Petty, Anthony J., II; Odom, Susan A. – Journal of Chemical Education, 2021
An operationally simple, reliable synthesis of ethynylated acenes suitable for an upper-division undergraduate organic chemistry laboratory course has been developed. This experiment requires students to synthesize two acene derivatives and can be completed in 6-8 laboratory sessions (3 h each); a shorter experiment could be realized in the…

Funicello, Maria; Cerminara, Iole; Chiummiento, Lucia; Lupattelli, Paolo; Felluga, Fulvia; Berti, Federico – Journal of Chemical Education, 2021
Multicomponent reactions (MCRs) represent very interesting tools to reach eco-friendly and sustainable transformations in organic chemistry. In particular, the Biginelli reaction furnishes a very easy approach to the synthesis of a library of biological active compounds in an academic course. Here we describe the realization of several experiments…

Savakinas, Mallory V.; Frey, Olivia M.; Piro, Nicholas A.; Rhile, Ian J.; Hamann, Christian S. – Journal of Chemical Education, 2021
Friedel-Crafts alkylation reactions using a curated set of alcohols provide students with the opportunity to combine the study of electrophilic aromatic substitution with carbocation rearrangements. In this experiment students may be presented with up to nine alcohols that yield six products, all synthesized under identical reaction conditions.…

Dieguez, Gisselle; Karpenkopf, Jonathan; Labrador, Aaron; Gimenez, Ludmila; Guerra, Julian; Fulton, Jack; Walecki, Wojciech J. – Physics Teacher, 2021
Although ripple tanks have been used in the past to perform wave simulations for electromagnetic and acoustic phenomena, especially before the advent of computers, they are still often used to demonstrate wave propagation in high school and college physics classrooms. Usually ripple tanks have a rectangular shape. The wave propagating through the…

Sedunov, Boris – International Society for Technology, Education, and Science, 2021
Thermodynamics education is not easy both for students and teachers. But the Entropy, Chemical potential, Real gas structure, Fugacity, Molecular interaction, Supercritical phenomena chapters become more comprehensible, if introduced via the pure real gases' cluster physics chapter. A pure gas consists of the only one type of basic particles,…

Cai, Longfei; Zhang, Xiaolin; Luo, Liquan; Lin, Huibin; Chen, Jinhua; Xu, Chunxiu; Zhong, Minghua; Liao, Xiaoning – Journal of Chemical Education, 2019
We described a simple method for detection of Fe on a thread-based analytical device. Fe reacts with 1,10-phenanthroline to form a colored band on a cotton thread; the length was measured to quantify the contents of Fe using a ruler. This method has the advantages of easy operation, low cost, easy fabrication, and reduced sample/reagent…

Mangis, J. W.; Mansur, T. B.; Kern, K. M.; Schroeder, J. R. – Bioscene: Journal of College Biology Teaching, 2019
Undergraduate research is a valuable tool to demonstrate both the dedication and time required to be a successful biologist. One area of research that has intrigued students over the last several years is cytotoxicity. However, at smaller undergraduate institutions, the time, training, and funding available for these research studies may be…

Monga, Vishakha; Knox, Kerry J.; Gillis, Elizabeth A. L.; Stoodley, Robin; Bussiere, Guillaume; Rogers, Christine – Journal of Chemical Education, 2019
The implementation of an integrated approach to upper-level undergraduate chemistry laboratory instruction that incorporates student choice both in the selection and sequencing of the experimental work is presented. The approach involves combining laboratory work in several traditional subdisciplinary areas of chemistry in a single course.…

Mancheño, María José; Royuela, Sergio; de la Peña, A.; Ramos, Mar; Zamora, Félix; Segura, José L. – Journal of Chemical Education, 2019
In order to introduce the concept of covalent organic frameworks (COFs), an important class of predictable crystalline porous polymers, an integrated laboratory experiment for advanced organic chemistry students is reported. The importance of these kind of polymers and their multiple applications are presented as a part of key concepts in polymer…

Overly, Kenneth R. – Journal of Chemical Education, 2019
An experiment for the undergraduate organic chemistry laboratory involving a method for the isolation of eugenol from cloves has been developed. The experiment employs microwave-assisted extraction (MAE) of the essential oil from whole cloves using aqueous ethanol and the subsequent isolation of eugenol by acid-base extraction. The MAE allows for…

Debije, Michael G. – Journal of Chemical Education, 2019
This work presents an outline for a full-quartile design-based learning laboratory-based course suitable for final year Bachelor's students. The course has been run for 5 years in the department of Chemical Engineering and Chemistry. The course attempts to provide a complete laboratory experience for its students, including an authentic research…

Miller, Daniel P.; Phillips, Adam; Ludowieg, Herbert; Swihart, Sarah; Autschbach, Jochen; Zurek, Eva – Journal of Chemical Education, 2019
A computational laboratory experiment investigating molecular models for hexagonal boron-carbon-nitrogen sheets (h-BCN) was developed and employed in an upper-level undergraduate chemistry course. Students used the Avogadro user interface for molecular editing and the WebMO interface for the quantum computational workflow. Density functional…

Harris, C.; Gaster, C.; Gelabert, M. C. – Journal of Chemical Education, 2019
Synthesis and characterization of nanomaterials yields opportunities for instruction of related topics in solution chemistry and materials science, as well as spectroscopy connecting to band theory, the "particle in a box" quantum mechanical model, and thermodynamics. In collaboration with an undergraduate research assistant, we have…

Adams-McNichol, Anna L.; Shiell, Rayf C.; Ellis, David A. – Journal of Chemical Education, 2019
Student-built photometers are recognized as being useful tools in teaching laboratories that help students understand the concepts behind experimental measurements, and several devices have been reported that employ photoresistors as the detector of choice. We demonstrate here an improvement over these instruments and the analyses thereof,…

David P. Reid; Timothy D. Drysdale – IEEE Transactions on Learning Technologies, 2024
The designs of many student-facing learning analytics (SFLA) dashboards are insufficiently informed by educational research and lack rigorous evaluation in authentic learning contexts, including during remote laboratory practical work. In this article, we present and evaluate an SFLA dashboard designed using the principles of formative assessment…
