monodispersity

monodispersity

[¦män·ō·di′spər·səd·ē]
(organic chemistry)
Polymer system that is homogeneous in molecular weight, that is, it does not have a distribution of different molecular-weight chains within the total mass.

Monodispersity, another vital consideration in the development process, remains uncompromised even with larger batches.
Further, the monodispersity of the synthesized nanoparticles was verified using scanning transmission electron microscopy (STEM) analysis.
The ideal result of interface modification is to reduce the filler--filler interaction and to achieve the monodispersity of the nano-size fumed silica in the polymer matrix due to enhanced polymer-filler interactions.
The SLN have high monodispersity, long temporal stability, high loading factors for incorporated molecules and low toxicity (Mehnert and M der 2001).
Besides controlling the phase structure, composition homogeneity, crystallite size, monodispersity, and microstructure, the cost of the product is also an important concern.
Obviously, such nanospheres have superior properties of fluorescence, magnetism, specificity, monodispersity, and agility in colliding and interacting with large species.
These hydrophobized pullulan molecules can form colloidally stable nanoparticles upon self-aggregation in water with monodispersity.
By changing the reaction conditions, such as the molar concentration of the solution, the nature of the solvent, the reaction temperature, and the capping/stabilizing agent, a variety of crystallite sizes and shapes can be synthesized, keeping intact the monodispersity and uniformity of the nanoparticles.
The monodispersity and colloidal stability of the bioconjugates were evaluated by measuring the colloidal particle concentration after selective centrifugation steps and a prolonged storage at 4[degrees]C.
For monodisperse, spherical systems, the law is obeyed over large angular ranges, but where there is departure from monodispersity or sphericity, the limiting slope as q [right arrow] 0 is still valid and related to the [R.
