St. John, Pamela M.; Kienzle, Scott D.; Flood, Brianna M.; Moody, Troy V.; DePaola, Nicole F.; Mass, Spencer – Journal of Chemical Education, 2021
With the enormous reliance on plastics in the world today, bisphenol A, an additive used in the synthesis of many plastics, such as polycarbonate, has been found almost everywhere in our environment including in soil, in natural waters, and inside organisms including humans. A multidisciplinary experiment is presented that involves using flatworms…

Bolay, Austin L.; Hiester, William; Davis, Nicole Y.; Weiland, Mitch H. – Journal of Chemical Education, 2020
Polymers are ubiquitous and essential to modern society, which is why the American Chemical Society has mandated inclusion of polymer chemistry in the undergraduate curriculum. To meet this requirement, we have chosen to weave a polymeric theme through multiple laboratory courses beginning with organic chemistry, where students use aspartic acid…

Lisensky, George; Dauzvardis, Fabian; Luo, Jiaqi; Horger, Jacob; Koenig, Emma – Journal of Chemical Education, 2020
Polymers and nanochemistry are important facets of chemistry. In this experiment, students synthesize monodispersed poly(methyl methacrylate) nanospheres from the addition or chain polymerization of a rapidly stirred aqueous mini-emulsion of methyl methacrylate. The 2,2'-azobis(2-methylpropionamidine) dihydrochloride serves as a heat activated,…

Ani Nvehr Davis; Stephan Georgiev Michaelov; Clayton Joshua Rogers; Leighann Rose Weber; Brycelyn Marie Boardman; Gretchen Marie Peters – Journal of Chemical Education, 2022
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…

Knurr, Benjamin J.; Hauri, James F. – Journal of Chemical Education, 2020
For the past century, humans have been increasingly dependent on plastics, but have not developed adequate disposal practices. In this lab, students are asked whether burning plastic for energy seems like a reasonable disposal technique. To answer the chemical aspects of this question, students use bomb calorimetry to quantify the combustion…

Wu, Kaiting; Yu, Lin; Ding, Jiandong – Journal of Chemical Education, 2020
Biocompatible and biodegradable block copolymers composed of poly(ethylene glycol) (PEG) and aliphatic polyester are a class of promising biomaterials. Herein, a teaching experiment was designed to furnish undergraduates with a reliable method to synthesize an amphiphilic poly([epsilon]-caprolactone)-PEG-poly([epsilon]-caprolactone) (PCL-PEG-PCL)…

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…

Gormong, Ethan A.; Wentzel, Michael T.; Cao, Boen; Kundel, Laura N.; Reineke, Theresa M.; Wissinger, Jane E. – Journal of Chemical Education, 2021
Polymerization reaction media can have a profound effect on the physical properties of the resultant polymer. This phenomenon is showcased in a new experiment for the organic chemistry and polymer science teaching laboratories wherein the radical copolymerization of biobased [beta]-myrcene and dibutyl itaconate is performed using a nonhazardous…

Alford, Aaron; Caviedes, Racquel; Kharlampieva, Eugenia – Journal of Chemical Education, 2020
We developed a multipart laboratory experiment on the synthesis of free-standing hydrogels for junior to senior undergraduate students. In this experiment series that runs over the course of multiple 3-h lab periods, small everyday objects belonging to the students are reproduced as hydrogels by first creating negative templates in thermally cured…
