Nanotechnology (Sometimes Shortened to "Nanotech")
Nanotechnology

Nanotechnology (sometimes shortened to "nanotech") is the study of manipulating matter on an atomic and molecular scale. Generally, nanotechnology deals with developing materials, devices, or other structures possessing at least one dimension sized from 1 to 100 nanometres. Quantum mechanical effects are important at this quantum-realm scale. It is considered a key technology for the future and various governments have invested billions of dollars in its future. The USA has invested 3.7 billion dollars through its National Nanotechnology Initiative followed by Japan with 750 million and the European Union 1.2 billion.

Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale. Nanotechnology entails the application of fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, etc.

There is much debate on the future implications of nanotechnology. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in medicine, electronics, biomaterials and energy production. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials, and their potential effects on global economics, as well as speculation about various doomsday scenarios. These concerns have led to a debate among advocacy groups and governments on whether special regulation of nanotechnology is

    Currently, “nanotechnology development and production is geographically widespread, with more than sixty countries pursuing national nanotechnology research and innovation programs (Shapira and Wang, 2010), with the use and application of nanotechnology occurring globally. Regulation and oversight is primarily national, with some growth in nanotechnology information exchange, harmonization, and standards setting at supranational and international levels (Murashov and Howard, 2011), including activity by the OECD through its Working Parties on Nanotechnology (OECD 2011a) and on Manufactured Nanomaterials (OECD, 2012b). Arguably, some best practices are emerging (IRGC, 2007), but there remain significant differences by countries in the governance and regulation of nanotechnology. There are variations in the overall approaches to, and investment in, the assessment of environmental, health, safety, ethical, legal, and societal implications of…

    Whether society likes it or not, technology is advancing at a rapid pace towards the future. The technology in Ray Bradbury’s “The Veldt” and the furthering of nanotechnology are rudimentary compared to what advancements are to come. Most technological advancements will likely challenge what people deem ethical. With both benefits and detriments emerging from technology, it essentially plays a strong role in today's modern…

    Do you believe in technology? Or do you think that all inventions of scientists are worthwhile for humanity? Of course, lots of these inventions are helpful and useful. Also, some of them have created new periods in past. They played a big role for coming modernity. However, there are some inventions that seem very effective but they have brought new problems for humanity and environment. Especially, at the beginning of an invention, people don’t realize that it will become big problem. Nowadays, people are taking notice of this kind of things. Nanotechnology is one of these inventions which are needed to be discussed from point to point. Today, there are some people who believe that nanotechnology is dangerous; however some scientists think that nanotechnology has great benefits because it helps people to invent new things for the future.…

    Carbon Nanotubes

    Carbon nanotubes (CNTs) are a recently discovered allotrope of carbon. They take the form of cylindrical carbon molecules and have novel properties that make them potentially useful in a wide variety of applications in nanotechnology, electronics, optics, and other fields of materials science. They exhibit extraordinary strength and unique electrical properties, and are efficient conductors of heat. Inorganic nanotubes have also been synthesized. A nanotube is a member of the fullerene structural family, which also includes buckyballs. Whereas buckyballs are spherical in shape, a nanotube is cylindrical, with at least one end typically capped with a hemisphere of the buckyball structure. Their name is derived from their size, since the diameter of a nanotube is on the order of a few nanometers (approximately 50,000 times smaller than the width of a human hair), while they can be up to several millimeters in length. There are two main types of nanotubes: single-walled nanotubes (SWNTs) and multi-walled nanotubes (MWNTs). Manufacturing a nanotube is dependent on applied quantum chemistry, specifically, orbital hybridization. Nanotubes are composed entirely of sp2 bonds, similar to those of graphite. This bonding structure, stronger than the sp3 bonds found in diamond, provides the molecules with their unique strength. Nanotubes naturally align themselves into "ropes" held together by Van der Waals forces. Under high pressure, nanotubes can merge together, trading some sp2 bonds for sp3 bonds, giving great possibility for producing strong, unlimited-length wires through high-pressure nanotube linking…
