The details of the chemical and physical mechanisms of the soot formation process in
combustion remain uncertain due to the highly complex nature of hydrocarbon flames, and …

Soot particle emission from combustion processes is a significant environmental and health
problem. Optical detection is clearly the only viable choice for in situ PAH and soot …

Combustion-generated soot particles can have significant impact on climate, environment
and human health. Thus, understanding the processes governing the formation of soot …

Combustion is directly related to energy conversion and the environment. Gas-phase
chemical reactions such as thermal decomposition, oxidation and recombination play a …

The processes by which carbonaceous nanoparticles are produced from combustion of
liquid and gaseous fuels are reviewed. The focus of the paper is on the formation and …

This paper presents particle size distributions and chemical compositions of soot measured
using a Scanning Mobility Particle Sizer (SMPS) and a Fourier-Transform Ion Cyclotron …

Fluorescence lifetimes and quantum yields featuring polycyclic aromatic hydrocarbons
(PAHs) and other organics constituting pyrogenic carbon particulate matter (PM) are seldom …

Soot (sometimes referred to as black carbon) is produced when hydrocarbon fuels are
burned. Our hypothesis is that polynuclear aromatic hydrocarbon (PAH) molecules are the …

Brown carbon (BrC) exhibits highly variable light-absorption properties, with the imaginary
part of the refractive indices (k) varying over several orders of magnitude. This poorly …

NASA's Dragonfly mission will send a rotorcraft lander to the surface of Titan to investigate
the prebiotic chemistry, habitability, and potential presence of chemical biosignatures on …
