Jacob S. Hirschi; Dayana Bashirova; Tim J. Zuehlsdorff – Journal of Chemical Education, 2023
Density functional theory (DFT) is indubitably the most popular and among the most successful approaches for approximately solving the many-electron Schro¨dinger equation. The level of understanding on the part of both researchers and students using DFT, however, is lacking, given the availability of black-box software. The present work addresses…

Michael E. Robbins; Gabriel J. DiQuattro; Eric W. Burkholder – Physical Review Physics Education Research, 2025
[This paper is part of the Focused Collection in Investigating and Improving Quantum Education through Research.] One of the greatest weaknesses of physics education research is the paucity of research on graduate education. While there are a growing number of investigations of graduate student degree progress and admissions, there are very few…

Espinasse, Adeline; Jayaraman, Ashish; Reisbick, Spencer A.; Harris, Celina M.; Kou, Yangming; Xu, Hongyun; Anderson, Constance B.; Bader, Taysir K.; Sitek, Anna A. – Journal of Chemical Education, 2021
The Joint Safety Team (JST) was conceived in 2012 by the Departments of Chemical Engineering and Materials Science and Chemistry at the University of Minnesota and the Dow Chemical Company as a model student-led safety organization. The JST initiative was aimed at improving academic safety through four core areas: compliance, awareness, resources,…

Mayta, Martín L.; Dotto, Marcela; Orellano, Elena G.; Krapp, Adriana R. – Biochemistry and Molecular Biology Education, 2022
The CRISPR/Cas9 system is widely used for editing genes in various organisms and is a very useful tool due to its versatility, simplicity, and efficiency. To teach its principles to post-graduate students we designed a laboratory activity to obtain and analyze PDS3 mutants in "Arabidopsis thaliana" plants consisting of: 1) Design of…

Navarro, Yolanda; Soengas, Raquel; Iglesias, María José; Ortiz, Fernando López – Journal of Chemical Education, 2020
NMR spectroscopy is traditionally taught to students during Organic Chemistry as a tool used for the determination of structures after synthesis. However, modern NMR spectroscopy has many important applications beyond structure elucidation, including molecular profiling of complex mixtures as biofluids and food samples. In this experiment,…

Kou, Yangming; Peng, Xiayu; Dingwell, Claire E.; Reisbick, Spencer A.; Tonks, Ian A.; Sitek, Anna A. – Journal of Chemical Education, 2021
While lab accidents that involved personal injuries or significant property damage are required to be reported by law, many minor lab incidents or near misses are less frequently reported, especially in an academic research environment. However, public awareness of these stories and incidents create valuable learning opportunities and can prevent…

Jarabak, Charlotte; Mutton, Troy; Ridley, Damon D. – Journal of Chemical Education, 2020
Properties of chemical substances drive a large portion of research in the sciences, but properties are very difficult to search in full text documents, and while searches in chemical information retrieval resources may help, the effective use of such resources may require considerable knowledge of the indexing and excerption policies in the…

Piechota, Eric J.; Meyer, Gerald J. – Journal of Chemical Education, 2019
A central theme in introductory and advanced chemical education courses pertains directly to the transfer of electrons between atoms, ions, or molecules. This article presents theoretical treatments of electron transfer with specific attention toward applying these principles to experiment. The goal is to revitalize teaching electron transfer at…

The high Arctic is a remote place, where geoscientific research and teaching require expensive and logistically demanding expeditions to make use of the short field seasons. The absence of vegetation facilitates the use of modern photogrammetric techniques for the cost-effective generation of high-resolution digital outcrop models (DOMs). These…

Faraj, Santiago Enrique; Rossi, Rolando Carlos; Montes, Mónica Raquel – Journal of Biological Education, 2021
This report describes the implementation of a laboratory exercise for an advanced biochemistry or enzyme kinetics class at the undergraduate or graduate level, designed to improve understanding of protein conformational changes associated with the binding of a ligand. Students measure the fluorescence changes induced by the conformational…

Pfister, Hans – Physics Teacher, 2021
The Ball Bearing High Voltage generator is a fairly simple and transparent apparatus that can serve as a tool to motivate conceptual descriptions and calculations in electrostatics that are normally presented to our students in a rather dry and matter-of-fact fashion. For example, instead of posing a problem in the typical textbook form of…

Šarac, Bojan; Hadži, San – Journal of Chemical Education, 2021
A Microsoft Excel workbook has been developed to simplify the quantitative analysis of experimentally measured titration curves for diprotic and triprotic amino acids such as glycine, arginine, histidine, and glutamate. Students perform the titration, enter the data into the worksheet, and manually adjust the resulting pK[subscript a] values to…

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…
