Abstract:
Solid Polymer electrolytes (SPEs) comprising of poly(vinyl alcohol) (PVA)added Zinc chloride (ZnCl2) systems have been prepared via solvent castingtechnique. The prepared samples have been subjected to AC impedancespectroscopic analysis and Fourier Transform Infrared Spectroscopy (FTIR)studies. Maximum ionic conductivity of 3.91949*10-7 Scm-1 was achievedfor 60 wt% of PVA and 40wt% of ZnCl2 system at room temperature.The...

Abstract: Power transmission by the belts is defined as, the transmission of power by a moving pulley to one or more driven machines through a flexible non-metallic member. There are different types of V-belts available, and Transmission Belts are one of them. Transmission V-Belt is the first invented non-metallic belts. Nowadays V-belts are used in various... More

Abstract:
The effect of proportional blend of periwinkle and African star apple seed shell as bio-fillers in flexible polyether foam was studied. Flexible polyether foam samples incorporated with these bio-fillers at varying percentages; 10% (S1), 20% (S2), 30% (S3), 40% (S4) and 50% (S5) were produced respectively, while 0% (S0) which had no filler was used...

Abstract: Molecular spectroscopy (electronic, FT-IR, NMR), methods of thermal and elemental analysis were used for the first time to describe the process of thermo-oxidative oligomerization of 1,3-bis-(4-aminophenoxy)benzene. Introduction of this monomer into linear and network copolymers makes it possible to improve processability, mechanical strength and heat resistance of materials. The structures of copolymers obtained by thermo-oxidation... More
