Perera, Viveka; Acharya, Baku; Patrick, Amanda L.; Mlsna, Deb – Journal of Chemical Education, 2020
Mass spectrometers are ever-increasingly powerful, user-friendly, and affordable. Thus, the addition of mass spectrometry experiments into the undergraduate laboratory curriculum is now both feasible and an effective tool to introduce students to relevant instrumentation. Here an experiment demonstrating the use of a high-resolution electrospray…

Easdon, Jerry – Journal of Chemical Education, 2020
Experiments written for students who were quarantined during the COVID-19 pandemic are described. These were developed to provide hands-on lab experiences that students would not get due to the online nature of course offerings during the crisis. The laboratories described include an extraction and oxidation of aldehydes from food items, a study…

Patel, Parth H.; Conrad, Kristofer L.; Pathiranage, Anuradha L.; Hiatt, Leslie A. – Journal of Chemical Education, 2020
Given student familiarity with electronic cigarettes (e-cigs), this lab uses a student-built smoke collection apparatus to collect e-cig vapors to teach students about gas chromatography-mass spectrometry (GC-MS). Students in a second semester, introductory organic chemistry course spent 1 week collecting e-cig vapors and 1 week qualitatively…

Mete, Pelin – Journal of Science Learning, 2023
In the present study, atmospheric pressure, an abstract concept that learners generally have difficulty understanding and explaining, was presented to pre-service elementary teachers (PSTs) with the method of argumentation. The argument levels of the PSTs were examined using the Predict-Observe-Explain (POE) experiments in teaching the subject of…

Yan Cong; Baojun Wang; Taili Du – International Journal of Information and Communication Technology Education, 2023
In order to make up for the shortage of scientific research experiments and teaching in land-based engine room laboratory, a simulation system is designed and developed using B/S mode to simulate scientific research experiments, teaching and operation processes, and designed algorithms to simulate the propulsion characteristics of the main…

Virginia Jiang; Matthew Lucia; Scott Banta; Christopher V. H.-H. Chen – Chemical Engineering Education, 2023
We developed a remote lab experience where freshmen grew and analyzed the activity of sourdough starters as a means of engaging with chemical engineering concepts. This six-week hands-on activity was targeted due to its low-cost, non-hazardous materials, and ability to be conducted safely in a non-laboratory setting. By designing the lab to be…

Matthew D. Hanson; Daniel P. Miller; Cholavardhan Kondeti; Adam Brown; Eva Zurek; Scott Simpson – Journal of Chemical Education, 2023
In this article, we describe a fully computational laboratory exercise that results in an increase of students' understanding of what quantum chemical geometry optimization calculations are doing to find minimum energy structures. This laboratory exercise was conducted several times over multiple years at a small private undergraduate institution,…

Adrian Saura-Sanmartin; Jorge Lopez-Sanchez; Carmen Lopez-Leonardo; Aurelia Pastor; Jose Berna – Journal of Chemical Education, 2023
The synthesis of a [2]rotaxane through three- or five-component coupling reactions has been adapted to an organic chemistry experiment for upper-division students. The experimental procedure addresses the search for the most favorable reaction conditions for the synthesis of the interlocked compound, which is obtained in a yield of up to 71%.…

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…

Antonia Fruntke; Mira Behnke; Leanne M. Stafast; Tom Träder; Elisabeth Dietel; Antje Vollrath; Christine Weber; Ulrich S. Schubert; Timm Wilke – Journal of Chemical Education, 2023
This publication presents a series of experiments in the field of nanomedicine for high school chemistry education and student laboratories, developed as a collaborative project between chemistry didactics and chemical research. In this context, polymeric nanocarriers represent a promising approach for drug delivery, acting as "smart…

Titikan Somboon; Wichien Sang-aroon; Sira Sansuk – Journal of Chemical Education, 2023
Undergraduate-level laboratory experiments that integrate multidisciplinary chemistry concepts into a single activity are very appealing and thought-provoking for chemistry students. Here, we use the oscillating chemical reaction to introduce students to the analytical detection concept. The Belousov-Zhabotinsky reaction is employed as a simple…

Arun Richard Chandrasekaran – Journal of Chemical Education, 2023
The field of DNA nanotechnology has grown rapidly in the past decade and has expanded to multiple laboratories. While lectures in DNA nanotechnology have been introduced in some institutions, laboratory components at the undergraduate level are still lacking. Undergraduate students predominantly learn about DNA nanotechnology through their…

Ilana J. P. Molesky; Michael W. Zuerch; Anne M. Baranger; Stephen R. Leone – Journal of Chemical Education, 2023
Ultrafast laser pump-probe spectroscopy is an important and growing field of physical chemistry that allows the measurement of chemical dynamics on their natural time scales, but undergraduate laboratory courses lack examples of such spectroscopy and the interpretation of the dynamics that occur. Here we develop and implement an ultrafast…

Paul Erik Olli; Tavo Romann – Journal of Chemical Education, 2023
Metal-air battery technology is a promising new energy storage solution in the green energy economy but also an excellent tool to educate students on the working principles of batteries. A simple yet powerful construction of a metal-air battery is shown, which consists of a plastic mint box, a cathode, an anode, and an electrolyte. Furthermore,…

Härtel, Hermann – European Journal of Physics Education, 2020
In the light of own measurements on a Faraday generator, the well-known theories concerning Unipolar Induction and the Faraday paradox seem to be problematic. On the other hand, all results obtained, and all other processes described as a paradox in connection with the Faraday generator can be explained without contradiction based on the theory of…
