Aqueous dispersions of soot and other carbon materials, prepared in a manner similar to that used for preparing traditional Japanese ink, were developed as teaching materials for colloid chemistry. The protective colloid formed by the addition of glue is an interesting teaching material that allows visual understanding of various colloidal…

Enzyme-like catalysis is the use of artificial catalysts to catalyze chemical reactions, which has the characteristics of enzymatic catalysis, such as high selectivity, high efficiency, and mild reaction conditions. In recent years, 2D materials, thickness ranging from a single to several atomic layers, have become a hot research topic in the…

A 2 min film clip from the classic movie "Son of Frankenstein" is a surprisingly good illustration of, and introduction to, the scientific method as traditionally formulated. It may be useful in introducing the topic to a large variety of audiences. The text includes a description of the clip's content, questions to elicit student…

Electrochromism encompasses reversible changes of material's optical properties (color, opacity) under the influence of an external electric current or applied voltage. The effect has been known for decades, but its importance continues to grow due to the rapid development of smart systems and the accompanying demand to build devices that consume…

Key components of any experiential learning module are the resources students use to learn. These typically include laboratory equipment, handouts, and instructional material in the form of videos or standard operating procedures (SOPs). Their design and implementation require careful thought to ensure that students learn in an effective and…

Radioactive isotopes are an essential part of everyday life and an expanding area of research in the fields of medicine, catalysis, and energy. Here, we describe an educational activity that introduces the concept of radioactive decay and the corresponding benefits, risks, and safe handling strategies. Specifically, we have developed an…

The periodic table is a fundamental tool used in chemistry classes that allows students to systematically understand different types of elements and their physical and chemical properties. While many textbooks emphasize the historical process of classifying substances, they often superficially elucidate the achievements of chemists such as Dmitry…

Assumptions about the feasibility of teaching chemistry laboratories online have been challenged by the ongoing COVID-19 pandemic. We argue that, despite the fact that pandemic social distancing restrictions will be eventually eliminated, the development of quality digital laboratory resources must continue to receive attention from the chemistry…

This work presents a homemade multirole 3D-printed modular spectrometer(MPMS), which can be easily assembled like bricks and expanded with several modules to measure different types of spectra, such as UV-vis absorption, fluorescence emission, flame emission/absorption, glow discharge, and even Raman spectra. The spectrometer is designed to be…

In all fields of chemistry, it has become essential to use quantum chemical calculations and machine learning for explaining and predicting chemical phenomena. However, it is challenging to apply textbook knowledge to practical research. In this study, we developed teaching material based on computational chemistry to promote the integration of…

Instrumentation plays a critical, ubiquitous role in modern chemistry. The undergraduate chemistry curriculum must therefore cultivate students' ability to investigate chemical phenomena via relevant instruments. The instructional laboratory serves as the primary context in which undergraduates learn about instrumentation, where use of instruments…

Real-world safety case studies provide concrete examples of episodes that can be both instructive and memorable for students. We describe here a framework for teaching safety case studies using the RAMP risk management approach. Structured templates guide students to Recognize the hazards present, Assess the associated risks, and consider what…

The alternative conceptions that students hold put a brake on subsequent meaningful learning, and therefore, the identification of these wrong ideas is crucial for effective teaching and academic success. Undergraduate STEM students often perceive Chemical Thermodynamics as a difficult subject, in which entropy has been pointed out as a threshold…

Schools and universities had to quickly adapt to a distance-learning model when the COVID-19 virus became a worldwide pandemic. In response, teachers found alternative ways to deliver course content and also interact with their students one-on-one to help them learn the material. We present here an inexpensive mirror mount for students to use on…

Single-type, 8-fold-grooved, commercially accessible interlocking disks (ILDs) have been used for modeling of complex polyhedral and reticular topologies with relevance to inorganic and hybrid materials. The assembly of complex topologies relies on the preparation of secondary building units (SBUs), which exhibit different connectivity than that…
