Abstract

In this study, we analyzed the magneto-heating properties of NiFe2O4 nanoparticles, coated with a SiO shell for hyperthermia applications. The NiFe2O nanoparticles were synthesized and coated with SiO2 by chemical route and water in oil techniques, respectively. The size of core particles is ~5.6±0.1 nm and the thicknesses of the SiO2 layers around the core change from 0 nm to 14.1±0.1 nm by increasing the amount of tetraethyl orthosilicate from 0 ml to 2.5 mL during the synthesis process. The magnetic anisotropies, obtained from magnetic susceptibility measurements have the same behavior with the specific heat absorption ratio of the samples

Özet

Bu çalışmada, hipertermi uygulamaları için SiO2 ile kaplanmış NiFe2O4 nanoparçacıklarının magnetikısıtma özellikleri analiz edildi. NiFe2O4 nanoparçacıkları kimyasal yöntemle sentezlenerek, mikroemülsiyon tekniğiyle SiO2 ile kaplandı. Çekirdek parçacıklarının boyutu 5.6 ± 0.1 nm'dir. Kaplama sürecinde çekirdek çevresindeki SiO2 tabakasının kalınlıkları tetraetil ortosilikat miktarı 0 mL'den 2.5 mL'ye arttırılarak 0 nm'den 14.1 ± 0.1 nm'ye kadar değiştirilmiştir. Manyetik duyarlılık ölçümlerinden elde edilen manyetik anizotropi değerleri, spesifik ısı emme katsayıları ile benzer davranışlar göstermiştir
