The electric field inside a uniformly charged long cylindrical shell is a standard example discussed in introductory university physics. The field is zero inside the cylinder; outside of the cylinder, the field behaves like a long wire at the center carrying the same amount of charge per unit length, analogous to that of a uniformly charged…

Cyclopropane can be hydrogenated to produce propane under moderately high temperatures ([tilde]175 [degrees]C). Using a nanoparticle palladium catalyst, undergraduate students can explore the reaction and draw conclusions regarding the conditions for reaction. When deuterium is used, conclusions pertaining to the reaction mechanism are possible.…

Here, we present a laboratory activity in which the students work on an analysis of a questioned document that was written with one out of five possible pens. As a forensics study, the activity applied chemistry and analytical chemistry tools to solve the case. The students were able to apply polarity and solubility concepts to select and discard…

Adams, William; Sonntag, Matthew D. – Journal of Chemical Education, 2022
Electrophilic aromatic substitution (EAS) represents an important class of reactions taught in the undergraduate organic chemistry curriculum. The EAS reaction of benzene and its substituted derivatives is generally described as proceeding through a carbocation (arenium cation) intermediate, and the regiochemistry of the product is heavily…

Carroll, David J. – Biochemistry and Molecular Biology Education, 2022
Students often have no exposure to the incredible amount of genomic and proteomic data that is freely and easily accessible online. Becoming familiar with these resources, and seeing how they could be applied to a specific research question, is a prerequisite for students to apply them to their own scientific development. Many students have to…

Dai, Rucheng; Wang, Zhongping; Zhang, Zengming; Sun, Lazhen – Physics Teacher, 2022
In this paper, an experimental setup composed of a color-mixing device, power supply, and spectrometer is developed. This setup is available for students to do hands-on color mixing with red, green, and blue light in undergraduate labs. LED volt-ampere and spectrum characteristics are investigated. The apparatus was used to perform additive color…

The COVID-19 pandemic affected a large range of in-person education activities in Colombia. This created great limitations in academic performance for students with reduced access to communication technologies and deepened the educational gaps in the country. This was particularly true for sciences such as biochemistry. In Colombia, molecular…

Heterocyclic compounds are an integral part of research, particularly in the pharmaceutical field. The synthesis of such compounds in an undergraduate laboratory can help students understand the relevance and importance of their field of study. Our experimental activity introduces a novel procedure to synthesize coumarin, a heterocyclic formed by…

An active-learning approach was employed in a project for our chemistry major students on the synthesis of biodiesel (BD) from an Amazon region oil. The project, involving activities in class and in the laboratory, was given during 8 weeks of the spring semester of 2022. The students were asked about their previous contact with the synthesis and…

Jessica K. Kisunzu – Journal of Chemical Education, 2023
Discussions of the primary literature are an important part of undergraduate education, and much work has been done to develop methods of integrating the literature into the curriculum. Examples include individual single-article discussion activities, literature-based courses, and regular journal club events. While many published examples focus on…

Enzymes, enzymatic kinetics, and enzyme inhibition are topics covered in undergraduate biochemistry textbooks, having perceptible relevance to everyday life. The experimental use of enzymes involved in basic physiologic processes may be of utmost pedagogic interest because they bring evidence on how a significant number of drugs are used to…

Kantor, Andrew G.; Scherr, Thomas Foster; Wright, David W.; Verberne-Sutton, Susan Denise – Journal of Chemical Education, 2022
Lateral flow assays (LFAs) have been used extensively for diagnosis of various diseases and conditions because they are inexpensive, rapid, robust, and easy to use. Incorporating LFAs into undergraduate chemistry courses could enrich the curricula by providing the students with a real-world application of analytical chemistry concepts,…

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…
