combined effect of $gamma$ -irradiation and organic solvents on some structural properties of cotton fibers

the combined effects of $gamma$ -irradiation and organic solvents on some structural properties of cotton fibers were investigated by following the changes in their x-ray diffraction and infrared spectra. $gamma$ -irradiation of cotton fibres in air results in the oxidation of the cotton cellulose and the formation of carbonyl groups, whi..

gel permeation chromatography of the thermal degradation of cellulose insulation paper in an aged power transformer

the lifetime of a power transformer and its capacity to be refurbished is often determined by the condition of the cellulose insulation materials used to wrap the copper windings. as a transformer ages the molecular weight of the cellulose in the insulation paper decreases. here we describe a study of the accelerated ageing of cellulose i..

hch and carbaryl residues in groundnut

groundnut plants were treated with hexachlorocyclohexane (hch) or 1-naphthyl-n-methylcarbamate (carbaryl) following agricultural practices and the residues were followed in seed and oil. in the oil extracted from kernels of hch treated plants, beta -isomer of hch was present in greater amounts than other isomers. commercial procedures lik..
