The color of smoke coming out from chimneys can vary greatly based on its source and how it is produced. For instance, small coal or biomass stoves typically release dense, black smoke, while power generation plants produce lighter-colored plumes of smoke.
Proton exchange membrane fuel cells (PEMFCs) are power cells that can transform the chemical energy produced during the electrochemical reaction between hydrogen and oxygen into electrical energy. While these cells could be highly promising energy solutions, most of...
In recent years, engineers worldwide have been working to create alternative and sustainable energy solutions, such as solar cells. Solar cells made of perovskites, a class of semiconductors with a characteristic structure and advantageous properties, are among the...
The efficient and large-scale conversion of carbon dioxide into fuels or other valuable substances could help to address the current energy crisis and mitigate the effects of global warming. One of the most effective approaches for converting CO2 into other...
The oxygen evolution reaction (OER) is a chemical reaction that enables the generation of oxygen gas. This reaction is crucial for producing fuels through water splitting or through the electroreduction of CO2.
Over the past few years, engineers have created increasingly advanced technologies to produce and store energy more sustainably. Solar cells made of organic molecules or polymers are among the most promising sustainable energy solutions, as they are typically thin,...
The separation of light hydrocarbon mixtures is among the most important petrochemical and industrial processes. This process is currently regarded as highly energy intensive, as it has so far been carried out using conventional techniques, such as cryogenic...
Past research suggests that climate change and energy systems have a bidirectional relationship. In other words, just like emissions from energy systems can fuel climate change, climate change could also expose the vulnerabilities or shortcomings of energy systems.
In recent years, engineers have created a variety of solar technologies using different types of materials. These include solar cells based on cadmium telluride (CdTe), a stable crystalline semiconducting compound comprised of cadmium and tellurium.
Lithium-metal batteries (LMBs), an emerging type of rechargeable lithium-based batteries made of solid-state metal instead of lithium-ions, are among the most promising high-energy-density rechargeable battery technologies. Although they have some advantageous...
