meaning and history of nanotechnology

Field of nanotechnology are terribly important in the production of various types. Field of nanotechnology has been intensely scrutinized and speculated about. This is the technique of building or making things with atomic precision. When every atom seriously planned and arranged in a given scheme of things, it produces a super device with many applications. Though, developments in the field is a new phenomenon, the core concept of this science were laid long back in 1950. Richard Feynman, Nobel Prize winner who laid the foundations of this field with a landmark address at the California Institute of Technology, in December 1959. He proposed the idea of ??technology, which will accommodate the volume of information at the point of a needle.

HISTORY

Nanotechnological concepts used since ancient times without actually defining science. Vulcanization of rubber, painting and various other processes used to use nanotechnological principles, even without realizing the larger significance of this technique. One nanometer is one billionth of a meter, which roughly amounted to ten atoms placed side by side. Appropriate device or to have dealt in part with a precision of less than 100 nanometers (nm) is included as a product of nanotechnology. James Maxwell first perform certain observations regarding the maneuvering of individual molecules by exploiting a concept known as 'Maxwell Demons'. Real effort to observe and measure the particles, conducted by Richard Zsigmondy by the analysis of gold sols. He was the first person to mark or classify particle sizes in the nanometer range.

Irving Langmuir won the Nobel Prize in chemistry, to introduce the world to the material with a thick layer of molecules. That Feynman, who was impressive in a speech in 1959, imagine the idea of ??space is not detectable by humans that can be used effectively. Manipulation of atoms and molecules is not achieved by the time he gave his speech. Therefore, this theory is only regarded as a fantastic visualization. That's just a decade later, that the world understand the implications of his statement. He has suggested the base-up approach to manipulate individual atoms of a material. He also offered a reward to solve the two challenges, the first is to create a 'nanomotor' to convert energy into motion to generate power at a very low order and the other for accommodation letters at the head of an encyclopedia of needle, with nanoscaling.

The first prize was won by William McLellan in 1960 and the latter is achieved by Tom Newman in 1985, when he wrote the novel in the area of ??25 000 by means of a needle point of an electron beam. Moore's Law, formulated based on the observation by Gordon Moore, also determine the impact of nanotechnology in building computers. He stated that the number of transistors on integrated circuits will be included to increase exponentially, so the performance of the circuit will double every two years. Every digital electronic devices that seem to obey Moore's law in terms of their speed memory capacity, operation or integration of external features. In fact, almost it seems, smaller device size, the larger is a feature embedded in it.

Behavior and handling of atoms and molecules studied by Dr Suntola further and assist in Finland. Dr Drexler, known for exploring nanoscale phenomena and devices has another interesting perspective on this field was called, 'Molecular Technology. "Richard Jones, published a simplified work on nanotechnology for the general reader, in which he describes various terms related to the branch. Current practices in nanotechnology enlists an exciting new initiative such as the use of bacteria to turn the spy plane and a small robot or plant viruses use to build the elements of nanotechnology. In the end, it would be fair to state, that researchers around the world are excited to bring the science of nanotechnology in the future, at a rapid pace.
