  • 1. NANOTECHNOLOGY IN INDIAAND WORLD by V.ARJUNRAJ, B.E.,Mechanical Engineering(Manufacturing), Third year, Annamalai university-FEAT.
  • 2. Nanotechnology History: The first ever concept was presented in 1959 by the famous professor of physics Dr. Richard P.Feynman.  Invention of the scanning tunneling microscope in 1981 and the discovery of fullerene(C60) in 1985 lead to the emergence of nanotechnology. The term “Nano-technology" had been coined by Norio Taniguchi in 1974
  • 3. Nano • Size – 10-9 m (1 nanometer) • Border to quantum mechanics • Form → Emergent behavior 10010-9 10-6 10-3 103 106 109 m
  • 4. WHAT IS NANOTECHNOLOGY? Nanotechnolgy is the manipulation of matter at the nanometer scale(10-9). Examples.,Structures(Materials), Devices(sensors), Systems(NEMS). “Nanotechnology is an enabling technology that will change the nature of almost every human-made object in the next century.”
  • 5. How to produce nanoparticles? There are two approaches. • Top down method • Bottom up method Top down method: The bulk material is converted to small(nano) particles.eg.,Ball milling. Bottom up method: The gas phase into solid phase,that is from vapour to solid materials. The Carbon gas penetrates Chemical Vapour Deposition(CVD) chamber at certain temperature it can be converted into gas phase to solid material.
  • 6. Carbon nanotubes: (Graphene sheet)  4nm width(smaller diameter than DNA)  100x’s stronger than steel 1/6 weight  Thermal/electrically conductive  Metallic and Semi-Conductive Properties: Highest strength Electrical Resistance Thermal conductive View of Naked eye View of TEM
  • 7. Applications: In electric cables and wires In solar cells In fabrics
  • 8. Buckyballs-c60 Roundest and most symmetrical molecule known to man Compressed-becomes stronger than diamond Third major form of pure carbon Heat resistance and electrical conductivity Properties: They are smaller. They are Faster. They are lighter. They are Smarter.
  • 9. Applications: True age of Technology-Color TV. Faster computers are emerged.
  • 10. Quality of Product Manufacture in Nanotechnology Protection against wear for machinery Protection of soft materials Self-cleaning surface films • Corrosion protection Heat resistance Thermal insulation Biocompatible implants Anti-bacterial medical Super thin components for transistors Magneto-resistant sensors and data memory Anti-reflection screens Smaller and more efficient solar cell
  • 11. Future Nanotechnology: Carbon nanotubes (CNTs), will make airplanes and vehicles lighter and therefore help reduce fuel consumption; Novel lighting materials (OLED: organic light-emitting diodes) with nanoscale layers.(compared with traditional light bulbs = 5%); modern automobile tires for reinforce the material and reduce rolling resistance,. Self-cleaning or “easy-to-clean”-coatings wear protection products as fuel or motor oil additives could reduce fuel consumption of vehicles and extend engine life;
  • 12.  Nanomaterials could improve energy generation and energy efficiencies.  Nanomaterials can improve the efficiency of photovoltaic facilities;  Dye solar cells ('Grätzel cells') with nanoscale semiconductor  Nano optimized lithium-ion batteries have an improved storage an increased lifespan  Fuel cells with nanoscale ceramic materials energy production require less energy

  • 14. Nanotechnology used in various field: Mechanical Engineering/Robotics. National Security & Defense. Transportation. Aerospace. Medicine/Health. Food and Agriculture. Energy &Environment. Advance Materials & Textiles. Information Technology. Biotechnology.
  • 15. Today’s research in India: Filter the water in nanotechnology. Ready for this ‘Intelligent’ Or Biodegradable Diapers. New approach kills the Cancer cells. Today’s Research in World: Molecular manufacturing is coming soon. MNT (Molecular Nanotechnology) should probably be developed soon. Weapons and survillence can be made.
  • 16. Nanotechnology use in Mechanical Relative: In solar cells, for instance, photons can free electrons from a material, which can then flow as an electric current.The role of catalysts in a plethora of chemical reactions. improve photovoltaic solar electricity generation; improve solar thermal energy generation and conversion; improve solar-to-fuel conversions
  • 17. Solar Cell: There is no silver bullet – nanotechnology applications for energy  due toenergy generation, transformation, distribution, storage, and usage. nanomembranes have been used in the extraction and processing of fossil fuels and in nuclear power.
  • 18. IndustrialApplications of Nanotechnology: The use of engineered nanofibers already makes clothes water- and stain-repellent or wrinkle-free. It is used in surfaces and coating Lighter and stronger materials will be of immense use to aircraft manufacturers, leading to increased performance. Spacecraft weight is a major factor. Nanotechnology might thus help to reduce the size of equipment and thereby decrease fuel-consumption required to get it airborne. Nanoparticles can be injected into the material on soldiers’ uniforms to not only make the material more durable, but also to protect soldiers.
  • 19. Nanoweapon is the name given to military technology exploit the power of nanotechnology in the modern battlefield. Grey goo an uncontrollable, self-replicating nano- machine or robot. The use of vanadium and molybdenum nanoparticles improves the delayed fracture problems associated with high strength bolts.
  • 20. Summary: Nanotechnology can widely be used in solar cells, Automobiles, Military and Medicine for better beneficial purposes. This technology may be applied in bikes.  The body can be made of buckypaper composite. Buckypaper composite provides protection from lightning strikes while reducing overall weight. Buckypaper composite improve structural integrity. Buckypaper allows for wireless data transfer through the composite material. Buckypaper fuel cell is platinum $1x.No need traditional battery. The surface of a buckypaper bike stores energy,reducing weight and size.So it improves milage.
