Summary: The study found that the mass fractions of hydrophilic chemical components in PM2.5 and their mass median aerodynamic diameters were higher under ambient relative humidity (RH) >60% compared to RH <60%. The estimated f(RH) using the revised IMPROVE formula and the Mie model were higher and close to the measured values when RH <60%, but significantly lower than the measured values when RH >60%. A strong linear correlation was observed between the measured f(RH) and the mass ratio of ALWC to PM2.5 when using inline WSIls concentrations, indicating a strong dependence on the mass fraction of ALWC in PM2.5.

Summary: Cascade impactors like the Dekati electrical low pressure impactor (ELPI+) are valuable tools for classifying particles by size range. However, factors like particle loss and particle bounce can cause the measured particle size distribution to differ from the actual distribution. This study investigates these mechanisms and their impact on measurements. The use of greased and ungreased aluminium collection substrates and porous sintered impactor plates were extensively tested in the ELPI+. The aluminium substrates showed a time-dependent decrease in total number concentration and an increase in geometric mean particle diameter, while the sintered impactor plates exhibited negligible time-dependent collection behavior.

Summary: This paper explores the spatio-temporal characteristics of particles from 0.3 to 10 µm in size on the crosswalk and roadside of an urban intersection. The results show that submicron particles have a high correlation with traffic signal and present a bimodal distribution pattern in the green phase. It is also found that submicron particles exhibit a decreasing trend along the crosswalk. Furthermore, the study assesses the pedestrian exposure to different size-fractionated particles and determines the deposition fractions in different age groups. These findings contribute to a better understanding of particle exposure on crosswalks and can assist pedestrians in making informed choices to limit their exposure to pollutants.

Summary: Iron particles in air burn in a heterogeneous combustion mode and the flame speed is greatly affected by particle size. Previous studies on flame propagation in iron dust were based on average particle sizes, but in practical experiments, particle size distributions (PSD) are used, making comparisons challenging. This study aims to understand the effect of particle size distribution on flame propagation by investigating different PSDs and their impact on flame speed and structure. The results show that the width of the particle size distribution plays a crucial role, and experiments and simulations cannot be easily compared if different PSDs are used.

Summary: Coastal new particle formation (NPF) can be complex due to the influence of both continental and marine air masses. This study investigated NPF events and particle size distributions at a coastal industrial park in eastern China from 2018 to 2019. The highest nucleation-mode particle number concentration and NPF frequency were observed in continental-marine air masses originating from the North China Plain and traveling along the coastline. The formation rates of 2 nm particles at this coastal site were similar to those reported in urban environments worldwide, likely influenced by local industrial emissions. Neutral new particle formation pathway dominated over ion-mediated pathway at this coastal site. The behavior of appearance time-based growth rates was similar for both neutral and charged particles.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
