David Mainka; Julius Krause; Linus Großmann; Andreas Link; Lukas Schulig – Journal of Chemical Education, 2023
The pharmaceutical industry relies heavily on analytical techniques for identifying and characterizing drug compounds. In this experiment, undergraduate pharmacy students explored the applications of near-infrared spectroscopy for pharmaceutical analysis and its potential for identifying patterns and relationships among pharmaceutical samples. In…

H. Martin; E. Eisner; J. K. Klosterman – Journal of Chemical Education, 2023
3D printers have facilitated a wealth of 3D printed molecular models illustrating key structural concepts for student learning. However, general adoption of 3D printed models in the organic chemistry classroom proceeds slowly as the majority of consumer-grade 3D (fused deposition modeling (FDM) and resin) printers are inherently monochromatic,…

Derek J. Bischoff; Michael E. Mackay; Sheldon A. Hewlett – Journal of Chemical Education, 2024
Upper-division undergraduate students are introduced to polymer processing using material extrusion fused filament fabrication 3D printing to make poly(lactic acid) (PLA) mechanical testing specimens. Computer aided design and slicing software packages are used to demonstrate the process of preparing 3D computer models for printing. Following the…

David L. Myers; Marc Hill; Brooke Baughman; Eugene T. Smith – Journal of Chemical Education, 2023
This exercise encompassed the construction and use of a microcontroller-based laser refractometer. The instrument, which does not require a high skill level to build, primarily consisted of a line laser, optical sensor, several 3-D printed parts and printed circuit boards, and a microcontroller development board. Construction and testing of the…

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…

Lohning, Anna E.; Hall, Susan; Dukie, Shailandra – Journal of Chemical Education, 2019
Students often approach biochemistry with a degree of trepidation with many considering it one of the more difficult subjects. This is, in part, due to the necessity of making visual images of submicroscopic concepts. Molecular interactions underpin most biological processes; therefore, mastering these concepts is essential. Understanding the…

Tabassum, Tahseen; Iloska, Marija; Scuereb, Daniel; Taira, Noriko; Jin, Chongguang; Zaitsev, Vladimir; Afshar, Fara; Kim, Taejin – Journal of Chemical Education, 2018
3D printing technology has an enormous potential to apply to chemical engineering education. In this paper, we describe several designs of 3D printed mesoreactors (Y-shape, T-shape, and Long channel shape) using the following steps: reactor sketching, CAD modeling, and reactor printing. With a focus on continuous plug flow mesoreactors (PFRs, i.d.…
