Nano Technology Shiva Prasad,shivaprasad.palle@gmail.com,+91-8008638988 Abstract: Defination : Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications. Encompassing nanoscale science, engineering and technology, nanotechnology involves imaging, measuring, modeling, and manip ulating matter at this length scale.” Why Nanotechnology? At the nanoscale, the physical, chemical, and biological properties of materials differ in fundamental and valuable ways from the properties of individual atoms and molecules or bulk matter. Size Matters How Big is a Nano? # Nano = 1 billionth;100,000 x’s smaller than the diameter of a human hair. Examples of Nanoscale A cubic micron of water contains about 90 billion atoms. A micron is one thousandth of a millimeter, and a thousand times larger than a nanometer. Another way to visualize a nanometer: 1 inch = 25,400,000 nanometers Disruptive Apps – Computing 1.Silicon is hitting its size limit, Moore’s law reaches maximum in 2007 2.SuperChips –Combination of Silicon and Galium Arsenide create wireless chips Disruptive Apps – Energy 1.Fuel cell technology becomes cost effective within 3 years. 2.Batteries that store more energy and are much more efficient Key Terms You Need to Know  BuckyBalls  Carbon Nanotubes  MEMS  Quantum Dots  Molecular Self Repair/Assembly  MRAM/Spintronics  Lithography Benefits of Nanotechnology : “The p ower of nanotechnology is rooted in its p otential to transform and revolutionize multiple technology and industry sectors, including aerospace, agriculture, biotechnology, homeland security and national defense, energy, environmental improvement, information technology, medicine, and transportation. Discovery in some of these areas has advanced to the point where it is now possible to identify applications that will impact the world we live in.” Current Applications: # medical diagnostics, displays, sensors, drug delivery, composite materials, solid state lighting, bio-materials, nano arrays, more powerful computers, protective armor, chem-bio suits, and chem-bio sensors Future Applications: # 2011-15 -- nanobiomaterials, microprocessors, new catalysts, portable energy cells, solar cells, tissue/organ regeneration, smart implants Obstacles and Hurdle  Funding Requires Long-Term Investments  Intellectual Property Issues - Patent Office that is Overwhelmed and Under-Qualified
