James A. McKee; Emalie Rowles; Yumee Koo; James R. McKee – Journal of Chemical Education, 2023
Electrophilic aromatic substitution reactions are common in the organic chemistry laboratory. These reactions, while ubiquitous, use corrosive reagents and halogenated or hydrophobic solvents that produce expensive and hazardous waste streams. The carboxylation of phenols (Kolbe-Schmitt reaction), although aqueous, typically involves conditions…

Shuzhe Sun; Linxuan Wang; Jialin Qi; Zhenghu Xu – Journal of Chemical Education, 2023
A [beta]-lactam, the core structure unit of clinically important antibiotics such as penicillin and cephalosporin, is one of the most commonly encountered four-membered heterocycles in organic chemistry and is widely used in medicine and biochemistry. The Kinugasa reaction, a copper­(I)-catalyzed cycloaddition of a terminal alkyne with a nitrone,…

Ifat Parveen; Michael Rose; Helen C. Phillips; Stephen E. Flower; Timothy J. Woodman; Cameron A. Garty; Michael D. Threadgill – Journal of Chemical Education, 2023
An understanding of basic organic chemical reactivity is key for many biosciences students. The reactivities of different carbonyl groups affect their function in many biomolecules. A practical class, the two-step synthesis of paracetamol, has been devised to illustrate the electrophilic reactivities of carbonyls, which was covered in the…

Michael A. Araujo; Alexandra A. Barrere; Selena-Rae Tirado; Candace E. Williams; Monica I. Strada; Benjamin J. Alper – Journal of Chemical Education, 2022
Using crystal structure data, site directed mutagenesis, and real-time kinetic assays, students designed, expressed, and purified engineered mutants of human insulin-degrading enzyme (IDE). Students designed their own IDE mutants following "in silico" analysis, used inverse PCR to generate mutant plasmid expression constructs, expressed…

Simbarashe Nkomo; Alia Bly – Journal of Chemical Education, 2024
In undergraduate science education, laboratory courses stand as essential cornerstones of experiential learning. Chemistry laboratory courses offer students unique hands-on experiences that bridge the gap between theoretical knowledge and practical application. The journey through the undergraduate chemistry curriculum is paved with a series of…

Lisa Smith; D. M. Nirosh Udayanga; Xiaolin Qian; Lauren Adams; Sarah Sims; Charles Nettles; Xue Xu; Xin Cui; Deb Mlsna – Journal of Chemical Education, 2022
Catalysis and catalytic cycles are widely used in both research and industry. The addition of a catalysis experiment into the undergraduate laboratory curriculum is important and necessary training to expand student learning. Here, an experiment demonstrating iron-based tandem catalysis was developed and implemented in an organic chemistry course…

Keenan E. Dungey; Eric J. Voss; Susan D. Wiediger – Journal of Chemical Education, 2022
Nanotechnology has been recognized as an important driver of the future economy, and so nanoscience is increasingly being incorporated into the undergraduate chemistry curriculum. This experiment includes the chemical synthesis, optical and chemical testing, and microscopic imaging of gold nanoparticles. Since nanoparticles are too small to…

Lisensky, George; McFarland-Porter, Ross; Paquin, Weltha; Liu, Kangying – Journal of Chemical Education, 2020
Nanoparticle Zn[subscript 2x] Cu[subscript 1-x] In[subscript 1-x] S[subscript 2] is a promising and safer alternative to lead- and cadmium-containing quantum dots. Students prepare Zn[subscript 0.44] Cu[subscript 0.78] In[subscript 0.78] S[subscript 2] quantum dots in a one-pot synthesis without an inert atmosphere and investigate how the color,…

Shetranjiwalla, Shegufa; Leach, Nicole; Van Belle, Lori; Kingdon, Kassidy – Journal of Chemical Education, 2021
Is the reductionist approach to teaching chemical principles in the laboratory adequate for students to make effective evaluations? In this work, using the example of sunscreens, students first assessed the analytical chemistry parameters of the active ingredients, later comparing and contrasting them with organic chemistry information for…

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…

Bur, Scott K.; Pomerantz, William C. K.; Bade, Morgan L.; Gee, Clifford T. – Journal of Chemical Education, 2021
Curriculum-based undergraduate research experiences (CUREs) have been shown to increase student retention in STEM fields and are starting to become more widely adopted in chemistry curricula. Here we describe a 10-week CURE that is suitable for a second-semester organic chemistry laboratory course. Students synthesize small molecules and use…

Qianfu Luo; Chenyu Shi; Zhaoxia Wang; Meng Chen; Da-Hui Qu – Journal of Chemical Education, 2022
Given the importance of self-healing polymers for chemistry education, herein, we introduce our latest research results in self-healing materials based on thioctic acid into undergraduate chemistry laboratory. In this experiment, a natural small molecule, thioctic acid (TA), and a few other commercially-available reagents have been used to make a…

Huggins, Michael T.; Kesharwani, Tanay; Buttrick, Jonathan; Nicholson, Christopher – Journal of Chemical Education, 2020
Nuclear magnetic resonance (NMR) spectroscopy has become a cornerstone tool for studying a variety of molecular features in advanced chemistry laboratories. In this experiment, students prepare a pyrrole-[beta]-amide via a one-pot, three-step synthesis and use NMR spectroscopy to confirm its molecular structure. In addition, variable temperature…

Hu, Zheng-Li; Ying, Yi-Lun; Huo, Ming-Zhu; Kong, Xuan-Feng; Yu, Xiao-Dong; Zhang, Jian-Rong; Long, Yi-Tao – Journal of Chemical Education, 2020
The prompt introduction of single-molecule science into undergraduates' curricula is an urgent but challenging task. However, the research experiments are often too complicated and the instruments are too expensive to be widely transferred into a compulsory course of undergraduate students. Herein, we introduce a recently developed nanopore…
