T. Leon Venable – Journal of Chemical Education, 2024
As an introduction to quadrupolar effects in NMR spectroscopy, students use low field ([superscript 1]H, 60 MHz), benchtop [superscript 13]C NMR spectroscopy to contrast the spin-spin coupling behavior of [superscript 13]C to the dipolar [superscript 1]H and quadrupolar [superscript 2]D in familiar solvents C(H/D)Cl[subscript 3], C(H/D)[subscript…

Anoshia Khan; Cristina Altamirano; Yousuf Khan; Haroon Saeed; Tyler Moreira; Troy T. Handlovic; Mohammed R. Elshaer; Justin A. Bogart – Journal of Chemical Education, 2023
Many of the current synthetic methodologies utilized within academic and industrial laboratories require knowledge of how to safely handle air- and moisture-sensitive reagents and work under inert atmospheres. As a result, the ACS Committee on Professional Training recommends incorporating synthetic methods that make use of these inert atmospheres…

Lagares, Antonio, Jr.; Garavaglia, Matías Javier; Robledo, Natalia Belén; Valverde, Claudio; Goñi, Sandra Elizabeth; Lozano, Mario Enrique – Journal of Biological Education, 2022
Regulation is a key concept for understanding the dynamics of metabolism in bacteria. This report outlines a simple laboratory experiment aimed at studying a key form of regulation in bacterial metabolism, exemplifying how microbes switch the flux of carbon towards alternative metabolic fates as a function of nutrient availability and according to…

Mei Zhang; Wangmin Hu; Wenjing Liu; Chang Lei; Jun Guo; Hongcai Shang; Junling Hou – Journal of Chemical Education, 2022
Interdisciplinary experiments within chemistry are very important for the improvements in the overall quality of the education received by students. In this work, we describe an interdisciplinary experiment that was successfully completed by undergraduate students. This training integrates multiple disciplines including natural product medicinal…

Gerard G. Dumancas; Noemi Carreto; Oliver Generalao; Guoyi Ke; Ghalib Bello; Arnold Lubguban; Roberto Malaluan – Journal of Chemical Education, 2023
Chemometric techniques such as partial least-squares (PLS) regression have been applied with huge success to a wide array of chemical problems including multicomponent analysis of analytes in complex mixtures. Despite this, there are few examples of laboratory pedagogical exercises that involve students in the acquisition of chemical data from…

Vaclav Matousek; Radek Matuska; Tomas Vranka; Martin Adamec; Tadeas Herentin; Jiri Kalacek; Jan Havlik – Journal of Chemical Education, 2023
Triboluminescence is a fascinating phenomenon that can engage students' interest in chemistry. However, safe, cost-effective, and accessible laboratory experiments featuring highly triboluminescent substances are limited. To bridge this gap, we present a simple, rapid, semimicro test tube preparation of the visually engaging manganese complex…

Stewart, John F.; Gustafson, John E.; Moore, Michael E.; Forshee, J. Lance; Canaan, Patricia; French, Donald P. – American Biology Teacher, 2023
Students who experience research as undergraduates tend to remain in science, technology, engineering, and mathematics fields. Since course-based undergraduate research experiences (CUREs) are often expensive to implement, we developed a relatively inexpensive first-semester research course for majors entitled "Freshman Research in…

Alexander Grushow – Journal of Chemical Education, 2022
A revised version of a traditional physical chemistry laboratory experiment has been developed to enhance student discussion in the laboratory and to improve students' connections between physical chemistry concepts and real molecular systems. In this experiment, students explore the keto-enol tautomerization of 2,4-pentanedione. However, unlike…

Keiner, Liz; Graulich, Nicole – Chemistry Education Research and Practice, 2021
Understanding ongoing chemical processes in the laboratory requires constant shifting between different representational levels--the macroscopic, submicroscopic, and symbolic levels--and analysis of the various mechanistic features of each of these levels. Thus, the ability to explain observations of chemical phenomena with regard to their…

Bopegedera, A. M. R. P.; Coughenour, Christopher L. – Journal of Chemical Education, 2021
A new project-based laboratory (PJBL) was developed for general chemistry students to tackle the steps involved in chemical water quality analysis using an accessible, real-world hydrologic system (the lakes of the Lower Grand Coulee, Washington). This PJBL was developed in a joint general chemistry and environmental geology course by a…

Niu Huang; Chao Li; Shili Gan; Cancan Le; Huan Liu; Wei Liu; Liqun Ye – Journal of Chemical Education, 2022
With the benefits of low cost, energy efficiency, and environmental protection, photocatalytic hydrogen production is considered to be the most promising technology for the development of a clean and sustainable society. However, the utilization of photocatalytically generated hydrogen is not very common yet. Therefore, tertiary education urgently…

Kylie L. Luska – Journal of Chemical Education, 2022
A multioutcome, guided inquiry-based liquid--liquid extraction (LLE) experiment has been designed for introductory organic chemistry. Multiple outcomes were established by identifying a series of red and blue dyes that are (1) soluble in organic solvent, (2) soluble in aqueous solution, or (3) soluble in either the organic or aqueous layers by…

Cook, Ryan; Hannon, Drew; Southard, Jonathan N.; Majumdar, Sudipta – Biochemistry and Molecular Biology Education, 2018
A one semester undergraduate biochemistry laboratory experience is described for an understanding of recombinant technology from gene cloning to protein characterization. An integrated experimental design includes three sequential modules: molecular cloning, protein expression and purification, and protein analysis and characterization. Students…

Budner, Drew; Simpson, Brett – Journal of Chemical Education, 2018
Students entering into a quantitative analysis course often struggle with connecting theoretical aspects of concepts from lecture to hands-on applications in the laboratory setting. A one-semester quantitative analysis course was redesigned to integrate active learning with a project-based curriculum that incorporated structured review of…

Alaimo, Peter J.; Langenhan, Joseph M.; Suydam, Ian T. – Journal of Chemical Education, 2014
Many traditional organic chemistry lab courses do not adequately help students to develop the professional skills required for creative, independent work. The overarching goal of the new organic chemistry lab series at Seattle University is to teach undergraduates to think, perform, and behave more like professional scientists. The conversion of…
