Mahaveer Genwa; Jyoti Singh; Alka Rani; Kushagra Yadav; Chetna Angrish – Journal of Chemical Education, 2024
Photochemical reactions are initiated by the absorption of light, triggering the chemical reactions and resulting in the formation of products. These reactions are generally performed using a freely available renewable source of energy-solar energy. Solar simulators mimic both the ultraviolet and visible regions of sunlight and hence can serve as…

Victoria Borish; H. J. Lewandowski – Physical Review Physics Education Research, 2023
Quantum mechanics is a field often considered very mathematical, abstract, and unintuitive. One way some instructors are hoping to help familiarize their students with these complex topics is to have the students see quantum effects in experiments in undergraduate instructional labs. Here, we present results from an interview study about what it…

Shane Harrypersad; John P. Canal – Journal of Chemical Education, 2023
The discovery of ferrocene, Fe(C[subscript 5]H[subscript 5])[subscript 2], in the 1950s sparked the development of organometallic chemistry including metallocene compounds. Shortly after the isolation of ferrocene, the analogous ruthenium and osmium compounds were discovered. The preparation of ferrocene is common in undergraduate inorganic…

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…

Shawn D. Montag – Journal of Chemical Education, 2023
The imine condensation reaction is commonly addressed in second semester organic chemistry classrooms as imines and their derivatives are found in many pharmaceutical scaffolds and biological and catalytic processes. Despite this, imine condensations are still absent from many organic chemistry laboratory curriculums. The work discussed here…

Adrian R. Hilts; Jason Cooke – Journal of Chemical Education, 2023
The addition of a small excess of triethyl orthoformate to an alcoholic mixture of NiCl[subscript 2]·6H[subscript 2]O and triphenylphosphine (PPh[subscript 3]) results in an increase in the typical isolated yield of [NiCl[subscript 2](PPh[subscript 3])[subscript 2]] from below 50% to over 85%. The impact of water when present in the reaction…

Lozovenko, O.; Minaiev, Yu; Lutai, R. – Physics Education, 2022
The purpose of this publication is to present a novel approach to the demonstration of the Dzhanibekov effect. The main idea of our version is to use a lightweight spinning top of a spherical external form but distinct principal moments of inertia floating in the upward flow of air. As a result, the Dzhanibekov effect can be easily demonstrated…

Loomis, Mario G.; Hines, Jonathon H.; Reynolds, Amberly M. – HAPS Educator, 2022
Tumescence in cadaveric dissection involves the introduction of fluid into interstitial spaces to assist in the separation of natural tissue planes and the preservation of delicate structures. With a hand surgeon's perspective, the senior author brought this technique into the cadaver lab. The infusion helped transform desiccated and adherent…

Ylva Hamnell-Pamment – Chemistry Education Research and Practice, 2024
Navigating the observational, symbolic, and theoretical knowledge domains of chemistry is crucial for chemistry sensemaking. However, this has been shown to be particularly challenging for students of chemistry. In order to reach government standards for sensemaking in the chemistry subject, it is important to investigate how chemistry teachers…
