The Impact Of Nanotechnology In Our Lives

The Impact of Nanotechnology in Our Lives"Nanotechnology is science and engineering at the scale of atoms and molecules. It is the manipulation and use of materials and devices so tiny that nothing can be built any smaller." It refers to the use of materials with nanoscale dimensions, ranging from 1-100 nanometers. Nanotechnology impacts our lives today in many ways, such as economically, socially, environmentally, ethically, and more.Nanotechnology is used broadly in many ones' daily life. Many sunscreens containing nanoparticles of titanium oxide or zinc oxide can absorb and reflect UV light, while being transparent and allowing visible let through. EnviroSystems, Inc. developed a mixture named nano-emulsion of nanometer-sized oil drops mixed with bactericide, used in swimming pools as disinfectants. The oil particles adhere to bacteria thriving in water, making the delivery of the bactericide more efficient and effective. Tennis racket manufacturers introduce highly engineered products. Babolat introduced the VS Nanotube Power racket in 2002, made out of high modulus graphite with carbon nanotubes. They are 100x stronger than steel, yet one-sixth the weight. Nanotech tennis balls is made by coating the ball's inner core with 20 microns thick of layered sheets of clay polymer nanocomposites - each 1 nanometer thin, so that it remains playable for a long period of time.Nanotechnology has the potential to have major impact on the environment. An oil spill can be made harmless by the use of nanobots. They have fingers built from nanotubes, which can manipulate the atoms in an oil spill to render it nontoxic. Because of their small size, nanoparticles have more surface available for chemical interactions. Nanoparticles are being studied so that they could remove or destroy toxic substances from the environment. Researchers at Lehigh University have used nanoscale particles for groundwater remediation. These particles are made of iron, palladium and other noble metals, and have been shown to be very effective reductants for chlorinated hydrocarbons. Nucleation processes in air and water is possible, so as to the removal of the contaminants from both water and air. Water purification of seawater reverses osmosis, and a reactive surface coating destroys or immobilizes toxic compounds. Cost-efficient ways are provided to minimize the generation of waste from industrial processes. 'Green' chemistry eliminates these wastes using nanotechnology by synthesizing new and improved catalysts at the atomic level for industrial processes, building information into molecules which build new molecules; self-assembling molecules as the foundation for new chemicals and materials; and building molecules in micro scale reactors.The environment will also benefit from nanotechnology with the improvement of the efficiency of renewable energy. Atoms bonded together specifically could convert water with sunlight to hydrogen, promising a limitless and efficient energy...

The Influence of Interest Rates in our Lives

886 words - 4 pages Even though most of us may not realized it, interest rate actually play an important role in our everyday lives due to its great effect on the buying power. For instances, if the interest rate is higher, people tend to reduce their spending and rather save it in the deposit account due to the large interest that they can gained. However, if the interest rate is lower, they rather spend it than keeping it in the deposit account. The reason for

The Significance of Nanotechnology in Modern Society

937 words - 4 pages irrevocably, with nanotechnology both surrounding us and colonising our bodies. We will then inhabit an existence much like that described by Ray Kurweil in his books on the subject; as he puts it in the tagline to ‘The Singularity is Near’, we will have reached the point where humans will have transcended biology through our technology. From that point on, there is no way of telling where nanotechnology might take us. In the nearer future though, we can expect to be presented with the easier-to-digest phenomenon of items and devices that are smaller, lighter, stronger, faster and more efficient. That will probably be more than enough to cope with for now.
