Ricca, John G.; Duersch, Bobby G.; Plaza, Tito S. Sempértegui; Haky, Jerome E. – Journal of Chemical Education, 2022
Elemental analysis is performed in a variety of ways in food and environmental sciences; thus, we have designed an activity in which students gain experience with research-level lab techniques in a real-world context through the quantification of key elements in breakfast cereals using microwave plasma optical emission spectroscopy (MP-OES). The…

Giancaspro, Joseph; Scollan, Patrick; Rosario, Juan; Miller, Elizabeth; Braziel, Samuel; Lee, Sunghee – Biochemistry and Molecular Biology Education, 2022
In an upper-division interdisciplinary laboratory experiment, students use Raman spectroscopy to highlight how the overall structure and conformational order of lipid bilayers can be influenced by their individual phospholipid composition. Students prepare a supported lipid bilayer, as a model cell membrane, by spreading liposomes made of various…

Barreto, Candida; Soltanlou, Mojtaba – South African Journal of Childhood Education, 2022
Background: Educational research has been conducted mainly by using behavioural approaches. Whilst such methods provide invaluable insights into the field, several important questions such as 'how do we learn?' and 'what mechanisms cause individual differences?' cannot be answered thoroughly by using only behavioural approaches. In the last three…

Thompson, Frank – Physics Education, 2022
An absorption line at 900 nm has been observed in Perspex. Samples of 1 and 2 cm thickness were used and the integrated absorption (line width times peak absorption) of the line was proportionate to the thickness. Facilities for lowering the sample temperature were not available and therefore both measurements were carried out at room temperature.…

Shannon L. Goes; Jordan E. Nutting; Nicholas J. Hill; Shannon S. Stahl; Mohammad Rafiee – Journal of Chemical Education, 2022
As electrochemistry continues to gain broader acceptance and use within the organic chemistry community, it is important that advanced undergraduate students are exposed to fundamental and practical knowledge of electrochemical applications for chemical synthesis. Herein, we describe the development of an undergraduate laboratory experience that…

Ioana Nicolau; Anca Paun; Codrut¸a C. Popescu; Niculina D. Ha?dade; Mihaela Matache – Journal of Chemical Education, 2023
This communication describes an updated experiment of peptide synthesis, involving determination of the loading capacity of a Fmoc-protected amino functionalized resin using UV-vis spectroscopy and a subsequent synthesis of a dipeptide in order to exemplify the experimental solid-phase synthesis procedure as an alternative technique in organic…

Will Jimy Quintero; Mo´nica Constanza A´vila; Cristian Ochoa-Puentes – Journal of Chemical Education, 2023
Cycloadditions in combination with multicomponent reactions are among the most valuable synthetic tools used by organic chemists to construct cyclic and heterocyclic compounds in a straightforward way. Although cycloadditions, such as the Diels--Alder reaction, are mainly covered in basic and advanced organic courses for undergraduate students,…

Linus Svenberg; Lovisa Malm; Narin Abdollahzadeh; Negar Gohari; Maria Almlo¨v; Annika Norin; Åsa Emmer – Journal of Chemical Education, 2023
The understanding of analytical chemistry and its application in different areas of life science is something that should be encouraged for students studying chemistry, and also something that appeals to many students. Life science includes a vast variety of areas, out of which some are more easily approached in student projects. The chemical…

Rajan Singh; Shweta Tiwari; Jyotirekha Jena; Rajiv K. Kar – Journal of Chemical Education, 2023
Low-dimensional materials especially graphene-based are of high interest to a broad community. One of the most fundamental aspects in the biomedical field is material characterization, which helps understand their property and tune for application. Though the existing teaching curricula are well standardized to include basic principles and…

Herasymchuk, Khrystyna; Raza, Rameez; Saunders, Paul; Merbouh, Nabyl – Journal of Chemical Education, 2021
Substitution reactions of alcohols are some of the simplest experiments performed in undergraduate organic chemistry laboratory settings. However, the use of gas chromatography (GC) as an analytical tool for these reactions can be at times laborious and time-consuming. In this work, 1-pentanol, 2-pentanol, 3-pentanol, and 2-methyl-2-butanol were…

Thaveesangsakulthai, Isaya; Kulsing, Chadin – Journal of Chemical Education, 2021
Optimization of experimental conditions in chromatography is recognized as a wear-and-tear process involving hundreds of experiments in order to maximize the number of separated compounds for each sample. The critical thinking skills and practices entailed cannot be achieved with students in a conventional lecture class. This report provides a…

Petty, Anthony J., II; Odom, Susan A. – Journal of Chemical Education, 2021
An operationally simple, reliable synthesis of ethynylated acenes suitable for an upper-division undergraduate organic chemistry laboratory course has been developed. This experiment requires students to synthesize two acene derivatives and can be completed in 6-8 laboratory sessions (3 h each); a shorter experiment could be realized in the…

Sengupta, Ishita – Journal of Chemical Education, 2021
Introducing elementary concepts of nuclear magnetic resonance spectroscopy (NMR) to a beginner can be challenging. Using an interactive graphical platform can greatly aid in demonstrating key concepts in such cases. This paper aims to bridge this gap in teaching basic NMR spectroscopy through simple standalone interactive Python programs or a…

Erceg, Ruzica; Maksimovic´, Jelena P.; Pagnacco, Maja C. – Journal of Chemical Education, 2021
Ultraviolet (UV)-visible (Vis) spectroscopy is widely used in all modern laboratories as a routine method of analysis. The monitoring of chemical reactions in an aqueous solution involving a gas product is a demanding task but particularly for oscillatory reactions which are obtainable in a narrow concentration range. In this work, the…

Savakinas, Mallory V.; Frey, Olivia M.; Piro, Nicholas A.; Rhile, Ian J.; Hamann, Christian S. – Journal of Chemical Education, 2021
Friedel-Crafts alkylation reactions using a curated set of alcohols provide students with the opportunity to combine the study of electrophilic aromatic substitution with carbocation rearrangements. In this experiment students may be presented with up to nine alcohols that yield six products, all synthesized under identical reaction conditions.…
