ALT SCIENTISTS JUST CREATED A MATERIAL THAT BREAKS THE RULES OF HEAT What if you could make a material that is **extremely hard to heat up—but still remarkably strong?** Researchers at **North Carolina State University** engineered a layered material that does something unusual: it blocks heat almost like an advanced aerogel, while remaining mechanically rigid. At room temperature, it conducts heat at only about **0.04 watts per meter-kelvin**—among the lowest reported for a dense, nonporous solid. Yet its stiffness reaches about **7.7 gigapascals**, far stronger than many plastics, foams and aerogels. The secret lies between its layers. Organic molecules were engineered into a hybrid perovskite structure, making it difficult for the tiny vibrations that carry heat to travel through the material. Even more interesting, the material can be deposited as a **thin film over large areas**, potentially opening doors for advanced thermal insulation and electronics.
