All Coprights Are Reserved,2010 …what is Nanotechnology technology is the useage and knowledge of tools, techniques or crafts or methods an area of science, research and technology concerned with extremely small things the study of controlling of matter on atomic or molecular scale the future of manufacturing technology based on manipulation of materials at the nano level Objects In Nano-Scale : Warrioirsoft INC. All Coprights Are Reserved,2010 Objects In Nano-Scale Nano Crystals Carbon Bondlength DNA structure Cellular level Slide 4: “ a process by which the ability to manipulate individual atoms and molecules is developed.” Warrioirsoft INC. All Coprights Are Reserved,2010 DEFINITION Concepts of NT : Concepts of NT Concept behind Nanotechnology : Warrioirsoft INC. All Coprights Are Reserved,2010 Concept behind Nanotechnology NT is the concept of engineering functional mechanical systems at the molecular scale. building machines at the molecular scale designed and built atom-by-atom. process by which the ability to manipulate individual atoms and molecules might be developed. History : History HISTORY : Warrioirsoft INC. All Coprights Are Reserved,2010 HISTORY first found in “There's Plenty of Room at the Bottom" a talk by physicist Richard Feynman. NT and nanoscience started in the early 1980s with Cluster Science and Scanning Tunneling Microscope (STM). Fullerenes in 1985 and Carbon Nanotubes later. Nano crystals, quantum dots and Atomic Force Microscope in the early 90’s. Current Research : Warrioirsoft INC. All Coprights Are Reserved,2010 Current Research Study of nanomaterials. Bottom-up approach methods : arranging smaller components into more complex assemblies. Top-down approach methods : creating smaller devices by using larger ones to direct their assembly. Applications : Applications Applications : Warrioirsoft INC. All Coprights Are Reserved,2010 Applications Medicine Chemistry and environment Energy Information and communication Heavy Industry Consumer goods Slide 12: Warrioirsoft INC. All Coprights Are Reserved,2010 Atomic Force Microscope Nano crystals Carbon Nanotube Nano Robots Implications : Implications Implications : Warrioirsoft INC. All Coprights Are Reserved,2010 Implications Potential risks of NT can broadly be grouped into three areas: Health issues - the effects of nanomaterials on human biology Environmental issues - the effects of nanomaterials on the environment Societal issues - the effects that the availability of nanotechnological devices will have on politics and human interaction NT And Computer Science : NT And Computer Science NT and Computer Science : Warrioirsoft INC. All Coprights Are Reserved,2010 NT and Computer Science University of California at Santa Barbara (UCSB) researchers have developed new nanoscale structures that will help to speed up computers. creating more powerful microprocessors that will use less energy. block co-polymer lithography techniques Nano-RAM, novel semiconductor devices novel optoelectronic devices, displays (carbon nanotubes), Quantum computers. Atomic Computers : Warrioirsoft INC. All Coprights Are Reserved,2010 Atomic Computers Optoelectronics Integrated Nano Processor And RAM Nano Sensors NT-Today And Tomorrow : NT-Today And Tomorrow Nanotechnology-today and tomorrow !! : Warrioirsoft INC. All Coprights Are Reserved,2010 Nanotechnology-today and tomorrow !! applied in almost all the sectors in today’s world : Diagnostics Drug delivery Tissue engineering Catalysis Filtration Aerospace Construction Refineries Consumer goods etc. Nanotechnology-today and tomorrow !! : Warrioirsoft INC. All Coprights Are Reserved,2010 Nanotechnology-today and tomorrow !! New application of NT expected in two to five years : Implantable devices that automatically administer drugs and sense drug levels. Cancer tagging mechanisms. Real time diagnostics for physicians. Sensors for airborne chemicals or other toxins. Improved solar cells and fuel cells. Faster, smarter and inexpensive computers. What We learnt ? : Warrioirsoft INC.
