Schmidt, Jonas; Huber, Tim; Mu¨ssig, Jo¨rg – Journal of Chemical Education, 2022
The knowledge of the mechanical properties of polymers and other materials is essential for several tasks in the field of materials science, like component design and material development. The tensile test is one method of determining many of the material's most defining mechanical characteristics. However, the teaching of laboratory experiments…

Esvan, Yannick J.; Zeinyeh, Wael – Journal of Chemical Education, 2020
The Fourier transformation (FT) is a mathematical process frequently encountered by chemistry students. However, it remains an automated background process perceived by many students as difficult to understand. In this paper we present a simple open-source web application, which can help students to understand the basics of the FT applied to…

Jordheim, Lars Petter; Denuzie`re, Anne; Machon, Christelle; Zeinyeh, Wael – Journal of Chemical Education, 2021
The understanding of the basic principles of chromatography is of high importance for chemistry, pharmacy, and biology students. In this paper, we present a free web application which can be used as a teaching tool to introduce chromatography to undergraduate students, using one of the simplest chromatography models: the plate theory.

Priya Yadav; Harshita Laddha; Madhu Agarwal; Ragini Gupta – Journal of Chemical Education, 2022
A smartphone-based digital imaging method has been successfully introduced in an undergraduate laboratory class to quantify fluoride ions in water. Students first synthesized the chemosensor (E)-2-(1-(6-nitro-2-oxo-2H-chromen-3-yl)ethylidene)-N-phenylhydrazine-1-carbothioamide (CT) via an eco-friendly and green microwave-assisted protocol and…

Vergne, Matthew J.; Smith, J. Dominic; Bowen, Ryan S. – Journal of Chemical Education, 2020
An online virtual escape-room game was created using the Google Forms survey app for an undergraduate chemistry lab class. Zoom video conferencing service was used to make the activity a collaborative learning experience. The theme was an escape from an abandoned chocolate factory, and the students solved problems to move to the next section or…

An, Jiwoo; Poly, Laila-Parvin; Holme, Thomas A. – Journal of Chemical Education, 2020
In general chemistry laboratories, students learn practical laboratory skills through hands-on activities and are exposed to new scientific instruments. However, these instruments are often viewed as black boxes for various reasons, where students do not know how to use them or what the instruments are capable of. This tendency is likely to induce…

Montangero, Marc – Journal of Chemical Education, 2015
When dissolving copper in nitric acid, copper(II) ions produce a blue-colored solution. It is possible to determine the concentration of copper(II) ions, focusing on the hue of the color, using a smartphone camera. A free app can be used to measure the hue of the solution, and with the help of standard copper(II) solutions, one can graph a…

Bandyopadhyay, Subhajit; Rathod, Balraj B. – Journal of Chemical Education, 2017
An Android-based application has been developed to provide color-blind and visually impaired students a multisensory perception of color change observed in a titration. The application records and converts the color information into beep sounds and vibration pulses, which are generated by the smartphone. It uses a range threshold of hue and…

Hensiek, Sarah; DeKorver, Brittland K.; Harwood, Cynthia J.; Fish, Jason; O'Shea, Kevin; Towns, Marcy – Journal of Chemical Education, 2016
Building on previous success with a digital pipet badge, an evidence-centered design approach was used to develop new digital badges for measuring the volume of liquids with a buret and making a solution in a volumetric flask. These badges were implemented and assessed in two general chemistry courses. To earn the badges, students created videos…

van der Kolk, Koos; Hartog, Rob; Beldman, Gerrit; Gruppen, Harry – Journal of Science Education and Technology, 2013
Increasingly, mobile applications appear on the market that can support students in chemistry laboratory classes. In a multiple app-supported laboratory, each of these applications covers one use-case. In practice, this leads to situations in which information is scattered over different screens and written materials. Such a multiple app-supported…

Chlad, Frank L.; Hardy, James K. – Journal of Chemical Education, 1983
Safety procedures used by Department of Chemistry at the University of Akron are discussed. These include policy that no chemicals are stored in the teaching laboratories. Instead, dispensing stockrooms are used to service the laboratories. Other aspects discussed include ventilation procedures and development of microprocessor use in stockrooms.…
