This research aims to examine the effect of integrating arts in a laboratory practice, concerning basic artistic stage, chemistry and art, dermocosmetics, and laboratory practice level dermocosmetics production, on the learning performance of students. The application process consisted of two stages, namely an experimental stage and an artistic…

Benchtop NMR spectrometers are now becoming more widely employed in university teaching laboratories. These low-field instruments are increasingly used in reaction monitoring and product purity applications. NMR spectra obtained using these spectrometers (40-80 MHz) tend to suffer from significant overlap of signals when compared to those obtained…

High voltage supplies are often used in physics classes for demonstrations and laboratory work. These devices deliver several thousand volts DC, while limiting the current to a safe level, typically under 5 mA. One issue with these power supplies is their expense, which means schools may not have one. Less expensive homemade units have been…

In this third and final manuscript from the Human Anatomy and Physiology Society (HAPS) 2022 Lab Survey we document the efforts of Human Anatomy and Physiology (A&P) educators in response to the COVID-19 global pandemic. Institutional, instructional, and student demographics, and laboratory activities and learning outcomes were the focus of…

Molecular photochemistry is an integral field in chemistry. Despite this, it is often difficult to demonstrate an effective hands-on experiment that offers a unique opportunity to students to observe photochemistry in action. Although simple laboratory experiments which use a UV-vis wavelength lamp do provide some photochemical information, the…

A laboratory experiment is described in which students carry out immobilization of the enzyme invertase via entrapment in alginate (Ca-alginate) and, accordingly, estimate values for kinetic constants and mass transfer coefficients. Immobilization of enzymes, or confinement thereof to a defined space with retention of most catalytic activity, is…

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…

This article describes a straightforward approach to deliver an enzyme assay and kinetics laboratory via online delivery methods in the time of COVID-19.

Space science education is an area of emerging importance in the 21st Century. Missions sponsored by the U.S. National Aeronautics and Space Administration (NASA) and programs facilitated through the NASA Space Science Education Consortium (NSSEC) offer unique opportunities to foster learner interest in space science as well as the broader field…

A recirculating water vacuum pump was constructed from inexpensive materials. The recirculating water vacuum pump has a smaller footprint compared to many commercial models and features a novel, 3D-printed water aspirator pump that also functions with a standard laboratory faucet connection. The performances of both the recirculating water vacuum…

Suzuki-Miyaura coupling reactions are well-known among the most versatile catalytic C-C bond formation reactions. Two different routes of C-C bond Suzuki-Miyaura coupling reactions for the undergraduate organic chemistry laboratory courses have been designed and explained. A two-step reaction involving a catalyst preparation as the first step and…

Laboratory classes are a central element of all biochemistry and molecular biology programs. These play a role in developing students' hands-on and technical skills and also offer much more. The design of laboratory classes depends on many factors including the programs the students are enrolled in, the level they are at, employment destinations,…

Nuclear magnetic resonance (NMR) spectroscopy is an indispensable technique in the organic chemistry laboratory for elucidation of molecular structure. Miniaturization of NMR technology has attracted attention and acceptance due to a considerable reduction in the cost to acquire and maintain the instrument. The advent of low-field, low-cost, and…

A bouncing rubber ball under a motion sensor is a classic of introductory physics labs. It is often used to measure the acceleration due to gravity, and can also demonstrate conservation of energy. By observing that the ball rises to a lower height upon each bounce, posing the question "What is the main source of energy loss?" and…

Chemical engineering students need to be prepared to make process safety decisions in industry. Through analysis of the decision-making process of senior chemical engineering students, we found students would rather be "better safe than sorry" and did not often acknowledge complexities associated with their decisions. Their decisions…
