Electrochemistry represents a powerful sustainable method for chemical synthesis; however, its widespread application is limited due to the lack of exposure and appropriate basic training of synthetic chemists and engineers in electrochemistry and electrochemical engineering. The introduction of diverse laboratory practices to the current…

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 view of the mounting requirements for courses in nuclear chemistry and radiochemistry, hands-on experience in the separations of radioisotopes is imperative. Three separation techniques commonly used were introduced, coprecipitation, liquid-liquid extraction, and ion-exchange chromatography. Their principles and the associated fundamental…

Successful demonstration of lipid assembly chemistry to a general audience can be challenging on both physical (nanoscopic dimensions of lipid assemblies) and intellectual (complex, interconnected concepts) accounts. Quite often, an instructor has to leave key concepts out of what is being offered due to time constraints, which unfortunately…

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…

Already when they enter primary school, children have rich everyday experience with factors influencing the rate of liquids' evaporation. Tea spilled into a large puddle on the table evaporates more rapidly than the same amount remaining in the cup, laundry hanging on a clothesline dries faster on a hot and windy day in comparison with a cold and…

Over 200 years ago, Alessandro Volta published his observations of a steady voltage when a piece of electrolyte-soaked cardboard was sandwiched between two dissimilar metals. This observation initiated a century of argument as to the origin of voltaic electricity (contact vs chemical) and catalyzed practical advances, such as the first…

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…

The autumnal leaf color change is a familiar phenomenon to most students living in temperate climate zones. The extraction and analysis of the pigments of the autumn leaves provide an engaging way to study the phenomenon utilizing both simple as well as more sophisticated analytical methods. In this laboratory experiment, students extract the red…

We describe here a 4 hour experimental session based on reaction monitoring of the degradation of an organic pollutant via a Fenton-like reaction. An aqueous solution of p-nitrophenol is treated with hydrogen peroxide and magnetite, and the progress of the reaction is monitored by UV-vis spectrophotometry and/or gas chromatography using an…

Introductory organic chemistry laboratory is often a difficult course for students in terms of translating the structural information and reactivity learned in lecture to the practical applications found in the laboratory. These concepts are even more difficult when presented through distance learning when a student cannot get hands-on experience.…

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…

A science camp for blind or visually impaired (BVI) students, covering mainly hands-on chemistry experiments, is described. The scientific experiments are detailed, and the feedback of the students is recorded, highlighting the benefits of the camp and its impact. BVI students actively participated in conducting the scientific experiments using…

A flash purification system using prepacked cartridges containing different silica weights and particle sizes was employed to demonstrate the influence of column characteristics on chromatographic resolution. This chromatographic experiment was a helpful introduction to chromatographic courses where the influence of particle sizes was addressed…
