Pölloth, Benjamin; Teikmane, Ieva; Schwarzer, Stefan; Zipse, Hendrik – Journal of Chemical Education, 2020
A modular and target-group oriented online video library with 48 videos was developed and produced in order to reduce the complexity of an introductory organic chemistry laboratory class. The library comprises three different types of videos: "Tutorials" explaining fundamental laboratory techniques, "Do nots" pointing students…

Volpe, Kate; Podlesny, Erin E. – Journal of Chemical Education, 2020
A continuous flow photopinacol coupling of benzophenone has been developed and implemented in the undergraduate laboratory. This photoreduction was accomplished using 2-propanol as an H atom donor and cosolvent in the reaction. The simple and inexpensive UV light source and flow reactor design (less than $350/photochemical flow system) provide an…

Yearty, Kasey L.; Maynard, Ryan K.; Cortes, Christina N.; Morrison, Richard W. – Journal of Chemical Education, 2020
Williamson ether experiments are commonly performed by students in undergraduate organic chemistry instructional laboratory courses. In this multioutcome experiment, students were provided 4-bromophenol and one of three alkyl halides: 1-bromopentane, 1-bromobutane, or 1-bromo-3-methylbutane. The alkyl halides served as the unknown component of the…

McGarvey, David J. – Journal of Chemical Education, 2020
A laboratory experiment characterized by a whole-class data-pooling approach to generate a data set that can be used to test a model of the influence of ionic strength on electrolyte solubility is described and discussed. The design of the experiment makes efficient use of the laboratory period and releases time for instructional and dialogic…

Miao, Haoqian; Otsuki, Andrew L.; Beckett, Joseph O.; Mascal, Mark – Journal of Chemical Education, 2020
How well does the undergraduate organic chemistry laboratory curriculum prepare students for academic research, or for a bench job in industry? Running experiments that are more representative of research chemistry has the potential to better equip students for working in a research laboratory, while at the same time giving them insight into a…

Tao, Fujun; Garcia, Alma Valenzuela; Xiao, Ting; Zhang, Yuliang; Yin, Yansheng; Chen, Xiaobo – Journal of Chemical Education, 2020
Interfacial solar vapor generation has recently drawn much attention because of its high solar-to-vapor generation efficiency. Here we introduce the basic experimental procedures and analysis for undergraduates to perform such an experiment to catch up with the cutting-edge research wave. Interfacial solar vapor generation employs an interfacial…

Xu, Xicheng; Suganuma, Yoshinori; Dhirani, Al-Amin – Journal of Chemical Education, 2020
Lock-in amplifiers (LIAs) are commonly used in chemistry laboratories to improve noise-to-signal ratios. Constructing and testing a suitably designed LIA provide undergraduate students with an excellent opportunity to learn about theory, construction, and applications of LIA. In particular, students can learn about time-dependent behavior and…

Garrido, Neil; Pitto-Barry, Anaïs; Soldevila-Barreda, Joan J.; Lupan, Alexandru; Comerford Boyes, Louise; Martin, William H. C.; Barry, Nicolas P. E. – Journal of Chemical Education, 2020
The abstract nature of physical chemistry and spectroscopy makes the subject difficult to comprehend for many students. However, bridging arts and science has the potential to provide innovative learning methods and to facilitate the understanding of abstract concepts. Herein, we present a high-school project based on the conversion of selected…

King, Ryan P.; Wagner, Alexander J.; Burtea, Alexander; King, Susan M. – Journal of Chemical Education, 2020
An undergraduate organic chemistry experiment has been developed that features asymmetric synthesis of an enantioenriched secondary alcohol, followed by determination of its absolute configuration using the competing enantioselective conversion (CEC) method. Students are given a ketone and an unknown enantiomer of CBS (Corey-Bakshi-Shibata)…

Filipovic, Nicholas; Scott, Alison J.; Penlidis, Alexander – Chemical Engineering Education, 2021
As future chemical engineers, it is important that students be able to identify and quantify sources of error. A statistical analysis technique that is often overlooked is hierarchical design methodology, which allows for the separation of overall variance into several related components. While hierarchical methodology is relevant to many fields,…
