JonathanG. H. Stathakis; Jake A. Cravino; Ross Andrew Shalliker – Journal of Chemical Education, 2023
In today's global economy, the origin of the food we eat is becoming more and more difficult to identify. Verifying the authenticity of products to protect supply chains is a complicated problem that requires a multidisciplinary approach. Chemical authentication of foodstuffs often includes a mass spectrometer detector; however, they are costly…

Daniel L. Silverio; Matthew J. Mistretta; Scott P. Buzzolani – Journal of Chemical Education, 2023
Offering an advanced organic chemistry course at a primarily undergraduate institution poses a challenge of condensing graduate organic synthesis into one course. This course was designed so students choose and read recent total synthesis papers from the literature in lieu of relying on a textbook or other pre-existing course materials. Following…

Kelli S. Khuong; Fabio Agnelli; Matthew A. Parker – Journal of Chemical Education, 2023
S[subscript N]2 reactions are of fundamental importance in introductory organic chemistry courses, and a number of experiments suitable for the first-semester undergraduate organic lab have been previously reported. Most of these experiments have used alkyl halides as electrophiles, but alkyl halides are often less than ideal for reasons of…

Liping Li; Tong He – Journal of Chemical Education, 2023
Learning in chemistry laboratories has long been challenging due to the complex nature of the learning environment and tasks that students engage with. Therefore, it is important to develop useful tools for prelab and follow-up activities besides the hands-on lab time for better management of the learners' cognitive load. In this paper, we…

Lauren I. Austen; Thomas I. J. Dugmore; Avtar S. Matharu; Glenn A. Hurst – Journal of Chemical Education, 2023
A laboratory experiment was designed to provide students with an introduction to byproduct valorization by producing an analogue of biodiesel (fatty acid ethyl esters, FAEE) via lipid extraction and subsequent transesterification from spent coffee grounds (SCG). Valorization is the process of upgrading underutilized or discarded wastes or…

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…

Ying Guo; Daniel Lee – Journal of Chemical Education, 2023
Learning management systems play a crucial role in addressing pedagogical challenges imposed by the COVID-19 pandemic. The solutions provided by the learning management systems (LMS) facilitated online instructions and helped form a community of learning and support. With the rapid increased usage during the pandemic and the return to face-to-face…

Ana Sofi´a Varela; Alfonso Garci´a-Ma´rquez – Journal of Chemical Education, 2023
This laboratory experiment consists of the synthesis of two series of alkaline-earth titanates (calcium-strontium and strontium-barium)to corroborate Vegard's law by obtaining their X-ray diffraction patterns and plotting the lattice parameter versus mole fraction of both cations. This experiment allows students to understand the key concepts in…

Ping Y. Furlan; Ethan J. Jaravata; Alexander Y. Furlan; Peter Kahl – Journal of Chemical Education, 2023
Corrosion of metal, especially iron, is a natural electrochemical process that costs billions of dollars every year. Educating college and precollege students, our future STEM professionals, about the chemistry that governs corrosion and its prevention strategies is of paramount importance. In this manuscript, we share a few simple iron…
