Soot in very low concentrations is capable of darkening surfaces or making particle agglomerates, such as those from ventilation systems, appear black. Soot is the primary cause of "ghosting", the discoloration of walls and ceilings or walls and flooring where they meet.
Black carbon is in the air and circulates the globe. Black carbon travels along wind currents from Asian cities and accumulates over the Tibetan Plateau and Himalayan foothills. Black carbon (BC) is the light-absorbing refractory form of elemental carbon remaining after pyrolysis (e.g., charcoal) or produced by incomplete combustion (e.g., soot).
Susuwatari (Japanese: ススワタリ, 煤渡り; "wandering soot"), also called Makkuro kurosuke (まっくろくろすけ; "makkuro" meaning "pitch black", "kuro" meaning "black" and "-suke" being a common ending for male names), is the name of a fictitious sprite that was devised by Hayao Miyazaki and Studio Ghibli, known from the famous anime-productions My Neighbor Totoro (1988) and ...
Black soot absorbs thermal radiation very well; it has an emissivity as large as 0.97, and hence soot is a fair approximation to an ideal black body. [ 21 ] [ 22 ] With the exception of bare, polished metals, the appearance of a surface to the eye is not a good guide to emissivities near room temperature.
Carbon black (Color Index International, PBK-7) is the name of a common black pigment, traditionally produced from charring organic materials such as wood or bone. It appears black because it reflects very little light in the visible part of the spectrum, with an albedo near zero. The actual albedo varies depending on the source material and ...
The black heart emoji can be used to convey those feelings. Because it is the color black, it might also mean that the person sending it to you is feeling a little more serious than usual. They ...

The idea of oil well and oil reserve smoke pluming into the stratosphere serving as a main contributor to the soot of a nuclear winter was a central idea of the early climatology papers on the hypothesis; they were considered more of a possible contributor than smoke from cities, as the smoke from oil has a higher ratio of black soot, thus ...
