Nanotechnology Now Our NanoNews Digest Sponsors Home > Press > Researchers analyzed circulating currents inside gold nanoparticles: A new method facilitates accurate analysis of magnetic field effects inside complex nanostructures The atomic structure of a gold nanoparticle protected by phosphine molecules (left) and magnetic-field-induced electron currents in a plane intersecting the center of the particle (right). The total electron current consists of two (paratropic and diatropic) components circulating in opposite directions. CREDIT University of Jyväskylä/Omar Lopez Estrada Abstract: ...
