Fractal distribution in barium sulphate makes better paint

Fractal distribution of particle size helps white paint to be more reflective:

Quote
Third, the pigment particles were of varied size. The amount of light scattered by a particle depends on its size, so using a range scatters more of the light spectrum from the sun. Ruan’s lab had assessed more than 100 different materials and tested about 50 formulations for each of the most promising. Their previous whitest paint used calcium carbonate – chalk – and reflected 95.5% sunlight.

Took me a while to realize but this refers to the roughness over different scales, that's definitely fractal.
