What is Nanotechnology? : What is Nanotechnology? Nanotechnology is ... : Nanotechnology is ... Field of applied science whose theme is the control of matter on an atomic and molecular scale. How Small Is The Nano Scale? : How Small Is The Nano Scale? One nanometer (nm) is one billionth, or 10-9 of a meter. One human hair(cross section) is about 100,000 nanometers. Larger than Nanoscale is the microscale, and smaller than that is the atomic scale. Slide 6: History … Slide 7: "There's Plenty of Room at the Bottom“ Richard Feynman won a Nobel Prize for "fundamental work in quantum electrode Slide 8: In 1985, researchers reported the discovery of the "buckyball," a round molecule consisting of 60 carbon atoms. This led in turn to the 1991 discovery of a related molecular shape known as the "carbon nanotube" Carbon Nanotubes … : Carbon Nanotubes … Carbon nanotubes are molecular-scale tubes of graphitic carbon with outstanding properties. Length-to-diameter ratio greater than 1,000,000 The animation of a rotating carbon nanotube showing its 3D structure. Impact on Everyday Life : Impact on Everyday Life Nanotechnology was seen to have the second greatest impact, trailing only genetic engineering. Nanotechnology - The control of extremely small, sub-atomic matter: 22% NanoXplorer IDE … : NanoXplorer IDE … The nanoXplorer IDE application provides an integrated set of tools for designing, visualizing and simulating nanoscale components and devices, as well as researching nanotechnology in general. It is the essential software resource for nanotechnology workgroups. APPLICATIONS … : APPLICATIONS … MEDICINE : MEDICINE Nanomedicine Nanoshells Nano gels NANO ROBOTS : NANO ROBOTS Nanorobotics is the technology of creating machines or robots at or close to the microscopic scale of a nanometres (10-9 metres). CANCER TREATMENT : CANCER TREATMENT Cancer cells can be killed without the painfull side effects of chemotherapy. QuantumDot. Scientists may now be able to destroy tumors without killing healthy cells at the same time. Space Benefits of Nanotechnology : Space Benefits of Nanotechnology Improvement in shuttles Benefits to the Astronauts Cheaper space flights Nano satellites Improving Shuttles : Improving Shuttles Much Lighter in weight and smaller in size Nano sensors and Nano robots Use of Laser sails Micro and Nano-rovers for planetary exploitation Columbia Tragedy : Columbia Tragedy February 1, 2003 Columbia Space Shuttle disintegrated on its descend back to Earth First indication was the loss of temperature sensors on the left wing Foam struck the left wing There was loss of tire pressure warnings on the left main gear Indication of excessive structural heating Solution to Columbia Space Shuttle : Solution to Columbia Space Shuttle Biosensors Sensing device with a biological or biologically derived sensing element which is integrated with a physical transducer. Fabrication of overall space shuttle material that can Withstand 1000 degrees Celsius Nano sensors and Nano rovers with enhanced monitoring and efficient control of propulsion systems, life support, and higher mission success rates Nanotechnology for Astronauts : Nanotechnology for Astronauts Space suits Nano food Nanofood !?! : Nanofood !?! Preservation of food without refrigeration Protection of food from bacteria and diseases Lighter foods!!! Proposed Ideas : Proposed Ideas Nano Satellites Space Elevator Solar Sails NANO SATELLITES : NANO SATELLITES Nano satellites will be 90% lighter With much greater strength Greater safety margin due to the use of Diamondiod Fibres that NT can produce CARBON NANOTUBE : CARBON NANOTUBE Stiffest and strongest fibres known, with remarkable electronic properties and unique characteristics. They are the result of synthesis of buckminsterfullerene ,C60 and other fullerenes.
