Materials Science and Nanotechnology for Chemists

George Lisensky (Beloit College) and Christopher Bailey (Wells College)

This workshop was offered July 26-31, 2015 by George Lisensky and Christopher Bailey at Beloit College.

It was previously offered in 2013 by George Lisensky and Christopher Bailey, in 2011 by David Brown at Southwestern College, and in 2004, 2005, 2007, and 2009 by George Lisensky and Karen Nordell.

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.

Beloit College, Beloit, WI 53511

Dates

The workshop schedule runs from dinner at 6:00 pm on Sunday, July 26, through lunch on Friday, July 31, 2015.

Travel by air

The Chicago O'Hare airport (ORD) is 85 miles from Beloit. There is almost hourly airport bus service available for $28 each way. See http://www.coachusa.com/CoachUsaAssets/files/103/madison.pdf for a schedule. If you give us your travel plans we will meet the Van Galder bus in South Beloit, Illinois and take you to campus. Milwaukee (70 miles) and Madison (50 miles) airports are also nearby but no public transportation is available from those locations.

Travel by car

Beloit is located at the border between Wisconsin and Illinois at the intersection of Interstate 90 and Interstate 43. There is no charge for parking on campus during the workshop.
Driving Directions

Housing
 
We will be staying in one of the campus residence halls. Each person will have their own room, with bathrooms/showers on the same floor. Rooms are air conditioned. Bedding, towels and washcloths are supplied. If you need a handicap accessible room please let us know. Indoor smoking is prohibited on campus.

Rooms will be available for check-in 2:00-6:00 on Sunday, July 26. If you will be arriving outside of these times please contact us to arrange check-in.

Food

Dinners will be in various locations, starting on Sunday, July 26. We will be eating breakfast and lunch in Chapin Hall beginning with breakfast on Monday, July 27 and ending with lunch on Friday, July 31. Mid-morning and mid-afternoon snacks will also be provided.
 
Dress/Clothing
 
All of the sessions associated with the workshop will be very informal and you should dress accordingly. We will frequently be in the lab so dress appropriately for experimental work. Safety glasses are required in the laboratory sessions; we will have some available but you may wish to bring your own.
 
Sessions
 
Presentations, experiments and discussions will be held on the fourth floor of our new Science Center. Elevator access is available at the south west corner of the building.
