Benvenuti nell'Anagrafe della Ricerca d'Ateneo
La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.
EnglishIn this contribution, we present a non-conventional core-shell nanoparticle, named supersphere, for implementing optical devices whose performances cannot be easily achieved with conventional nanoparticles. Superspheres are solids with intermediate shape between a sphere and a cube, whose external boundaries are described by Lamè surface equation. Thanks to its particular shape, a core-shell supersphere resonates at a lower resonant frequency with respect to a conventional core-shell spherical nanoparticle with same electrical dimensions. Such a characteristic allows relaxing the fabrication constrains, i.e. extremely thin shells, typically required for making the conventional spherical core-shell nanoparticles to operate in the lowest region of the visible spectrum. Here, after having discussed the geometry and electrical response of a core-shell supersphere, we report some preliminary results on their successful employment in the implementation of three optical devices: a trasparent screen, a biosensor and a mantle cloak.
