• /bjnano.9.166 Abstract In the present investigation, the cryochemical approach was used for the improved synthesis of nanocrystalline metal oxides (e.g., NiO, Fe2O3, CeO2) and NaNO3 salt. It was shown that the solutions and sols can be treated with a liquid nitrogen stream (−196 °C) to increase the powder
