AB  - Light-transmitting measurements of white light and a consequentially chosen laser beam of 655 nm propagating
through citrate- and oleate-coated CoFe2O4, FeFe2O4, and MgFe2O4 nanoparticles under the influence of an
external magnetic field were presented. New experimental settings were developed for the optical study of
ferrites’ behavior in ferrofluid with the applied magnetic field strength within the 30–400 mT range. A magnetic
field-induced change of light transmittance occurred and a precipitation of all studied samples was obtained.
Optical investigations of ferrofluid suspensions revealed that, contrary to the linear aggregates of colloidal
CoFe2O4 and FeFe2O4, spheroidal aggregates were formed in the case of MgFe2O4. In all three cases, the surface
modification resulted in decreased dipole–dipole interactions between ferrite cores, and thus, less precipitates
were noticed. All oleate-coated nanoparticles have demonstrated weaker magnetic responses compared to the
citrate-encapsulated samples. The aggregation of nanoparticles potentially increases cytotoxicity. Regarding
non-linear clustering of MgFe2O4 suspensions, it can be concluded that its excretion from the organism may
likely be easier and faster when used in diagnosis and/or therapy. Therefore, more attention should be paid to
the lowly toxic MgFe2O4 regarding its medical application.

AB  - Kinetic modeling and optimization of sunflower oil methanolysis catalyzed by spherically-shaped CaO/gamma-Al2O3 particles were conducted in batch stirred and packed-bed tubular reactors at 60 degrees C. The proposed three-parameter kinetic model describing the overall reaction with a variable mechanism was successfully applied to both batch and continuous reactions. The process optimization was done using the response surface methodology combined with a central composite design. The obtained optimal catalyst concentration, methanol-to-oil molar ratio and reaction time for the batch reaction were 0.55% (CaO to the oil), 9:1 and 5.22 h, respectively. In the continuous process, the catalyst was highly active stable and slightly leachable during 30 h. The deactivation of the catalyst was due to massive deposition of the organic molecules from the reaction mixture, which sheltered the catalytically active sites on the catalyst surface.

AB  - Cobalt ferrite (CoFe2O4) particles have been prepared in nanocrystalline form by several techniques (hydrothermal synthesis, ultrasonic assisted synthesis, microemulsion synthesis, mechanochemical synthesis and microwave synthesis). All samples were coated with starch to find biomedical applications in the field of drug delivery, MRI and hyperthermia. Cobalt ferrite is chosen because its high magneto-crystalline anisotropy that originates from the spin-orbit coupling at crystal lattices. The synthesized coated and uncoated nanoparticles were characterized by X-ray powder diffraction (XRPD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Light transmitting measurements of laser beam of 655 nm propagating through starch coated CoFe2O4 nanoparticles, under the influence of an external magnetic field, were presented.
