Thermal Analysis of Plastics Teresa D'Amico, Craig J. Donahue, and Elizabeth A. Rais
Students interpret previously recorded scans generated by differential scanning calorimetry and thermal gravimetric analysis to investigate a polypropylene dog bone, a polyethylene terephthalate pop bottle, the plastics in automobile head- and taillights, fishing line and a tea bag, and the rubber tread of an automobile tire.

A Green Polymerization of Aspartic Acid for the Undergraduate Organic Laboratory George D. Bennett
Based on a technology that won a Presidential Green Chemistry Challenge Award, this experiment involves the thermal polymerization of aspartic acid and subsequent hydrolysis to give sodium poly(aspartate). The procedure is suitable for introducing students to the important topic of polymers and for illustrating several of the principles of green chemistry.

Introduction to Photolithography: Preparation of Microscale Polymer Silhouettes Kimberly L. Berkowski, Kyle N. Plunkett, Qing Yu, and Jeffrey S. Moore
In this experiment, a glass microscope slide acts as the microchip. Students can pattern this "microchip" by layering negative photoresist on the slide using a solution containing monomer, crosslinker, photoinitiator, and dye. The students then cover the photoresist with a photomask, which is the negative of a computer-generated image or text printed on transparency film, and illuminate it with UV light. The photoresist in the exposed area polymerizes into a polymer network with a shape dictated by the photomask. The versatility of this technique is exemplified by allowing each student to fabricate virtually any shape imaginable, including his or her silhouette.

Hands-on Classroom Photolithography Laboratory Module To Explore Nanotechnology Scott J. Stelick, William H. Alger, Jesse S. Laufer, Anna M. Waldron, and Carl A. Batt
Teaching nanotechnology in the high school and undergraduate environment is a challenge given the typical expense of instruments used to create micro- and nano-sized devices. To meet this challenge, a portable optical reduction stepper was designed, fabricated, and optimized for use in classrooms. This unique system was designed to provide a safe, hands-on experience for students to create microscale circuits using photolithography. Students are able to design, fabricate, and test a circuit with dimensions as small as 100 mm.

Polymers (Oxford Chemistry Primers No. 85) (David Walton and J. Phillip Lorimer) John H. Shibata
Although the title suggests a broad, general coverage of polymers, in reality this book focuses primarily on synthesis and the macroscopic properties of polymers. A significant portion of the book emphasizes practical considerations of polymerscommercial aspects determined by the properties of polymers and the industrial processes for polymer synthesis and three-dimensional network formation. In many cases, specific polymer types and materials are described in detail. The concreteness of explicit examples to illustrate the principles of polymerization and the properties of networks and functional polymers are appropriate for readers seeking a practical introduction to polymers.
