Surface plasmon coupled emission (SPCE) is a novel analytical technique in which the isotropic emission of a fluorophore is combined with the surface plasmon resonance of a Ag (or Au) thin film to yield highly directional emission from the so-called

Nanoparticles of Fe3O4 (core) were synthesized and some were covered with a thin layer of Au (shell) to create a core-shell structure. The dynamic magnetic properties were studied using a vector network analyzer. It was found that, at a given applied

Bismuth is a fascinating material system owing to its unusual Fermi surface topology, which depends on size and temperature. Theoretical calculations predict that Bi should undergo a semimetal-to-semiconductor transition as at least one of its dimens
