Nanotechnology

Week 3 - Nanostructures and Nanomaterials

In this unit we will take our first look at the more common nanostructures and materials in use today. These include, but are not limited to, carbon, and carbon nanotubes, graphite, and diamond-like carbon, silicon structures and materials, metals and high performance alloys, and glasses and ceramics. For those of you with a background in materials science, this will be somewhat of a review. For those with no prior experience in materials, this will be an introduction to materials science, including basic structures and physical properties, physics of solids, and learning the basic similarities and difference of materials - based on their atoms, bonding, and short and long range order.
