Link 18-Black Matter Diffusion
everywere , on earth and in interstellar spaces.
The black material is inorganic or organic. Black show electrical activity or property. Black is generally in the amorphous state but beautiful black crystals are formed from the semiconductor cadmium selenide, the super conductor perovskite YBa2Cu3O6.5, the black salt of ethylenedioxyethylenedithiotetrathia fulvalene t-(EDOEDTTTF)2 (AuI2)1 (AuI2) y.
Minerals,salts, oxides, sulphides, graphite, coal, oil, oil shales, guano, tars, bitumen, smokes, pollutants of sea, lakes, rivers, fullerenes, cosmoids, meteorites, volcanic stone,
synthetic (BSM) :
Acetylene- black, pyrrole-black, tiophene-black, benzene-black, indole-black, quinoline-black , aniline-black , thiofulvalene-black. Fe-porphyrin salts, DHI-black, DHICA-black et cetera….
Organic natural ( BCM ) :
Eumelanins (BCM), pheomelanins (Link 14), allomelanins, skin-melanin, hair-melanin, fur-melanin, choroid melanin, eyes-melanin, scales-melanin, feathers-melanin, cuticle -melanin, liver-melanin, Substantia nigra-melanin, Locus coeruleus-melanin, melanoma-melanin, plant-melanins, lignin-melanin (ebony), flower-melanin, seed-melanin, microrganism-melanin, mold-melanin, soil-melanin (humic acids) are all amorphous with exception of some pheochromes.
Many other natural compounds or derivatives are black:
biline derivatives, metalloporphyrins, ommins, pterins, cyanins, alizarine salts, zoochromes.
All these compounds are close to melanins sharing the radical-polarone system of acetylene-black.
For some materials the collocation to one or other class (inorganic or organic) may result difficult.
