Show all resources
  1. Welcome students and briefly review their progress with the Nano House research assignment.
  2. Investigation –Much of the earlier focus of the course has been on how Nano technology is being used to make our lives easier and more comfortable. However Nano technology can improve our lives in other ways as it is capable of improving the environment as well. Teacher introduces PowerPoint L7.1 Safety and Ethical Issues.pptx Resources
  3. Investigation – Discuss the features of Photonic Crystals as introduced in the article “Butterfly's Interconnected Nano-Scale Coiled Springs Inspire Development of Unique Photonic Crystal Device”. Resources
  4. Discussion – Teacher introduces Photonic Crystals and how they have the potential to provide a new class of optical materials which have the capability of revolutionising optical communication networks. Reference the info from Photonic Crystals - Down Under. Resources
