Hanson, Benjamin S.; Brown, Christa P.; Laurent, Harrison; Hughes, Matt D. G.; Dougan, Lorna – Physics Education, 2020
Hierarchical structure and mechanics are crucial in biological systems as they allow for smaller molecules, such as proteins and sugars, to be used in the construction of large scale biological structures exhibiting properties such as structural support functionality. By exploring the fundamental principles of structure and mechanics at the…

Enlow, Jessica L.; Marin, Dawn M.; Walter, Michael G. – Journal of Chemical Education, 2017
To improve polymer education for 9-12 and undergraduate students, a plastic electronics laboratory kit using polymer semiconductors has been developed. The three-module kit and curriculum use polymer semiconductors to provide hands-on inquiry activities with overlapping themes of electrical conductivity, light emission, and light-harvesting solar…

Umar, Yunusa – Journal of Chemical Education, 2014
A simple and effective hands-on classroom activity designed to illustrate basic polymer concepts is presented. In this activity, students build primary structures of homopolymers and different arrangements of monomers in copolymer using paper clips as monomers. The activity supports formation of a basic understanding of polymer structures,…

Horta, Arturo; Pastoriza, M. Alejandra – Journal of Chemical Education, 2007
Various methods for the determination of the molecular weight distribution (MWD) of different polymer samples are presented. The study shows that the molecular weight averages and distribution of a polymerization completely depend on the characteristics of the reaction itself.

Hladky, Paul W. – Journal of Chemical Education, 2007
Random-climb models enable undergraduate chemistry students to visualize polymer molecules, quantify their configurational properties, and relate molecular structure to a variety of physical properties. The model could serve as an introduction to more elaborate models of polymer molecules and could help in learning topics such as lattice models of…
