Here we present a new undergraduate laboratory that will introduce the concepts of time-resolved spectroscopy and provide insight into the natural time scales on which chemical dynamics occur through direct measurement. A quantitative treatment of the acquired data will provide a deeper understanding of the role of quantum mechanics and various…

A laboratory experiment in which students recycle silver and platinum selectively from spent screen-printed platinum electrodes is described. The recovered silver in solution is used to show its spontaneous redox reaction with a copper sheet. The recovered platinum is electrodeposited onto a screen-printed carbon electrode to develop a sensor for…

In 1972 Christian B. Anfinsen received the Nobel Prize in Chemistry for "…his work on ribonuclease, especially concerning the connection between the amino acid sequence and the biologically active conformation." The understanding of this principle is crucial for physical biochemistry students, since protein folding studies, bio-computing…

An advanced undergraduate organic chemistry laboratory experiment involving a rhodium-catalyzed intermolecular hydrocarbon C-H oxidation reaction is described. In the initial phase of this lab, students conduct a C-H amination reaction of ethylbenzene and isolate a benzylic amine product. In the second part of the lab, competition experiments are…

Rapid development in the field of reticular chemistry has allowed scientists ever-increasing control over the design and synthesis of crystalline porous materials. The promise that this field has in the development of next-generation materials for numerous applications (gas storage and separation, catalysis, chemical sensing, electronics) relies…

In this organic chemistry laboratory experiment, students are guided through a series of exercises to understand the behavior of compounds during liquid-liquid extraction. Aspects of density, structure, solubility, acid-base theory, and pK[subscript a] are all incorporated into activities that students complete in groups. After using their initial…

In this study, it was aimed to examine the experiment design skills of Biology and Science teachers and preservice teachers. For this purpose, 85 Biology and 80 Science teachers and preservices given information about laboratory approaches, experiment types and science process skills were asked to design an experiment about germination. In the…

The enrichment of plant foods with gamma-aminobutyric acid (GABA) is currently an interesting issue in the field of nutraceuticals and can be used as an experiment for upper-division undergraduate students. Here, an interdisciplinary hands-on experiment to produce GABA-enriched mung bean sprouts using common household reagents is described. Based…

Titration is a common introductory experiment performed across teaching laboratories from high school to university. Yet, its setup remains inaccessible for students with disabilities, denying them the opportunity for experiential learning. Therefore, rethinking such a setup is required to increase laboratory participation for these students. To…

Integrating authentic research-based experiences that mimic real-world scientific practices and relevance to student personal life into a chemistry curriculum can make abstract chemical principles more palpable to students. Unfortunately, many reported research-based experiences chemistry laboratory experiments lack relevance to a student's…

The purpose of this study was to develop a modern experimental apparatus using an Arduino with LabVIEW instead of the classical experiment. The wavelength of the sound was determined using the resonance of an air column. The smartphone app was used to generate the desired frequencies. A sound intensity and ultrasonic sensor was used to read the…

A bioinformatics laboratory experiment was designed to help undergraduate students learn RNA structure and function in biochemistry courses. In this laboratory experiment, students used 5S rRNAs as material to predict secondary structure and visualize three-dimensional (3D) structure. Students first downloaded molecular information from the 5S…

Purpose: Although technology is a defining characteristic of distance education, assessment of the applicability of such resources in knowledge dissemination is greatly warranted to ensure effectivity. Hence, the purpose of this study was to assess the viability of a novel tool in teaching practical chemistry online. Design/methodology/approach:…

CRISPR-Cas9 is revolutionizing how we conduct scientific research, treat disease, and develop new crops. The widespread impact of this genome-editing technology makes it critical for undergraduate students to understand and engage with this new tool. In this article, we describe a multi-week lab module that teaches undergraduates how to design…

Contribution: From the moment when universities began to talk about learning environment instead of classes and schools, a summative notion that entails knowledge transfer heralds an important stage of redefining the basic elements of learning. A learning environment requires the transition from learning rounding off toward open learning, without…
