Title of Talk: Comparative study on the heating efficiency of CTAB coated superparamagnetic MnFe2O4, NiFe2O4 and ZnFe2O4 nanoparticles for Hyperthermia application
CTAB (cetyltrimethylammonium bromide) coated manganese ferrite (MnFe2O4), nickel ferrite (NiFe2O4) and zinc ferrite (ZnFe2O4) nanoparticles with crystallite sizes of 23 nm, 15 nm, and 28 nm respectively were successfully synthesized by a facile co-precipitation method. The presence of CTAB on the surface of the nanoparticles was confirmed by the Transmission Electron Microscope (TEM) and Fourier Transform-Infrared spectrum (FT-IR). The magnetic study shows a high saturation magnetization of 46 emu/g (MnFe2O4), 59 emu/g (NiFe2O4) and 55 emu/g (ZnFe2O4) which indicates the Fe-O-Fe super-exchange interaction driven by the synergistic influence of magnetocrystalline anisotropy and cation distribution. The Field Cooling (FC) and Zero Field Cooling (ZFC) curves confirmed the superparamagnetic nature of all the samples. The induction heating study elucidates the efficiency of heat generation (>42°C) in all samples showing an exceptionally high specific absorption rate (SAR) of 480 Wg-1, 684 Wg-1, 586 Wg-1 at 2 mg/ml in which CTAB-NiFe2O4 nanoparticles shows the highest efficiency. This is attributed to the co-dependent factors: size, saturation magnetization and Neelian relaxation loss mechanism. This comparative study discussed on the collaborative influences of structural motifs and magnetic properties that engendered the effectiveness of heat generation making it viable for hyperthermia application.

Lasienthra africanum (LA) leaf extract was employed for nano-silver synthesis. The reducing effect of the plant extract was investigated at different times, pH, temperatures and concentrations. The effect of various kinetic parameters was studied using UV–vis spectroscopy. Blue-shifted surface plasmon bands indicating smaller sized nanoparticles were obtained at neutral pH (6.8–7.0), temperature of 65◦C and concentration ratio of 1:10 (leaf extract: AgNO3) with increasing reaction times under the reaction conditions. The kinetics of the reaction followed pseudo-first- and -second-order rate equations, and was thermodynamically favoured at higher time. Spherically shaped nanoparticles were obtained at different reaction conditions.
