24th March, 2017, USTM, Meghalaya : University of Science & Technology Meghalaya & ECE Department, Regional Institute of Science & Technology had organized a Talk on “Nano Technology and its Multidisciplinary Applications” by Prof. Sunandan Baruah, Prof. & Head, Department of Electronics & Communication, Assam Donbosco University. He was warmly welcomed and felicitated by Dr. R K Sharma, Pro VC, USTM & Prof. Enamul Karim, Dean, School of Applied Sciences, USTM. Dr. Sharma in his welcome address had touched the different uses of nano technology for the sake availing economy, agricultural and medical advancement and progress.
24th During the last twenty years, scientists have been looking towards nanotechnology for the answer to problems in medicine, computer science, ecology and even sports. In particular, new and better techniques for pollution control are emerging as nanoparticles push the limits and capabilities of technology. Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. The ideas and concepts behind nanoscience and nanotechnology started with a talk entitled “There’s Plenty of Room at the Bottom” by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology (CalTech) on December 29, 1959, long before the term nanotechnology was used. In his talk, Feynman described a process in which scientists would be able to manipulate and control individual atoms and molecules. Over a decade later, in his explorations of ultra precision machining, Professor Norio Taniguchi coined the term nanotechnology. It wasn’t until 1981, with the development of the scanning tunneling microscope that could “see” individual atoms, that modern nanotechnology began.
Prof. Sunandan started his lecture having stressed on the fact “today we are able to manipulate and control matters in Nature just because nano technology is available with us”. In this connection he had cited examples of sophisticated mobile transistors “tri-aided transistors” that are being used by INTEL which is just 14nanometers in size and the invention of this technique is possible by the use of nano-tech called morph, sesnors, self cleaning, stretchable electronics nano-fibres etc. Surprisingly, he had mentioned that since the use of nano-technology is too expensive, he is trying to evolve Nano Tech Libraries with less costly instruments whereby some unique systems of observation, analysis and clarification can be carried out in a morespeedy manner. He had also elaborated how nano technology can be applicable multidisciplinary areas like agriculture, medical diagnosis, environmental issues specifically relating to waste water management, reducing air pollution, gas sensors, solar cells and energy harvesting etc.
