Nanostructured ceramic coatings exhibit much greater toughness than conventional wear-resistant coatings for machine parts. Nanotechnology-enabled lubricants and engine oils also significantly reduce wear and tear, which can significantly extend the lifetimes of moving parts in everything from power tools to industrial machinery. Nanoparticles are used increasingly in catalysis to boost chemical reactions.
This reduces the quantity of catalytic materials necessary to produce desired results, saving money and reducing pollutants. Two big applications are in petroleum refining and in automotive catalytic converters. Nano-engineered materials make superior household products such as degreasers and stain removers; environmental sensors, air purifiers, and filters; antibacterial cleansers; and specialized paints and sealing products, such a self-cleaning house paints that resist dirt and marks.
Nanoscale materials are also being incorporated into a variety of personal care products to improve performance. Nanoscale titanium dioxide and zinc oxide have been used for years in sunscreen to provide protection from the sun while appearing invisible on the skin.
Electronics and IT Applications Nanotechnology has greatly contributed to major advances in computing and electronics, leading to faster, smaller, and more portable systems that can manage and store larger and larger amounts of information. These continuously evolving applications include: Transistors, the basic switches that enable all modern computing, have gotten smaller and smaller through nanotechnology.
At the turn of the century, a typical transistor was to nanometers in size. In , Intel created a 14 nanometer transistor, then IBM created the first seven nanometer transistor in , and then Lawrence Berkeley National Lab demonstrated a one nanometer transistor in ! Ultra-high definition displays and televisions are now being sold that use quantum dots to produce more vibrant colors while being more energy efficient.

Making flat, flexible, lightweight, non-brittle, highly efficient electronics opens the door to countless smart products. Be the first to write a review. Add to Wishlist.
Dubonos , I. Such outstanding toughness was attributed to a framework consisting of partially aligned CNTs and rGO sheets during solution spinning. The major obstacles concern the reproducibility and control of the basic mechanisms in order to predict and produce patterns with tunable size, periodicity and position and the new physical properties resulting from low dimensionality. Egeh Emmanuel, Unilag and Mr. DNA origami is a design technique — similar to the traditional Japanese art or technique of folding paper into decorative or representational forms — that is used by nanotechnology researchers to fold DNA strands into something resembling a programmable pegboard on which different nanocomponents can be attached. Importantly, after the reduction in hydroiodic acid, the rGO fibers presented a good conductivity of 2. Larger molecules, molecular aggregates, and forms of organized matter more extensive than molecules cannot be synthesized bond-by-bond.
