Respirable coal mine dust (RCMD) exposure is associated with black lung and silicosis
diseases in underground miners. Although only RCMD mass and silica concentrations are …

Understanding the physicochemical properties of atmospheric particles and the refined
source apportionment become a vital foundation for targeted control of air pollution. The …

Accumulation of float coal dust (FCD) in underground mines is an explosion hazard that
affects all underground coal mine workers. While this hazard is addressed by the application …

To investigate the particle sources before, during, and after the 2022 Beijing Winter Olympic
and Paralympic (WOP) in Beijing, ambient particles were passively collected from January to …

The large amount of coal dust generated by mechanized coal mining poses hazards such as
coal mine explosions, coal worker pneumoconiosis, and atmospheric pollution. Spray dust …

A physical-optics hybrid method designed for the computation of single-scattering properties
of particles with complex shapes, including surface roughness, is presented. The method …

We established an experimental apparatus by combining polarized light scattering and
angle-resolved light scattering measurement technology to rapidly identify the shape of an …

The commercial shadowgraph system, Oxford Lasers VisiSize D30, originally designed to
characterize industrial and agricultural sprays, was tested with respect to the application for …

The microstructure and adhesion force between dust particles determine the dust starting
and migration to a certain extent. By use of scanning electron microscopy, the BET method …

Accurate in-situ measurement of cloud microphysical parameters such as particle diameter,
number concentration and droplet spectrum distribution are of great significance in cloud …
