Abstract:V tem diplomskem delu smo se ukvarjali s problematiko sinteze nanodelcev, specifično s sintezo nanodelcev z ustrezno Curiejevo temperaturo (TC), ki je v idealnem primeru v območju terapevtske temperature, 41 °C – 46 °C. Za sintezo smo uporabili mikroemulzijsko tehniko, s sestavo 60:30:10 (izooktan : (CTAB+1-butanol) : vodna faza raztopljenih magnezijevih, železovih in titanovih soli) v ternarnem diagramu. Za obarjanje hidroksidov smo uporabili raztopino amoniaka. Naš cilj je bil sintetizirati nanodelce s sestavo Mg1+xFe2-2xTixO4, pri čemer smo izbrali x = 0.37. Po sintezi smo nanodelce čistili z etanolom in nato z vodo v ultrazvočni kopeli. Po posedanju delcev v centrifugi je sledila kalcinacija na zraku pri izbrani temperaturi. Sintetizirane delce smo analizirali s termoanalitskim sistemom TGA/SDTA v območju od 25 °C do 1000 °C ter jim na modificirani aparaturi določili tudi TC. Sledila je nadaljnja analiza z rentgensko praškovno difraktometrijo (RTG).

Title:Synthesis of Mg1+xFe2-2xTixO4 nanoparticles using reverse microemulsion method
Abstract:In this diploma work, we addressed the problematics of nanoparticle synthesis, specifically synthesis of nanoparticles with a lower Curie temperature (TC), that would be, in an idealized case, somewhere in the narrow therapeutic temperature range, 41 °C – 46 °C. Reverse microemulsion method was used, with a composition ratio of 60:30:10 (isooctane : (CTAB+1-butanol) : aqueous phase of dissolved magnesium, iron and titanium salts) in the ternary phase diagram. Ammonia solution was used for the precipitation of hidroxides. The goal was to synthesize nanoparticles, with a composition of Mg1+xFe2-2xTixO4, where x= 0.37. After the synthesis, the nanoparticles were cleaned using ethanol and water in the ultrasonic bath. Finally, after centrifugation the samples were calcined in air at various temperatures. For the characterisation of synthesized nanoparticles, we used thermoanalytical system TGA/SDTA, with temperatures up to 1000 °C. With small modifications, the same equipment was used for determining TC. For further analysis, we used X-Ray powder diffraction (XRD).
