Air pollution is a major environmental challenge of this century. In a recent Journal of Environmental Sciences review paper, ...

Scientists in the United States have proposed to use a thermochemical energy storage (TCES) technique that stores energy in chemical bonds to recover the heat produced during air compression ...

Researchers at Imperial College London claim to have developed a stable alkaline-based hybrid polysulfide-air (PSA) redox flow battery (RFB) that can reduce “crossover” issues via a new ...

Hydrogen fuel cells, which power some electric cars, pack far more energy per weight than lithium-ion batteries. The devices also show promise for decarbonizing aviation, shipping, and trucking. But ...

One sweaty, huffing, exercising person emits as many chemicals from their body as up to five sedentary people, according to a new study. And notably, those human emissions, including amino acids from ...
