Consortium for Advanced Research Based on New Carbon (CARBON-C)

An initiative was taken to establish a major international collaboration in the area of carbon based materials and devices primarily involving US and Indian universities and research institutes. The idea is to actively intervene in the process of emergence and development of carbon as the next generation material that can potentially replace silicon.

Participants were from different Indian institutes (IITs, CSIR labs, NIFFT, SINP, and IIEST) including Prof. AmitabhaGhosh, Senior Scientist, INSA and former Director, IIT, Kharagpur, Professor Prof. Ajoy Kumar Ray, Director, IIEST, Shibpur and Prof. Marc Madou, University of California, Irvine among others.

Technology Transfer for Commercialization

Subject specific customization of Hip Implant

Primary purpose of the research is to develop patient specific hip implant. It should be fully customized and particularly compatible to Indian subjects

4

Implants are designed and fabricated through various advanced machining processes. These implants are subject-specific as per the specific anatomical geometry and physiological pre-surgical condition of the bone (femur).

Radio Controlled Blimp

Radio Controlled Blimp is an aerial vehicle, a type of an airship without internal structure in which case the balloon envelope, when filled with lighter-than-air gas (such as helium or hydrogen) lifts the complete system in air. A control box called the gondola carrying drives and wireless electronic controller fitted underneath the envelope controls the movement of the complete system in air.

7

RC blimp had been tested and demonstrated in the campus of IIEST Shibpur in the month of May 2012. It can be used for local weather forecast, aerial forest security, remote aerial surveillance, disaster management, brand promotion, film shooting etc. Blimp of size 35ft, 40ft and 45ft length are being planned for larger payload capability with high endurance capability with customized specifications.

Underwater Lift Bag

A lift bag is an item of diving equipment consisting of a robust and air-tight bag with straps, which is used to life heavy objects underwater by means of the bag's buoyancy. The heavy object can be moved horizontally underwater by the diver or sent unaccompanied to the surface.

300 kg load was recovered from the pond near the IIEST campus as shown in the figure above. The load had slipped from the edge and plunged into the water, which was difficult to recover by the swimmers alone. A closed bottom lift bag which itself weight 12Kg was used, which just took maximum of 20mins to recover.

In the MCEME Hyderabad campus, a demonstration was carried out to understand the feasibility of the lift bag for the Indian armed forces. Military truck axels were put inside the fire fighting well, which were then floated and recovered by 2 quantities of 3 Ton closed bottom lift bags. The lift bags had weight of around 26kg.

Rear Projection Balloon

Projection balloons are image display balloon device made of light weight plastic fabric material, is inflated with air or helium gas, where it has at least one projector positioned with a projector case inside. The main change is the balloon shape which is being called the pearl shape designed by the team which has bit of cylindrical shape from the exact spherical shape due to which effects of the joints of the fabric is eliminated from the surface of the projection.

The projection balloon was used and demonstrated for the closing ceremony of the prestigious Kolkata International Film Festival 2013. It was used to display the gist of the activities conducted during the festival days to the visitors in the Science City Auditorium, Kolkata
