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.

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. Stelick, Scott J.; Alger, William H.; Laufer, Jesse S.; Waldron, Anna M.; Batt, Carl A. J. Chem.

Mass Relationships in a Chemical Reaction: Incorporating Additional Graphing Exercises into the Introductory Chemistry Laboratory Stephen DeMeo The purpose of this article is to increase student involvement with graph construction specifically in the context of introductory laboratory activities that involve mass relationships between reacting substances and products. In this regard, five massmass plots derived from a synthesis of a binary compound from its elements are presented as well as a set of questions to focus learners on the significance of each plot. The benefit of providing learners with these types of graphing activities include the use of higher-order cognitive processes as well as the elucidation of fundamental chemical knowledge such as the law of the conservation of mass, the law of constant composition, limiting and excess reactants, and empirical formula.

Our Everyday Cup of Coffee: The Chemistry behind Its Magic Marino Petracco Coffee beverages are so popular all over the world that there is hardly any need to describe them. But underlying this seemingly commonplace beverage there is a whole realm worth serious scientific study. The complexity of the raw seed matrix, made even more intricate when roasted, requires a deep understanding of its chemical nature. While coffee is not consumed for nutritional purposes, it is appreciated for its taste appeal along with its stimulating effects on mental and physical activity. The attention to quality is of paramount importance to both of these aspects to supply the customers with a pleasant and wholesome product. Petracco, Marino. J. Chem. Educ. 2005, 82, 1161.

Kinetics of Alcohol Dehydrogenase-Catalyzed Oxidation of Ethanol Followed by Visible Spectroscopy Kestutis Bendinskas, Christopher DiJiacomo, Allison Krill, and Ed Vitz A two-week biochemistry experiment was introduced in the second-semester general chemistry laboratory to study the oxidation of ethanol in vitro in the presence of the enzyme alcohol dehydrogenase (ADH). This reaction should pique student interest because the same reaction also occurs in human bodies when alcoholic drinks are consumed. Procedures were developed to follow the biochemical reaction by visible spectroscopy and to avoid specialized equipment. The effect of substrate concentration on the rate of this enzymatic reaction was investigated during the first week. The effects of temperature, pH, the specificity of the enzyme to several substrates, and the enzyme's inhibition by heavy metals were explored during the second week.

A small sample of each brand of stain remover is decomposed and then analyzed. The observed difference in mass allows students to accurately determine the percentages of each component of the stain remover. A back-titration experiment and a precipitation reaction are performed to confirm the complete decomposition of the original mixture. Bracken, Jeffrey D.; Tietz, David. J. Chem. Educ. 2005, 82, 762.

A Methane Balloon Inflation Chamber Curtis J. Czerwinski and Tanya J.

As a solution to this problem, a methane balloon inflation chamber, prepared from a translucent 3.5-gallon pail and an aspirator or house-vacuum, provides an inexpensive and convenient method for inflating balloons in laboratories or lecture halls. Prepared in this way, methane-filled balloons can be used to demonstrate the effects of vacuum, the lifting power of low-density gases, and the explosive combustion of methane.

Using only a Bunsen burner, a porcelain crucible, and a charcoal briquette, the experiment demonstrates two steps in the ancient processing of copper ore: roasting and reduction. The product is a shiny copper metal bead that can then be hammered, polished, and shown to be electrically conductive. Yee, Gordon T.; Eddleton, Jeannine E.; Johnson, Cris E. J. Chem.

A gas chromatograph-mass spectrometer is used to analyze these samples, and the relative quantities of nitrogen, oxygen, carbon dioxide, water, and argon are calculated. On the basis of the data, the hypothesized sample composition is validated. Persinger, Jared D.; Hoops, Geoffrey C.; Samide, Michael J. J. Chem. Educ. 2004, 81, 1169.

Consumer Views on Chemical Additives: Are They Natural or Synthetic? A Non-Laboratory-Based Project A. S. Cotterill, D. N. John, and Y. S. Teh Results of a study demonstrate that consumers are not well informed about identifying natural products but do recognize names to which they have been exposed. Consumers also appreciate that natural compounds can come from a variety of sources and can be synthesized, and that a natural substance is not necessarily good for you or better than a synthetic substance. However, despite this knowledge, consumers do prefer products that contain natural or natural-sounding additives. Cotterill, Ann S.; John, D. N.; Teh, Y. S. J. Chem. Educ. 2000, 77, 1307.

Let's Talk about It! Using a Graded Discussion Procedure to Make Chemistry Real Amy Roediger Graded classroom discussions are a technique employed to extend students' classroom knowledge into real life. Students read a set of articles about a topic relating to the curriculum. The teacher poses an open-ended question to which the students propose answers based on the articles they read. Simultaneously, the responses are graded by the teacher, who does not participate in the discussion. Roediger, Amy. J. Chem. Educ. 2000, 77, 1305.
