Walden, Sarah L.; Frisch, Hendrik; Unterreiner, Barbara V.; Unterreiner, Andreas-Neil; Barner-Kowollik, Christopher – Journal of Chemical Education, 2020
The prompt transfer of cutting-edge science into students' curricula is a challenging task. Often research experiments are too complex or expensive to be translated into a secondary or tertiary education setting. Herein, we introduce a laboratory experiment that translates the recently developed research technique of a wavelength dependent,…

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…

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…
