Pavel V. Kolesnichenko; Axl Eriksson; Linnea Lindh; Donatas Zigmantas; Jens Uhlig – Journal of Chemical Education, 2023
Investigating the optical properties of various chemical compounds using UV-vis spectrophotometers is an essential part of education in chemistry. However, commercial spectrophotometers are usually treated as "magic black boxes", where the dominant majority of optical elements are hidden "under the hood". This often limits…

Priyadarshi Bopegedera, A. M. Ranjika – Journal of Chemical Education, 2022
Marble, formed by the metamorphism of limestone, is commonly used in the construction industry and sculpting. The mineral in marble is either calcite [CaCO[subscript 3]] or dolomite [CaMg(CO[subscript 3])[subscript 2]] or sometimes both. The pure white Carrara marble from Italy was made a household name by Michelangelo, the famous sculptor of the…

Pearson, Russell J. – Journal of Chemical Education, 2017
Different approaches to the use of "clickers" (also known as student response systems) were introduced to a cohort of 127 students over a two-year period with the aim of making students think more deeply in-class about their chemistry knowledge. Student performance was monitored, and individual, anonymous student feedback was frequently…

Evans, Steven T.; Huang, Xinqun; Cramer, Steven M. – Chemical Engineering Education, 2010
The commercial simulator Aspen Chromatography was employed to study and optimize an important new industrial separation process, weak partitioning chromatography. This case study on antibody purification was implemented in a chromatographic separations course. Parametric simulations were performed to investigate the effect of operating parameters…
