Career Opportunities in Nanotechnology

NANO Technology is the future technology. It is the branch of science which works on the development and research of very minute products. NANO Technology has many chances in all sectors like Medical science, Agriculture, Pharmaceuticals, Defense, Industries, textiles, Engineering etc.      NANO Technology is most common in foreign but in India, this technology was just establishing. Can work in sectors like NANO Specialist, researcher etc.

      By the introduction of NANO Technology, we have achieved many sectors like Medical, Material science, electronics etc. Those who have completed +2 by 50% or more in Physics, Chemistry and Mathematics can attend the entrance examination. By this examination we can join for Integrated B Tech or M Tech courses. The duration of Integrated M Tech course is five years. Those who have completed B Tech (Mechanical, Electronics, Biomedical, Material science) can join M Tech.

Branches of NANO Technology are

• Molecular NANO technology
• D.N.A NANO technology

Application of Nana Technology

  Nanowerk Spotlight) Carbon nanotubes (CNTs) have great potential applications in making ballistic-resistance materials. The remarkable properties of CNTs makes them an ideal candidate for reinforcing polymers and other materials, and could lead to applications such as bullet-proof vests as light as a T-shirt, shields, and explosion-proof blankets. For these applications, thinner, lighter, and flexible materials with superior dynamic mechanical properties are required.

A new study by researchers in Australia explores the energy absorption capacity of a single-walled carbon nanotube under a ballistic impact. The result offers a useful guideline for using CNTs as a reinforcing phase of materials to make devices to prevent from ballistic penetration or high speed impact. Especially in making bullet-proof vests, shields, and explosion proof blankets, the best protective material will have a high level of elastic storage energy that will cause the projectile to bounce off or be deflected, i.e., the objective is to reduce the effects of 'blunt trauma' on the wearer after being struck by a bullet. We therefore tried to understand the impact behavior of CNTs. For a nanotube with one end fixed, the maximum nanotube enduring bullet speed increases and the energy absorption efficiency decreases with the increase in relative heights at which the bullet strikes; these values are independent of the nanotube radii when the bullet hits at a particular relative height.

For a nanotube with both ends fixed, the energy absorption efficiency reaches minimum when the bullet strikes around a relative height of 0.5. Bullet strikes the nanotube at a relative height of 0.31 (a) with both ends fixed and (b) with one end fixed. (Reprinted with permission from the American Institute of Physics) Specifically, we investigated the relationship between the nanotube radius, the relative position at which the bullet strikes, the bullet speed, and the energy absorbed by the nanotube for a particular bullet size and shape. A piece of diamond having 1903 atoms was used as a bullet with its speed varying from 100 to 1500 m/s. The bullet dimension was selected such that the width is larger than the width of the biggest nanotube after flattening. The bullet was released from a target about 15 Â from the center axis of the nanotube and moved at a constant speed in the horizontal direction i.e., perpendicular to the nanotube axis, as shown in the graphic above. The nanotube performance was examined for bullet released with various speeds at various positions using the classical molecular dynamics method.

 For a nanotube with one end fixed, the CNT could be resilient to projectile traveling at speeds of 200–1400 m/s (for comparison, the initial velocity of modern rifle bullets is somewhere between 180 and 1500 m/s, depending on gun and bullet type. For a typical over-the-counter gun the speed is below 1000 m/s); the nanotube enduring projectile speed increases whereas the absorption efficiency decreases with the increase in relative height ρ. For a nanotube with both ends fixed, the absorption energy reaches maximum whereas the absorption efficiency reaches minimum when the bullet strikes the nanotube in the middle.
