3. Ultrahydrophobicity - Wikipedia

   en.wikipedia.org/wiki/Ultrahydrophobicity

   By coating an already transparent surface with nano-silica with about 1 wt%, droplet contact angles can be raised up to 168° with a 12° sliding angle. An efficient routine has been reported for making linear low-density polyethylene superhydrophobic and thus self-cleaning; [59] 99% of dirt deposited on such a surface is easily washed away.

   Index-matching material. In optics, an index-matching material is a substance, usually a liquid, cement (adhesive), or gel, which has an index of refraction that closely approximates that of another object (such as a lens, material, fiber-optic, etc.). When two substances with the same index are in contact, light passes from one to the other ...

8. Red pigments - Wikipedia

   en.wikipedia.org/wiki/Red_pigments

   Red pigments are materials, usually made from minerals, used to create the red colors in painting and other arts.
