Abstract:Namen diplomskega dela je bil ugotoviti, kateri način sinteze, bi bil bolj primeren za pripravo magnetnih nanodelcev Cu-Ni z ustrezno sestavo za nadaljno uporabo pri pripravi magnetnih tekočin, uporabljenih v magnetni hipertermiji. Nanodelce smo sintetizirali s pomočjo mletja in mikroemulzij. S pomočjo rezultatov rentgenske praškovne difrakcije (XRD) smo ocenili velikost nanodelcev CuNi in kvalitativno karakterizirali vzorce. S termogravimetrično analizo (TGA) smo pri kontroliranem segrevanju določali Curiejevo temperaturo vzorcev. Morfologijo nanodelcev smo preučevali s transmisijskim elektronskim mikroskopom (TEM). Na koncu so bile izvedene še magnetne meritve z VSM magnetometrom. Optimalna Curijeva temperatura (Tc) 45°C je bila izmerjena pri vzorcu sestave: Cu27,5Ni72,5, ki smo ga pripravili z mletjem. Magnetne meritve so pokazale, da vzorci nimajo koercitivnosti, kar kaže na superparamagnetne lastnosti magnetnih delcev. Morfologija nanodelcev posneta s pomočjo TEM, nam kaže manjše zaglomerirane delce, ki ležijo na večjih ploščicah. Nanodelci vzorca Cu27,5Ni72,5 , ki smo ga sintetizirali z mletjem, bi bili torej najbolj primerni za uporabo v magnetni hipertermiji.

Title:SYNTHESIS OF Cu-Ni NANOPARTICLES FOR THE APPLICATION IN MAGNETIC HYPERTHERMIA
Abstract:The aim of this work was to determine, which way of synthesis is more appropriate for preparation of magnetic nanoparticles CuNi with suitable composition for further preparation of magnetic fluids, which can be used in magnetic hyperthermia. The size of magnetic nanoparticles was estimated by Scherrer equation. Samples were characterized with XRD analysis. Curie temperatures of the samples were mesured with termogravimetric analysis (TGA), during controlled heating. The morphology of nanoparticles was studied with transmission electron microscopy (TEM). Further, the magnetic properties of the samples were measured with VSM magnetometer. The results showed that the optimal Curie temperature (Tc) of 45°C was measured at sample composition: Cu27,5Ni72,5, prepared by milling method. Magnetic measurements indicate that magnetic nanoparticles exhibit superparamagnetic properties. The morphology of nanoparticles showed small agglomerated particles, which are located on large plates. Nanoparticles of sample Cu27,5Ni72,5 synthesized by milling method, would be most suitable for use in magnetic hyperthermia.
Keywords:ball milling method, microemulsion method, Curie temperature, magnetic hyperthermia, magnetic nanoparticles
