This communication describes an updated experiment of peptide synthesis, involving determination of the loading capacity of a Fmoc-protected amino functionalized resin using UV-vis spectroscopy and a subsequent synthesis of a dipeptide in order to exemplify the experimental solid-phase synthesis procedure as an alternative technique in organic…

Structure--activity relationships are foundational concepts in biochemistry and drug design. Despite their importance, it can be difficult to create and execute laboratory activities that allow students to directly observe the interactions between small-molecule drugs and their biomolecular targets. Here, we report an activity that investigates…

Cycloadditions in combination with multicomponent reactions are among the most valuable synthetic tools used by organic chemists to construct cyclic and heterocyclic compounds in a straightforward way. Although cycloadditions, such as the Diels--Alder reaction, are mainly covered in basic and advanced organic courses for undergraduate students,…

Text-to-speech (TTS) technology is a common accommodation available for students with disabilities. Despite the ubiquitous nature of TTS, this technology has not been explored in laboratory settings for neurodiverse college students. This study explores the adaptability of laboratory accessible TTS technology (originally developed for blind/low…

This paper uses the questionnaire to evaluate the current status of laboratory safety perceptions, willingness, and efforts of first-year undergraduates at the School of Chemistry and Chemical Engineering, Tianjin University of Technology. The survey includes a sample size of 360 undergraduates covering four chemistry-related majors. The…

Low-dimensional materials especially graphene-based are of high interest to a broad community. One of the most fundamental aspects in the biomedical field is material characterization, which helps understand their property and tune for application. Though the existing teaching curricula are well standardized to include basic principles and…

Encouraging student engagement is a key aim in any educational setting, and allowing students the freedom to pursue their own methods of solving problems through independent experimentation has been shown to markedly improve this. In many contexts, however, allowing students this flexibility in their learning is hampered by constraints of the…

A chemical engineering student's knowledge of theory, experimental design, and real-world processes is tested and enforced in the Unit Operations laboratory courses. However, instructors are facing challenges of delivering high-quality, hands-on laboratory content with limited resources and increasingly large class sizes. Limited in-lab time is…

Education in biochemistry teaching laboratories focus primarily on applying biochemical techniques to understanding human disease, biochemistry, and biotechnology. With anthropogenic climate change, there is a renewed interest in quantifying biodiversity, especially with the use of molecular-based approaches such as DNA barcoding. This 3-week…

Shadows produced by sunlight reflected from convex surfaces can be very well defined. This article provides an explanation for this phenomenon as well as a demonstration/lab activity for students to investigate properties of shadows made from sunlight reflected by a curved surface.

In our first-semester introductory physics laboratory, we have an exercise on rotational dynamics. We have recently upgraded the equipment that we use in that exercise without changing the actual exercise. The new equipment has performed well so far, and we wanted to share what we did with others who may be looking for a relatively inexpensive way…

An operationally simple, reliable synthesis of ethynylated acenes suitable for an upper-division undergraduate organic chemistry laboratory course has been developed. This experiment requires students to synthesize two acene derivatives and can be completed in 6-8 laboratory sessions (3 h each); a shorter experiment could be realized in the…

Ultraviolet (UV)-visible (Vis) spectroscopy is widely used in all modern laboratories as a routine method of analysis. The monitoring of chemical reactions in an aqueous solution involving a gas product is a demanding task but particularly for oscillatory reactions which are obtainable in a narrow concentration range. In this work, the…

This work aims to describe the socio-technical network of a Chemistry laboratory in the school "Professora Maria do Rosário Castaldi", a State Center for Professional Education in the city of Londrina, Brazil, taking the translation theories proposed by Bruno Latour as motivation. The observation data were either recorded in audio or…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] This manuscript presents a case study of an introductory physics student who, during the remote learning conditions imposed during the COVID-19 pandemic, found inspiration within a new, open-inquiry, project-based, laboratory curriculum…
