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…

Plastic waste is a growing concern in recent years due to the massive increase in single-use plastic applications. Despite the ever-increasing amount of waste, recycling plastics is not a simple process due to difficulties in sorting, which results in significantly downgraded material properties. This hands-on lab experiment showcases the…

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…

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…

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…

Thyssen, Christoph; Johannes, Eva; Müller, Katharina; Wünn, Joachim – Biochemistry and Molecular Biology Education, 2022
The CRISPR/Cas9 system opens new horizons (M. Adli, Nat Commun, 2018) regarding genetic modifications of living organisms but also as an in vitro tool in laboratory protocols. Therefore, it boosts possibilities in research and future medical treatments. As the controversial claim of genomically edited babies by He Jiankui (Cyranoski D., Nature,…

This paper reports the quantification of Ca, Mg, and Fe as micronutrients in different vegetables (spinach, sugar beets, and carrots) from raw and processed samples. Simple extraction procedures, titrations, and spectrophotometric analysis were used to determine the amounts of micronutrients before and after cooking. From the obtained results, an…

This report describes a laboratory experiment for an undergraduate-level inorganic chemistry or biochemistry course involving the study of the kinetics of the catecholase activity of a synthetic nickel(II)-oximate complex. A model substrate, 3,5-di-tert-butylcatechol(DBC), undergoes aerobic oxidation to 3,5-di-tert-butylbenzoquinone (DBQ) in the…

Teaching chemistry without access to a traditional laboratory space is an ongoing challenge that has become especially relevant because of the SARS-CoV-2 pandemic. While several remote learning options exist for covering general chemistry concepts (including kitchen-based experiments, online modules, and virtual reality), few options provide…

Electrochemistry plays a crucial role in our everyday lives. It allows us to power our phones and cars and allows for the real-time monitoring of blood glucose levels. While electrochemistry is of vital importance and is a long-established field of chemistry, it is often neglected in modern curricula for STEM courses. Herein, we show that hands-on…

Materials science research has expanded significantly in recent years; a multidisciplinary field, home to an ever-growing number of chemists. However, our general chemistry degree courses have not changed to reflect the rise in interest in this topic. In this paper, we propose a laboratory experiment for the undergraduate chemistry practical…

Physiology is an important field for students to gain a better understanding of biological mechanisms. Yet, many students often find it difficult to learn from lectures, resulting in poor retention. Here, we utilize a learning workshop model to teach students at different levels ranging from middle school to undergraduate. We specifically designed…

Whigham, Ehren; Kruse, Jerrid; Galligan, Kate – Science Teacher, 2022
The authors teach in a large, urban school district in the Midwest and typically a few students have parents who work in the sciences. One year, the authors were fortunate to have the child of the owner and head brewer of a local microbrewery. That coincidence set the stage for a major collaboration to bring the real world of chemistry and biology…

Many high school students learn about nutrient cycling during biology, environmental science, and agriculture classes. These lessons often focus on soil and plants, and nutrient cycling is usually taught independently from climate change. Scientists know that animals, including fish, can have strong effects on nutrient cycling (i.e., nitrogen and…
