Abstract

Generally, nanotechnology deals with developing materials, devices, or other structures possessing at least one dimension sized from 1 to 100 nanometres. Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to investigating whether we can directly control matter on the atomic scale. India enjoyed prosperity and fame as for the production of steel, since 300 BC to the 17th century, exporting it across the world. Indian craftsman used unique smelting techniques to manufacture the wootz ingots, which led to nanotisation giving a unique long lasting edge to Damascus blades made of Indian ingots. Wootz also had a high percentage of carbon, which was introduced by incorporating wood and other organic matter during fabrication. India, for ages, was a leading exporter of this steel, which was used to make Persian daggers and was quite popular in Europe, centuries ago. Studying the medieval Damascus swords made of ingot exported from south India to Middle East, researchers found that medieval smiths used, may be for the first for the first time, what we call today as “nanotechnology”. The steel of the legendary blades which includes cementite in its structure, nonowires, carbon nanotubes and other extremely small, intricate structures, might explain the unusual hardness, sharpness and banding of the blades. Banding was famous amongst the warriors as Mohammad ladder are prophet ladder which gave moral and mental strength in war.
