Soot

Soot /ˈsʊt/ is a mass of impure carbon particles resulting from the incomplete combustion of hydrocarbons. It is more properly restricted to the product of the gas-phase combustion process but is commonly extended to include the residual pyrolysed fuel particles such as coal, cenospheres, charred wood, and petroleum coke that may become airborne during pyrolysis and that are more properly identified as cokes or chars.

Soot is theorized to be the second-largest cause of global warming.

Sources

Soot as an airborne contaminant in the environment has many different sources, all of which are results of some form of pyrolysis. They include soot from coal burning, internal-combustion engines, power-plant boilers, hog-fuel boilers, ship boilers, central steam-heat boilers, waste incineration, local field burning, house fires, forest fires, fireplaces, and furnaces. These exterior sources also contribute to the indoor environment sources such as smoking of plant matter, cooking, oil lamps, candles, quartz/halogen bulbs with settled dust, fireplaces, exhaust emissions from vehicles, and defective furnaces. 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. It is generally responsible for the discoloration of the walls above baseboard electric heating units.

Soot (software)

In static program analysis, Soot is a language manipulation and optimization framework consisting of intermediate languages for the Java programming language. It has been developed by the Sable Research Group at McGill University known for its SableVM, a Java virtual machine and the AspectBench Compiler, an open research compiler for AspectJ. In 2010, two research papers on Soot (Vallée-Rai et al. 1999 and Pominville et al. 2000) were selected as IBM CASCON First Decade High Impact Papers among 12 other papers from the 425 entries.

Soot provides four intermediate representations for use through its API for other analysis programs to access and build upon:

The current Soot software release also contains detailed program analyses that can be used out-of-the-box, such as context-sensitive flow-insensitive points-to analysis, call-graph analysis and domination analysis (answering the question "must event a follow event b?"). It also has a decompiler called dava.
