Science Ideas and Concepts

Scientific study requires a basic knowledge and understanding of ideas and concepts. This collection explains the ideas that are fundamental to Nanoscience.

  • Chemical reactions and catalysts – Information Sheet

    This is an introduction to chemical reactions and factors affecting their rate, and catalysts – substances that change the rate of a chemical reaction but are chemically unchanged.

  • Nanometres and nanoscale – Information Sheet

    A nanometre is a billionth of a metre. Nanoscale can refer to things less than 100 nanometres in size, or to materials so small that they behave differently to normal.

  • Seeing atoms – Information Sheet

    The development of nanotechnology is linked to new kinds of powerful microscopes. Electron microscopes and scanning probe microscopes are new tools that enable scientists to see nanoparticles and individual atoms.
