Finally, we discuss a process responsible for this difference in particle size distribution between the surface and the subsurface layers. (iac.es)
It is understood that the co-precipitation method produces particles with a wide particle size distribution, as compared with the thermal decomposition method which generates a narrow particle size distribution 15 . (nature.com)
The results are used to determine compliance of the particle size distribution with applicable specification requirements. (astm.org)

This line of research can yield low-cost and real time particle size analysis. (wikipedia.org)
Analysis of live and fixed cells may be based on size, granularity/complexity, fluorescent proteins, cell surface antigen expression, intracellular antigen expression, DNA content. (lu.se)
