Synthesis of protoporphyrin coated superparamagnetic iron oxide nanoparticles via dopamine anchor
Abstract Dopamine conjugated protoporphyrin, PPD, was prepared by the coupling reaction of protoporphyrin IX and dopamine in the presence of dicyclohexylcarbodiimide (DCC) and N-hydroxysuccinimideExpand
Surface spin disorder and spin-glass-like behaviour in manganese-substituted cobalt ferrite nanoparticles
Manganese-substituted cobalt ferrite nanoparticles coated with triethylene glycol (TREG) have been prepared by the glycothermal reaction. The effect of Mn substitution and coating onExpand
CTAB-Mn3O4 nanocomposites: Synthesis, NMR and low temperature EPR studies
Abstract We are reporting on the synthesis of Mn3O4 nanoparticles and CTAB-Mn3O4 nanocomposites via a sonochemical route using MnCl2, ethanol, NaOH and CTAB. The crystalline phase was identified asExpand
Magnetic properties of Co3O4 polycrystal powder
Abstract The results of investigations of magnetic properties of Co 3 O 4 polycrystals in powder morphology with average crystallite size of 10 µm are presented. The temperature dependence of theExpand
Electron paramagnetic resonance studies of Cu2+ ion in tetraaqua-di(nicotinamide)Ni(II)-saccharinates single crystals.
X-band (approximately 9.8 GHz) electron paramagnetic resonance (EPR) measurement at ambient temperature in three mutually perpendicular planes have been carried out on a single crystal of Cu2+ doped mixed ligand complex of Ni(II) with saccharin and nicotinamide to show the nature of the distortion present in the lattice.

Magnetic and dielectric characterization of alginic acid-Fe3O4 nanocomposite
We have reported the synthesis of water dispersible alginic acid (AA)-Fe3O4 nanocomposites. The crystallite size was obtained as 9 +/- 2 nm from X-ray line profile fitting. As compared to the partiExpand
Size effects and origin of easy-axis in nickel nanowire arrays
High quality compact Ni nanowire (NW) arrays with aspect ratios (wire length/diameter) varying between 70–171 for a wire length of ∼6 μm, and between 3–400 for a constant wire diameter of 60 nm wereExpand
Synthesis and characterization of CuFe2O4 nanorods synthesized by polyol route
Uniform, high quality, CuFe2O4 nanorods with high aspect ratios were synthesized by a surfactant-free single step polyol process at 220 degrees C. The structure of the product was characterized by ...
Synthesis, characterization and magnetic properties of Fe3O4 doped chitosan polymer
Abstract Fe 3 O 4 nanoparticles doped into chitosan films were prepared by the solution casting technique. Various samples were synthesized in atmospheric medium and in vacuum. The morphologicalExpand
EPR studies on Cu2+ and Co2+ complexes of tetraaza porphyrin derivatives
Abstract The electron paramagnetic resonance (EPR) investigations on 2,9,17,23-tetra-((1,1,2-(tricarbethoxyethyl)) phthalocyanine,Expand
