The Spring 2020 semester students were faced with the challenge of adjusting how they learned in the middle of the semester, as the situation changed from instructors holding group office hours and study sessions for the upcoming midterm exams to faculty and students scrambling to gather their belongings before the impending lockdown. Immediately…

The design of undergraduate laboratory courses that provide meaningful research-based experiences enhances undergraduate curricula and prepares future graduate students for research careers. In this article, a course-based undergraduate research experience (CURE) laboratory module was designed for upper-division undergraduate biochemistry and…

The chemistry of metal-organic frameworks (MOFs), a new class of emerging crystalline porous solids with three-dimensional (3D) networks composed of metals and multidentate organic molecules, was introduced by using three differently shaped crystals. We reported new and mild MOF synthesis methods that are simple and devised to be performed in high…

We present a showcase of our experience with videos complementing analytical chemistry lectures to familiarize undergraduate students with instrumental element analysis. This includes a detailed account of how we planned, produced, and utilized a video to review the course content at the end of the semester. The analytical case study focused on…

In this communication, we describe five at-home laboratory experiments and demonstrations that complement a semester-long analytical chemistry curriculum. The experiments were successfully carried out by remote undergraduate students enrolled in a hybrid analytical chemistry course during the COVID-19 pandemic. Students used their personal…

Auditory speech discrimination is essential for normal language development. Children born preterm are at greater risk of language developmental delays. Using functional near-infrared spectroscopy at term-equivalent age, the present study investigated early discrimination of speech prosody in 62 neonates born between week 23 and 41 of gestational…

Nuclear magnetic resonance (NMR) spectra are among the most common visualizations used by chemists in both academic and industrial settings, where they serve as both representations of submicroscopic entities and tools that support social discourse. The ability to use words to communicate about features within NMR spectra is thus an essential…

This article highlights the multianalytical study of exuded liquid from an ancient Egyptian sealed alabaster vase by Master's students in an applied chemistry for cultural heritage course. Master students are introduced to the field of Archaeometry that see the collaboration of experts in different areas of research such as conservators, curators…

The experience of designing and teaching a lecture-based course about characterization techniques commonly used in solid state chemistry and materials science in an undergraduate institution is described. Among the techniques studied were the following: powder X-ray diffraction, infrared spectroscopy, Raman spectroscopy, scanning electron…

An undergraduate experiment combining synthesis, NMR analysis and mechanistic understanding is reported. The students perform an organocatalyzed cyclopropanation reaction of (E)-dec-2-enal and are then required to determine the diastereoselectivity and assign the relative configuration of each product using NMR spectroscopy.

The importance of utilizing spectroscopic techniques for unraveling structural and compositional changes in nonreacting and reacting systems is unquestionable. Nowadays, efforts are directed towards the introduction of relevant spectroscopic techniques to undergraduate students in order to prepare them for future careers in industry and academia,…

Two-dimensional nuclear magnetic resonance (2D NMR) techniques are regularly used for the determination of RNA structures. In an effort to introduce advanced level students who are generally not acquainted with or exposed to these techniques, this work, which has been designed as a practicum, utilizes a combination of 2D NMR techniques to help…

The free radical chlorination of an alkane experiment is often used in the undergraduate laboratory curriculum to introduce students to the free radical mechanism, substituent effects, intermediate stability, and the relative reactivity of radicals. In this experiment, students monochlorinate multiple alkanes and analyze the reaction mixture using…

An easily constructed and inexpensive polarimeter with an optical rotation angle resolution of about 0.5° is presented. It is made from small pieces of polarizing film, 2 LEDs, a protractor, and a few wires, all held in place with plastic interlocking toy bricks, such as Lego bricks. The instrument was used to demonstrate the optical rotation of…

The mirror neuron system has been argued to be a key brain system responsible for action understanding and imitation. Subsequently, mirror neuron system dysfunction has therefore been proposed to explain the social deficits manifested within autism spectrum condition, an approach referred to as the broken mirror hypothesis. Despite excitement…
