ON TRIMODAL PARTICLE SIZE DISTRIBUTIONS IN FLY ASH FROM

Jun 21, 2006Whereas classical theories regarding coal combustion suggest that mechanisms of ash vaporization and fragmentation lead to bimodal ash particle size distributions (PSDs), this paper presents experimental results supporting other existing hypotheses that three distinct ash modes may be more appropriate.

Microplastic evacuation in fish is particle size‐dependent

Particle concentrations in fish and in the water column exponentially increase with smaller size (Imhof et al., 2016; Roch et al., 2019). In addition, particle size has an influence on the transfer of toxic chemi-cals, as the surface area to volume ratio exponentially increases with smaller size (Lee et al., 2014).

Why results of particle size measurements do not always

Oct 20, 2016The findings of the ILC confirmed that the particle size results of several measurement methods could significantly differ from each other. This is because 'particle size' is usually the size of an equivalent spherical particle that has, in the specific analysis method, the same behaviour as the actual particles, which are not perfectly spherical.
