MAY, 20216 The Evolving World of NanotechnologyEditorialUnprecedented opportunities are arising for re-engineering existing products. For example, clusters of atoms (nanodots, macromolecules), nanocrystalline structured materials (grain size less than 100 nm), fibers less than 100 nm in diameter (nanorods and nanotubes) and films less than 100 nm in thickness provide a good base to develop new nanocomponents and materials.The buckyball (C60) has opened up an excellent field of chemistry and material science with many exciting applications due to its ability to accept electrons. Carbon nanotubes have shown a promising potential in the safe, effective and risk free storage of hydrogen gas in fuel cells, increasing the prospects for its wider use and the replacement of the internal combustion engine. Nanotechnology offers a myriad of applications including new gas, optical and chemical sensors, energy conversion devices and bio implants.Nanograin-size, enhanced diffusivity and concentration of defects would make grain boundary sensitive to attack by corrosion. Increased electrical resistivity due to electron scattering would enhance corrosion resistance. Increased number of grain boundaries would also lead to development of more anodic sites for nucleation of corrosion.Theoretically, the structural evidence does not present an optimistic picture of corrosion resistance. There is no clear evidence to prove that nanomaterials are more resistant to corrosion than conventional materials. This is in contrast to the corrosion prevention of nanostructured materials as the studies on coatings have proved. Nanoparticles incorporated in coatings have shown a dramatic resistance to corrosion of the substrate due to their hydrophilic, anti-wear, anti-friction and self-cleaning properties. Engine components are subjected to severe environmental stimulus for corrosion. Diesel engines produce sulfuric acid and formic acid as combustion products. Nano zirconia powder has been used to coat engine components by plasma spray with success. Nanocoatings create a lotus effect and properties which keeps corrosion away.For many, nanotechnology is viewed as merely a way to make stronger and lighter tennis rackets, baseball bats, hockey sticks, racing bikes, and other athletic equipment. But nanotechnology promises to do so much more. A more realistic view is that it will leave virtually no aspect of life untouched and is expected to be in widespread use by 2022. Mass applications are likely to have great impact particularly in industry, medicine, new computing systems, and sustainability.Let us know your thoughts.Rachel SmithManaging Editoreditor@appliedtechnologyreview.comCopyright © 2021 ValleyMedia Inc.
