Campbell, Dean J.; Brewer, Emily R.; Martinez, Keri A.; Fitzjarrald, Tamara J. – Journal of Chemical Education, 2017
The purpose of this laboratory experiment is to study fundamental concepts of kinetics and equilibria and the isotope effects associated with both of these concepts. The concepts of isotopes in introductory and general chemistry courses are typically used within the contexts of atomic weights and radioactivity. Kinetic and equilibrium isotope…

O'Brien, Leah C.; Root, Hannah B.; Wei, Chin-Chuan; Jensen, Drake; Shabestary, Nahid; De Meo, Cristina; Eder, Douglas J. – Journal of Chemical Education, 2015
Isothermal titration calorimetry was used to experimentally determine thermodynamic values for the ethylenediaminetetraacetic acid (EDTA)(aq) + M[superscript 2+](aq) reactions (M[superscript 2+] = Ca[superscript 2+] and Mg[superscript 2+]). Students showed that for reactions in a N-(2-hydroxyethyl)piperazine-N"-ethanesulfonic acid (HEPES)…

Kuhn, Misty L.; Figueroa, Carlos M.; Aleanzi, Mabel; Olsen, Kenneth W.; Iglesias, Alberto A.; Ballicora, Miguel A. – Biochemistry and Molecular Biology Education, 2010
Higher education institutions and scientific funding agencies are emphasizing international projects that involve the integration and synergy between research groups, particularly if different disciplines are involved. Students with an education that reflects these trends will have more tools to succeed in the future, but it is challenging to…

Jain, Prashant K.; Gu, Yuxiang; Rizwan-uddin – Advances in Engineering Education, 2008
Internet extends the reach of existing laboratory and training infrastructure to beyond the walls of such facilities. Though nothing can replace the hands-on experience in a laboratory; a carefully developed web-based digital lab may be the next best thing. In some cases, there may be benefits associated with a "distance laboratory" that…
