Energy conversion devices such as fuel cells, metal-air batteries, and electrolyzers have been envisaged as possible solutions for cutting down the continuous accumulation of greenhouse gases resulting from the combustion of fossil fuel. The bottleneck reaction for these devices is the oxygen reduction reaction (ORR) occurring at the cathode. The…

A rocket must carry the fuel it expels in order to accelerate its structure and payload. The rocket equation relates the change in speed to the fuel mass expelled. To launch a spacecraft into Earth orbit requires a multi-stage rocket, since otherwise the mass of fuel required would be prohibitive. While the details vary among historical and…

A laboratory experiment was designed to provide students with an introduction to byproduct valorization by producing an analogue of biodiesel (fatty acid ethyl esters, FAEE) via lipid extraction and subsequent transesterification from spent coffee grounds (SCG). Valorization is the process of upgrading underutilized or discarded wastes or…

Calorimetry is a central concept in the first semester general chemistry curriculum, and constant pressure (coffee-cup) calorimetry is a common experiment in the laboratory. However, constant volume (bomb) calorimetry is traditionally reserved for the physical chemistry laboratory. This article describes the advantages of incorporating bomb…

At the end of 2022, there were 2439 coal-fired power plants operating around the world, and over 7000 active coal mines (Global Energy Monitor, 2022). Coal burning was the largest source of greenhouse gases that impact climate change, and coal mining caused extensive environmental damage (US Energy and Information Administration, 2022). Decisions…

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,…

Purpose: Many institutions of higher education have committed to carbon neutrality. Given this goal, the main economic issue is minimizing cost. As for society as a whole, dominant decarbonization strategies are renewable electricity generation, electrification of end uses and energy efficiency. The purpose of this paper is to describe the optimum…

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…

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…

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…

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…

Climate change is real and accelerating. It requires an urgent response that focuses all the strategies and tactics necessary to stabilize the Earth's temperature regime. According to Thomas Jorling, the objective to guide research, development and implementation is straightforward: Achieve an all-electric economy. Simply put, all sectors of…

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…

While deep disciplinary knowledge will be required to develop next-generation clean energy technologies, the skills to work across disciplines and with diverse stakeholders will also be required. Providing authentic and explicit opportunities for graduate students in science, technology, engineering, and math (STEM) to engage in the broader…
