Joseph S. Elias – Journal of Chemical Education, 2024
We report the design of a low-cost electrochemical workstation and open-source graphical user interface capable of performing a variety of electrochemical methods in an undergraduate teaching laboratory. The instrument--based on the popular Arduino microcontroller board--can be constructed from common components for $40 USD. The modular design of…

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…
