- 3. Introduction to Nanotechnology Nanotechnology has enormous potential to change society and it involves manipulation of objects on the automic level. The products will be build on every atom that are stronger, smarter, cheaper, cleaner, and more precise. Nanotechnology is the art and science of manipulating matter at the nanoscale (down to 1/100,000 the width of a human hair) to create new and unique materials and products
- 4. Origins of Nanotechnology Noble prize winner Richard Feynman first conceived the idea of molecular manufacturing in his 1959 speech, “There's Plenty of Room at the Bottom." Richard Feynman was the first scientist to suggest that devices and materials could someday be fabricated to atomic specifications In 1986, K. Eric Drexler wrote "Engines of Creation" and introduced the term nanotechnology from there Scientific research really expanded over the last decade
- 5. Definition of Nanotechnology “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 manipulating matter at this length scale.”
- 6. A nanometer is… one billionth of a meter How Small Is Nanoscale? Human Hair: Approx. 1x105 nm DNA Sample: Approx. 2 nm
- 7. 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. Nanotechnology R&D is directed toward understanding and creating improved materials, devices, and systems that exploit these new properties.
- 8. What is nanomaterial? Is defined as any material that has unique or novel properties, due to the nanoscale ( nano metre- scale) structuring. These are formed by incorporation or structuring of nanoparticles. They are subdivided into nanocrystals, nanopowders, and nanotubes: A sequence of nanoscale of C60 atoms arranged in a long thin cylindrical structure.
- 9. example Category of nanomaterials layers, multi-layers, thin films, platelets and surface coatings. They have been developed and used for decades, particularly in the electronics industry. One-dimensional nanomaterials nanowires, nanofibres made from a variety of elements other than carbon, nanotubes and, a subset of this group, carbon nanotubes. Two-dimensional nanomaterials are known as nanoparticles and include precipitates, colloids and quantum dots (tiny particles of semiconductor materials), and Nanocrystalline materials Three-dimensional nanomaterials Nanomaterials’ Characteristics

Editor's Notes
- #6: 1. Its a bit difficult to realize how small the nano-scale is. To make things easier to get, we can say that one nanometre (nm) is one billionth of a metre. -2. Lets see some examples to make it clear In the picture on the right, we can see a man staring at his picked hair trying to figuring out the diameter of it, he will essentially come to the conclusion that a human hair is 100,000nm thick, while a DNA molecule is only 2 nms wide.
- #11: e.g: in da field of electronics nanotransistors are becoming more nd more popular bcoz of it’s compactness.. If u are thinking that this is a single transistor then you need to reshape your thinking, bcoz this is a transistor box containing thousonds of transistors in it… Some other examples of nanoelectronics are Nanodiodes, OLEDs etc.
- #12: The aapliances made with the help of nanoelectronics are getting its market share increasing and are becoming popular day by day due to the productivity and quality they have. Such as plasma Displays nd Quantum computing..
- #13: 1-This is a nano-engineered battery, light in weight and flexible just like a paper. It can be rolled, twisted, folded or cut into a number of shapes with absolutely no loss of mechanical efficiency. Other energy suppliment examples with some change in their properties are fuel cells and solar cells
- #14: 1-this rotating picture is actually a model of carbon nanotube, the strongest and stiffest materials discovered till to date. These tubes are the building block of almost all the NT objects. 2- Aerogel. The world’s lightest crystalline solid 3-and nano particles
