LeSuer, Robert J. – Journal of Chemical Education, 2019
Consumer-grade manufacturing tools such as 3D printers are becoming increasingly prevalent in STEM education environments, especially as tools to develop inexpensive, tactile visualization models. Presented here is a workflow for creating 3D-printed periodic tables displaying a variety of trends from traditionally taught relationships such as…

Jones, Oliver A. H.; Spencer, Michelle J. S. – Journal of Chemical Education, 2018
Using tangible models to help students visualize chemical structures in three dimensions has been a mainstay of chemistry education for many years. Conventional chemistry modeling kits are, however, limited in the types and accuracy of the molecules, bonds and structures they can be used to build. The recent development of 3D printing technology…

Paukstelis, Paul J. – Journal of Chemical Education, 2018
The increased availability of noncommercial 3D printers has provided instructors and students improved access to printing technology. However, printing complex ball-and-stick molecular structures faces distinct challenges, including the need for support structures that increase with molecular complexity. MolPrint3D is a software add-on for the…

Davis, Eric J.; Jones, Michael; Thiel, D. Alex; Pauls, Steve – Journal of Chemical Education, 2018
Additive manufacturing (3D printing) is a technology with near-unlimited potential for the chemical educator. However, its adoption into higher education has been limited by the dual requirements of expertise in 3D printing and 3D computer-aided design (CAD). Thus, its reported utilization in the chemistry curriculum has been within the creation…

Schmidt, Benjamin; King, David; Kariuki, James – Journal of Chemical Education, 2018
A reference electrode is an essential component of all three-electrode electrochemical measurements. Common commercial reference electrodes, including the saturated calomel electrode and Ag/AgCl reference electrode, are expensive with the former containing toxic mercury. Cheaper alternatives have been proposed including Ag/AgCl references made…

de Cataldo, Riccardo; Griffith, Kaitlyn M.; Fogarty, Keir H. – Journal of Chemical Education, 2018
Introductory chemistry students encounter the concept of hybrid orbitals as a transition from atomic orbitals to molecular bonding. The principal purpose of learning hybridization in the undergraduate curriculum is to impart an understanding of the origins of molecular bonding and geometry. Physical models of both individual hybrid orbitals and…

Pinger, Cody W.; Castiaux, Andre; Speed, Savannah; Spence, Dana M. – Journal of Chemical Education, 2018
Plasma protein binding measurements are an important aspect of pharmacology and drug development. Therefore, performing these measurements can provide a valuable and highly practical learning experience for students across many scientific disciplines. Here, we describe the design and characterization of a 3D-printed device capable of performing…
