Venable, T. Leon – Journal of Chemical Education, 2019
In a two-step synthesis starting with Ni(CH[subscript 3]COO)[subscript 2] ยท4H[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…

Bogucki, Ryan; Greggila, Mary; Mallory, Paul; Feng, Jiansheng; Siman, Kelly; Khakipoor, Banafsheh; King, Hunter; Smith, Adam W. – Journal of Chemical Education, 2019
Low cost, open-source analytical instrumentation has the potential to increase educational outcomes for students and enable large-scale citizen science projects. Many of these instruments rely on smartphones to collect the data, mainly because they can effectively leverage a dramatic price-to-performance ratio of the optical sensors. However,…

Dean, Natalie L.; Ewan, Corrina; McIndoe, J. Scott – Journal of Chemical Education, 2016
The use of hand-held 3D printing technology provides a unique and engaging approach to learning VSEPR theory by enabling students to draw three-dimensional depictions of different molecular geometries, giving them an appreciation of the shapes of the building blocks of complex molecular structures. Students are provided with 3D printing pens and…

Simpson, Scott; Lonie, David C.; Chen, Jiechen; Zurek, Eva – Journal of Chemical Education, 2013
A computational experiment that investigates single-walled carbon nanotubes (SWNTs) has been developed and employed in an upper-level undergraduate physical chemistry laboratory course. Computations were carried out to determine the electronic structure, radial breathing modes, and the influence of the nanotube's diameter on the…

Simpson, Scott; Autschbach, Jochen; Zurek, Eva – Journal of Chemical Education, 2013
A computational experiment that investigates the optical activity of the amino acid valine has been developed for an upper-level undergraduate physical chemistry laboratory course. Hybrid density functional theory calculations were carried out for valine to confirm the rule that adding a strong acid to a solution of an amino acid in the l…

Cardellini, Liberato – Journal of Chemical Education, 2010
Ronald J. Gillespie, the inventor of the Valence Shell Electron Pair Repulsion (VSEPR) model, relates how his career as researcher in Christopher Ingold's laboratories started. Gillespie developed a passion for chemistry and chemical education, searching for more appropriate and interesting ways to transmit the essential knowledge and enthusiasm…
