Landstrom, Evan B.; Nichol, Meghan; Lipshutz, Bruce H.; Gainer, Morgan J. – Journal of Chemical Education, 2019
Micellar catalysis has become an important aspect of the chemical industry's effort to "go green". However, this chemistry has yet to be fully explored in educational settings such as second-year organic chemistry laboratories. Reported herein is a discovery-based nucleophilic aromatic substitution experiment that introduces chemistry…

Tsokou, Aimilia M.; Howells, Alix; Stark, Moray S. – Journal of Chemical Education, 2019
The ability to handle chemicals safely is a key aspect of the learning development of students studying chemistry; however, there have been no previously reported investigations of the quantity of chemicals spilled by students during lab experiments. Therefore, the first part of this article reports the assessment of the volume of chemicals…

Alneyadi, Aysha; Shah, Iltaf; Ashraf, Syed Salman – Biochemistry and Molecular Biology Education, 2019
Active-learning strategies such as undergraduate research courses and course-based undergraduate research experiences (CUREs), which engage students in the practical experiments, have been reported as efficient ways for effective teaching and training of graduating students. Recently, many practical examples have been published in various fields…

Stanish, Paul C.; Siu, Howard; Radovanovic, Pavle V. – Journal of Chemical Education, 2019
Inorganic phosphors are the main component of light emitting diodes which have caused the revolution in lighting industry as an energy-efficient and long-lasting replacement of traditional incandescent light bulbs and fluorescent tubes. They are also used in various consumer products and displays and can potentially find applications in…

Morales, Christine; Chen, Franklin – Journal of Chemical Education, 2019
The effects of substitution on reaction rates are at the heart of both physical chemistry and organic chemistry. In this paper, we present a computational laboratory module to explore the effects of group substitution and isotopic substitution on reaction rates by using a readily accessible graphical interface, a computational engine, and…

Alho, J.; Silva, H.; Teodoro, V.; Bonfait, G. – Physics Education, 2019
In the field of physics teaching, the simple pendulum provides a very simple way to study the harmonic oscillator, the source of some fundamental concepts such as periodicity, relaxation time and anharmonicity. As such, its experimental study is frequently integrated into high school or first year university programs. With this in mind, in this…

Destino, Joel F.; Cunningham, Katie – Journal of Chemical Education, 2020
In light of COVID-19 in spring 2020, we developed a simple and versatile inquiry-based, laboratory-style active learning colorimetry experiment amenable to at-home quantitative analysis. In this experiment, students acquire an external calibration method using aqueous solutions of a self-selected chromophoric analyte from household products using…

Kelley, Elizabeth W. – Journal of Chemical Education, 2020
Due to the COVID-19 pandemic, education at all levels has temporarily shifted to remote learning, hobbling an integral component of chemistry courses: the laboratory. The chemistry lab is crucial for developing student engagement and learning with hands-on, relevant experiments in a socially dynamic classroom setting. The transition to remote…

Al-Soufi, Wajih; Carrazana-Garcia, Jorge; Novo, Mercedes – Journal of Chemical Education, 2020
We present our experience with transferring a four-day photometry and dye-adsorption laboratory experiment to the kitchens of students of Applied Thermodynamics from our degree in "Industrial Chemical Process Engineering". The students designed and built a double-beam photometer using their smartphones and household materials, then…

An organic solar cell fabrication kit has been developed for demonstration in both undergraduate teaching classes and high school laboratories to promote the growing field of renewable energy and to facilitate empirical comprehension of solar technology. The laboratory focuses on fabricating organic photovoltaics (solar cells) and testing the…

Barnett, Kerry L.; Shea, Kevin M.; McGeough, Catherine; Trotta, Kristine; Williams, Steven; Ly, Minh; Aloisio, Kathryn – Journal of Chemical Education, 2020
A semester-long research project for second-semester organic chemistry lab sections was developed. Student projects were based on preliminary data from faculty research that suggested the natural product neurolenin B to be a treatment for lymphatic filariasis. Students isolated neurolenins from the Central American plant "Neurolaena…

George-Williams, Stephen R.; Ziebell, Angela L.; Thompson, Christopher D.; Overton, Tina L. – International Journal of Science Education, 2020
Previous work at Monash University has shown that students recognise that inquiry-, problem-, context- and industry-based experiments were better contextualised, more open to decision making and aided in the development of scientific and transferable skills. This study investigated whether these gains persisted over a longer time scale, rather…

Kairouz, Vanessa; Collins, Shawn K. – Journal of Chemical Education, 2018
An undergraduate teaching laboratory experiment involving a continuous flow, bleach-mediated oxidation of aldehydes under biphasic conditions was developed that allowed students to explore concepts of mixing or mass transport, solvent sustainability, biphasic reactions, phase transfer catalysis, and continuous flow chemistry.

Cagle, Ethan C.; Totsch, Timothy R.; Erdmann, Mitzy A.; Gray, Gary M. – Journal of Chemical Education, 2018
[superscript 31]P{[superscript 1]H} nuclear magnetic resonance spectroscopy is a particularly useful tool for studying the reactions of P-donor ligands such as phosphines and phosphites with transition metals and other Lewis bases because the reactions take place on the nonbonding pair of electrons on the phosphorus. In addition, [superscript 31]P…
