Aerogel, Nanotechnology, Optics, Mathematics.
silica aerogel that has particle sizes of around 50 nanometers: I = Scattering Intensity. I₀ = Intensity of Light. R = The distance the light is taking to scatter in the aerogel. λ = The wavelength of the light entering the aerogel (mostly sunlight) d = Diameter of the light scattering in the
