Tannery waste water treatment using membrane bioreactor
Tannery effluent was collected from a leather processing unit located at Bantala leather complex, Kolkata and characterized in detail. The effluent showed typical value of COD 6500 mg/L, BOD5 1000 mg/L and Cr+6 content of 70 mg/L. Batch mode bioreactor studies were...
Ce3+:Y3Al5O12 (YAG) Phosphor-in-Glass (PiG) for High Color Rendering White LEDs
The market potential of White-Light-Emitting Diodes (WLEDs) for efficient and environment-friendly lighting is on upswing. The use of high-power Light-Emitting Diodes (LEDs) for even higher efficiencies plays a crucial role in applications of indicator, backlight,...
Improved thermal stability and antibacterial properties of bioactive glasses: effect of B2O3 incorporation
Bioactive glasses are widely used for bone repair and regenerative applications due to their ability to form hydroxyapatite bone mineral on the surface and their ability to naturally bond with bone. Commercial glasses such as 45S5, S53P4 and 13-93 belonging to...
Mesoporous SiO2– based Anti-Reflective (AR) coating on solar cell cover glasses
Nanostructured mesoporous silica based hard and AR coating with hydrophobic surfaces on millimeter scale textured solar cover glasses showing better light conversion efficiency and stability have been developed. Solar panel has been fabricated using fabricated solar...
