What is nanoscience?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Nanoscience refers to structures that are 1?100 nm in size, of the order of a few hundred atoms.
  2. Nanoparticles, are smaller than fine particles (PM2.5), which have diameters between 100 and 2500 nm (1 x 10-7 m and 2.5 x 10-6 m).
  3. Coarse particles (PM10) have diameters between 1 x 10-5 m and 2.5 x 10-6 m. Coarse particles are often referred to as dust.
  4. (MS) Students should be able to make order of magnitude calculations.
  5. As the side of cube decreases by a factor of 10 the surface area to volume ratio increases by a factor of 10.
  6. Nanoparticles may have properties different from those for the same materials in bulk because of their high surface area to volume ratio. It may also mean that smaller quantities are needed to be effective than for materials with normal particle sizes.
  7. Students should be able to compare ?nano? dimensions to typical dimensions of atoms and molecules.
  8. Students should be able to calculate areas of triangles and rectangles, surface areas and volumes of cubes.
  9. Nanoparticles have many applications in medicine, in electronics, in cosmetics and sun creams, as deodorants, and as catalysts. New applications for nanoparticulate materials are an important area of research.
  10. Students should consider advantages and disadvantages of the applications of these nanoparticulate materials, but do not need to know specific examples or properties other than those specified.
  11. Students should be able to given appropriate information, evaluate the use of nanoparticles for a specified purpose
  12. Students should be able to explain that there are possible risks associated with the use of nanoparticles.

Keywords:
  • Volume ratio: The surface-area-to-volume ratio, also called the surface-to-volume ratio and variously denoted sa/vol or SA:V, is the amount of surface area per unit volume of an object or collection of objects. (1)
  • Surface area: The surface area of a solid object is a measure of the total area that the surface of the object occupies. (1)
  • Particles: You can use the idea of particles to explain the properties of solids, liquids and gases. (1)
  • Nanoparticles: Nanoparticles, are smaller than fine particles (PM2.5), which have diameters between 100 and 2500 nm (1)

AFL/Key Questions:
  1. What sort of structures does nanoscience refer to?
    Nanoscience refers to structures that are 1-100 nm in size, of the order of a few hundred atoms.
  2. What is the size of a fine particle and which is smaller, nanoparticles or fine particles?
    Nanoparticles, are smaller than fine particles (PM2.5), which have diameters between 100 and 2500 nm (1 x 10-7 m and 2.5 x 10-6 m).
  3. What is the diameter of coarse particles, such as dust?
    Coarse particles (PM10) have diameters between 1 x 10-5 m and 2.5 x 10-6 m. Coarse particles are often referred to as dust.
  4. What happens to the size of the surface area to volume ratio of a cube is you decrease the size of the sides by a factor or 10?
    As the side of cube decreases by a factor of 10 the surface area to volume ratio increases by a factor of 10.
  5. Why are the properties of nanoparticles different from those for the same materials in bulk?
    Nanoparticles may have properties different from those for the same materials in bulk because of their high surface area to volume ratio. It may also mean that smaller quantities are needed to be effective than for materials with normal particle sizes.
  6. How do nanoparticles compare in size to individual atoms?
    Nanoparticles are made of up to 1000 atoms or molecules, therefore their size is larger than that of an atom.
  7. What are the main applications of nanoparticles?
    Nanoparticles have many applications in medicine, in electronics, in cosmetics and sun creams, as deodorants, and as catalysts.
  8. What are the advantages and disadvantages of using nanoparticles?
    The advantages of nanoparticles are endless as they link to many new technilogies both commercially and medically however there are disadvantages as well. There are some concerns that nanoparticles may be toxic to people. They may be able to enter the brain from the bloodstream and cause harm. Some people think more tests should take place before nanoparticles of a material are used on a wider scale.
