Fully crystalline single phase multi-component fluorite oxide (Gd0.2La0.2Y0.2Hf0.2Zr0.2O2 and Gd0.2La0.2Ce0.2Hf0.2Zr0.2O2) nanoparticle sols were synthesized at low temperature (≤80 °C) by co-precipitation followed by peptization in acidic medium.

Mn3o4 Nanoparticles

AbstractHeating hydrous manganese (II) hydroxide gel at 85 °C for 12 hours produces Mn3O4 nanoparticles. They were characterized by X-ray powder diffraction (XRD) and infrared spectroscopy (FTIR). The particle size estimated from the SEM and X-ray peak broadening is approximately 32 nm, showing them to be nanocrystalline. EPR measurements confirm a typical Mn2+signal with a highly resolved hyperfine structure.
