Paper Presentation & Seminar Topics: Nanotechnology


Abstract : Seminar Nanotechnology, or, as it is sometimes called, molecular manufacturing , is a branch of engineering that deals with the design and manufacture of extremely diminutive electronic circuits and machinelike devices built at the molecular take of matter. The Institute of Nanotechnology in the U.K. expresses it as \"science and technology where dimensions and tolerances in the range of 0.1 nanometer (nm) to 100 nm play a critical role.\" Nanotechnology is ofttimes discussed together with micro-electromechanical systems ( MEMS ), a subject that usually includes nanotechnology but may also include technologies higher than the molecular level.There is a limit to the number of components that can be fabricated onto a conductor wafer or \"chip.\". Traditionally, circuits hit been etched onto chips by removing material in diminutive regions. However, it is also doable in theory to build chips up, one atom at a time, to obtain devices much smaller than those that can be manufactured by etching. With this approach, there would be no superfluous atoms; every particle would hit a purpose. Electrical conductors, titled nanowire s, would be exclusive one atom thick. A logic gate would require exclusive a few atoms. A accumulation bit could be represented by the presence or epilepsy of a single lepton .Nanotechnology holds promise in the hunt for ever-more-powerful computers and subject devices. But the most fascinating (and potentially dangerous) applications are in medical science. So-called nanorobot s might serve as programmable antibodies. As disease-causing bacteria and viruses mutate in their long attempts to intend around medical treatments, nanorobots could be reprogrammed to selectively essay discover and destroy them. Other nanorobots might be programmed to single discover and kill cancer cells.Two concepts related with nanotechnology are positional gathering and self-replication . Positional gathering deals with the mechanics of agitated molecular pieces into their proper relational places and ownership them there. Molecular robots are devices that do the positional assembly. Self-replication deals with the problem of multiplying the positional arrangements in some automatic way, both in antiquity the manufacturing device and in antiquity the manufactured product.
