Ruiz, Kevin A.; López, Marta; Suppan, Gottfried; Makowski, Kamil – Journal of Chemical Education, 2020
We present an experiment designed to hone the decision-making skills of (undergraduate) chemistry students by using aqueous crossed aldol reactions. Here, we present two simple crossed aldol reactions based on inexpensive and readily available materials: The condensation of vanillin and cinnamaldehyde with acetone. The procedure uses the variation…

Brown, Lesley R. – Biochemistry and Molecular Biology Education, 2006
This laboratory exercise encourages upper level biochemistry students to build and expand upon previously developed laboratory skills and knowledge as they conduct a comparison of two methods of plasmid preparation based upon cost, quality of product, production time, and environmental impact. Besides creating an environment that mimics a more…
