Nanotechnology, as its name implies, is, at its essence, the science of small things. However, nanotechnology is not so much the study of small things as it is the study of how to use small things to advance technology. "Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced" (Center for Responsible Nanotechnology, 2002-2008). It spans a very broad range of topics. For example, the use of powder coat paint to provide a smooth finish to lawn furniture falls under the umbrella of nanotechnology, as does some use of tiny robots in surgery. The field is so vast that its different applications may seem unrelated. However, if the scientific question at the heart of the issue involves examining things at a molecular scale, then it is an element of nanotechnology. It is impossible to determine exactly when nanotechnology was discovered. That is because nanotechnology was being used before it was defined as a modern science. For example, 4th century dichroic glass was an example of how craftsmen used heat to manipulate things on a molecular level, which is an element of nanotechnology (National Nanotechnology Initiative, 2013). The advent of modern technology can be said to have begun in 1857 when Michael Faraday discovered colloidal ruby gold (National Nanotechnology Initiative, 2013). In 1936, Erwin Muller invented the field emission microscope, which...
In 1947, John Bardeen, William Shockley, and Walter Brattain discovered the semiconductor transistor, which helped usher in the electronic age, which has been interrelated with nanotechnology (National Nanotechnology Initiative, 2013). In 1956, Arthur von Hippel coined the term "molecular engineering" in discussing dielectrics, ferroelectrics, and piezoelectrics; molecular engineering could be seen as a precursor to nanotechnology. However, it was a 1959 speech by Richard Feynman, in which he discussed engineering on an atomic scale, that is often hailed as the start of nanotechnology (National Nanotechnology Initiative, 2013). The field was given its name in 1974 by Tokyo Science University Professor Norio Taniguchi (National Nanotechnology Initiative, 2013).
Nano Technology and World of Quantum Physics Nano technology pertains to the restructuring and reconstruction of atomic and molecular nature. It involves studying the phenomena and materials of atomic manipulation to transform and construct new materials, devices, living organisms and improved technological systems that are
Nano Science - Tomalia In the lecture that Dr. Donald Tomalia presented in March, 2009 ("Traveling the Nano Road of Science, Art & Discovery"), he seems to be the most enthusiastic when he is talking about "dendrimers," which are polymers with a central and hollow core and tendrils. Because the core is hollow in a dendrimers it becomes a kind of pouch or cavity, he explains, and other molecules can be
Technology and Global Ecosystem An Analysis of the Implications of Technology and the Global Ecosystem The 21st century promises to usher in innovations in technology that cannot yet be imagined, and the advancements to date have provided many in the world with unprecedented standards of living. Improved methods of transportation and communication, combined with more leisure time than ever in which to spend it has resulted in many people developing a keen
2010; Chorny et al. 2010). This research is still quite new, however, and the question remains as to whether or not nanoparticles can truly serve as a replacement for stents by prohibiting plaque growth through a variety of means, including more targeted and longer-range delivery of pharmaceutical substances that destroy such build-ups and inhibit plaque deposits from forming. The efficacy of this approach has already been preliminarily demonstrated, but
Nanotechnology attempted to show the potential of this new technology and included the wide range of fields that are connected to the concept of the nanometer scale. These include machining, imaging, metrology or measurement, micromachines, instrumentation and machine tools, scanning probe microscopy, fabrication of components, nanoelectronics, molecular engineering, among others. (Journal Review: Nanotechnology) Another important step in the development of this technology in both a practical and theoretical sense was
People's Car Tata Nano Financial, political and marketing/business commentators alike seem to agree that the Tata Nano, the planet's cheapest car, was a perfect match between an idea and a need when it was introduced -- or at least as a manufacturing idea. Making the smallest of small cars could happen because the timing was right for pairing just such an idea with the quickly emerging appreciation of frugal engineering innovations,
