A chemistry laboratory experiment is described to introduce undergraduate college students to membrane separation technology. This experiment combines a simple nanowire membrane fabrication and visually indicated molecule separation. The membrane is produced via coprecipitation synthesis followed by a filtration assembly process, which can be…

A new teaching resource comprised of raw X-ray diffraction data sets from crystallography experiments has been compiled. The aim of this resource is to provide a tool with which to plug the teaching gap between crystals and chemical structures present at various levels of education, as well as providing examples for early stage researchers and…

The COVID-19 pandemic affected a large range of in-person education activities in Colombia. This created great limitations in academic performance for students with reduced access to communication technologies and deepened the educational gaps in the country. This was particularly true for sciences such as biochemistry. In Colombia, molecular…

Nanoscience and technology research offer exciting avenues to modernize undergraduate-level General Chemistry curricula. In particular, spherical nucleic acid (SNA) nanoconjugates, which behave as "programmable atom equivalents" (PAEs) in the context of colloidal crystals, are one system that one can use to reinforce foundational…

This article highlights some of the challenges in explaining simple substituent effects on keto-enol equilibria, particularly to an undergraduate audience. Quantum-chemical calculations were performed to identify the role of intramolecular hydrogen bonding, inductive effects due to electron-withdrawing groups, and cross-conjugation on the…

The rise of virtual and online education in recent years has led to the development and popularization of many online tools, notably three-dimensional (3D) models and augmented reality (AR), for visualizing various structures in chemical sciences. The majority of the developed tools focus on either small molecules or biological systems, as…

The inductive effect is one of the very important concepts of electronic effects in organic chemistry. In traditional teaching methods, only the origin, transmission mode, and decay of the inductive effect are introduced briefly, which is not conducive to students' complete understanding of the inductive effect. This work developed a new method to…

Nanotechnology has made a huge impact on science, technology, and society. At the same time, educational institutions at all levels have recognized its relevance and introduced courses that aim at familiarizing their students with the basic concepts of nanotechnology. While the importance of teaching nanotechnology, the contents of such courses,…

In the violin, the fundamental air cavity mode (the A0 mode) is associated with the sound radiated by the f-holes. The dependences of the sound velocity of the A0 frequency on gaseous temperature and mass were investigated. It was found that the frequency of the A0 mode changed, depending on the molecular weight and the temperature of the gas…

Teaching chemistry and biology students about biologics design remains challenging despite its increasing importance in pharmaceutical development. Monoclonal antibodies, commonly called mAbs, are the most popular biologics. They have been developed into drugs to treat various diseases in the past decades. Multiple challenges exist for designing…

Many approaches to teaching Newman projections and conformational manipulation rely on lecturing using only two-dimensional representations. While molecular models are recognized as useful learning tools, students are often left to figure out how to use them during the initial learning process. The availability of basic online molecular models…

The field of biosensors is a burgeoning area of research and employs a large number of chemistry graduates. The impact of strip tests in detecting coronavirus was palpable during the recent COVID-19 pandemic and will further drive the biosensor industry. Despite their common usage, a coherent introduction to the basics of sensing remains missing…

The contemporary Human activity utilizes huge volumes of digital data to solve efficiently multiple socio-economic, scientific and technical problems. Now the big data analysis is mainly oriented to the socioeconomic sphere with a goal to lift the profit. The science and technology to penetrate deeper in the nature of objects and systems under…

Models were prepared by 3D printing that can be used to demonstrate the operations required for the study of molecular symmetry. The models were designed to emphasize the order and locations of rotation axes and to clearly illustrate the more abstract reflection and improper rotation axes. The models were well-received by students in a course on…

A thorough appreciation of the three-dimensional arrangement of atoms in molecules is crucial for new students of chemistry and critical to students continuing their studies in chemistry. We discuss current use of molecular models in education and investigate a variety of techniques used over the years to introduce students to atomic orbitals.…
