objective: maintaining the health of oral tissues is a major goal in dentistry. however, limitations in dental materials, instruments, procedures and medications prevent achievement of this goal. advances in nanotechnology have paved the way to approach this goal. this study reviews the advances on nanotechnology in dentistry. review of literatures: in this review study, google scholar, pubmed,...

This study aimed to determine the aerosolization behavior of a nanodispersion of budesonide, prepared using microfluidic reactors. The size and morphology of budesonide nanoparticles were characterized by photon correlation spectroscopy (PCS) and transmission electron microscopy (TEM). Processing/formulation parameters for formation of the nanoparticles were studied to determine their effects o...

   In this research Fe-TiO2 nanocomposites with different molar ratios of Fe/Ti were prepared as nano-photocatalyst using a modified Sol-Gel process at ambient temperature. Crystallographic properties of nanocomposites were characterized by X-ray Diffraction (XRD). Surface morphology and mean particle size of nanocomposites were specified by Field Emission Scann...

Abstract Introduction: The present study aimed to investigate the radiation protection properties of silicon-based composites doped with nano-sized Bi 2 O 3 , PbO, Sm Gd WO 3, and IrO particles. Radiation shielding nanoparticles were investigated for first time in current study. Material methods: MCNPX (2.7.0) Monte Carlo code was utilized calculate linear attenuation coefficients single multi-...

Interlayer excitons (IXs) in 2D semiconductors have long lifetimes and spin-valley coupled physics, with a long-standing goal of single exciton trapping for valleytronic applications. In this work, we use nano-patterned graphene gate to create an electrostatic IX trap. We measure unique power-dependent blue-shift energy, where narrow linewidth emission exhibits discrete energy jumps. attribute ...
