WebFurthermore, the hydrodynamic diameter of NPs was positively coincident with the average molecular weight of PEG. As shown in Figure 2 , S1 and S2 with the same core size of 14 nm have a hydrodynamic diameter of 26 nm ( Figure 2A ) and 34 nm ( Figure 2B ), respectively, after modification with PEG 2,000 and PEG 5,000 ( Table 1 ). WebThe flow is in the volume between the inside and outside pipe. Based on equation (1) the hydraulic diameter of a circular duct or tube with an inside duct or tube can be expressed as. dh = 4 (π ro2 - π ri2) / (2 π ro + 2 π ri) = 2 (ro - ri) (3) where. ro = inside radius of the outside tube (m, ft)

WebThe hydrodynamic diameter of the nanoparticles grows from 43 to 54 nm when the Brij 30 concentration is raised from 0.5 to 1 M. The mode caused by Brij 30 micelles is not detected, as we would expect from its intensity of light scattering being very weak. Dynamic light scattering is based on the principle that light scattered by small particles (Rayleigh scattering) fluctuates as the particles undergo Brownian motion. The equivalent spherical diameter for the technique is termed hydrodynamic diameter (HDD). This corresponds to the diameter of a sphere with the same translational diffusion coefficient D as the particle, in the same fluid and under the same conditions. The relationship between the diffusion coefficient D and th…
