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,...

Calcium pyrophosphate (CPP) was prepared by a simple precipitation method using avian eggshell waste as a low-cost alternative calcium precursor source. The synthesized CPP powder was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM/EDS), thermogravimetric analysis (TGA), and Fourier transform infrared spectroscopy (FTIR). The results indicate that pure b-CPP nanocrys...

Peroxidase has been immobilized onto the PVA-PANI nanocomposite film deposited onto gold plate via physical adsorption for peroxide detection. PVA-PANI nanocomposite was characterized by scanning electron micrograph (SEM) before and after immobilization. The SEM picture clearly shows the immobilization of peroxidase onto the PVA-PANI. The cyclic voltametric study is also carried out for the as ...
