The Impacts of Particle Size Distribution and Electrode Structuring on NMC Cathode Performance
… are needed. The commercial active material particles used in battery production are not uniform in shape and size distribution. This heterogeneity results in heterogeneous electrode structures, leading to uneven reactions across the battery electrodes. Moreover, mass transport limitations at …

The effect of particle size distribution on the rheology of ultrafine coal-water slurries
… techniques which require the grinding of coal to sizes below 10 microns. Coal in this size range has inherent material handling problems, most of which can be eliminated by the utilization of this ultrafine coal in a slurry form. Ultrafine coal-water slurries, prepared from an Eastern bituminous …

Use of artificial neural network models to derive particle size distributions and their moments from chord length distributions
… to develop a method for in-lie measurement of a particle size distribution (PSD) of suspended solids and its moments. This was part of a wider study, the aim of which was to develop a system for controlling a crystallisation process. The control strategy to be used is dependent on kinetic models …
