Laboratory astrophysics and astrochemistry are emerging fields highlighting the importance of laboratory simulations and experiments to benefit remote observations. In particular, ice mixtures found in the outer solar system may offer insight into the early evolution of organic molecules. H[subscript 2]O-ice mixtures containing other species such…

Blue (B), yellow (Y), red (R), and green (G) color-changing dye was used in a general chemistry course for first-year undergraduate students with nonscience majors to highlight the redox reactions written as the gain and loss of hydrogen. The first experiment is a vibrant color variation using a synthetic dye of indigo carmine. The second…

Academic integrity is often a concern instructors have when teaching, with past research indicating the classroom environment is one of the largest factors in determining students' likelihood to cheat. In this commentary, we intend to start a dialogue with instructors regarding the importance of creating a classroom environment that values…

Antioxidants are molecules that act against free radicals, and this effect can bring many benefits to health and society. Antioxidants can be found in various matrices of nature, such as fruits and plants. Some studies have shown that "Rhizophora mangle," a typical mangrove plant, is rich in antioxidants. People report its use for…

There is an increasing need for fundamental electrochemistry concepts to be taught in the undergraduate curriculum, given the broad applicability of electrochemical technologies in addressing a wide range of global issues from critical energy shortages to real-time medical diagnostics. However, many electrochemical concepts are often taught in…

This article presents computational chemistry exercises that are designed to be incorporated into an undergraduate physical chemistry course. This activity teaches computational chemistry as it is performed in higher-level research (in a command-line environment and executed on a high-performance computing cluster) to provide students with a…

Thin-layer chromatography, which involves the movement of dyes along a silica-coated plate, is used to observe the progress of chemical reactions and to separate mixtures. We took advantage of this phenomenon to devise a method for generating patterns in the shape of numbers with dots (dot matrix). We prepared the azo dyes necessary for generating…

Understanding the basics of d-electron configuration and the spin state of coordination complexes are essential elements of undergraduate inorganic chemistry. However, students in these courses find it difficult to conceptualize the ideas. Here, we have developed an undergraduate laboratory experiment that allows students to systematically…

CACAO (Chocolate Across the Curriculum and Outreach) is a vertical curriculum augmentation designed to help students across the ChE undergraduate program. The students use a chocolate-based food engineering lab to make connections between core chemical engineering topics using hands-on and project-based learning. Costs to create this component are…

Proton nuclear magnetic resonance ([superscript 1]H NMR) spectroscopy is an essential characterization tool for organic chemists widely taught in the undergraduate chemistry curricula. Previous work has focused on how students advance from novice to expert in interpreting [superscript 1]H NMR spectra. However, we need to know more about how…

Molecular imprinting technology holds significant potential for applications in chemical analysis and detection. In order to integrate the fundamental knowledge of polymer chemistry, electrochemistry, and analytical chemistry with practical applications and cutting-edge research, we proposed a comprehensive experiment of the preparation,…

The mercury beating heart is a dramatic demonstration of redox chemistry that allows for the direct conversion of chemical energy to mechanical energy without involving a machine to accomplish the transfer. Unfortunately, instructors often avoid this demonstration due to difficulties initiating the oscillating redox reaction that drives the…

The use of open-source materials is growing in popularity throughout higher education. This Communication investigates the impact on student performance in a second-year undergraduate analytical chemistry course when an open-source textbook is assigned. For two separate semesters, approximately 80 students were enrolled in such a course across…

Fluorescence analysis is an important technology, which can obtain the concentration of target analytes through comparing the fluorescence intensity change of a fluorescent sensor. Generally, the fluorescence intensity is measured by a fluorometer. However, many undergraduates have no chance to operate such an expensive instrument. Besides, the…

The introduction of Computational Chemistry via "Molecular Modelling and Drug Design" course at undergraduate level has opened wide possibilities for students to expand their knowledge of quantum chemistry, organic reaction mechanisms, protein-ligand interactions, drug design, and probable "in vivo" behavior of drug candidates.…
