Shuang Qiu; Dongyang Zhang; Vishal Yeddu; Cristina Cordoba; Arthur M. Blackburn; Violeta Iosub; Makhsud I. Saidaminov – Journal of Chemical Education, 2023
When structure-property relationships are discussed in inorganic chemistry and materials science, the common perception is that materials with the same composition and atomic arrangement have the same properties. In this laboratory experiment, we show that "processing"--the exact conditions under which materials are made--can in fact…

Beni B. Dangi; Maggie A. Cooper; Nathaniel Carnegie; Judy Clark – Journal of Chemical Education, 2025
A laboratory experiment has been designed for teaching laboratories aimed at training students in the basics of spectroscopy in junior and senior level undergraduate chemistry courses. Despite the ubiquity of light-based tools in modern science, students often find it difficult to comprehend light and light-matter interactions. A portable…

Petty, Anthony J., II; Odom, Susan A. – Journal of Chemical Education, 2021
An operationally simple, reliable synthesis of ethynylated acenes suitable for an upper-division undergraduate organic chemistry laboratory course has been developed. This experiment requires students to synthesize two acene derivatives and can be completed in 6-8 laboratory sessions (3 h each); a shorter experiment could be realized in the…

Rafal Fran´ski – Journal of Chemical Education, 2024
The area of application of electrospray ionization mass spectrometry (ESI-MS), usually coupled with liquid chromatography, seems to be much larger than those of any other ionization method. It gives rise to the demand for new teaching methods that would effectively help students to master the principles of working with and making full use of the…

Lianwen Zhu – Journal of Chemical Education, 2024
A chemistry laboratory experiment is described to introduce undergraduate college students to membrane separation technology. This experiment combines a simple nanowire membrane fabrication and visually indicated molecule separation. The membrane is produced via coprecipitation synthesis followed by a filtration assembly process, which can be…

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…

Trought, Mikhail; Perrine, Kathryn A. – Journal of Chemical Education, 2021
Surface chemistry impacts technology, advancing the development of new heterogeneous catalysts, semiconductor devices, and materials synthesis. Carbon surfaces are ubiquitous in various fields, and the surface reactivity can be altered by surface functionalization on the molecular scale, introducing functional groups, thus shifting their…

Timothy S. Eckert – Journal of Chemical Education, 2023
Approximations can help to orient the student in an organic chemistry laboratory. There the student needs to develop the solvent systems for the reaction and isolation of organic reactants and products. The adage "like dissolves like" helps in this regard, but this approach is vague and entirely qualitative. More quantitative approaches…

Daniele Crisafulli; Giulia Savoca; Francesca Mancuso; Martina Mazzaferro; Marco Milone; Ilenia Pisagatti; Anna Notti; Melchiorre F. Parisi; Giuseppe Gattuso – Journal of Chemical Education, 2024
In this two-session experiment for an organic chemistry lab, students prepare a macrocyclic host compound--namely, a pillar[5]arene--by means of a templated 1,4-dimethoxybenzene/formaldehyde cyclo-oligomerization (session 1), and then, they explore its molecular recognition properties toward the 1,8-diaminooctane guest with the aid of [superscript…

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…

Midori Tanaka; Toshimichi Shibue – Journal of Chemical Education, 2023
High-resolution mass spectrometry (HRMS) is an analytical technique that is typically used by mass spectrometry experts. However, with recent advancements, it is becoming more accessible to students in organic chemistry laboratories. Still, a significant knowledge gap exists between these experts and students. A straightforward laboratory…

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…

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…

Jonathan Quinson – Journal of Chemical Education, 2023
Gold nanoparticles (AuNPs) are textbook model systems to introduce "Nanomaterials" and "Nanotechnology" to students and laypersons. AuNPs are also suitable materials to raise awareness about the "Green Chemistry" principles. The unique optical and catalytic properties of nanosized gold make it ideal to timely develop…
