New phase of solid carbon allows researchers to create tougher-than-tough diamonds at room temperature

By Stephanie Liverani / December 9, 2015

Researchers from North Carolina State University discovered a new phase of solid carbon that is harder than diamonds and can be formed at room temperature and at ambient atmospheric pressure.

Group shows hysteretic behavior of ferroelectric materials changes at nanoscale

By / May 20, 2010

A collaborative group of researchers from Oak Ridge National Lab, Penn State, the Univ. of Sheffield (U.K.) and EPFL (Switzerland) have made a discovery that overturns some 100-year-old assumptions about the behavior of polycrystalline and other ferroelectric materials. In brief, the nonlinear materials responses and associated enhanced electromechanical properties that occur at the microlevel stop…
