Joss, Lisa; Müller, Erich A. – Journal of Chemical Education, 2019
Recent advances in computer hardware and algorithms are spawning an explosive growth in the use of computer-based systems aimed at analyzing and ultimately correlating large amounts of experimental and synthetic data. As these machine learning tools become more widespread, it is becoming imperative that scientists and researchers become familiar…

Hill, David J.; Williams, Olivia F.; Mizzy, Danianne P.; Triumph, Therese F.; Brennan, Catherine R.; Mason, Dawn C.; Lawrence, David S. – Journal of Chemical Education, 2019
A laboratory-safety course has been developed that is designed to introduce first-year graduate students to the array of dangers associated with research in the chemical sciences. We describe the challenges of creating an impactful course that seeks to convey practical laboratory-safety information in a classroom setting for students with a…

Bokosmaty, Rena; Bridgeman, Adam; Muir, Meloni – Journal of Chemical Education, 2019
As part of curriculum renewal in three introductory chemistry courses at the University of Sydney, a partially flipped classroom model was implemented. Content that is conventionally delivered in the in-class sessions was moved online through the use of web-based tutorials, videos and quizzes. During the in-class sessions, active learning…

Parsons, Andrew F. – Journal of Chemical Education, 2019
Retrosynthetic analysis is a topic that presents significant conceptual challenges to students. To enable a more active learning of introductory retrosynthesis, we implemented a flipped approach, delivered over a 4 year period, to a class size of between 18 and 29 biochemistry students per year. This provided more time for in-class peer group…

Ward, Alexandra M.; Wyllie, Graeme R. A. – Journal of Chemical Education, 2019
We report here a second semester general chemistry laboratory project themed around chitosan-alginate bioplastics. With increasing awareness of plastic pollution in the environment and the awareness of the importance for materials which are either made from renewable resources or are biodegradable, this topic provides a relevant opportunity to…

Fernández, Gabriela A.; Ocampo, Romina A.; Costantino, Andrea R.; Dop, Néstor S. – Journal of Chemical Education, 2019
Visually impaired or blind students require adjustments to the traditional hands-on activities and methodological and didactic strategies employed by the teacher. These adaptations are based on multisensory teaching tools, which reinforce the learning of all students in general. This paper presents simple teaching resources that allow students…

Dander, Jacob E.; Morrill, Lucas A.; Nguyen, Melinda M.; Chen, Shuming; Garg, Neil K. – Journal of Chemical Education, 2019
An undergraduate organic chemistry laboratory experiment involving the breakage of amide C-N bonds is reported. Whereas amides are typically considered stable species due to well-established resonance effects, this experiment allows students to cleave the amide C-N bond in a nickel-catalyzed esterification process. Moreover, students perform the…

This work provides information about a free-of-charge, trilingual (Portuguese, Spanish, and English), game-based application. The game allows high-school and undergraduate students to review chemical nomenclature in an engaging and fun way on their own by answering random questions from a database with over 700 questions. Student testing revealed…

Limpanuparb, Taweetham; Ruchawapol, Chattarin; Sathainthammanee, Dulyarat – Journal of Chemical Education, 2019
Quantitative demonstration of chemical kinetics often requires sophisticated equipment and materials. By using inexpensive and commonly available chemicals, we propose here two clock reactions, oxygen-safranin-benzoin clock and cysteine-iodine-hydrogen peroxide clock. Students simply measure and add stock solutions to start clock reactions. Sudden…

Bouldin, Ryan M.; Folchman-Wagner, Zoë – Journal of Chemical Education, 2019
There is a need for more courses that directly address the role business plays in the development of new products and technology. This is particularly true in the areas of green and sustainable chemistry where altruism is often not enough to overcome perceived increased cost. Chemistry of Sustainable Products is an undergraduate chemistry course…

Burkett, Jeremy R.; Dwyer, Timothy M. – Journal of Chemical Education, 2019
High-impact practices, and other pedagogical advancements, have been successfully used to deepen student engagement with courses over a wide variety of disciplines. Here, we describe the design, implementation, and assessment of a cross-disciplinary, inquiry-based lab course built on the proven success of these deeply engaging principles. This new…

Wang, Sunmeng; Schipper, Derek J. – Journal of Chemical Education, 2019
The polarized optical microscope (POM) is an invaluable tool for characterizing materials such as liquid crystals and other optically anisotropic materials. Despite its frequent use in research settings, students are rarely introduced to its fundamental operation and importance. Curricula are starting to appear for applications of the POM in…

Colacino, Evelina; Dayaker, Gandrath; Morère, Alain; Frišcic, Tomislav – Journal of Chemical Education, 2019
The implementation of environmentally friendly, solvent-free mechanochemical synthesis in an undergraduate chemistry teaching laboratory is described. As a model reaction, the experiment addresses the catalytic mechanochemical synthesis of a small library of sulfonylureas, including a known active pharmaceutical ingredient, tolbutamide. The…

Vié, Clotilde; Fattaccioli, Jacques; Jacq, Philippe – Journal of Chemical Education, 2019
This activity introduces droplet-based millifluidics and the usage of aqueous droplets as independent chemical microreactors for reaction-kinetics studies. Students build their own droplet generators from common macroscopic glassware and connecting parts to create trains of millimeter-sized droplets in which a redox reaction takes place. The…

Boyce, Mary C.; Lawler, Nathan G.; Tu, Yingqi; Reinke, Stacey N. – Journal of Chemical Education, 2019
Metabolomics is the data-driven science of small molecules. Untargeted metabolomics, using liquid chromatography-high resolution mass spectrometry (LC-HRMS), differs greatly from targeted metabolite assays, using nominal mass LC-MS instruments, as it generates thousands of metabolite features which are not quantified and are identified "post…
