The route by which gas-phase molecules in hydrocarbon flames form condensed-phase
carbonaceous nanoparticles (incipient soot) is reviewed. These products of incomplete …

Aromatic hydrocarbons are important components of petroleum-based transportation fuels,
biomass, coal, and solid waste, etc. The reaction kinetics of aromatic hydrocarbons largely …

Extension and clustering of polycyclic aromatic hydrocarbons (PAHs) are key mechanistic
steps for coking and deactivation in catalysis reactions. However, no unambiguous …

On-line mass spectrometry (MS) techniques provide high time resolution for insight into
chemical changes, while eliminating the potential artifacts acquired during sample collection …

We measured aerosol mass spectra and mobility size distributions of particles formed during
the pyrolysis of ethylene, indene, and a mixture of ethylene with a small amount of indene …

Recent investigations illustrated that clustering of hydrocarbons by radical-chain reaction
(CHRCR) mechanism provides key mechanistic steps for the rapid synthesis of polycyclic …

Polycyclic aromatic hydrocarbons (PAHs), serving as critical soot precursors, are formed via
complicated chemical processes, such as the first aromatic ring formation and the aromatic …

Vacuum-ultraviolet (VUV) light is critical for the study of molecules and materials, but the
generation of femtosecond pulses in the VUV region at high repetition rates has proven …

We investigated the pyrolysis of propyne and propene using aerosol mass spectrometry
coupled with tunable synchrotron vacuum ultraviolet photoionization. The results show that …

Polycyclic aromatic hydrocarbons (PAHs) play a major role in the chemistry of combustion,
pyrolysis, and the interstellar medium. Production (or activation) of radical PAHs and …
