Ion beams were used for many years for characterizing and reading fabrics. Now full of life ion beams are offering how one can regulate the fabrics in unparalleled methods. This booklet highlights the emergence of high-energy quick heavy ions as a device for tailoring the houses of fabrics with nanoscale constructions. fast heavy ions engage with fabrics through exciting/ionizing electrons with out at once relocating the atoms. This opens a brand new horizon in the direction of the 'so-called' tender engineering. The ebook discusses the ion beam know-how rising from the non-equilibrium stipulations and emphasizes the ability of managed irradiation to tailor the homes of varied varieties of fabrics for particular needs.

This approach represents a maskless process that combines the top-down and bottom-up patterning methods, and no chemical etching or pattern transfer steps are involved. Nano patterns can be generated using focussed ion beam (FIB) induced adhesion, by selective irradiation of thin metallic films grown on substrates by focussed ion beam followed by peel off. After peel off of the irradiated thin film, the ion beam scanned portions are retained on the substrate, creating nano patterns. The method is suitable for materials of which the adhesion to the substrate can be improved by ion bombardment [124].

Ion beams are opening various possibilities in the direction of tailoring the properties of materials towards certain functional goals. Basically FIB patterning techniques rely on a sequential process which can be used in manufacturing. FIB instruments combine high resolution patterning by local irradiation and imaging by Scanning Ion Microscopy. This can be turned into a process of unattended–automatic batch operation having self diagnostic and repair capability. There seem to be unlimited possibilities for nanostructuring materials.

In order to examine this point we have to concentrate on the fact that the ion-matter interaction at the nano level is not yet fully analyzed. The crucial aspect of nanophysics is that scaling does not hold.
