A controllable transformation in copper valence states and its applications.
The present study revealed a surprising valence transformation of copper (Cu) in the sintering process of mixtures of copper chloride dihydrate (CuCl(2)·2H(2)O) with β-cyclodextrin (β-CD) in ambient atmosphere. Such a transformation in Cu valence states can be modulated by changing the initial molar ratio (IMR) of CuCl(2)·2H(2)O to β-CD in the mixtures. Firstly, as the value of IMR decreased, t...
متن کاملSynthesis and characterization of Nickel Copper Ferrite
Nano size nickel copper ferrite powders (NiCuFe2O4) have been prepared by a prepared by Co precipitation method. The resulting powders were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM).The result showed nanosize nickel copper ferrite(35.65nm). The powders showed extensive XRD line broadening and sizes of crystals observed from the XRD line broadening was35.65 nm,...
متن کاملAb initio study on copper ferrite
The impact of cation distribution on electronic structure and magnetic properties is investigated by the first-principle calculation. The structure optimization is based on generalized gradient approximation GGA exchange-correlation and projector augmented wave method. The optimized structures of inverse and normal copper ferrite are tetragonal c /a=1.06 and cubic, respectively. The optimized s...
