D[4, 3], volume moment mean; Dv10, Dv50, and Dv90, the measured diameters below which 10%, 50%, and 90% of the particle population lies, on the basis of volume.
Values are mean±SD (n=5).
***p<0.001.
Defines the width of the particle size distribution and is equal to (Dv90 - Dv10) / Dv50.
a-dMeans with different letters within the same row are significantly different by Duncan’s multiple range test (p<0.05).
