In this brief experiment, students create a superhydrophobic surface as an application of polar--nonpolar interactions and redox chemistry. Half of a zincgalvanized steel strip is coated in copper nanoparticles through electroless deposition. A layer of nonpolar octadecanethiol is added to half of that copper surface. Students classify the three…

Glasscott, Matthew W.; Verber, Matthew D.; Hall, Jackson R.; Pendergast, Andrew D.; McKinney, Collin J.; Dick, Jeffrey E. – Journal of Chemical Education, 2020
Experimental electrochemistry offers unique opportunities for interactive instruction at all levels of education; however, widespread adoption in curricula is hindered by high costs associated with electrochemical instrumentation. Thus, the development of affordable instruments represents an essential step toward making electrochemistry accessible…

A laboratory activity is described for senior high school or first year undergraduate level students that illustrates key concepts linked to extractive metallurgy. This experiment demonstrates preferential binding of a methoxyphenolic oxime ligand to Cu[superscript 2+] in the presence of other transition metal ions in aqueous solution. The…

Rojas, Roberto – Physics Teacher, 2022
In one of the Faraday's experiments an electric current is induced in a conducting loop when a magnet in front of it moves towards or away from the loop. While the direction of circulation of the electric current in the loop has only two options, it depends on three experimental conditions that generate eight cases. Even though the Faraday law or…

An undergraduate laboratory was developed as part of the Drugs for Neglected Diseases "initiative's" Open Synthesis Network. This activity aimed to develop new compounds efficacious against visceral leishmaniasis. Students successfully synthesized, purified, and characterized ten different benzoxazole amides that were sent for biological…

Oss, Stefano – Physics Education, 2022
We propose an experiment in which the sound of a drumroll is recorded and analysed according to a simple mechanical model in which the inelastic restitution coefficient of the collision between the stick and drum surface, as well as the ongoing kinematics of the drumstick, are considered. The agreement shows that this model is well suited for…

Manninen, Marianna; Vesterinen, Veli-Matti; Vainio, Anna-Kaisa; Korhonen, Heidi; Karonen, Maarit; Salminen, Juha-Pekka – Journal of Chemical Education, 2021
Plants encounter several different threats that affect their well-being during the spring. With chemistry, plants may defend themselves from, for example, excess UV-radiation and herbivores. The defense compounds between plant species vary, which makes it possible to utilize chemistry in identifying the plant species. In this laboratory…

Konkankit, Chilaluck C.; Marker, Sierra C.; Bigham, Nicholas P.; Dale, Darren S.; Zax, David B.; Lorey, Daniel R., II; Wilson, Justin J. – Journal of Chemical Education, 2021
There currently exists a significant deficiency in the nuclear chemistry workforce within the United States, despite its importance in areas of medicine, national security, and energy. Poor coverage of this topic across many chemistry departments at the undergraduate level likely contributes to this shortage. Increasing interest and hands-on…

The American Chemical Society advocates a shift from rule-based to risk-based safety education for chemistry graduates, emphasizing meaningful student engagement in the risk assessment process for laboratory work. To implement this paradigm shift, we introduced RAMP (Recognize Hazards, Assess Risk, Minimize Risk, and Prevent Emergencies)-based…

As simple and ubiquitous redox-active organic molecules, quinones participate in diverse electron transfer processes in chemistry and biological systems for energy transformation and signal transduction. We introduce here a practical exercise to study the redox potentials of benzoquinone and its two derivatives by combining the electrochemistry…

Traver, Emily; Stark, Jamie E.; Milán, Gianna Aleman; Andreas, Heather A. – Journal of Chemical Education, 2019
In this supplement to our second-year supercapacitor lab (Bringing Real-World Energy-Storage Research into a Second-Year Physical-Chemistry Lab Using a MnO[subscript 2]-Based Supercapacitor. "J. Chem. Educ." 2018, 95 (11), 2028-2033), we incorporate a color indicator as indirect evidence for the manganese oxide's pseudocapacitive…

Calcabrini, Mariano; Onna, Diego – Journal of Chemical Education, 2019
The study of gels and their properties is a compelling topic both technologically and scientifically, and should therefore be emphasized in chemistry and material science syllabuses. In the present laboratory experiment, we propose two experiences, aimed at introducing gelation and gel transport properties using silica gels made from sodium…

Roslan, Amira Adlin; Tayyab, Saad – Biochemistry and Molecular Biology Education, 2019
A laboratory exercise on the interaction between the herbicide pendimethalin (PM) and goat serum albumin (GSA), a carrier protein present in mammalian blood circulation, is described. Fluorescence spectroscopy was used to study the binding reaction between PM and GSA. Titration of a constant amount of the protein (GSA) with increasing ligand (PM)…

Militello, Kevin T.; Reinhardt, Josephine A. – Biochemistry and Molecular Biology Education, 2019
Next generation sequencing has revolutionized molecular biology and has provided a mechanism for rapid DNA and RNA sequence analysis. Yet, there are few resources to introduce next generation sequencing into the undergraduate biochemistry and molecular biology curriculum. Herein, we describe the design, execution, and assessment of a four-week…
