The graph shows that the [T.sub.g] of PES-OH identified by the maximum of tangent delta (238.5[degrees]C) is higher than the [T.sub.g] of PES-Cl (229.5[degrees]C) at the same molar mass. This can be explained by the influence of the hydroxyl ends groups, which generate strong hydrogen bonds with the sulfone groups, effectively reducing chain mobility, and this effect is absent in PES-CI.
The excess volume of binary mixtures is calculated by where x1, M1 and 1 are the mole fraction, molar mass and density of component (1) respectively .
The molar mass distribution of the unfractionated and fractionated lignin samples showed significant differences between the fractions (Fig.
Although MMD and CCD represent the most significant microstructural information, on occasions, this data alone is not enough due to the interdependence of molar mass and composition.
Similar to the previous experiment, it also appears to be a relationship between the molar mass of the carbamates and their retention by the nanofiltration membrane.
where [M.sub.He+H2O] (kg/mol), [[mu].sub.He+H2O] (Pa x s or kg/(m x s)), and [[rho].sub.He+H2O] (kg/[m.sup.3]) are the molar mass, kinetic viscosity, and density of binary gas consists of [H.sub.2]O, and He, respectively.
Figure 5 shows the molar mass distribution (e.g., [M.sub.n], [M.sub.w], [M.sub.z], and [M.sub.p]) of the PLGA studied for the pellet and for the other times of degradation.
The viscosity-average molar mass ([M.sub.V]) of the chitosan was determined in an Anton-Paar automatic Ubbelohde microviscosimeter.
Enzyme activity leads in alkaline conditions to molar mass decrease of gelatinous hydrolyzate.
The molar mass of standard Berberine and purified Berberine was found as 336.2 in LC chromatogram (Fig S3).
Thus, the researchers measure the mass and the volume of the 28Si sphere as well as the arrangement of the atoms in the crystal and the abundance of the three existing silicon isotopes, which yields the molar mass of the silicon used.
The 13 contributions present molecular field analyses of biaxial phase diagrams, order parameters, the Landau theory of nematic phases, continuum theory, lyotropic biaxial nematics, colloidal systems, and molecular design strategies for low molar mass thermotropic biaxial nematics.
