Elgrishi, Noémie; Rountree, Kelley J.; McCarthy, Brian D.; Rountree, Eric S.; Eisenhart, Thomas T.; Dempsey, Jillian L. – Journal of Chemical Education, 2018
Despite the growing popularity of cyclic voltammetry, many students do not receive formalized training in this technique as part of their coursework. Confronted with self-instruction, students can be left wondering where to start. Here, a short introduction to cyclic voltammetry is provided to help the reader with data acquisition and…

Sanders, Wesley C.; Iles, Peter; Valcarce, Ron; Salisbury, Kyle; Johnson, Glen; Lines, Aubry; Meyers, John; Page, Cristofer; Vanweerd, Myles; Young, Davies – Journal of Chemical Education, 2018
This paper describes a laboratory exercise used to address the ongoing need for nanotechnology-related, hands-on laboratory experiences for undergraduate students. Determination of the electrochemical behavior of student-fabricated silver nanogrids is reported. Students successfully used cyclic voltammetry to analyze silver nanogrids printed using…

Cunningham, William Patrick; Xia, Ian; Wickline, Kaitlyn; Huitron, Eric Ivan Garcia; Heo, Jun – Journal of Chemical Education, 2018
A procedure for the study of structural differences and intermolecular attraction between ethanol and 1-butanol based in laboratory work is described. This study provides comparisons of data retrieved from both a determination of boiling point and gas chromatography traces for the mixture. The methodology reported here should provide instructors…

Underwood, Sonia M.; Posey, Lynmarie A.; Herrington, Deborah G.; Carmel, Justin H.; Cooper, Melanie M. – Journal of Chemical Education, 2018
As chemists, we understand that science is more than a set of disconnected facts. It is a way of investigating and understanding our natural world that involves things like asking questions, analyzing data, identifying patterns, constructing explanations, developing and using models, and applying core concepts to other situations. This paper uses…

Highland, Zachary L.; Saner, ChaMarra K.; Garno, Jayne C. – Journal of Chemical Education, 2018
Experiments are described that involve undergraduates learning concepts of nanoscience and chemistry. Students prepare nanopatterns of organosilane films using protocols of particle lithography. A few basic techniques are needed to prepare samples, such as centrifuging, mixing, heating, and drying. Students obtain hands-on skills with nanoscale…

Quattrucci, Joseph G. – Journal of Chemical Education, 2018
A new method for teaching advanced laboratories at the undergraduate level is presented. The intent of this approach is to get students more engaged in the lab experience and apply critical thinking skills to solve problems. The structure of the lab is problem-based and provides students with a research-like experience. Students read the current…

Raboh, Ghada – Journal of Chemical Education, 2018
A high performance liquid chromatography (HPLC) experiment for the upper level analytical chemistry laboratory is described. The students consider the effect of mobile-phase composition and pH on the retention times of ionizable compounds in order to determine the acid dissociation constant, K[subscript a], of a phenolic acid. Results are analyzed…

Jewitt, Sarah; Sutphin, Kathy; Gierasch, Tiffany; Hamilton, Pauline; Lilly, Kathleen; Miller, Kristine; Newlin, Donald; Pires, Richard; Sherer, Maureen; LaCourse, William R. – Journal of Chemical Education, 2018
This article examines the ways that a shared faculty experience across five partner institutions led to a deep awareness of the curriculum and pedagogy of general chemistry coursework, and ultimately, to a collaborative action plan for student success. The team identified key differences and similarities in course content and instructional…

Harrp, David N. – Journal of Chemical Education, 2018
Copying adjacent answer sheets on the oft-used multiple-choice exams can be prevented if exam material is scrambled. The latter mode has been a requirement for all exams of this type at McGill University for 26 years. Cheating by copying has been reduced to nearly zero in this time. The experiment carried out used permissive seating and a single…

Irby, Stefan M.; Borda, Emily J.; Haupt, Justin – Journal of Chemical Education, 2018
Here, we describe the implementation a hybrid general chemistry teaching laboratory curriculum that replaces a portion of a course's traditional "wet lab" experiences with online virtual lab modules. These modules intentionally utilize representations on all three levels of the chemistry triplet-macroscopic, submicroscopic, and symbolic.…

Avery, Patrick; Ludoweig, Herbert; Autschbach, Jochen; Zurek, Eva – Journal of Chemical Education, 2018
The "Yet Another extended Hu¨ckel Molecular Orbital Package" (YAeHMOP) has been merged with the Avogadro open-source molecular editor and visualizer. It is now possible to perform YAeHMOP calculations directly from the Avogadro graphical user interface for materials that are periodic in one, two, or three dimensions, and to visualize…

Minkiewicz, Piotr; Darewicz, Malgorzata; Iwaniak, Anna – Journal of Chemical Education, 2018
A simple equation to calculate the oxidation states (oxidation numbers) of individual atoms in molecules and ions may be introduced instead of rules associated with words alone. The equation includes two of three categories of bonds, classified as proposed by Goodstein: number of bonds with more electronegative atoms and number of bonds with less…

Niemeyer, Emily D.; Zewail-Foote, Maha – Journal of Chemical Education, 2018
The use of electronic response pads or "clickers" is a popular way to engage students and create an active-learning environment, especially within large chemistry courses. We examined students' perceptions of how the clicker affected their learning, participation, and engagement in the classroom, as well as their overall experience…

Namwong, Pithakpong; Jarujamrus, Purim; Amatatongchai, Maliwan; Chairam, Sanoe – Journal of Chemical Education, 2018
In this article, a low-cost, simple, and rapid fabrication of paper-based analytical devices (PADs) using a wax screen-printing method is reported here. The acid-base reaction is implemented in the simple PADs to demonstrate to students the chemistry concept of a limiting reagent. When a fixed concentration of base reacts with a gradually…

Marek, Keith A.; Raker, Jeffery R.; Holme, Thomas A.; Murphy, Kristen L. – Journal of Chemical Education, 2018
For the past eight years, the ACS Examinations Institute has been developing Anchoring Concepts Content Maps for the different subdisciplines taught throughout the undergraduate curriculum. The structure of the map consists of two top levels that are shared throughout the entire curriculum and two subdiscipline specific levels that contain…
