Description
In 1960, Richard Feynman asked the question, What would happen if we could arrange atoms one by one the way we want them? Today, the emerging fields of nanoscience and nanotechnology are enabling control of the material world at the scale of atoms and molecules. Nanotechnology is inherently interdisciplinary and requires new approaches to undergraduate education through interdisciplinary connections between chemistry, physics, biology and materials science. Chemists can play an important part in this collaboration if the barrier of unfamiliar vocabulary is removed. Silicon chips, gigabyte disk drives, and light emitting diodes - devices that are based on atomically engineered materials - are all around us. These everyday wonders that we depend on would not be possible without the ability to "see" and manipulate materials at the most basic level, the individual atom. This workshop will focus on a chemical view of materials science and the nanoworld and how to incorporate these topics into the core curriculum. It will include a large number of hands-on activities, connections to commercial high technology materials, and laboratory experiments that do not require specialized equipment. Participants will receive a book, lab directions, and resources for class use.
