Presentation Transcript

  1. Nanoscience By: Caoimhe Malone

  2. What is nanoscience/nanotechnology • Nanoscience/nanotechnology involves studying and working with matter on an ultra-small scale • Nanoscience is used in nature, health, environment, new materials and economics

  3. The Nanoscale • One nanometre is one millionth of a millimetre • A single human hair is around 80’000 nanometres in width • A nanometre compared to a metre is equal to the size of a marble compared to the earth

  4. CRANN C: centre for R: research on A: adaptive N: nanostructures and N: nanodevices Located in trinity college Dublin TCD largest research institute

  5. CRANN’s AML • Advanced microscopy laboratory • The centre offers custom designed ultra high microscope operating environments • Dedicated wet and dry preparation labs • The facility can be accessed by non TCD academic students

  6. Nano in Nature • Nano science exists in many areas of nature • Gecko; Nano features enable them to climb and stick to almost any surface Nano hairs on the gecko’s toes enables them to stick to anything due to friction and adhesion.

  7. Nano in Nature • The Morpho Butterfly • wings of Morpho create colour by diffracting and scattering light • Many butterflies use light interacting on their wing scales to produce colour

  8. Nanotechnology • Nanotechnology involves designing/making objects on a nanoscale • Its aim is to make products lighter, stronger, cleaner, cheaper and more precise. • Products can include skin care, tennis balls, foot warmers, foot products.

  9. Nanoscience and Materials • Nano materials are the products of nanotechnology • Nanomaterial's are produced by controlling structure dimensions on a nanoscale to produce new materials • Nanomaterials are studied at a nanoscale • Their properties differ from those in bulk materials

  10. Nanomaterials Examples are nanoscale particles, tubes and rods. Nanorods Nanotube Nanoparticles

  11. Studying Nanoscience • Educational programme offered by CRANN to secondary school students • It will introduce senior students in school to Nano science which is planning to become part of leaving cert syllabus • For college; nanoscience, physics and chemistry requires a min. of 475 points with 10 places avalible in TCD

  12. Bibliography • CRANN TCD “nano in my life” • TCD college courses • Images downloaded from “google images”
