Given their huge potential, more than 60 nanotechnology research groups worldwide have now begun to develop triboelectric nanogenerators (TENGs) for harvesting energy from mechanical vibrations. TENGs convert ambient mechanical energy into electricity for …Lire la suite
Researchers from the University of Rostock and Technion Haifa have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows optical signals to wind around the surface of a synthetic lattice while keeping it protected from scattering.
Their discovery has recently been published in the journal Nature (« Photonic topological insulator induced by a dislocation in three dimensions »).
