The concept of co-amorphous systems is introduced in an integrated laboratory experiment, designed for advanced chemistry students, using solvent-free, environmentally friendly mechanochemistry. The dual-drug naproxen-cimetidine co-amorphous system (NPX-CIM) is investigated as an example of the emergent field of medicinal mechanochemistry.…

Materials science research has expanded significantly in recent years; a multidisciplinary field, home to an ever-growing number of chemists. However, our general chemistry degree courses have not changed to reflect the rise in interest in this topic. In this paper, we propose a laboratory experiment for the undergraduate chemistry practical…

Resonance is a foundational organic chemistry concept, but it is consistently misunderstood by undergraduate students. The development of a concept inventory--a multiple-choice assessment where the incorrect answer choices stem from commonly held alternate conceptions--on the concept of resonance could help organic chemistry instructors quickly…

Chemistry in water is an emerging field that fulfills the fifth principle of green chemistry: replacing toxic organic solvents with their benign counterparts. Although some pharmaceutical industries have developed and adopted chemistry in water, its implementation in teaching laboratories is still limited. Therefore, we have designed an experiment…

Chemistry is increasingly data centric and the undergraduate curriculum needs to adjust to keep up. To address this, we created the "Air Quality Activity," a new first-year undergraduate activity where students use Microsoft Excel to analyze a unique subset of atmospheric ozone (O[subscript 3]) and nitrogen dioxide (NO[subscript 2])…

This work presents a homemade multirole 3D-printed modular spectrometer(MPMS), which can be easily assembled like bricks and expanded with several modules to measure different types of spectra, such as UV-vis absorption, fluorescence emission, flame emission/absorption, glow discharge, and even Raman spectra. The spectrometer is designed to be…

Microplastics have been detected in most ecosystems around the world. They affect the environment and organisms in it, including humans and possibly their health. Hence, the analysis of microplastic occurrence in the environment is highly relevant. However, there are only a few practical and easy-to-implement methods published for school use, and…

The rate of the sonochemiluminescence reaction of luminol in alkaline medium can be increased in the presence of carbon tetrachloride, chloroform, and bromoform. The presence of the latter activators enhances the light emission, to allow studying the kinetics of this reaction in a 4-h laboratory session using a mobile phone camera as a detector…

According to the author, the "Australian Curriculum: Mathematics (AC:M) requires primary school students to measure the attributes of angle, time, temperature, length, area, capacity and mass. This article outlines some misconceptions held by primary school students which appear to stem from them not understanding terminology concerning the…

Educational games are effective learning tools frequently used to motivate students and enhance their engagement in the learning process. Using these games in challenging courses, such as organic chemistry, creates a more engaging and student-friendly learning environment that can enhance students' learning. Drawing organic compounds and…

A two-component undergraduate laboratory experience has been developed by students in a senior level capstone course. The first component is a 3 h laboratory experience dedicated to the rapid synthesis of a metal-organic framework (MOF-808) in aqueous solution using readily available reagents and equipment. During the second component, MOF-808 was…

This report outlines an approach for preparing 5-color 3D printed plastic models of molecular orbitals and electron density surfaces using a hobby-grade 3D printer. Instructions are provided for preparing 3D orbital and electron density surface (EDS) models using solid or mesh representations in ground state and transition state structures. We…

A cooperative-learning jigsaw-style activity was developed to create opportunities for introductory organic chemistry students to discuss and decipher [superscript 1]H NMR spectra. Students cooperatively interpreted spectra that contained both pure and mixed solvents, building consensus through explanation and argumentation on what each spectrum…

Catalysis is an essential concept in chemistry, playing a key role in industrial processes. Catalysis has been considered to be challenging not only for university students to comprehend but also for the teachers. In this Laboratory Experiment, we have described a simple activity for demonstrating the concept of catalysis using thread-based…

Protein structure and function are important concepts in the biochemistry curriculum. A three-part CURE was developed to be used in an undergraduate biochemistry course that enhances student learning of these aspects in addition to practicing oral and written communication skills. Students used three protein-protein docking programs (PRISM,…
