LIVERMORE, Calif. -- The longstanding mystery of soot formation, which combustion scientists have been trying to explain for decades, appears to be finally solved, thanks to research led by Sandia ...

Small particles emitted into air during the burning of hydrocarbon fuels damage the human respiratory system and enhance the greenhouse effect. In their agglomerated form, these particles form soot ...

Rethinking the formation and growth of polycyclic aromatic hydrocarbons (PAHs), key contributors to harmful soot particles formed during fuel combustion and the smallest dust grains in interstellar ...

Everyone’s seen soot, but nobody could find the mechanism that generated it. It was a mystery how gaseous hydrocarbon fuel and small soot precursor molecules could form large molecular networks and ...

(Nanowerk News) Soot is one of the world’s worst contributors to climate change. Its impact is similar to global methane emissions and is second only to carbon dioxide in its destructive potential.

The formation of soot during the first phase and the oxidation of soot during the later phase of the combustion in a direct-injection diesel engine have been investigated in detail by an extinction ...

Predicting how soot emissions from aircraft affect the climate through interactions with cirrus clouds is only possible to a limited extent using cloud models. This is partly due to the huge ...

Particle phase photochemical oxidation of polycyclic aromatic hydrocarbons on soot can produce substantial amount of highly unsaturated and oxygenated organic aerosol. That changes soot to better ...

Soot is one of mankind's oldest pollutants. Cavemen blackened their walls with it. During the Industrial Revolution, soot so thoroughly coated the English countryside that white moths died out and ...

Analysis of in-flight emissions from an Airbus A350-900 using 100% sustainable aviation fuel indicates a reduction of 35% in soot particle numbers, and a halving of contrail ice-crystal formation per ...
