Role of Raman Spectrometry in Understanding Structure, Function, and Position of Lipids in a Cell
Abstract: Recent researches focus on the functional aspects of lipids as they equally perform with proteins and enzymes in metabolisms and other biological processes. Lipids are fatty substances soluble only in alcohol and ethers but insoluble in water or other polar solvents. The Raman Spectrometry is a proven technique used for the proper understanding of the structure, function and position of lipids in a cell. The lipid study can be done …

ESR Evidence of Growing Unsaturation in -Irradiated Poly (Vinyl Alcohol)
Abstract: AbstractFree radicals present in gamma irradiated PVAL subjected to different degrees oxidation are identified using ESR spectroscopy. The observed ESR spectra are analysed by computer simulations. Gamma irradiated PVAL immediately after irradiation possess ~CH2–CH–CH2~ type free radicals (I). Upon oxidation the free radicals transform to ~CH2–CH=CH–CH2~ (II) highly oxidized PVAL consist ~CH2–C=O (III) type free radicals. The results suggest that radical (I) is precursor to radicals (II) and (III). Oxidation …

Determination of Fatty Acid Composition of Roasted African Palm Weevil Larvae (Rhycophorous phoenicis)
Abstract: AbstractThe study was demonstrated to evaluate the fatty acid composition of roasted African palm weevil larvae, and the degree of saturation. The result obtained shows that unsaturated fatty acid is dominant with the value of mono to polyunsaturated fatty acid rage between 20.17 and 58.37% respectively. However, the total saturated fatty acid evaluated was 20.83%. The study concludes that roasted African palm weevil larvae is a potential source of unsaturated …

Dielectric Behaviour of Nanosilver and Silver-CNT Hybrid Reinforced Nanocomposites
Abstract: The present study concerns study of the dielectric properties of Ag-CNT vis-à-vis Ag reinforced unsaturated polyester matrix composites. The Ag-CNT hybrid was prepared by mechanical milling. Variation of the dielectric properties has been attributed to the morphological features and the degree of dispersion of the fillers. It has been found that dispersion of Ag-CNT hybrid particle is beneficial for improvement of the dielectric properties.

Electron beam irradiation studies of polyethylene maleic anhydride on their Chemical and Thermal properties.
Abstract: The electron beam (e-beam) irradiation effects on polyethylene maleic anhydride (MANPE) are investigated by spectroscopic and thermal methods. The MANPE irradiated with electron beam to a radiation dose of 30, 60 and 90 K Gy and the resultant changes in their chemical structure and thermal properties have been investigated by Electron spin resonance (ESR), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), X-ray diffraction (XRD) and scanning electron microscopy …
