In recent years, the food industry has been undergoing major changes driven by new social and environmental demands. Nowadays, biodegradable packaging is perceived as the most feasible alternative for food packaging. Great efforts are being devoted to the development of new materials from agro-industrial wastes and byproducts that are opening new…

The implementation of environmentally friendly, solvent-free mechanochemical synthesis in an undergraduate chemistry teaching laboratory is described. As a model reaction, the experiment addresses the catalytic mechanochemical synthesis of a small library of sulfonylureas, including a known active pharmaceutical ingredient, tolbutamide. The…

This study was conducted to determine the effectiveness of virtual laboratory based on semi second life (s-SL) on higher order thinking skills of general senior secondary school in chemistry learning process. The research design was adopted posttest only design approach to a quasi-experimental. This study was conducted in the one of public general…

Laboratory safety is a vital part of a chemical education and can be incorporated into courses throughout the chemistry curriculum. Discussions of laboratory safety can serve as an introduction to the important field of green chemistry. Exposure to this field can better prepare students for safer and more sustainable laboratory practices in…

During the coronavirus pandemic, there have been significant challenges in the remote teaching and demonstration of experiments, especially those that require laboratory testing equipment. With a desire to give students a feel for our materials laboratory on open days and allow them to gain a deeper understanding of what materials science and…

Here, we propose the use of magnetic levitation (MagLev) device, as a simple, cheap, and portable experimental technique to measure the density of diamagnetic materials in laboratory settings. We highlight the basics of a standard MagLev system for measuring the density of unknown diamagnetic materials/objects using permanent magnets, paramagnetic…

The gross anatomy dissection course is considered to be one of the most important subjects in medical school. Advancing technology facilitates the production of e-learning material that can improve the learning of topographic anatomy during the course. The purpose of this study was to examine a locally produced audiovisual dissection manual's…

This paper demonstrates the use of a smartphone as a low-cost multi-channel optical fibre spectrophotometer suitable for physics laboratory classes. A custom-designed cradle and structure support were fabricated using 3D printing. The plastic optical fibres were arranged and inserted into the hole of the cradle to guide the light to the rear…

An experiment was developed for a first year food chemistry laboratory course that demonstrates the influence of several aspects of polysacharide structure on the rate of amylase catalyzed hydrolysis. The experiment would be particularly well-suited to a first year chemistry course that was targeted at nonchemistry majors, such as health related…

Inorganic Chemistry teaches students the concept that modifications to ligand structures, especially the donor properties, can have a drastic impact on the reactivity and stability of the metal complexes. Experiments described here reinforce this concept through the investigation of two tetradentate ligands derived from…

In general, undergraduate experimental physics laboratories do not usually have experiments designed to address rolling friction and to measure the value of the rolling friction coefficient. This work explores an experiment, which has the potential to arouse students' curiosity about rolling friction by addressing a counterintuitive aspect of the…

Nuclear magnetic resonance (NMR) spectroscopy has become a cornerstone tool for studying a variety of molecular features in advanced chemistry laboratories. In this experiment, students prepare a pyrrole-[beta]-amide via a one-pot, three-step synthesis and use NMR spectroscopy to confirm its molecular structure. In addition, variable temperature…

A contemporary undergraduate laboratory experiment incorporating parallel microscale experimentation was developed for the well-defined palladium catalyzed Suzuki-Miyaura cross coupling of 4-fluorophenylboronic acid with both 4-chloro- and 4-bromoanisole using 11 diverse phosphine ligands and one ligandless control. This laboratory introduces…

Students are introduced to the concepts of static electricity at a school level and an under-graduate level. In this paper, we present an inexpensive and portable device that can be used to study the static electricity and verify polarity of the electric charge on materials in a triboelectric series. This device is developed at the Science…

Chemical safety is a discipline that cuts across all other chemical disciplines and also impacts other laboratory sciences. It is an essential part of chemistry and continues to evolve with the science it supports. This paper provides a short background about ACS's growing involvement with chemical safety education that stems from support from ACS…
