We investigate the electron population dynamics in an ensemble of nearly isolated insulating nanoparticles, each nanoparticle modeled as an electronic two-level system coupled to a single vibrational mode. We find that at short times the ensemble-averaged excited-state population oscillates but has a decaying envelope. At long times, the oscillations become purely sinusoidal about a ‘‘plateau’’...

High density BaZrO3 ceramic crucibles have been successfully fabricated and used to grow high quality YBa2Cu3O7-x single crystals by the BaO-CuO self flux method. The ceramic crucibles are inert and insoluble in the Y2O3-BaO-CuO melt, have a long lifetime, and can be used repeatedly for crystal growth runs. The crystals grown using the crucibles have not only high chemical purity (99.99-99.995%...

Oxide ceramics could be attractive high-temperature construction materials for critical structural parts in molten salt thermal energy storage systems due to their excellent corrosion resistance and good mechanical properties. The 3D-printing technology allows the production of ceramic components with highly complex geometries, therefore extends applications. In this work, 3D-printed ZrO2 Al2O3...
