Nanostructure of atmospheric soot particles

open access: yesAtmospheric Environment, 2006
Abstract We studied the structure of atmospheric soot using electron-diffraction-based pair distribution function (PDF) analysis, and compared it with other carbon structures. Two reference materials were used: hydrogen-free amorphous carbon and a kerogen sample with a H/C ratio of 0.61.

Dielectrophoretic Deposition of Graphite Oxide Soot Particles

open access: yesJournal of Nanoscience and Nanotechnology, 2008
Alternating current dielectrophoresis in water was used to position graphite oxide soot (GO-soot) particles generated by rapid thermal expansion of graphite oxide under inert gas. The dielectrophoretic deposition was carried out at a frequency of 10 MHz and a peak-to-peak voltage of 10 V, and the deposited particles were analyzed using scanning ...

Water interaction with hydrophobic and hydrophilic soot particles

open access: yesPhysical Chemistry Chemical Physics, 2008
The interaction of water with laboratory soots possessing a range of properties relevant for atmospheric studies is examined by two complementary methods: gravimetrical measurement of water uptake coupled with chemical composition and porosity analysis and HTDMA (humidified tandem differential mobility analyzer) inference of water uptake accompanied by

A mechanism for the formation of soot particles and soot deposits

Combustion and Flame, 1992
The extent of the role of polycyclic aromatic hydrocarbon (PAH) species in the mechanism of soot formation has not definitely been determined. In previous work using a flat-flame, water-cooled, premixed burner burning ethylene-air flames we investigated the formation and destruction of PAH species up to five aromatic ring structures.

COULOMB INTERACTIONS IN SOOT PARTICLE FORMATION

Journal of Aerosol Science, 2001
Soot formation from uncomplete combustion of hydrocarbons is important problem. However, there are many obscure areas in the mechanism of this process. For example, the role of Coulomb interactions in soot coagulation process is not clarified yet.
