Fractal structure of laser-irradiated porous carbon material

The fractal structure of porous carbon material doped with manganese before and after laser irradiation was investigated by the method of small-angle X-ray scattering. The type of fractal aggregate and the value of its fractal dimension D, which is 1.4-1.5 for non-irradiated samples of the first level of fractal aggregation and 2.7 for irradiated samples of the second level of fractal aggregation, were determined.
