Green synthesis of some Heterocyclic rings using CoFe2O4 Magnetic Nanoparticles as Efficient and Reusable Catalyst
A robust synthesis for magnetic CoFe2O4 nanoparticles via hydrothermal technique was investigated. The prepared magnetic nanoparticles were characterized by powder x-ray, SEM, TEM, HR-TEM, EDX, TGA, IR analysis and and vibrating sample magnetometry. Based on the obtained data, the prepared powder composed of ultrafine particles in nanometer size range with high homogeneous spherical shape and elemental composition. Moreover, the prepared ...

The Use Of Epr Signals Of Plants As Bioindicative Parameters in The study Of Environmental Pollution
Objective: The change of the signal intensity of the electron paramagnetic resonance (EPR) of plants as privet-Ligustrum japonicum, olive – Olea europea and pyrocantha – Pyracantha coccinea was studied. İn the study of environmental pollution was used EPR signals of plants. Methods: In all study areas the exposure dose rate (EDR) was measured using a MKS- 1125 AT, Atomtex dosimeter ... Read more

Development and functionalization of magnetic nanoparticles as powerful and green catalysts for organic synthesis
Magnetic nanoparticles are a highly worthy reactant for the correlation of homogeneous inorganic and organic containing catalysts. This review deals with the very recent main advances in the development of various nano catalytic systems by the immobilization of homogeneous catalysts onto magnetic nanoparticles. Catalytic fields include the use of mainly cobalt, nickel, copper, and zinc ferrites, as well as their ... Read more
