Kapil's Nanotechnologys

  1. 1. Definition: Any technology that is based on a scale of nanometers (billionths of meters); any technology that is based on the placement or manipulation of single atom.
  2. 2. Simply stated, it is the world of the very small things, such as molecules and atoms.
  3. 3. “…our machines are evolving faster than we are. Within a few decades they seem likely to surpass us. Unless we learn to live with them in safety, our future will likely be both exciting and short.” Eric Drexler “Engines of Creation: The Coming Era of Nanotechnology.” 1986

  6. 6. How many people work in Nanotechnology? In the U.S., an estimated 2 million people work with nanometer-diameter particles on a regular basis in development , production and use of nanomaterials or products. [BLS, 2000]
  7. 7. The “Milli” world Millimeter – the width of the head of a pin How small is “Nano”? It is REALLY small. The “Macro” WorldThe “Macro” World Think of a child 5 feet tall which is about 1.5 meters. 5 feet = 1.5 meters 1.5 millimeters To get to the Milliworld divide 1 meter by 1,000 ÷ 1,000
  8. 8. The “Micro” WorldThe “Micro” World Micrometer - the diameter of microchips and red blood cells How small is “Nano”? Extremely tiny. The “Nano” worldThe “Nano” world Nanometer – the diameter of atoms and molecules
  9. 9. Nano World ! A picture of the nano world Using the scanning tunneling microscope (STM), electron formations can be viewed. Above, electrons are surrounded by 48 iron atoms, individually positioned with the same STM used to image them. The image was created and colorized at the IBM Almaden research laboratory in California We have already divided 1 meter 1 billion1 billion times to get to the Nano World

  26. 26. Ten Cate, DSM, TNO • feasibility study to evaluate present flexible armour systems • definition of new technological concepts for future flexible armour systems for the soldier It aims in particular at flexible armour systems based on polymer (nano)binder systems and shear thickening fluid binding systems which are used to retain high strength polymer fibers. An important part of this study is to define technologies which can improve existing systems and to define directions for flexible armour based on combinations of fiber, binder systems and nanoparticles. 37

  29. 29. The SensorCraft radar would combine air and ground moving target identification (GMTI), imaging and foliage- penetration applications; electro-optical/infrared sensors also would be used. Building a lightweight, low-cost sensor and then integrating it into the wing structure are key challenges on the radio frequency (RF) side, which is regarded as the most difficult aspect of SensorCraft. The active, electronically scanned radar must be lighter in weight—in the thousand-fold range—and much lower in cost than today’s technology. Using lightweight materials would enable affordable radars that are "five to six times bigger in area than what we have today," Key to the SensorCraft are load-bearing antennas, where the sensor becomes part of the wing, rather than a "parasitic" load bolted onto the airframe. The resulting antenna would be more susceptible to aerodynamic pressures—less stable than traditional structures. So engineers would embed sensors in the wing to track antenna movement and deformation in order for software to compensate for these factors. 44
