An international team of researchers, led by Drexel University, has found that a thin coating of MXene—a type of two-dimensional nanomaterial discovered and studied at Drexel for more than a decade—could enhance a material's ability to trap or shed heat. The discovery, which is tied to MXene's ability to regulate the passage of ambient infrared radiation, could lead to advances in thermal clothing, heating elements and new materials for radiative heating and cooling.
