The distinction between pressure in a liquid and in a gas is often treated in a cursory way, or not treated at all, even in university level textbooks. Most texts fail to point out the relation between pressure and density in a gas as compared to pressure in a--virtually incompressible--liquid. In many instances this also results in a dismissive…

The use of the thermodynamic formalism in the investigation of biochemical reactions constitutes one of the key analysis in bioenergetics, and the first step in such analysis is the selection of the adequate reference state. For biochemistry majors, thermodynamic analysis based on the chemical reference state is used in Physical Chemistry courses,…

In recent years, solar-powered photocatalytic water splitting for hydrogen production has drawn great attention as a method to supply clean energy and reduce environmental pollution. This approach, driven by solar energy to synthesize hydrogen gas, is completely renewable and can be used to power hydrogen fuel cells to effectively solve the global…

In this paper, drawing on an extensive research project across three countries (VET Africa 4.0 Collective 2023), we produce an emerging argument that it is necessary to rethink and reframe VET logics and approaches in a warming future dominated by informality and mass unemployment. Currently, neither the formal VET college or workplace are…

Various experiments on vibrating gas columns and on frequency measurements with glasses and pipes have been presented in recent years in the "iPhysicsLabs" column. The determination of the sound velocity in different gases by measuring the sound running time has also already been proposed in an earlier paper. This article now adds…

This study presents a low-cost Arduino-based gas chromatography system that is suitable for teaching analytical chemistry in an undergraduate laboratory. The gas chromatography system is built with commonly available materials with a total cost less than $100. A Python code is also provided as a user interface that will record data and display the…

Trace metals when present in crude oil or fuels are of economic significance in refining and to the combustion engines that use them. Herein, we develop a laboratory activity that trains students on how to analyze crude oil samples for ash and trace metal content while giving them the opportunity to acquire skills needed as a quality control…

The purpose of this qualitative descriptive study was to explore how petroleum industry technicians and technologists describe their experience with and the value they place on online education as professional development in Bonny Island, Southern Nigeria. The social cognitive career theory was used as the theoretical foundation for this study.…

Organizing undergraduates in chemistry, energy engineering, and chemical engineering specialties to participate in an energy transformation experiment can encourage them to think about the impact of human activities on nature and stimulate them to learn more about the topic. This laboratory experiment demonstrates a general approach to the…

The study aims to present how to apply a STEM activity in which physical computing principles and computational thinking processes are used as a differentiation practice to be used in the education of gifted students. In the activity, the students designed smart packaging that will provide healthy long-term storage of foods to solve the greenhouse…

Integrating service learning with undergraduate research, the student biodiesel project converted all waste vegetable oil (WVO) from campus dining centers into a sustainable biofuel used by campus vehicles, allowing half of the campus diesel energy needs to be met by a material (WVO) that was formerly a waste. Biodiesel reduced air pollution from…

In this inquiry, I explore, expose, and extrapolate upon sociopolitical and environmental absurdism as an environmental academic and educator based in Alberta, Canada--a well-known, and somewhat infamous, centre of oil and gas production and energy development in general. Moving beyond Alberta as a catalytic example, I introduce and discuss…

It is not only worth talking about the chances of survival in the fight against emerging environmental and socio-economic threats, but it is necessary to use all possible means to influence public awareness. It is awareness that shapes our attitudes and literacy. The core of these tools is cross-sectoral place-based education. This raises the…

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…

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…
