Cooper, Melanie M.; Stowe, Ryan L.; Crandell, Olivia M.; Klymkowsky, Michael W. – Journal of Chemical Education, 2019
The fundamental structure of a typical mainstream two-semester organic chemistry course, populated mostly by life science majors and taught at universities throughout the United States, has changed little since the 1970s. However, much of the research on learning in organic chemistry has been devoted to characterizing student difficulties of…

Katselas, Anthony; Motion, Alice; O'Reilly, Chiara; Neto, Chiara – Journal of Chemical Education, 2019
An experiment which investigates the wettability of natural surfaces was developed for undergraduate students, which allows them to explore concepts of surface structure, wettability, superhydrophobic surfaces, and self-cleaning. The students choose their own samples of leaves and flowers present in their local environment, examine their surface…

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…

Vergne, Matthew J.; Simmons, Joshua D.; Bowen, Ryan S. – Journal of Chemical Education, 2019
An escape-room-game activity was introduced to foster team building and collaborative learning in a laboratory-experiment setting. The students were placed in a laboratory with clues and puzzles that required the students to use a sequence of analytical instruments in the laboratory in order to escape. The instruments utilized included a UV-vis…

Lenzer, Stefanie; Smarsly, Bernd; Graulich, Nicole – Journal of Chemical Education, 2019
Acquiring a basic understanding about the composition of crystal structures and the resulting structure-property relationship is central for chemists and material chemists, enabling the prediction of desired properties and the solution of a wide range of current challenges in sciences, e.g., the development of clean-energy storage. For a deeper…

Dounay, Amy B.; O'Donnell, Martin J.; Samaritoni, J. Geno; Popiolek, Lukasz; Schirch, Douglas; Biernasiuk, Anna; Malm, Anna; Lamb, Isaac W.; Mudrack, Kristen; Rivera, Daniel G.; Ojeda, Gerardo M.; Scott, William L. – Journal of Chemical Education, 2019
An experiment for the synthesis of N-acyl derivatives of natural amino acids has been developed as part of the Distributed Drug Discovery (D3) program. Students use solid-phase synthesis techniques to complete a three-step, combinatorial synthesis of six products, which are analyzed using LC-MS and NMR spectroscopy. This protocol is suitable for…

Stephens, Lisa I.; Mauzeroll, Janine – Journal of Chemical Education, 2019
One of the unique advantages of electrochemistry is that the relationship between thermodynamics and kinetics is quantitative, which is the basis of voltammetry. Mathematical models of electrochemical systems take advantage of this relationship to predict the effect of changing a system property (e.g., concentration, scan rate, or rate constant)…

Domenico, Janna; Schneider, Alexis M.; Sohlberg, Karl – Journal of Chemical Education, 2019
In this work, two exercises are described that are designed to teach students about the evolution and behavior of the electronic bands of graphene and bilayer graphene. These exercises involve performing extended Hückel molecular orbital theory calculations on polyacenes and polycyclic aromatic hydrocarbons. In the first exercise, students…

Beck, Rachel C.; Erdmann, Mitzy A. – Journal of Chemical Education, 2018
Identification and quantification of an unknown illicit drug (cocaine) from both simulated drug paraphernalia and simulated urine can be achieved via direct analysis in real time (DART) triple quadrupole linear ion trap (QTRAP) mass spectrometry (MS). We describe a novel, hands-on laboratory activity which utilizes the recent DART technology…

Vera, Fernando Luna; Chalapud, Marcelo Guancha; Viveros, Ingrid Castillo; Medina, Edgar Alexander Vasquez – Journal of Chemical Education, 2018
In this paper, we report an experiment intended as a tool to introduce chemistry and materials science students to several chemical concepts through the determination of the best experimental conditions for the formation of calcium oxide (lime) from a source of high content of calcium carbonate (eggshells). Thermal gravimetric analysis (TGA),…

Alcantara-Garcia, Jocelyn; Ploeger, Rebecca – Journal of Chemical Education, 2018
Polymers are present in most organic materials in the field of cultural heritage science and art conservation. This makes the study of polymer chemistry necessary in art conservation graduate training programs. Given each program approaches this important topic in different ways, the present paper describes areas of common ground and problems we,…
