The spent biosorbent generated after multi-metal (Ni(II), Co(II), Zn(II) and Cd(II)) biosorption using dried activated waste tannery sludge were applied for glyphosate removal. The removal efficiency could be enhanced from 26.18 % to >92% after increase in the...

Magnesia is the most important refractory raw materials used mainly in the steel and cement industries. Indian magnesite (mostly of Salem and Almora origin) is a less-preferred variant amidst the harsh steelmaking conditions (tapping temperature > 1700oC and slag...

10 Gamma alumina-based trace moisture sensors (2-50ppm) have been fabricated. These sensors were mounted on threaded Teflon holders which can be fitted into transformer oil filtration units for detection of trace moisture present in transformer oil. For laboratory...

A ‘ready-to-use’ Pulsed Yb-Fiber laser module has been developed. M/s Spinks Impex, Gurugram, completed thorough performance evaluation of 20W pulsed fiber laser module by synchronizing their existing marking system with the indigenously developed electronic...

A semi-automated apparatus has been designed and fabricated by CSIR-CGCRI which is capable of producing the developed paper-based separator in large volume in the form of rolls of 50-100 meters long of varied width for fabrication of Li-ion batteries(for example 18650...

Distributed feedback fiber laser (DFB-FL) is a kind of laser consisting of a single phase shifted fiber grating directly writing in the rare earth doped fiber, depending on the narrow bandwidth, low noise, and stable single-mode operation. In this project, CGCRI...

RSW glass melting in indigenously developed 10L coarse body refractory crucible with fine body layer by tilt casting method using 10L scale Raising Hearth furnace, has been successful. This is currently being scaled up to a 60L scale using in-house fabricated 60L...

Alumina-based refractories are ubiquitous in several high temperature structural applications and the use of synthetic and purer raw materials for manufacturing of refractory products is a prerequisite for clean steel production. As a part of the work under this...

As a part of an initiative under LSRB of the DRDO, nano-graphite incorporated polyurethane based nanocomposite has been developed upto 2 kg batch level for making light weight, anticorrosive and flexible shoe-outsoles for the use of military personnel working...

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...
