Phase-change materials represent cutting-edge technology in both Brazil and the USA for sustainable energy solutions. In Brazil, PCMs are increasingly researched for tropical climate applications where thermal regulation is critical. In the USA, they are extensively used in aerospace, building construction, and textile industries. This is primarily technical/scientific terminology with limited colloquial usage.
