  An Investigation on Influence of Gamma Irradiation and Doping on Chemical Structure and Optical Properties of Conducting Polypyrrole

  By N Venkateswara Rao, B Sanjeeva rao, A Raju

  Abstract: In this study the authors report on effect of gamma irradiation and doping (bromine, iodine and sulfate ion) on chemical structure and optical, electronic properties of poly pyrrole. Optical absorption spectrum of PPY shown absorption bands centered around 36.2.5nm (peak 1), 450 nm (peak2) and 525 nm (peak 3) positions Gamma irradiation resulted in broaden of peak A together with a band shift of 45- 525 nm and disappearance peaks …

  Effect of Gamma and Electron Beam Irradiations on Crystalline and Gelatinization Properties of Edible Potato Starch

  By N. Venkateswara Rao, Amireddy Raju, N. Rajeswara Rao, B. Sanjeeva Rao

  Abstract: Exposure of food material to radiation causes changes in crystalline (damage of crystal structure / lattice distortion), and gelatinization (digestive)properties. Potato starch (PS) is one of the important globally used food supplement in different forms like chips, curries, cusins etc. During its use the PS is exposed to radiations, altering its molecular structure (due to chain cleavages) and bring changes in structural and physical properties ; sometimes ill – effects …
