Organic electrosynthesis is an increasingly popular tool for driving and probing redox reactions. Recent advances in this field often employ an electrocatalyst to enhance the selectivity and efficiency of electrochemical reactions. A laboratory experiment was developed to introduce students to relevant mechanistic techniques in electrochemistry…

In an idealized General Chemistry Laboratory curriculum, students would hone their experimental design ability with practice encouraged by laboratory exercises designed to be open-ended. However, traditional General Chemistry Laboratory courses often lack opportunities for students to design their own experiments, instead opting to provide…

Highly efficient microwave-assisted organic synthesis is now commonplace in both industry and academia. Recently, a conductively heated sealed-vessel reactor was introduced that acts very similarly to a microwave reactor and is more affordable. Application of such reactors in teaching laboratories is advantageous because of the restricted window…

In this article we describe the construction of a low-cost electronic device to adapt the widespread traditional approach of Analytical Chemistry teaching into laboratory experimentation based on the guided research model. To this aim we construct a portable electronic instrument based on the Arduino microcontroller and use it to develop various…

In general, undergraduate experimental physics laboratories do not usually have experiments designed to address rolling friction and to measure the value of the rolling friction coefficient. This work explores an experiment, which has the potential to arouse students' curiosity about rolling friction by addressing a counterintuitive aspect of the…

Nuclear magnetic resonance (NMR) spectroscopy has become a cornerstone tool for studying a variety of molecular features in advanced chemistry laboratories. In this experiment, students prepare a pyrrole-[beta]-amide via a one-pot, three-step synthesis and use NMR spectroscopy to confirm its molecular structure. In addition, variable temperature…

Green chemistry metrics and life-cycle analysis (LCA) were used to assess inefficiencies in two current organic chemistry experiments conducted in third-year organic chemistry to synthesize ("E")-stilbene from benzaldehyde. An alternative Wittig-based, greener, one-pot experiment using the same starting material was selected as a vehicle…

A research-style laboratory experiment for advanced undergraduate students is described, which includes the synthesis, characterization, and properties (porosity, stability, amphipathy) testing of the composite [Cu[subscript 2](BTC)[subscript 4/3](H[subscript 2]O)[subscript 2][subscript 6][HPW[subscript 12]O[subscript 40]·(C[subscript…

This work reports the first use of rubber latex waste as the hydrophobic reagent for a low-cost, simple, and rapid fabrication of a paper towel-based experimental device (PTED) with a circular design of 5 mm to demonstrate the factors affecting chemical equilibrium; this serves as a user-friendly means for a laboratory experiment. The illustration…

Introducing chemical equilibrium concepts in undergraduate general chemistry promotes improved understanding of chemical reactions. We have developed an engaging laboratory experiment exploring the equilibrium of cobalt complexation in alcohols using UV-vis spectroscopy and successfully implemented in a large general chemistry class of 378…

A contemporary undergraduate laboratory experiment incorporating parallel microscale experimentation was developed for the well-defined palladium catalyzed Suzuki-Miyaura cross coupling of 4-fluorophenylboronic acid with both 4-chloro- and 4-bromoanisole using 11 diverse phosphine ligands and one ligandless control. This laboratory introduces…

The objective of this study was to examine the effectiveness of blended physics laboratory experimentation on pre-service physics teachers' (PSPTs') understanding of the nature of science (NOS) during an electricity and magnetism laboratory course. The study used a non-equivalent comparison group using a pre-test-post-test quasi-experimental…

The chemistry of metal-organic frameworks (MOFs) has the potential to introduce high school and undergraduate students to the fundamental chemical principles of structure and bonding, enhance the development of skills in synthesis and crystal growth, and promote hands-on experience with gas capture and host-guest chemistry of emerging materials…

This project report highlights a simple yet effective outreach lab benefiting the community partner, specifically the Alameda Point Collaborative (APC) youth program and Saint Mary's College students in a general science course. Building on a partnership focused on reciprocity, a portable lab experiment (Mattson Microscale Gas Chemistry lab) was…

Along with the COVID-19 pandemic, universities in Turkey as well as all over the world have started to carry out their education activities with the distance education method. In this case, many difficulties were encountered in the application of the Biology course, which is one of the applied courses carried out in the laboratory. Virtual…
