Nanotechnology is a field of research and innovation concerned with building 'things' - generally, materials and devices - on the scale of atoms and molecules. A nanometer is one-billionth of a metre: ten times the diameter of a hydrogen atom. The diameter of a human hair is, on average, 80,000 nanometers. At such scales, the ordinary rules of physics and chemistry no longer apply. For instance, materials' characteristics, such as their colour, strength, conductivity and reactivity, can differ substantially between the nanoscale and the macro. Carbon 'nanotubes' are 100 times stronger than steel but six times lighter.
Nanotechnology is science, engineering, and technology conducted at the Nano scale, which is about 1 to 100 nanometres. Nano science 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 Nano science 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 (Cal Tech) 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 tunnelling microscope that could "see" individual atoms that modern nanotechnology began.
Nanotechnology offers the potential for new and faster kinds of computers, more efficient power sources and life-saving medical treatments. Potential disadvantages include economic disruption and possible threats to security, privacy, health and the environment.
This is a 2-year post-graduation course which involves in studying the nature of matter on a molecular or an atomic level. Nanotechnology is a new dimension in this field of engineering. Nanotechnology includes the study of science, engineering, and technology.
The minimum requirement for the master’s degree is an undergraduate degree in engineering or technology with an aggregate score of 50% can apply for this course. Admission into reputed institutes such as IITs, NITs, and VIT can be obtained by appearing for an entrance exam like GATE.
M.Tech Nanotechnology is a 2-year post-graduate course. Examinations are held at the end of each semester. Direct admission through management quota is also available in a very few of the private colleges, but the admission fee will be very high.
M.Tech Nanotechnology Scope
Pursuing M.Tech after B. Tech gives sufficient time to get deep technical knowledge of the subject and have more control over it. After completing Master’s in Nanotechnology, candidates can choose the career in nanotechnology in various industries such as auto and aerospace industry, forensics etc. Presently nanotechnology has become a dynamic and expanding research area. Some of the M.Tech Nanotechnology jobs are:
- Engineering companies
- Food and beverages
- Space research
- Military and national security
- Electronics industry
- Materials sciences
- Aerospace industries
- Medical Scientist and Technician etc.
