Sumalatha Peddi; Jacob R. Franklin; C. Scott Hartley – Journal of Chemical Education, 2024
Chemical reactions that mimic the function of ATP hydrolysis in biochemistry are of current interest in nonequilibrium systems chemistry. The formation of transient bonds from these reactions can drive molecular machines or generate materials with time-dependent properties. While the behavior of these systems can be complicated, the underlying…

Wei Xiong; Huhu Yin; Xiujing Xing; Hao Li – Journal of Chemical Education, 2024
Although the present university-level chemistry experimental curriculum has been extensive and well-designed, it lacks a connection with the scientific research field, especially the frontier field. It is crucial to incorporate recent discoveries through new experiment designs to bridge this gap and boost the value of the undergraduate…

Yongguang Gao; Na Chen; Xiaoye Jiang; Xiaochun Yang – Journal of Chemical Education, 2024
The substitution of carbonyl compounds with liquid bromine as a brominating agent is the most commonly employed synthesis method for a-bromoacetophenone and its derivatives. However, liquid bromine possesses certain drawbacks, such as volatilization, high toxicity, strong corrosion, and poor reaction selectivity, which limit its application and…

Carmen Velez; Kristie Cheng; Sabrina Woodward; Noor Nazeer; Gabriela Nicole Hislop Gomez; Cody O. Crosby – Journal of Chemical Education, 2024
Many undergraduate chemistry and biochemistry students pursue careers in healthcare. Biomaterials, designed to harmonize with the complexity of the human body, have become increasingly significant in medicine as implants, drug delivery vehicles and tissue scaffolds. We believe it is essential that undergraduates are exposed to biomaterial…

Sanders, Wesley C.; Johnson, Glen; Valcarce, Ron; Iles, Peter; Fourt, Hunter; Drystan, Kyne; Edwards, Dakota; Vernon, Jarom; Ashworth, Spencer; Barucija, Amar; Curtis, Zachary – Journal of Chemical Education, 2019
A new experiment for use in introductory nanotechnology courses is described. This experiment allows students to fabricate metallic wires with microscale lateral dimensions and nanoscale vertical dimensions. Fabrication occurs in the capillaries of polydimethylsiloxane (PDMS) stamps modified with hydrophilic polymers. This experiment provides…

Sithole, Alec; Chiyaka, Edward T.; Mabwe, Kumbirai – Higher Education Studies, 2022
Our study evaluates students' approaches to and perceptions of the use of hands-on at-home laboratory kits (HALK) experiments, open-source computer-based simulations (OSCBS), and their combination (OSCBS-HALK) in undergraduate introductory asynchronous online physics courses. Anonymous survey data from students who had completed online physics…

Ambruso, Kelly; Riley, Kathryn R. – Journal of Chemical Education, 2022
In this communication, we describe five at-home laboratory experiments and demonstrations that complement a semester-long analytical chemistry curriculum. The experiments were successfully carried out by remote undergraduate students enrolled in a hybrid analytical chemistry course during the COVID-19 pandemic. Students used their personal…

Zhdanov, Arsenii; Pyay, Anna – Physics Teacher, 2022
Mobile phones are a widely used platform for educational apps, mobile health, and a variety of chemical tests. Here, we are working on a mobile phone-based physics lab (mPhysics) that uses a mobile phone's capabilities to run simple physics experiments and demonstrations. While a mobile phone can be used to analyze magnetic and optical properties…

Ang, Jayden Wei Jie – Journal of Chemical Education, 2021
A method to synthesize biaryls through the Suzuki-Miyaura cross-coupling reaction using a recyclable fluorous precatalyst is described. This laboratory experiment, which demonstrates the safety benefits of green chemistry, is integrated into an upper-division course. Besides simply using the catalyst for a reaction, students can reuse the catalyst…

Gehman, Courtney A.; Hantz, Eric R.; Hamann, Christian S. – Journal of Chemical Education, 2021
[superscript 1]H NMR spectroscopy is a molecular characterization technique that is ubiquitously used in research and teaching laboratories alike. Strategic deuteration of molecules is a commonly employed technique in the deconvolution of [superscript 1]H NMR signals. Here this approach is applied in a second-year chemistry course in which…

Talano, Melina A.; Ibañez, Sabrina; Sosa Alderete, Lucas G.; Wevar Oller, Ana L.; Vezza, Mariana E.; Medina, María I.; Agostini, Elizabeth – Journal of Biological Education, 2021
Universities play an important role in society and in providing solutions for its problems. Environmental pollution is one of the most serious problems facing the world today. Thus, universities are increasingly including subjects related to the environment and its conservation both in their educational and research programmes. Generally,…
