E-Mail IMAGE: To realize a hydrogen fuel-based future, it is necessary to be able to produce it efficiently in an eco-friendly manner view more Credit: Incheon National University To combat climate change, shifting from fossil fuels to clean and sustainable energy sources is imperative. A popular candidate in this regard is hydrogen, an eco-friendly fuel that produces only water when used. However, the efficient methods of hydrogen production are usually not eco-friendly. The eco-friendly alternative of splitting water with sunlight to produce hydrogen is inefficient and suffers from low stability of the photocatalyst (material that facilitates chemical reactions by absorbing light). How does one address the issue of developing a stable and efficient photocatalyst? ....

E-Mail IMAGE: Progress in fuel cell technology will help us greatly reduce our use of fossil fuels to generate electricity, leading to less air pollution view more Credit: Chris LeBoutillier on Pexels Many efforts are being made worldwide to replace fossil fuels with greener alternatives. Hydrogen (H 2) is a promising option that is currently in the spotlight; it can be used to generate electricity in fuel cells with water generated as the only byproduct. However, the technology is not quite ready for commercialization because proton-exchange membrane fuel cells, the most widely studied type, suffer from high cost and stability issues. ....
E-Mail IMAGE: Plastic waste can contaminate water supply as it breaks down into microplastics and its additives leach out. These additives sometimes contain harmful chemicals which accumulate in the environment and in. view more Credit: Seung-Kyu Kim from Incheon National University Plastic pollution has been at the center of environmental debate for decades. While it is well-known that plastic in the environment can break down into microplastics, be ingested by humans and other organisms, transfer up the food chain, and cause harm, this is only one part of the picture. Plastics are almost always enriched with additives, which makes them easier to process, more resistant, or more performant. This poses a second problem: when the polymer material is left in an environment for long durations, these additives can easily leach out and contaminate the environment. ....
