Nowadays, progress in direct absorption solar collectors requires further investigations to realize heat transfer occurring a horizontal annulus cavity exposed external from different angles. An filled with nano-fluid is numerically simulated by using Ansys-Fluent for Rayleigh number equals 105. The wall of two-dimensional model the equally divided into six parts simulate heating isothermal wal...

We report a refractive index sensor comprising unique T-grating on top of periodic nano-cavities. The has two resonant modes sensitive to different regions the structure with low inter-region interference, hence allowing simultaneous detection analytes or more accurate single analyte. also provides self-referencing feature for broad range indices, from 1.3 1.5. Using finite difference time doma...

OBJECTIVES The purpose of this study was to compare the marginal and internal fit of nano-composite CAD-CAM restorations. MATERIALS AND METHODS A full veneer crown and an mesio-occluso-distal (MOD) inlay cavity, which were prepared on extracted human molars, were used as templates of epoxy resin replicas. The prepared teeth were scanned and CAD-CAM restorations were milled using Lava Ultimate...

Despite uses of titanium dioxide (TiO2) particles in various consumer and medical products therapy increasing human daily exposure, little studies were conducted on its cardiotoxicity. Thus, this study was designed to investigate the possible modulation of nanoTiO2 induced genotoxicity, mutagenicity and apoptosis by chlorophyllin (CHL) coadministration in mice cardiac cells. Mice were injected ...

We present an optical mode solver for a whispering gallery resonator coupled to an adjacent arbitrary shaped nano-particle that breaks the axial symmetry of the resonator. Such a hybrid resonator-nanoparticle is similar to what was recently used for bio-detection and for field enhancement. We demonstrate our solver by parametrically studying a toroid-nanoplasmonic device and get the optimal nan...

Rare-earth-ion doped crystals are state-of-the-art materials for optical quantum memories and quantum transducers between optical and microwave photons. Here we describe our progress towards a nanophotonic quantum memory based on a rare-earth (Neodymium) doped yttrium orthosilicate (YSO) photonic crystal resonator. The Purcell-enhanced coupling of the 883 nm transitions of Neodymium (Nd) ions t...
