Centre for Advanced Materials Research

 

Advanced material technologies have already conjured up speculation about a seismic shift in almost every aspect of science and engineering. They have already insinuated into our lifestyles through innovations leading to develop methodologies to generate cleaner energy, purify water, smart materials, new drug delivery systems, faster and cheaper manufacturing processes as well as the next generation computing devices. For example out of the many such developments nanotechnology promises more for less: smaller, cheaper, lighter and faster devices with greater functionality, using less material and consuming less energy. As a result today there is an increased research focus in development of new materials through multi-disciplinary. Fundamental and applied researches on such applications are major part of the innovations, where global research focus has been recently on. In order to move in par with the global paradigm shifts in science and technology focus centre for Advanced Materials Research was established in 2015. The centre focuses on advanced technologies in order to uniquely value add to our science and technology output as well as enabling our graduates to be equally competent and competitive with the other graduates emerging from world class universities and research backgrounds. Furthermore, it is expected to create a continuous pool of talents required for moving towards an “innovation driven knowledge based economy model for a smarter nation”.

Vision
