Bio-intercalation based Polyaniline (PANI)-Aloe vera (AV) with Lithium Perchlorate (LiClO4) composites has been synthesized by In-situ chemical reaction method. The composite was employed characterizations with help of Fourier Transform Infrared (FT-IR) Spectroscopy and Scanning Electron Microscopy (SEM) to know the chemical interaction and morphology of the composites. From SEM result it was noticed that morphology became changes significantly with reduce porosity. The Ultra Violet Absorption (UV-Vis) study shows that absorption increases as well as maximum peak shifts and PAL10 red shifts in visible region at 615nm. These results manifest that PANI-AV/LiClO4 (PAL) composites are the promising materials for solar cell, LED’s and electrical applications. Copyright © 2017 VBRI Press

Ni-Cu-Zn ferrites with compositional formula Ni0.8-xCuxZn0.2Fe2O4, where 0.0≤x≤0.5 in steps of 0.1 were synthesized by the citrate precursor method. The samples were subjected to final sintering at 900ᵒC for 2h after a pre-sintering at 600ᵒC for 4h. X-ray diffraction patterns confirmed the formation of single phase spinel structure. The average crystallite size was calculated using Scherrer’s formula and was found to vary from 33nm to 39nm, clearly indicating the formation of nanoparticles. The infrared spectra were recorded at room temperature for all the samples in the range of 450 cm‾1 to 4000 cm‾1 using Perkin Elmer FT-IR Spectrometer. Jahn-Teller effect emerges which can be identified through the FT-IR Spectroscopy of the samples. This phenomenon may result in useful electro and magneto- optical applications. Possible mechanism is being discussed. Copyright © 2017 VBRI Press.
