:  A fast breeder reactor (FBR) breeds more fuel than it consumes that is it produces more plutonium than it consumes while generating power. For a uranium scarce country like India, it is an attractive technology. Plutonium produced in the thermal reactors as spent fuel is ideally suitable as the fuel material for use in … Read more

The Mission envisages empowering national academic and R&D institutions spread over the country by installing a vast supercomputing grid comprising of more than 70 high-performance computing facilities.  These supercomputers will also be networked on the National Supercomputing grid over the National Knowledge Network (NKN). The NKN is another programme of the government which connects academic … Read more

When rubbers bands are twisted and untwisted, it produces a cooling effect. This is called the “elastocaloric” effect, and researchers have suggested that it can be used in a very relevant context today. The elastocaloric effect, if harnessed, may be able to do away with the need of fluid refrigerants used in fridges and air-conditioners. … Read more

Cloud seeding is the process of spreading either dry ice, or more commonly, silver iodide aerosols, into the upper part of clouds to try to stimulate the precipitation process and form rain. There are three cloud seeding methods– Hygroscopic cloud seeding disperses salts through flares or explosives in the lower portions of clouds. The salts grow in size as … Read more

Fiber optics, or optical fibers, are long, thin strands of carefully drawn glass about the diameter of a human hair. These strands are arranged in bundles called optical cables. We rely on them to transmit light signals over long distances. At the transmitting source, the light signals are encoded with data… the same data you see … Read more

The nitrogen cycle is a complex biogeochemical cycle in which nitrogen is converted from its inert atmospheric molecular form (N2) into a form that is useful in biological processes. The Nitrogen cycle contains various stages: Nitrogen fixation: Inert form of Nitrogen is fixed and converted into organic form in a process called nitrogen fixation. Most … Read more
