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 ...

Nowadays graphene based composites were developed due to their unique structure and excellent properties. Present study involves the preparation of graphene grafted chitosan and hydroxyapatite (GgCH) composite through solution casting method for biomedical applications. The prepared composite was characterised by FTIR, TGA, DSC XRD and SEM analysis. The formation of GgCH composite was confirmed...

Nanoparticles of iron-cobalt have attracted great interest in recent years because of their unique physical and chemical properties because of their industrial importance in preparing magnetic recording materials, pigments, catalysts, etc. With an objective to develop magnetic materials with high saturation magnetization Fe-Co nanosysytems were synthesized by method of chemical reduction reacti...

techniques such as SEM, TGA, XRD, friction and wear tests are used to characterize the formulations as well as the commercial material. Out of the 30 formulations made, two formulations viz., S1 and S2 closer to commercial material are presented in this work. Formulation S2 exhibits better thermal stability and better wear resistance. With the help of SEM analysis, physical properties and XRD s...

This article introduced the work of ethylcellulose based polymeric microsphere loaded with nifedipine for reduction in frequency of administration with low solubility in aqueous medium and high rate of absorption in the stomach. The non-aqueous polymeric suspension was put dropwise into an aqueous medium containing polyvinyl alcohol as a surfactant for the synthesis of microsphere by solvent ev...

Inspired green synthesis of metallic nanoparticles is evolving as an important branch of nanotechnology. Traditionally these are manufactured by wet chemical methods which require toxic and flammable chemicals. We report for the first time an economic and eco-friendly green synthesis of silver nanoparticles using Strychnos potatorum aqueous leaf extract from 3 mM silver nitrate solution. Nanopa...
