A review of perovskite catalysts for automotive exhaust soot conversion: Structure, activity and design strategies

open access: yesResults in Chemistry
The soot particles in automobile exhaust are one of the main pollutants causing atmospheric pollution and posing health hazards to humans, and their efficient catalytic conversion is crucial for meeting increasingly stringent emission regulations.

Siloxane Decomposition and Clustering in Atmospheric Pressure Non‐Thermal Plasma Discharge

open access: yesPlasma Processes and Polymers, Volume 23, Issue 6, June 2026.
Atmospheric‐pressure He/HMDSO plasmas convert HMDSO to PDMS deposits. At lower power, mass growth is suppressed, while small silicon‐containing fragments and hydrocarbon radicals dominate. Stable small hydrocarbons are formed at higher power, reflecting enhanced fragmentation and recombination pathways.

Experimental Methods for Structural and Morphological Study of Fine and Ultrafine Particulate Produced from Combustion Processes

open access: yes, 2010
Experimental studies have been carried out to understand the chemical structures of the high molecular weight species produced in fuel-rich combustion systems and their role in the soot formation.

China's Contribution to Arctic Black Carbon Declined From 2009 to 2022

open access: yesEarth's Future, Volume 14, Issue 6, June 2026.
Abstract Black carbon (BC) aerosol is an important driver of Arctic warming, and China used to be a major contributor to the Arctic BC burden through long‐range atmospheric transport. Here we show that China's contribution declined significantly from 2009 to 2022, primarily due to reductions in domestic BC emissions following the implementation of ...

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Aerosol and NOx emission factors and submicron particle number size distributions in two road tunnels with different traffic regimes [PDF]

open access: yesAtmospheric Chemistry and Physics, 2006
Measurements of aerosol particle number size distributions (18–700 nm), mass concentrations (PM2.5 and PM10) and NOx were performed in the Plabutsch tunnel, Austria, and in the Kingsway tunnel, United Kingdom.

Particle Emissions from Aviation: Microphysics, Chemistry, and Climate Impact

open access: yes, 2006
The physical and chemical properties of particles emitted from aviation were identified under cruise altitude conditions and with more detailed methods during ground-test studies.

Impact of Shipping Emission Regulations on Atmospheric Vanadium Along U.S. North Atlantic Coast and Over the Western North Atlantic Ocean

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Ship emissions from high sulfur residual fuel oil (RFO) are a major source of air pollution in coastal and marine environments. Emissions include sulfur oxides as well as fine particulate matter (PM2.5) enriched in vanadium (V) and nickel (Ni).

Soot particles filtration - humidity influence

open access: yes, 2019
One of the most frequently use methods to purify air contaminated by particles in many industrial processes is filter media. Although the performance of filter media is relatively well documented under standard conditions (humidity and ambient temperature), few studies are interested in the interaction between moisture and the deposition of particles ...
