Ideally the microwave reactions can be driven by green energy, in which case the system could help reduce carbon dioxide by converting it into other useful chemicals. Credit: 2025 Kishimoto et al. CC-BY-ND Some industrial processes used to create useful chemicals require heat, but heating methods are often inefficient, partly because they heat a greater volume of space than they really need to. Researchers, including those from the University of Tokyo, devised a way to limit heating to the speci...
