A study on the influence of inorganic ions, organic carbon and microstructure on the hygroscopic property of soot [PDF]

open access: yesAtmospheric Chemistry and Physics
Soot is a crucial component of aerosols in the atmosphere. Understanding the hygroscopicity of soot particles is important for studying their role as cloud condensation nuclei (CCN) as well as their chemical behavior and atmospheric lifetime.

Elucidating the polycyclic aromatic hydrocarbons involved in soot inception

open access: yesCommunications Chemistry, 2023
Polycyclic aromatic hydrocarbons are the main precursors to soot particles in combustion systems. A lack of direct experimental evidence has led to controversial theoretical explanations for the transition from gas-phase species to organic soot clusters.

Modeling light scattering from Diesel soot particles [PDF]

open access: yesApplied Optics, 2004
The Mie model is widely used to analyze light scattering from particulate aerosols. The Diesel particle scatterometer, for example, determines the size and optical properties of Diesel exhaust particles that are characterized by the measurement of three angle-dependent elements of the Mueller scattering matrix.

The Illusion of Structural Order: Evaluating the Suppression of Amorphous Carbon Black Pigment Bands in SSE‐Processed Handheld Raman Spectra

open access: yesJournal of Raman Spectroscopy, EarlyView.
The handheld Raman with SSE system efficiently mitigates fluorescence; however, it may also bias the Raman response towards graphitic domains in carbon‐based black pigments, thereby concealing amorphous carbon contributions that are critical for pigment type identification.

Performance improvement of carbon fiber‐reinforced ABS composites by introducing fullerene nanoparticles

open access: yesPolymer International, EarlyView.
Fullerene particles were incorporated with CF‐reinforced acrylonitrile–butadiene–styrene terpolymer (ABS) matrix at three different compositions by a melt‐compounding process. These insights are crucial for the optimization of conductive hybrid composites for various applications.

Disparate evolution mechanisms and optical absorption for transboundary soot particles passing through inland and sea pathways [PDF]

open access: yesAtmospheric Chemistry and Physics
Soot particles, as a type of warming aerosols, play a critical role in climate warming. During transport, these particles undergo atmospheric condition-dependent aging processes that influence their microphysical and optical properties.
