In the case of blood diseases, systemic cytotoxicity could be reduced by targetting drugs to lymphocytes. Nanotechnology offers such targeted drug delivery system. [Buxton, 2006]
Electronics
Nanotechnology will usher a quantum leap in computing. In fact, with nanotechnology quantum computing will be a reality very soon. Computers based on nanowires or nanotubes would have super-computing power but still be handheld. Carbon nanotubes are highly conductive and are better than copper. They also have semi-conducting properties. Thus far, the realization of building nanoscale electronic circuits using carbon nanotubes had been a problem. However, researchers at Caltech have already designed and built 'nanowire-based circuits'. Dr. Hongjie Dai, professor at Stanford University says "the move to CMOS with nanowires is important if nanowires are to be used for future electronics applications." [Kevin Bullis]
Green Nano
Environmental considerations are at the center of our growing world and nano technology offers the promise of not only environment friendly production but also the possibility of environmental decontamination using engineered nanospheres. Recent research by Lehigh University has attested that nanoscale iron could clean up groundwater and contaminated soil by as much as 96%. Nanospehres or molecular cages can be designed to trap environmentally toxic substances with promises of environmental decontamination. [Eva Gutierrez]
Aerospace
Carbon nanotubes are the focus of aerospace industry because of their special electrical and mechanical properties. They are 100 times stronger than steel at one sixth the weight. Several studies have shown that carbon nanotubes are ideal building material because of their high tensile strength and low weight. Further, the high conductive nature of carbon nanotubes makes them highly suitable for aviation electronics. [Belluccia et.al] as Dr. Bourne, from the NRC Steacie Institute for Molecular Sciences (NRC-SIMS) in Ottawa says, "If we can show that these carbon nanotube composites can perform as expected in these applications, then this will go a long way to validating their use in the really big market - aerospace." [NRC]
Conclusion
Nanotechnology represents a huge wave in the world of science and technology with its applications extending into multiple domains. Designing and developing products at the molecular level offers a wide range of choices that could be beneficially...
Desire to Attend MIT Why I Desire To Attend MIT "Life's challenges are not supposed to paralyze you, they're supposed to help you discover who you are" (Reagon, 2010, ¶ 1). Challenges in life have helped me not only discover who I am, as the introductory quote by Reagon (2010), an American historian and musician, asserts. They also strengthen and help me realize who I can become; a person who actively approaches life
They are used to the existing state-based system of commercial regulation, and there are several reasons why they might wish to maintain it. The advantage of using this system is that the MNCs know the system well, and the system uses effective tools for managing and currently provides them with significant leverage. They have proved adept at using leverage: globalization has forced firms to raise efficiency and adopt cost-minimization
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
Robotics The popular concept of robots has been colored by stories of mythical mechanical beings dating back to antiquity, and fictional robots (remember "R-2 D-2?") depicted in popular science fiction movies such as the Star Wars. Robotics, however, is a serious technology that deals with the design, construction and operation of robots that are used in numerous applications ranging from industries that require accurate and repetitive tasks (such as the car
Technology in Use in 1910 and the Technology in Use Today Technology during 1910 and its rapid evolution to the present era: The 19th century witnessed major upheavals in science and technology ushering a gamut of changes and widespread ripple effect on the society. The dawning of science in industry brought about by the Industrial Revolution was a watershed in global technology that continued to shape the future of mankind. It
