Jordan, Annalisa M.; Wilke, Ashley E.; Nguyen, Tanifa L.; Capistrant, Katelyn C.; Zarbock, Katie R.; Batiste Simms, Morgan E.; Winsor, Brandi R.; Wollack, James W. – Journal of Chemical Education, 2022
Multistep synthesis is a key capstone experience in organic laboratory instruction. Here, a four-step synthesis of avobenzone, an active component in sunscreens, has been developed that can be completed in two 4 h laboratory periods. This synthesis incorporates green principles and includes an aldol condensation, electrophilic addition of bromine…

Yousef, Abraham L.; Smith, Alexis G. – Journal of Chemical Education, 2022
A multistep synthesis of a novel arylidene 3­(2"H")-furanone has been designed and optimized for the second-year organic laboratory. The three-step sequence consists of a nucleophilic substitution, intramolecular cyclization, and acid-catalyzed aldol condensation, and can be carried out within two 3 h laboratory periods. The final…

Laguta, Anna N.; Eltsov, Sergey V.; Mchedlov-Petrossyan, Nikolay O. – Journal of Chemical Education, 2021
This experimental lab set is for students taking college chemistry courses. It includes four laboratory works and completely illustrates the important parts of chemical kinetics, namely the determination of the rate constant and the determination of the factors influencing its value. They can be used in a laboratory set for a physical chemistry…

Oliveira, Karol N.; Naujorks, Amanda C.; Freitas, Welica P. S.; Goncalves, Alem-Mar B.; Calheiro, Lisiane B. – Journal of Chemical Education, 2021
The use of radioactive isotopes in radioactive decay studies can be a problem due to the manipulation of radioisotopes, expensive equipment, and the difficulty of finding samples with a reasonable half-life (between 1 and 10 min). In this paper, we present a mock-up of a Geiger-Mu¨ller counter plus three fictitious radioisotopes. They form an…

Li, Yunhua; Chen, Cuixue; Ye, Meiling; Imbault, Alexander Luis – Journal of Chemical Education, 2022
Organizing undergraduates in chemistry, energy engineering, and chemical engineering specialties to participate in an energy transformation experiment can encourage them to think about the impact of human activities on nature and stimulate them to learn more about the topic. This laboratory experiment demonstrates a general approach to the…

Daniela De Luchi; Renato Bonomi – Journal of Chemical Education, 2023
Scientists have always been fascinated by transient far-from-equilibrium systems. Since the (early) 1970s, there have been literature reports on the implementation of didactic experiments as a tool for attracting and stimulating students' and general public interest. In this work, a group of 12 high school students, supported by their chemistry…

Pradhan, Siddhartha Kumar; Balaji, Umapathi; Mishra, Soma; Jeevitha, Manjaiah; Swain, Shubhashree – Journal of Chemical Education, 2020
Raman spectroscopy is an important vibrational spectroscopy tool to characterize chemical compounds. As only a few photons undergo Raman scattering, enhancement of signal is a vital requirement. In this laboratory experiment, some practical aspects of Raman spectroscopy and how a simple enhancement procedure can be used to detect a Raman signal…

Christianson, Anna M.; Waters, Carolyn A. – Journal of Chemical Education, 2022
We describe a guided-inquiry laboratory experiment for instrumental analysis in which our students test an improved protocol for the recycling of silver chloride to produce nontoxic waste. Students are provided with samples of silver chloride that they created as waste products in a previous lab experiment and tasked with performing a stepwise…

Li, Zihao; Ganda, Sylvia; Melodia, Daniele; Boyer, Cyrille; Chapman, Robert – Journal of Chemical Education, 2020
We present the use of an oxygen tolerant controlled radical polymerization (photoinduced electron/energy transfer-reversible addition fragmentation chain transfer polymerization, PET-RAFT) as a simple method for preparing controlled radical polymers in an undergraduate laboratory. Unlike conventional techniques, PET-RAFT polymerizations require no…

Carter, Ashley R. – Physics Teacher, 2021
Introductory lab courses have been a staple of the physics curriculum for over 100 years. Yet these courses are now poised for change as recent research shows that they do not meet a frequent goal of enhancing student understanding of lecture content. In thinking about how to move forward, a look back at experiment courses in history seems wise.…
