Materials synthesis: synthesis of nanoparticles: coprecipitation of Fe(II) and Fe(III) ions in alkaline medium, YIG (yttrium-iron oxide garnet) self-combustion of ruby jelly, Stöeber method, hydrothermal ageing, etc. Equipments for preparation: water purification system, mixers, heating baskets, thermal baths, supercentrifuge (Sorwall), driers, ovens, furnaces (up to 1300oC), freeze-drier, high energy ultrasonication and colloidal mill (vibrating agate mill), pH-meter, conductivity meter.

Synthesis of nanoparticles: effect of experimental conditions - as an example: crystal structure, size, morphology and magnetic properties of superparamagnetic (~10 nm) or ferrimagnetic (~75 nm) magnetite nanoparticles prepared by the modified coprecipitation or oxidation-precipitation method.
