As in RAFT processes, as long as the rate of initiation is kept low, the net result is the formation of a monodisperse molecular weight distribution.
22.
Accordingly, ALS enables one to determine hydrodynamic properties of a single monodisperse species as opposed to bulk or average measurements on a sample afforded by conventional light scattering.
23.
"' Monodisperse glass microspheres "'have high sphericity and a very tight particle size distribution, often with CV 95 % of particles in size range.
24.
Similarly, a monodisperse phase has a constant diameter for all particles so that f ( L _ p ) is also a Delta function at every point in space.
25.
Monodisperse beads, also called microbeads, exhibit exact uniformity, and therefore all beads exhibit identical physical characteristics, including the binding capacity and the level of attraction to magnets.
26.
This method allows precise control over shape and size ( monodisperse ), but at the cost of long synthesis times and the inability to observe growth in real-time.
27.
Polydisperse beads, while similar in size to monodisperse beads, show a wide range in size variability ( 1 to 4?m ) that can influence their binding capacity and magnetic capture.
28.
To complicate things further, in talking about nanoparticles it is important that a powder or liquid containing nanoparticles almost never be monodisperse, but contain instead a range of particle sizes.
29.
"' Polypure "'is a Norwegian company that manufactures and markets monodisperse PEG ( polyethylene glycol ) derivatives for applications in nanotechnology, biotechnology and in pharmaceutical sciences.
30.
Monodisperse powders of colloidal silica, for example, may therefore be stabilized sufficiently to ensure a high degree of order in the colloidal crystal or polycrystalline colloidal solid which results from aggregation.
