Computational and atmospheric chemistry are two important branches of contemporary chemistry. With the present topical nature of climate change and global warming, it is more crucial than ever that students are aware of and exposed to atmospheric chemistry, with an emphasis on how modeling may aid in understanding how atmospherically relevant…

In this paper I describe an interactive Gauss's law computer simulation using the GlowScript programming environment. The simulation calculates a point charge's electric field at locations on the surface of a Gaussian cube and displays the electric field in GlowScript's 3D graphics window. The point charge can be moved, and the electric field…

The COVID-19 pandemic forced the adoption of online laboratories. The present article discusses the virtual laboratories used by students. The questions posed by students provided targeted teaching opportunities.

A qualitative sugar identification laboratory was adapted from a hands-on experiment to a virtual "choose your own adventure" experience where students select virtual experiments to conduct on samples of known and unknown carbohydrates. Students select positive and negative controls for each qualitative test and compare results from the…

Despite the growing importance of nanomaterials in numerous industries, most undergraduate chemistry students are unlikely to encounter characterization techniques common in the field during their education. Scanning electron microscopy (SEM) is a common technique for materials characterization widely used in careers chemistry students are likely…

Virtual labs have proven to be very versatile and valuable for providing realistic experience for students in STE (Science, Technology, and Engineering) fields. As we progress from delivery of instructional material from classroom to the Internet, there is need to develop laboratory exercises to supplement the theoretical lessons. A Web-based…

An experiment for the undergraduate physical chemistry laboratory is described in which the Raman spectrum of liquid "para"-difluorobenzene is recorded and assigned. A density functional theory (DFT) calculation of the 30 normal modes of the molecule is undertaken using computational chemistry software. Students use group theory to…

Flow cytometry has become an important tool in the fields of veterinary, medicine, and biological sciences in general. However, in the introductory and even in advanced university degree courses, students do not have many opportunities to be in contact with this type of technology. This situation motivated us to design a simple and inexpensive…

Over the past half century, computational chemistry has evolved from a niche field to a ubiquitous pillar of modern chemical research. Driven by the increased demand for computational chemistry in research settings, the undergraduate curriculum has evolved alongside to ensure that students are well-equipped for modern research. Toward this end,…

The introduction of electric circuit simulation software for undergraduate students in a general physics course is proposed in order to contribute to the constructive learning of electric circuit theory. This work focuses on the lab exercises based on dc, transient and ac analysis in electric circuits found in introductory physics courses, and…

Enzyme-linked immunosorbent assay (ELISA) is a valuable tool in various chemical and biological fields for investigating the presence and quantity of proteins of interest in given samples. The high importance of the assay makes it widely used in biological research and hence a crucial skill to master for up-and-coming scientists. A major…

Coronavirus (COVID-19) disease is an emerging situation that brought challenges to all sectors, including academia and research. Undergraduate and postgraduate students in biochemistry and molecular biology have been affected significantly due to the recent laboratory closures. Experiments have been suspended for long causing extreme stress to the…

Capillary electrophoresis is a powerful separation tool with a wide range of analytes for diverse applications and is compatible with various detection methods. While some more established separation techniques like gas or liquid chromatography are utilized heavily in analytical chemistry laboratory courses, newer commercial capillary…

We designed and tested a 3D motion tracking system which displays acquired and derived data using augmented reality. This setup, based on a virtual reality headset and its controllers, is a relatively low-cost, high-precision, six degrees of freedom, high-speed, multiple-objects tracking device. This apparatus proves to be a very high-quality…

Eleven different laboratory experiments were designed and executed throughout a semester to provide a meaningful research experience for 23 undergraduate biochemistry majors at UTSA. The topic of the semester was based on the idea of exploring new aspects to enhance our understanding of how the human body uses cytochrome P450 enzymes to metabolize…
