Eta phaseNanoparticlesCytotoxicityCrystalline structureThe role of the crystalline structure on the toxicity of two phases of Al2O3 NPs, alpha (alpha-Al2O3 NPs) and eta (eta-Al2O3 NPs), was investigated in this study. Different techniques were employed for the characterization of the Al2O3...
The natural occurrence of eta-alumina (eta -Al 2 O 3 ) in bauxite Approximately 20 wt.% of the bauxite from Andoom in northern Queensland, Australia is composed of material that cannot be accounted for by identifiable well-crystallized phases. This poorly-diffracting material (PDM), found ...
