dispersity

The table below shows the dispersity of Indian people in the United Kingdom.

The ratio is commonly used as a measure of the dispersity of the molecular weight distribution.

The uniformed polymer chain growth, which leads to low dispersity, stems from the transition metal based catalyst.

Given the limitations of Gini coefficient, other statistical methods are used in combination or as an alternative measure of population dispersity.

This depends on the polymer endgroups, dispersity, or-in the case of copolymers-varying copolymer compositions.

The latter usually have a range of molar masses (unit g mol), the distributions of which are indicated by dispersity (Đ).

In physical and organic chemistry, the dispersity is a measure of the heterogeneity of sizes of molecules or particles in a mixture.

Such is the case also in biological polymers, where the dispersity can be very close or equal to 1, indicating only one length of polymer is present.

Functionalized carbon nanohorns show better dispersity and when bio-conjugated, they can serve biomedical applications such as probing, imaging and drug delivering.

The polydispersity index (PDI) or heterogeneity index, or simply dispersity (Đ), is a measure of the distribution of molecular mass in a given polymer sample.

The density at which systems jam is determined by many factors, including the shape of their components, the deformability of the particles, frictional interparticle forces, and the degree of dispersity of the system.

IUPAC has deprecated the use of the term polydispersity index having replaced it with the term dispersity, represented by the symbol Đ which can refer to either molecular mass or degree of polymerization.

Complete living radical polymerization allows for control of molecular weight and dispersity; however, this is very difficult to achieve and instead a pseudo-living polymerization occurs in which there is only partial control of molecular weight and dispersity.
