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. Cortés, María T.; Moreno, Juan C. J. Chem. Educ. 2005, 82, 1372.

Procedure for Decomposing a Redox Reaction into Half-Reactions Ilie Fishtik and Ladislav H. Berka The principle of stoichiometric uniqueness provides a simple algorithm to check whether a simple redox reaction may be uniquely decomposed into half-reactions in a single way. For complex redox reactions the approach permits a complete enumeration of a finite and unique number of ways a redox reaction may be decomposed into half-reactions. Several examples are given.

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.

A Simple Experiment for Ion Migration Karl E. Bessler and Daniel de Oliveira Campos A simple, versatile, and low-cost version of a qualitative ion migration experiment is presented, which needs a minimum amount of chemicals and can be performed by inexperienced students. In the experiment cations and anions (preferably colorless or faintly colored) migrate toward one another and on combination produce insoluble and strongly colored compounds.

Student Construction of a Gel-Filled Ag/AgCl Reference Electrode for Use in a Potentiometric Titration James M. Thomas Instructions for the preparation of a Ag/AgCl "reference"-type electrode that uses a gel-type matrix are given. In addition, construction steps are provided for a very sturdy Pt-nichrome "inert" electrode, which can be used many times. Together, these two electrodes, along with a multivoltmeter, have been used successfully to determine the percent of iron in Fe(NH4)2(SO4)2 and in Fe2O2 unknowns purchased commercially.

A Closer Look at the Addition of Equations and Reactions Damon Diemente Chemists occasionally find it convenient or even necessary to express an overall reaction as the sum of two or more component reactions. A close examination, however, reveals that the resemblance between chemical algebraic equations is entirely superficial, and that the real meaning of addition in chemical equations is subtle and varies from case to case. In high-school courses, students are likely to encounter the addition of equations in thermochemistry, in electrochemistry, and in kinetics. Diemente, Damon. J. Chem. Educ. 1998, 75, 319.
