Bruun, E.; Nielsen, I. – European Journal of Engineering Education, 2010
Nanotechnology is having an increasing impact on university curricula in electrical engineering and in physics. Major influencers affecting developments in university programmes related to nanoelectronics are discussed and a model for university programme development is described. The model takes into account that nanotechnology affects not only…

Lewis, Scott E.; Shaw, Janet L.; Freeman, Kathryn A. – Journal of College Science Teaching, 2010
Creative exercises (CEs) are a form of assessment in which students are given a prompt and asked to write down as many distinct, correct, and relevant facts about the prompt as they can. Students receive credit for each fact that they include that is related to the prompt and distinct from the other facts they list. With CEs, students have an…

Soukupova, Jana; Kvitek, Libor; Kratochvilova, Martina; Panacek, Ales; Prucek, Robert; Zboril, Radek – Journal of Chemical Education, 2010
Nanoscience and nanotechnology currently represent one of the most rapidly developing fields of science and technology; therefore, the fundamental principles of nanoscience and nanotechnology should be understood by college and even high school students as well as by members of scientific communities. Silver, as the pioneer material in these…

Hirayama, Satoshi; Steer, Ronald P. – Journal of Chemical Education, 2010
The near-UV spectrum of benzene is used to illustrate the effects of variations in instrument spectral bandwidth on absorbance and molar absorptivity measurements and on the independence of values of quantities such as the oscillator strength that are based on integrated absorptivity. Excel-based computer simulations are provided that help develop…

Bellamy, Michael K. – Journal of Chemical Education, 2010
The internal standard method is widely applied in quantitative analyses. However, most analytical chemistry textbooks either omit this topic or only provide examples of a single-point internal standardization. An experiment designed to teach students how to prepare an internal standard calibration curve is described. The experiment is a modified…

Waner, Mark J. – Journal of Chemical Education, 2010
This work examines commonly used particulate-level pictures meant to illustrate gases. These pictures are found throughout textbooks in the middle grades through the college level, as well as in questions frequently used to assess conceptual learning in students. This work uses the kinetic-molecular theory of gases to demonstrate the inaccuracies…

Pinhas, Allan R. – Journal of Chemical Education, 2010
Alcohol-based hand-rub sanitizers are the types of products that hospital professionals use very often. These sanitizers can be classified into two major groups: those that contain a large quantity of thickener, and thus are a gel, and those that contain a small quantity of thickener, and thus remain a liquid. In an effort to create a laboratory…

Pappenfus, Ted M.; Hermanson, David L.; Kohl, Stuart G.; Melby, Jacob H.; Thoma, Laura M.; Carpenter, Nancy E.; Filho, Demetrio A. da Silva; Bredas, Jean-Luc – Journal of Chemical Education, 2010
A series of experiments for undergraduate laboratory courses (e.g., organic, polymer, inorganic) have been developed. These experiments focus on understanding the regiochemistry of the conducting polymer poly(3-hexylthiophene) (P3HT). The substitution patterns in P3HTs control their conformational features, which, in turn, dictates the [pi]…

Flynn, Nick – Journal of Chemical Education, 2010
One of the major focuses of biochemistry courses is metabolic pathways. Although certain aspects of this content may require a rote approach, more applied techniques make these subject areas more interesting. This article describes the use of an assignment, "Design Your Own Disease" to teach students metabolic regulation and biosignaling…

Ciaccio, James A.; Guevara, Elena L.; Alam, Rabeka; D'agrosa, Christina D. – Journal of Chemical Education, 2010
We introduce students to dimethylsulfoxonium methylide (DMSY) epoxidation of aryl and nonconjugated aliphatic aldehydes and ketones without revealing that DMSY cyclopropanates enones by Michael-initiated ring closure (MIRC). Each student performs the reaction of DMSY with one of nine carbonyl compounds, including four enones, and then analyzes the…

Grober, S.; Vetter, M.; Eckert, B.; Jodl, H. -J. – European Journal of Physics, 2010
The Rutherford scattering experiment plays a central role in working out atomic models in physics and chemistry. Nevertheless, the experiment is rarely performed at school or in introductory physics courses at university. Therefore, we realized this experiment as a remotely controlled laboratory (RCL), i.e. the experiment is set up in reality and…

Short, Michael; Short, Anne; Vankempen, Rachel; Seymour, Michael; Burnatowska-Hledin, Maria – Biochemistry and Molecular Biology Education, 2010
Practical instruction of proteomics concepts was provided using high-performance liquid chromatography coupled with a mass selective detection system (HPLC-MS) for the analysis of simulated protein digests. The samples were prepared from selected dipeptides in order to facilitate the mass spectral identification. As part of the prelaboratory…

Wagner, John R.; Bixler, Robert D.; Carraway, Elizabeth R.; Moysey, Stephen M.; Murdoch, Lawrence R.; Schlautman, Mark R.; Warner, Richard D. – Journal of College Science Teaching, 2010
The geology program at Clemson University has instituted a new, six-semester-long undergraduate research course sequence that requires student participation in ongoing departmental research projects from their sophomore through senior years. As a part of a university-wide initiative focusing on undergraduate research, termed Creative Inquiry at…

Barbarick, K. A. – Journal of Natural Resources and Life Sciences Education, 2010
Students in introductory courses generally respond favorably to novel approaches to learning. To this end, I developed and used three crossword puzzles in spring and fall 2009 semesters in Introductory Soil Science Laboratory at Colorado State University. The first hypothesis was that crossword puzzles would improve introductory soil science…

Kirkup, Les; Pizzica, Jenny; Waite, Katrina; Srinivasan, Lakshmi – European Journal of Physics, 2010
Physics experiments for students not majoring in physics may have little meaning for those students and appear to them unconnected in any way to their majors. This affects student engagement and influences the extent to which they regard their experiences in the physics laboratory as positive. We apply a framework for the development and…
