    Abstract: For centuries the area which is now Bangladesh was known throughout the civilized world for its fabled wealth, of which the exquisite muslin, Sundarbans, Cox’s Bazar un-broken sea beaches were the apt symbol. Aryans, Turks, Mughals, Afghans, Arabs, Dutch, Portuguese, French and British were attracted by the opulence of Bengal. They came as invaders... Show More

    Abstract: We synthesized four different rhenium complexes, Re(bpy-R)(CO)3Cl (bpy = 2,2-bipyridine and R = H, CH3, COOH, or CN), as photocatalysts that selectively reduce CO2 to CO and investigated the effect of substituent groups (Rs) on the absorption and photocatalystic properties for CO2 reduction under 365-nm light irradiation. The Re(bpy-R)(CO)3Cl (R =... Show More

    Abstract: This research employed the technique of melt blending to successfully blend commercial polystyrene (PS) with purified cashew gum (PCG) and induce biodegradation on the resulting polymer blend. Water sorption tests on the resulting polymer blends were investigated according to ASTM D0570 standard. Also tensile, hardness and charpy impact tests were ... Show More
