D10, particle size of the minimum 10% measurement; D50, particle size of the minimum 50% measurement; D90, particle size of the minimum 90% measurement.
All values are mean±SD (n=3).
Means with different superscript within a same row are significantly different by Duncan’s multiple test (p<0.05).
p<0.01, ***p<0.001 by t-test.
