Phase-pure BiFeO3 produced by reaction flash-sintering of Bi2O3 and Fe2O3
Mixed powders of Bi2O3 and Fe2O3 are shown to yield single-phase, dense nanostructured polycrystals of BiFeO3 in reaction flash sintering experiments, carried out by applying a field of 50 V cm−1 and with the current limit set to 35 mA mm−2. The furnace was heated at...
A direct in situ observation of water-enhanced proton conductivity of Eu-doped ZrO2: Effect on WGS reaction
Eu-doped ZrO2 solid solutions have been synthesized in order to prepare proton conductors as water-enhancer additives for the WGS reaction. Elemental characterization has been carried out revealing homogeneous dopant distribution resulting in fluorite-type solid...
Photonic structuring improves colour purity of rare-earth nanophosphors
Nanophosphor integration in an optical cavity allows unprecedented control over both the chromaticity and the directionality of the emitted light, without modifying the chemical composition of the emitters or compromising their efficiency. Our approach opens a route...
