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…

Hydrogels are soft water-rich materials with physical properties that can be easily tuned by modifying their network structure. For instance, increasing or decreasing the cross-linking density has a profound effect on their water absorption capabilities and mechanical strength. These physical changes are showcased in a new experiment for organic…

A. M. Ranjika P. Bopegedera – Journal of Chemical Education, 2023
Calorimetry is a central concept in the first semester general chemistry curriculum, and constant pressure (coffee-cup) calorimetry is a common experiment in the laboratory. However, constant volume (bomb) calorimetry is traditionally reserved for the physical chemistry laboratory. This article describes the advantages of incorporating bomb…

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…

As e-commerce increases, the demand for packaging materials and the potential for generating waste and negative environmental impacts also rise. Packing peanuts are a type of plastic packaging material that are used to protect goods during the shipping process. Petroleum-based plastics are common packaging materials due to their low cost, light…

Leri, Alessandra C.; Pavia, Ashley P. – Journal of Chemical Education, 2022
This experiment introduces undergraduate organic chemistry students to analysis and interpretation of Fourier transform infrared (FTIR) spectra through characterization of postconsumer plastics. Students use FTIR spectra to identify and differentiate the common recyclable polymer resins #1-6: polyethylene terephthalate (PETE), polyethylene (HDPE…

Early research experiences play an important role in shaping students' academic and professional development and future career path. While many colleges and universities offer undergraduate students the chance to engage in research, a significant number of high school students face limited or no access to such opportunities. Initiatives such as…

Antonio Va´zquez-Lo´pez; Joaqui´n Artigas-Arnaudas; Javier Bedmar – Journal of Chemical Education, 2024
Herein we propose the implementation of an "escape room" activity to reinforce chemistry-related concepts for students of the Bachelor of Arts and Fashion. In this work, a combined online and offline activity is developed, easily adaptable to different environments. The online activity consists of 5 blocks of multiple-quiz questions…

Polymer chemistry is an important subject in the undergraduate chemistry curriculum. It is required for ACS-certified degrees and significantly connects to real world issues like the plastic waste crisis. While some concepts of polymer chemistry can be incorporated into lecture courses, students' understanding of material properties and…

Houben, Sofie; Quintens, Greg; Pitet, Louis M. – Journal of Chemical Education, 2020
Polymer materials are indispensable in our daily lives. This makes polymer technology of critical importance in higher education. In particular, hands-on experiment-based practicals/laboratories with a focus on polymer science are of tremendous value in the undergraduate curriculum. Along these lines, hydrogels are highly cross-linked polymer…

Cortés, María T.; Vargas, Christian; Blanco, Diego A.; Quinchanegua, Ingrid D.; Cortés, Cristian; Jaramillo, Andres M. – Journal of Chemical Education, 2019
The bioinspired polymer polydopamine is synthesized and deposited on semiconductive glass substrates under different synthesis conditions (pH and oxidant type). Electrochemical methods are used to verify polymer deposition on the substrate and to examine the charge transfer properties of the obtained coatings. The presence of aromatic rings from…
