Effect of Interfacial Polarization and Water Absorption on the Dielectric Properties of Epoxy-Nanocomposites

Five types of nanofillers, namely, silica, surface-silylated silica, alumina, surface-silylated alumina, and boron nitride, were tested in this study. Nanocomposites composed of an epoxy/amine resin and one of the five types of nanoparticles were tested as dielectrics with a focus on (i) the surface functionalization of the nanoparticles and (ii...

Modeling of high temperature volumetric solar receivers with supercritical CO2 and nanoparticles

A new method for capturing solar energy is proposed for a Concentrated Solar Power (CSP) plant with supercritical CO2 (s-CO2) as a working fluid. The idea is to disperse a low volume fraction of nanoparticles in s-CO2, that functions as a heat transfer fluid in a volumetric solar receiver and as a working fluid in a power cycle. The advantage of...
