    Abstract: The interaction between glucosamine molecules has been studied theoretically. The geometrical structures of monomer (A), dimer (AA) and trimer (AAA) molecules of glucosamine were optimized and vibrational spectra were calculated by DFT/B3LYP method using GAMESS software (Firefly version 8.0.0). The theoretical vibrational spectra for the glucosamin... Show More

    Abstract: An attempt has been made in the present work to develop blend based mixed ion-electron conductor viz. PVA: PVK: CH3COONH4: EC system. Formation of polymer blend and composite has been evidenced during XRD and IR studies. Ionic conductivity of this system is seen to improve by an order of magnitude at room temperature with optimum at 1.27×10-3 S/cm ... Show More
