A new type of symmetry: How a tetrahedral substance can be more symmetrical than a spherical atom
(PHYSorg.com Nanotechnology)

Scientists at Tokyo Institute of Technology have theoretically demonstrated that special tetrahedron nanostructures composed of certain metals have a higher degree of symmetry than the geometrical symmetry of spherical atoms. Nanomaterials with unique and unprecedented electrical and magnetic properties arising from this symmetry will be developed and used for next-generation electronic devices.
