled in front of their TVs, UT Knoxville professor Yilu Liu focused, instead, on her computer screen. While the Green Bay Packers and Pittsburgh Steelers vied for the Super Bowl title in Cowboys Stadium, Liu charted the gains and losses occurring not on the field but along the millions of miles of wire that make up the U.S. power grid. Liu is the UT-Oak Ridge National Laboratory Governor’s Chair for power systems in the College of Engineering...12/14
