Nasse, Joseph A.; McAteer, Daniel; Hughes, Karlton D.; Kelbon, Christopher; Mugweru, Amos; Grinias, James P. – Journal of Chemical Education, 2019
Instruction on the design of analytical instrumentation is a critical component of the analytical chemistry curriculum. To simplify this process and enable students to directly see how the instruments that are in their own laboratory setting work, the use of augmented reality technology can be implemented. In this report, the "HP Reveal"…

Njoki, Peter N. – Journal of Chemical Education, 2019
A laboratory experiment has been developed to illustrate the transformation of silver nanoparticles (Ag NPs) in water containing phosphate anions. The experiment, conducted by high school students, involved hands-on learning to synthesize and characterize Ag NPs via ultraviolet-visible (UV-vis) spectroscopy. This was followed by a UV-vis probe of…

Rathod, Balraj B.; Murthy, Sahana; Bandyopadhyay, Subhajit – Journal of Chemical Education, 2019
"Is this solution pink enough?" is a persistent question when it comes to phenolphthalein-based titration experiments, one that budding, novice scientists often ask their instructors. Lab instructors usually answer the inquiry with remarks like, "Looks like you have overshot the end point", "Perhaps you should check the…

Lazenby, Katherine; Rupp, Charlie A.; Brandriet, Alexandra; Mauger-Sonnek, Kathryn; Becker, Nicole M. – Journal of Chemical Education, 2019
Understanding the nature and purpose of models, including mathematical models, is critical to enabling undergraduate chemistry students to use models to predict and explain phenomena. However, students often do not have systematic conceptions about different kinds of models. To gain a sense of how students understand different models in the…

Venable, T. Leon – Journal of Chemical Education, 2019
In a two-step synthesis starting with Ni(CH[subscript 3]COO)[subscript 2] ·4H[subscript 2]O and salicylaldehyde, students prepare Nethyl and N-isopropyl Ni(II) Schiff base (imine) complexes. After isolation and recrystallization, the products are characterized by room-temperature magnetic susceptibility measurements, FTIR spectroscopy, and…

Ferraro, Giovanni; Fratini, Emiliano – Journal of Chemical Education, 2019
A procedure for one-pot preparation and characterization of silver 1D nanostructures is described. The main advantages of this synthetic approach are the simplicity and reproducibility, where the size of the final product can be controlled just by changing the reaction time. This experiment is designed as a laboratory introduction to colloidal…

Abell, Timothy N.; Bretz, Stacey Lowery – Journal of Chemical Education, 2019
Learning thermodynamics requires understanding abstract topics such as entropy and spontaneity. Students tend to rely on metaphors and everyday meanings to reason about these topics. This study investigates how students explain dissolution and precipitation using the concepts of entropy and spontaneity. Students from general chemistry, physical…

Kondinski, Aleksandar; Parac-Vogt, Tatjana N. – Journal of Chemical Education, 2019
Single-type, 8-fold-grooved, commercially accessible interlocking disks (ILDs) have been used for modeling of complex polyhedral and reticular topologies with relevance to inorganic and hybrid materials. The assembly of complex topologies relies on the preparation of secondary building units (SBUs), which exhibit different connectivity than that…

Warzecha, Evan; Berto, Timothy C.; Wilkinson, Chad C.; Berry, John F. – Journal of Chemical Education, 2019
A new undergraduate inorganic chemistry laboratory experiment is presented. An introduction of the spectrochemical series and ligand exchange is explored using the coordination complex dirhodium tetraacetate, Rh[subscript 2](OAc)[subscript 4]. Students have measured the absorption spectra of the Rh[subscript 2] complex in the presence of various…

Pérez-Mariño, Ángel M.; Blanco, M. Carmen; Buceta, David; López-Quintela, M. Arturo – Journal of Chemical Education, 2019
Until now, the concept of metal (0) atomic quantum clusters or nanoclusters (NCs) and their increasing role in nanotechnology due to their novel and exceptional properties in important industrial fields (such as catalysis) has not been included at the education level. Here, syntheses of both metal nanoparticles (NPs) and metal nanoclusters (with…

Malinak, Steven M.; Hertzog, Jerald E.; Pacilio, Julia E.; Polvani, Deborah A. – Journal of Chemical Education, 2019
Laboratory experiments that offer interdisciplinary experiences for students are appealing and are increasingly popular additions to undergraduate chemistry curricula. Students can capitalize on their knowledge of multiple areas of chemistry while working through an application, and this fosters the development of progressive problem-solving…

Sansom, Rebecca L.; Suh, Erica; Plummer, Kenneth J. – Journal of Chemical Education, 2019
Heat and enthalpy are challenging topics for general chemistry students because they are conceptually complex and require avariety of quantitative problem-solving approaches. Expert chemists draw on conditional knowledge, deciding when and under what conditions a certain problem-solving approach should be used. Decision-based learning (DBL)…

Kent, James E.; Bell, Nicholle G. A. – Journal of Chemical Education, 2019
NMR is a fundamental part of any undergraduate chemistry degree, and training students how to measure and interpret NMR spectra is essential for postgraduate research or chemistry-based careers. Traditionally, the undergraduate laboratory experience with NMR is restricted to sample submission for NMR analysis, which is typically conducted by a…

Snitynsky, Ryan B.; Rose, Kerry; Pegg, Jerine M. – Journal of Chemical Education, 2019
Since 2015, a partnership between the Canadian Glycomics Network and the University of Alberta's Centre for Mathematics, Science, and Technology Education has provided opportunities for high-school teachers to immerse themselves in academic research environments. Drawing upon this experience, the teacher participants have created a library of…

Young, Michael C.; Djernes, Katherine E.; Payton, John L.; Liu, Daniel; Hooley, Richard J. – Journal of Chemical Education, 2019
In response to the call for an increased emphasis from the American Chemical Society on including macromolecular studies in the undergraduate curriculum, a supramolecular-themed experiment was designed for undergraduate-level organic laboratory courses that provides a convenient platform to study physical behaviors of supramolecular assemblies.…
