Effect of Europium Substitution on the Structural and Magnetic Properties of Nanocrystalline Cobalt Ferrite
A series of Europium-substituted cobalt ferrites (CoEuxFe2-xO4 with = 0.00, 0.10, 0.20, 0.30) were synthesized by hydrothermal method. The structural characterizations of all the prepared samples were done using XRD and FTIR. These studies confirmed the formation of single-phase spinel structure in all the compositions. The increase in the value of lattice parameter with increase in Europium concentration suggests the ... إقراء المزيد

Pharmaceutical Applications of Nano Imine Complexes and Their Oxides
Some new nano-sized Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Cd(II), Zn(II),, Pb(II) and Ag(I) complexes with imine ligands derived from 2-amino-3-hydroxypyridine (ahp) and 3-methoxysalicylaldehyde (v) or 4-nitrobenzaldehyde (nb) were prepared by sonochemical method. Melting point, decomposition temperature, infrared (IR) and NMR spectra, elemental analyses, conductance and magnetic susceptibility measurements, TG and UV – Visible spectrophotometric studies were utilized in characterizing of ... إقراء المزيد
