Soot particles from oil and wood heating systems as well as road traffic can pollute the air in Europe on a much larger scale than previously assumed. The evaluation of the sources during a measuring ...
The telltale signature of a cookstove, commonly used to prepare food or provide heat by burning wood, charcoal, animal dung or crop residue, is the thick, sooty smoke that rises from the flames. Its r...
Remote lakes in a perpetually ice-free area of Antarctica show not only the chemical signature of ancient wildfires, but also some much more recent evidence of fossil-fuel combustion, according to Nat...
For millennia, Greenland's ice sheet reflected sunlight back into space, but satellite measurements in recent years suggest the bright surface is darkening, causing solar heat to be absorbed and surfa...
Knowing the culprits in the discoloration is just the first step in cleaning up the Taj Mahal. Scientists now must determine where the particles are coming from to develop strategies for controlling t...
Atmospheric carbonaceous components, particularly char and soot in ultrafine particles (UFPs; Dp < 0.1 􀈝m) and fine particles (FPs; Dp < 2.5 􀈝m), were measured four times during one...
We use global models to explore the microphysical effects of carbonaceous aerosols on liquid clouds. Although absorption of solar radiation by soot warms the atmosphere, soot may cause climate cooling...
The uptake of NO3 and N2O5 to Saharan dust, ambient aerosols and soot was investigated using a novel and simple relative rate method with simultaneous detection of both NO3 and N2O5. The use of cavity...
Numerous definitions and analytical techniques for elemental (or black) carbon (EC) have been published in the scientific literature, but still no generally accepted interdisciplinary definition exist...
Black soot deposited on Tibetan glaciers has contributed significantly to the retreat of the world's largest non-polar ice masses, according to new research by American and Chinese scientists.Soot abs...
This study assesses in detail the effects of heterogeneous chemistry on the particle surface and gas-phase composition by modeling the reversible co-adsorption of O3, NO2, and H2O on soot coated with ...
In this article, a model which examines the formation and evolution of chemiions in an aircraft engine is proposed. This model which includes chemiionisation, electron thermo-emission, electron attach...
The aging of soot is one of the key uncertainties in the estimation of both the direct and indirect climate effect. While freshly emitted soot is initially hydrophobic and externally mixed, it can be ...
For the treatment of soot by pure HNO3 only reversible uptake with a surface coverage of ~1-2x1014 HNO3 cm-2 was observed for HNO3 mixing ratios in the range 250-800ppbv. Only for higher HNO3 mixing r...
Chemical composition, size, and mixing state of atmospheric particles are critical in determining their effects on the environment. There is growing evidence that soot aerosols play a particularly imp...
