Size-resolved particle number emissions in Beijing determined from measured particle size distributions [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
The climate and air quality effects of aerosol particles depend on the number and size of the particles. In urban environments, a large fraction of aerosol particles originates from anthropogenic emissions.

Effect of particle size and particle size distribution on the post-liquefaction strength of granular soils

open access: yesSoils and Foundations, 2023
In practice, post-liquefaction strength is largely determined from case histories, but the case history database is limited and there are gaps in the information available in each case.

Characterization of Particle-Size-Based Homogeneity and Mycotoxin Distribution Using Laser Diffraction Particle Size Analysis

open access: yesToxins, 2023
Sample homogeneity dictates whether analyzing a test portion of an entire sample can provide representative information about incurred mycotoxins. In this study, we evaluated particle-size-distribution-based homogeneity of laboratory mycotoxin samples ...
