"Discovery of an Exception to a 200-Year-Old Law of Heat Transfer"
Originally Published 1 year ago — by Phys.org
Researchers at the University of Massachusetts Amherst have discovered an exception to Fourier's Law, a 200-year-old scientific law governing heat transfer. Their study, published in the Proceedings of the National Academy of Sciences, reveals that pure electromagnetic radiation plays a role in heat diffusion through common materials like plastics and glasses, challenging the traditional understanding of heat transmission. The team's findings suggest that translucent materials allow energy to radiate internally, interacting with structural imperfections and becoming secondary heat sources, expanding our understanding of heat transmission and offering new strategies for designing heat circuits.
