Karlie Bach; Ryan P. Loughran; Alyssa Johnson; Eliseo Quiroz; Jacob M. Lessard; Kyle T. Smith; Nan Chieh Chiu; Makenzie T. Nord; Michael W. Burand; Margaret Haak; Kyriakos C. Stylianou – Journal of Chemical Education, 2024
Metal-organic frameworks (MOFs) are porous materials composed of metal ions and organic ligands. These materials have garnered significant attention due to their wide-ranging applications, such as the capture of hazardous molecules, catalysis, production of value-added compounds, and detection of ions or molecules in water. Despite their immense…

Stefan J. Hammerschmidt; Fabian Barthels; Annabelle C. Weldert; Christian Kersten – Journal of Chemical Education, 2024
Isothermal titration calorimetry (ITC) is the method of choice for thermodynamic binding profiling. As a label-free in-solution technique, ITC experiments do not require modified or immobilized proteins or ligands and hence can be performed under close-to-native environmental conditions. It directly follows the released heat of the molecular…

Takahiro Suzuki; Misaki Fujino; Yoji Yamada – Journal of Chemical Education, 2023
A laboratory experiment is proposed, wherein students fabricate a glucose fuel cell, use it to operate a solar motor, and investigate its performance. First, a fuel cell catalyst is prepared by plating palladium on two nickel wire meshes using an aqueous palladium chloride solution containing sodium dodecyl sulfate, an anionic surfactant that…

Chang, Ming-Mei – Biochemistry and Molecular Biology Education, 2022
Southern blot analysis is an important molecular biology technique for identifying a specific sequence in DNA samples. Although it is no longer used extensively in recent years, the steps and underlying principles of Southern blot are applicable to modern biology. High sensitivity and limited background are keys to successful Southern blots,…

Mikaela Sadri; Paul Smith; Samaria Spears; Jonathan Perkins; Carl Dewitt; Shane Savannah; Cameron Butler; Zhe Qiang – Journal of Chemical Education, 2023
Plastic waste is a growing concern in recent years due to the massive increase in single-use plastic applications. Despite the ever-increasing amount of waste, recycling plastics is not a simple process due to difficulties in sorting, which results in significantly downgraded material properties. This hands-on lab experiment showcases the…

Xiang Peng; Baochai Xu; Yujie Zeng; Song Xie; Zhanhui Zhang – Journal of Chemical Education, 2024
Removing the pollutants from various wastewater is crucial to the environment, ecology, and humans. However, the pollutants are generally removed by chemical decomposition, which not only consumes a lot of energy but also produces carbon emissions. Electrochemical flocculation is effective to extract pollutant molecules and heavy ions from…

Yufei Wang; Rebecca J. Abergel – Journal of Chemical Education, 2023
In view of the mounting requirements for courses in nuclear chemistry and radiochemistry, hands-on experience in the separations of radioisotopes is imperative. Three separation techniques commonly used were introduced, coprecipitation, liquid-liquid extraction, and ion-exchange chromatography. Their principles and the associated fundamental…

James A. Ciaccio; Baran Ak; Kareem Hassan – Journal of Chemical Education, 2023
The pharmacologically active lignans sesamin and sesamolin are minor components of sesame oil and ingredients in OTC dietary supplement capsules. We report an introductory undergraduate organic laboratory experiment combining natural product isolation and spectral analysis in which students isolate a mixture of sesamin and sesamolin by either (1)…

Joshua H. Williams; Musbau Gbadomosi; Andrew B. Greytak; Michael L. Myrick – Journal of Chemical Education, 2023
We describe an experiment in which students use research-grade instrumentation to collect gas adsorption data in triplicate in a single 3 h laboratory period. The experiment reinforces the thermodynamic concepts taught in upper level physical chemistry courses and hands-on experience with instrumentation used in research laboratories. The speed of…

Cui, Jinyan; Zhan, Wei – Journal of Chemical Education, 2022
Successful demonstration of lipid assembly chemistry to a general audience can be challenging on both physical (nanoscopic dimensions of lipid assemblies) and intellectual (complex, interconnected concepts) accounts. Quite often, an instructor has to leave key concepts out of what is being offered due to time constraints, which unfortunately…

Murray, Jaclyn Kuspiel – Physics Teacher, 2022
Discovering concepts through observation, exploration, and constructing scientific explanations of phenomena is best practice in science education. Instead of following lab procedures to verify a known answer or solution, involve students in the work of science. Begin by presenting a phenomenon to engage students in scientific inquiry and uncover…

Simin Cheng; Zhuoning Xie; Qingyuan Hu; Yao Qian; Xiaoxiao Ma – Journal of Chemical Education, 2023
This study highlights the importance of incorporating modern mass spectrometry techniques into undergraduate education. By focusing on the structure-characterizing capability of MS, students are able to gain hands-on experience with cutting-edge techniques and better understand how MS can be used to solve real-world problems. The three-step lipid…

Horikoshi, Ryo; Shirotani, Dai; Shioyama, Hiroshi – Journal of Chemical Education, 2022
Buckminsterfullerene (C[subscript 60]), along with diamond and graphite, appears in many chemistry textbooks as an example of an allotrope of carbon. This communication describes a hands-on activity to explore the characteristic structure of C[subscript 60] through the construction of a structural model using transistors and plastic tubes…
