Using dark-field microscopy, we observed in situ reactions between individual sodium chloride nanoparticles and sulfur dioxide under ultraviolet irradiation. We found that reaction rates depended on particle size strongly and nonlinearly, with this behavior likely driven by the competition between surface curvature and specific surface area effects. This interpretation was further confirmed through transition state theory calculations and experimental modification of particle surface area.

Accurately measuring ultrafine particle number concentration (PN) from motor vehicle emissions is essential for the prevention and control of atmospheric particulate pollution. The latest Euro 7 emission regulations have lowered the particle size detection threshold from 23 to 10 nm and introduced updated standards for exhaust gas pretreatment and particle counting devices.

We propose a novel method which is accurate in identification of micro-dynamics phase transition processes for ammonium sulfate aerosols by using two-dimensional correlation spectroscopy. we explore more sophisticated structural evolution patterns and the precise sequence of hydrogen-bonding rearrangements. These findings deepen the mechanistic understanding of aerosol phase transitions at the molecular scale, which could inspire new research directions in atmospheric heterogeneous chemistry.

A new aerosol electrometer, the thermal precipitation aerosol electrometer (TPAE), was designed for particles in sizes less than 300 nm, and its prototype performance was experimentally evaluated. The TPAE combines the thermal precipitator in the disk-to-disk configuration with a microcurrent measurement circuit board (i.e., pre-amplifier) for measuring the current carried by collected particles. Our performance study shows that the TPAE performance is consistent with the reference.

The hygroscopic growth of single nanoparticles is important for hygroscopic characteristic analysis of atmospheric particles and for scientific studies involving atmospheric particles. Based on the hygroscopicity difference of subgroups of atmospheric nanoparticles, the classification and proportion analysis of atmospheric nanoparticles has been completed, which has potential significance in predicting the contribution of the atmospheric particulate hygroscopicity and particle growth mechanism.

We demonstrated the usage of the Fourier transform infrared (FTIR) spectroscopic technique to characterize in real time the hygroscopic growth properties of nanoparticles and their phase transition micro-dynamics at the molecular level. We first realize real-time measurements of water content and dry nanoparticle mass to characterize hygroscopic growth factors. We then identify in real time the hydration interactions and the dynamic hygroscopic growth process of the functional groups.

Short summary
A numerical model for a mixing-type condensation particle counter (MCPC) was developed to map the performance for the ultrafine particle detection by varying its operational settings . It is found that a high temperature difference increases the vapor supersaturation and lowers the activation size of particles. Both the total flow rate and the vapor-fraction affect the efficiency of particle condensation growth. This work outlines the future design guidance for small MCPCs.
