Electropolymerized Conducting Polymer as Actuator and Sensor Device: An Undergraduate Electrochemical Laboratory Experiment  María T. Cortés and Juan C. Moreno
A trilayer formed by two conducting polymer films sandwiched around an adhesive polymer layer works as actuator and sensor simultaneously. This device can be bent up to 180 and it can be used as a sensing device of physical chemistry parameters such as cell temperature and electrolyte concentration. In this article, it is shown in a didactic way how to electrochemically synthesize ClO4-doped polypyrrole (PPy) films, how to fabricate a trilayer device, and how to evaluate its actuating and sensing capabilities. The required materials are simple and a complicated setup is not necessary.

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.

Self-Assembled Colloidal Crystals: Visualizing Atomic Crystal Chemistry Using Microscopic Analogues of Inorganic Solids  Neal M. Abrams and Raymond E. Schaak
Monodisperse spherical colloids spontaneously crystallize into close-packed crystals, in analogy to the simple crystal structures of many of the elements. Since colloids are orders of magnitude larger than atoms, students can directly observe crystal structure and behavior in a microscope using colloidal crystals. This laboratory exercise provides a modular series of materials science experiments appropriate for undergraduate chemistry and engineering majors. The individual modules include aspects of chemical synthesis (monodisperse SiO2 and polymer spheres), self-assembly (colloidal crystallization), and structural characterization through microscopy (optical and scanning electron microscopies) and optical spectroscopy (optical diffraction and UVvisible spectroscopy).

Measuring Viscoelastic Deformation with an Optical Mouse  T. W. Ng
A simple demonstration of viscoelasticity can be carried out by attaching a weight to a polymer film and watching it extend over time. For accurate and quantifiable data on the deformation, an electronic displacement sensor should be incorporated. Most of such sensors are expensive. Here, an optical mouse was demonstrated to provide accurate data at low cost. The experiment was also devised in a manner to allow students to learn about viscoelastic deformation experientially.

Using Organic Light-Emitting Electrochemical Thin-Film Devices To Teach Materials Science  Hannah Sevian, Sean Müller, Hartmut Rudmann, and Michael F. Rubner
Light-emitting thin films provide an excellent opportunity to learn about principles of electrochemistry, spectroscopy, microscopic structure of the solid state, basic circuits, and engineering design. There is currently strong interest in academic and industrial engineering research centering on developing organic light-emitting devices for applications in flat panel displays. In this educational module, designed for high school or introductory undergraduate courses, students learn how to make a ruthenium-based thin-film device. In the process, they learn about the solid-state electrochemistry at work in the film, as well as the electroluminescence that results when current passes through the device.

An Inexpensive Kit for Constructing Models of Crystals  Michael Laing
This simple kit comprises five trays, each of 25 square wells, and a lid. It can be used to construct primitive cubic, FCC, BCC, diamond, zinc blende, NaCl, CsCl, rutile, fluorite, perovskite structures. The trays are square tissue culture Petri dishes (multiwell plates). Atoms are represented by glass marbles.

Report on the WPI Conference: General Chemistry and Materials Science: The Interrelationships  Herbert Beall
Of the recent accomplishments of chemistry, some of the most spectacular have been in the area of materials. Materials receive surprisingly little attention as examples of chemical phenomena in fundamental chemistry classes, which are still built largely on the behavior of gases and liquids.
