Boiling material
Make no mistake: this might look like the caramelised crust of a crème brûlée, but it is actually a sample of plastic decomposing under the effect of heat. More precisely, the image shows the process of nucleation in which the gases produced by the combustion of a polymer collect in bubbles that then rise to the surface of the material, where they eventually burst. By modelling this phenomenon in underventilated environments such as high-energy performance buildings, scientists hope to develop fire-fighting strategies in confined spaces that are both more effective and less hazardous for firefighters.
