samples may exhibit a distribution of relaxation times compared to the single relaxation time characteristic of a monodisperse system (ref.
In what follows, it will be called "polydisperse
." PVC 2 where micrometric particles coexist with bigger ones of about 10 pm will be called "bidisperse." PVC 3 composed of a wide population of particles, which diameter around 1-2 [micro]m, will be called "monodisperse."
It consists of polydisperse
spherical particles with a median particle size of [d.sub.50] = 2.3 [micro]m (particle diameter ranges from 0.5 to 3 [micro]m) and an iron content of 97% (density = 7.5g/[cm.sup.3]).
The NIST-traceable polydisperse
glass microspheres are available in the range 0.1 to 2000 micron.
Operating on the principle of separating particles using high resolution packed column hydrodynamic chromatography (HDC), the PL-PSDA measures complex particle size distributions with high precision and accuracy, according to the literature, which is said to make it ideal for narrow distribution, multi-modal or polydisperse
Besides, due to the incomplete understanding of the constraint release effects, the state-of-the-art tube models are not capable to quantitatively predict the linear rheology of arbitrarily polydisperse
systems without free adjustment of model parameters.
complex nanomicelles can be formed in pH range of 5.0-9.0.
Further characterization with SEM and TEM analysis shows the spherical, polydisperse
AgNPs of particle size ranging from 5 to 35 nm with an average size of 28.40 nm.
Since crosslinking israndom, larger molecules in a polydisperse
mixture will acquire proportionately more crosslinks.
These nanoparticles are polydisperse
and aggregated, and their particle sizes were ranging from 6 to 72 nm; such variation in shape and size of nanoparticles synthesized by biological systems is common .
After processing, flax fibers are highly polydisperse
(15) and thus both aspect ratios weighted in number and in surface should be considered.
