Exploring Chemical Equilibrium for Alcohol-Based Cobalt Complexation through Visualization of Color Change and UV-vis Spectroscopy
Peer reviewed Peer reviewed
Direct linkDirect link
Ren, Jolie; Lin, Tiffany; Sprague, Leonard W.; Peng, Iris; Wang, Li-Qiong – Journal of Chemical Education, 2020
Introducing chemical equilibrium concepts in undergraduate general chemistry promotes improved understanding of chemical reactions. We have developed an engaging laboratory experiment exploring the equilibrium of cobalt complexation in alcohols using UV-vis spectroscopy and successfully implemented in a large general chemistry class of 378…

Kirk, Riley D.; Carro, Marina A.; Wu, Christine; Aldine, Mohamad Jamal; Wharton, Alex M.; Goldstein, Danielle G.; Rosario, Margaret E.; Gallucci, Gina M.; Zhao, Yiwen; Leibovitz, Elizabeth; Bertin, Matthew J. – Journal of Chemical Education, 2021
Chemical screening libraries often feature natural product extracts (NPEs) due to the intriguing biological activities they possess and the structural diversity found in their individual components. A research project originally designed to create an extract library of every specimen in the University of Rhode Island (URI) Heber W. Youngken Jr.…

Hopson, Russell; Lee, Po Yin Bowie; Hess, Kathless M. – Journal of Chemical Education, 2018
One dimensional (1-D)[superscript 1] H and [superscript 13]C NMR experiments are common tools used in undergraduate organic laboratories to characterize synthesized molecules. However, 1-D NMR spectra cannot always provide unambiguous structure determination. In research laboratories, advanced NMR spectroscopy methods are employed for structural…

Levine, Mindy; Serio, Nicole; Radaram, Bhasker; Chaudhuri, Sauradip; Talbert, William – Journal of Chemical Education, 2015
There continues to be a persistent, widespread gender gap in multiple STEM disciplines at all educational and professional levels: from the self-reported interest of preschool aged students in scientific exploration to the percentages of tenured faculty in these disciplines, more men than women express an interest in science, a confidence in their…

A Novel Approach to Physiology Education for Biomedical Engineering Students
Peer reviewed Peer reviewed
Direct linkDirect link
DiCecco, J.; Wu, J.; Kuwasawa, K.; Sun, Y. – Advances in Physiology Education, 2007
It is challenging for biomedical engineering programs to incorporate an indepth study of the systemic interdependence of cells, tissues, and organs into the rigorous mathematical curriculum that is the cornerstone of engineering education. To be sure, many biomedical engineering programs require their students to enroll in anatomy and physiology…
