Protein PEGylation refers to the covalent binding of polyethylene glycol (PEG) moieties to a protein and has been increasingly applied, mainly in the biopharmaceutical industry. This technique may increase bioavailability and stability by decreasing immunogenicity and proteolytic attack. Given the industrial interest and the relevance of this…

A new method to determine a ternary phase diagram of benzene-acetic acid-water system is provided to upper-division undergraduate students. The partially miscible liquid phase region can be accurately constructed using isothermal titration microcalorimetry (ITC). Compared with the traditional visual method, ITC can provide precise data and more…

A laboratory class was developed and evaluated to illustrate the synthesis of metal nanoclusters (NCs) and to explain their photoluminescence properties for the case of silver. The described experiment employs a synthetic protocol that consists of two sequential phases in a single reaction pot: the reduction of silver ions into plasmonic silver…

When Mentos candies are dropped into a bottle of Diet Coke, a foamy fountain jets out of the beverage container. It has previously been argued that ingredients found in Mentos candies significantly enhance this fountaining effect. Other previous work has demonstrated that the kinetics of foam production can be quantitatively monitored using a…

Students tend to think of their science courses as isolated and unrelated to each other, making it difficult for them to see connections across disciplines. In addition, many existing science assessments target rote memorization and algorithmic problem-solving skills. Here, we describe the development, implementation, and evaluation of an activity…

Moral ethic prevails in the science and education of chemistry. These issues are unique to chemistry and arise from between the theoretical and the practical behavior in laboratory. The study reported in the paper investigated the impact of personal moral philosophies on the safety practices of students in chemistry and related majors. The results…

This paper describes the course outline for a three credit hour nonlaboratory course in Environmental Health Chemistry which was taught from 1981 until 2008 at the State University of New York College at Oneonta. The purpose of this paper is to share the lecture outline in the hopes that it might be useful to others who are preparing to teach…

In 2015, "NFPA 45, Standard on Fire Protection for Laboratories Using Chemicals," from the National Fire Protection Association (NFPA) was updated to include language requiring educators to perform a documented risk assessment when conducting demonstrations in K-12 classrooms. Additionally, in the past five years numerous organizations…

The Americans with Disabilities Act allows a student with a disability to bring a service dog into any facility where the public is allowed, including academic teaching and research laboratories. However, the presence of the service dog does have an impact on the safety of the student, the service dog, and others in the laboratory. This article…

One of the most general aims of universities is to respond to the requirements of society. Health and safety are the most important aspects of professional work and play an important role in universities, as there, future professionals are trained for their future professional life. Scientific and technical degrees require adaptation to this…

Developing strong safety cultures in academic institutions requires that students at all levels be educated by faculty in chemical safety. Yet chemical safety education is missing from the chemistry curriculum. This article considers a report of numerous injuries from incidents from using flammable chemicals in demonstrations as evidence that…

Lampworking is a valuable skill for students in Chemistry and others in science, technology, engineering, and math (STEM) related fields. The activity described here provides instructors the resources to both learn and teach the fundamentals of lampworking. Soft glass, which can be shaped and fused with a Bunsen burner, is used to improve the…

Space-related activities remain a fertile environment for classroom applications of chemistry through both traditional lecture styles and through collaborative learning projects. With the resurgence of lunar exploration and the expansion of the commercial space sector, serious scholarship, planning, and resources have been focused on extracting…

The practical two-step synthesis of 1-phenylthiourea is reported here as an undergraduate experiment for the organic synthesis laboratory. The reactions involved in 1-phenylthiourea preparation are very useful didactic examples to illustrate concepts relating to carbonyl substitution and addition, the effect of pH on solubility of organic…

It is essential to develop a safety culture with the participation of university teachers and students in actions and studies that can contribute to safer and more sustainable practices in academic laboratories. The present work analyzes the potential of a training program to raise awareness and establish environmental education and green…
