The superresonance effect for a hollow dielectric sphere is numerically simulated with the Mie theory. It shown first time that weakly dissipative mesoscale spheres an air-filled cavity exhibit high-order Fano resonance related to internal modes. Superresonance in achieved by accurate choice of radius, while monolithic sphere, it ensured outer diameter particle under study. In this case, relati...

A thermoelectric generator (TEG) is studied by considering different leg structures of hollow/filled legs, using new cooling nanofluids, and analyzing the segmentation effect. TEG performance characterized power output, conversion efficiency, exergy efficiency. This study shows impact nanofluids (TiO2, graphene, Al2O3) on generator. Furthermore, in comparative analysis nanofluid enhancement for...

The use of TiO2 nanoparticles in organic-based photocatalytic coatings imposes several challenges: poor activity under visible light, binder photo-degradation, need for UV activation and toxicity concerns. Here we present a scalable two-step synthesis route to prepare TiO2-based hollow microspheres (HoS) as alternative photocatalyst commercial nanoparticles. or WO3-doped (3 mol% WO3) are synthe...

We study the response and cross sections for the absorption of GW energy generated in a Jordan-BransDicke theory by a resonant mass detector shaped as a hollow sphere. As a source of the GW we take a binary system in the Newtonian approximation. For masses of the stars of the order of the solar mass, the emitted GW sweeps a range of frequencies which include the first resonant mode of the detec...
