Metal-organic frameworks (MOFs) are porous materials composed of metal ions and organic ligands. These materials have garnered significant attention due to their wide-ranging applications, such as the capture of hazardous molecules, catalysis, production of value-added compounds, and detection of ions or molecules in water. Despite their immense…

Removing the pollutants from various wastewater is crucial to the environment, ecology, and humans. However, the pollutants are generally removed by chemical decomposition, which not only consumes a lot of energy but also produces carbon emissions. Electrochemical flocculation is effective to extract pollutant molecules and heavy ions from…

Alexandra Taraboletti – Journal of Chemical Education, 2024
In response to the shifting modalities of laboratory-based education, particularly amidst the rise of virtual and at-home instruction, we introduce a novel hybrid laboratory module for undergraduate biochemistry and biology courses. Central to this innovative approach is the use of sourdough as a versatile and accessible model organism, enabling a…

Stanga, John P.; Nash, Troy R.; Pannell, Megan D. – American Biology Teacher, 2023
Concepts relating to enzymes and energy are central to understanding chemical and biological processes at the molecular level. Student learning of these crosscutting concepts can be challenging, so it is important to identify misconceptions and remediate them early, especially in introductory classes. Here we describe an activity in which…

Hans Eric Muehsler – European Journal of Physics Education, 2023
Lab activities are a vital part of physics courses, providing students with hands-on experiences of classroom topics. At the same time, building self-efficacy is vital to student learning and retention; however, females traditionally have lower self-efficacy in STEM fields. This research explores the role of gender and the changes in interest in…

In this paper, we present a concise and technique-heavy route to the synthesis of dimedone for a second-year organic chemistry curriculum. Our preparation of dimedone guides students through a Michael addition followed by a Dieckmann cyclization, basic ester hydrolysis, and thermal decarboxylation, while allowing time for mechanistic discussion…

Arun Richard Chandrasekaran – Journal of Chemical Education, 2023
The field of DNA nanotechnology has grown rapidly in the past decade and has expanded to multiple laboratories. While lectures in DNA nanotechnology have been introduced in some institutions, laboratory components at the undergraduate level are still lacking. Undergraduate students predominantly learn about DNA nanotechnology through their…

Providing hands-on practical education without access to laboratories during the COVID-19 pandemic has required creativity and innovation. In this paper, co-authored by academic staff and students, we describe an at-home mobile phone-based 'spectrophotometer' experiment used in an introductory undergraduate biology course. Using colour picker…
