Erceg, Ruzica; MaksimovicĀ“, Jelena P.; Pagnacco, Maja C. – Journal of Chemical Education, 2021
Ultraviolet (UV)-visible (Vis) spectroscopy is widely used in all modern laboratories as a routine method of analysis. The monitoring of chemical reactions in an aqueous solution involving a gas product is a demanding task but particularly for oscillatory reactions which are obtainable in a narrow concentration range. In this work, the…

Perera, Viveka; Acharya, Baku; Patrick, Amanda L.; Mlsna, Deb – Journal of Chemical Education, 2020
Mass spectrometers are ever-increasingly powerful, user-friendly, and affordable. Thus, the addition of mass spectrometry experiments into the undergraduate laboratory curriculum is now both feasible and an effective tool to introduce students to relevant instrumentation. Here an experiment demonstrating the use of a high-resolution electrospray…

Williams, Jacob L.; Miller, Martin E.; Avitabile, Brianna C.; Burrow, Dillon L.; Schmittou, Allison N.; Mann, Meagan K.; Hiatt, Leslie A. – Journal of Chemical Education, 2017
Many instrumental analysis students develop limited skills as the course rushes through different instruments to ensure familiarity with as many methodologies as possible. This broad coverage comes at the expense of superficiality of learning and a lack of student confidence and engagement. To mitigate these issues, a peer-led team learning model…

Soares, Pedro; Fernandes, Carlos; Chavarria, Daniel; Borges, Fernanda – Journal of Chemical Education, 2015
In recent years, the use of boron-containing reagents in palladium-assisted C-C coupling reactions (the Suzuki reaction) has gained prominence due to the vast array of reagents commercially available. Consequently, the generation of carbon-carbon bonds, namely of functionalized biphenyl systems, is at present considered the backbone of organic…
