MODULE -1 The World of small Dimensions: Introduction : Questions to be considered :: • What is a nanoparticle? An example is a bucky ball – In 1985, a team led by Harry Kroto, Richard Smalley and Bob Curl discovered that carbon atoms could be made to aggregate into clusters containing 60 (or sometimes 70) atoms. They deduced that the structure of the C60 molecule was a hollow sphere, as shown in Figure below, and it was named ‘Buckminster fullerene‘ (or, more affectionately, Buckyball) because of the resemblance of the structure to the architectural designs of the architect Buckminster Fuller. 60 carbom atoms Joined in one unit. = 1nm (1 nano meter) - 10 Hydrogen atoms linked in one unit. • - How big is a nanometre? It is a million times smaller than the smallest measurement you can see on a ruler! (mm) It is a millionth of a millimetre or a billionth of a metre • How big is a nanometre? 1 nm = 10-9 m 1m = 103 mm = 106 microns 1 micron = 10-6 m
• • • A human fingernail grows 1 nanometre every second. A man’s beard grows 5 nanometres every second. This is a silver nanowire resting on a human hair. Look at a strand of your own hair and imagine how small that is… • - What is a nanoscience? Way back in 1959, a physicist named Richard Feynman shared his vision of what very small things would look like and how they would behave. In a speech at the California Institute of Technology titled “There’s Plenty of Room at the Bottom,” Feynman gave the first hint about what we now know as “nanoscience” [1]: The study and manipulation of materials at the nanoscale . nanoscience is the study of the behavior of objects at a very small scale, roughly 1 to 100 nanometers (nm). • - Why nano? At the nanoscale, strange things happen to materials – their properties can change. Reactivity - As particles get smaller they tend to react differently with their environment than larger particles.
