1. 1. The turbidity maximum for zinc oxide dispersed in water is determined for three wave-lengths of light. The maximum occurs at .25 micron for wave-length 5500 Å. 2. 2. The turbidity maximum occurs at smaller particle sizes for shorter wave-lengths. The particle size of maximum ...
In the presented work the new method of the analysis of particle distribution in the emulsion according to the sizes with the increased resolution by means of the scattering of light is considered. A significant increase in the possibilities of the proposed method is achieved due to the additional...

Static light scattering only yields accurate results for small particles with narrow particle size distributions. Of the methods to determine particle size distributions, ultracentrifugation and, somewhat less, disc centrifugation and electron ... H Lange - 《Particle & Particle Systems Characterization》 ...
The usual method for determining the size of nanoparticles is dynamic light scattering (DLS) which is alternately called photon correlation spectroscopy (PCS). This method is easy to use in the laboratory, but is subject to artifacts, and sometimes performs poorly for polydisperse samples where ...
Since the particle position is ergodic, the temporal average equals the ensemble average of the autocorrelation image. The lower half image shows the calculation result from the forward operator. f The ground truth particle size distribution (PSD) and the corresponding estimator prediction are plotted...
A method for characterizing the particle size and size distribution of multi-sized polymer lattices was developed by combining quasielastic light scattering (QELS) with a centrifuge. Lattices were first fractionated by centrifugation and the different populations of particles were separated in successive ...
12.18 is invalid since the scattered light intensity strongly depends on the relative refractive index, the wavelength of the laser and the scattering angle, in addition to the particle size. 为Mie散射体(微粒大于大约50-100毫微米), Eq。 12.18是无效的,因为疏散光强度强烈取决于相对折射率、laser的...
Quasi-elastic light scattering, on the other hand, is a powerful investigative tool in the 10–1000 nm size range, but cannot accurately and reproducibly record data of particulate size distribution above 1 micron owing to an increased scattering. While cryo-SEM offers a direct visualization in ...
Within the size fractions, the average particle size is often described by the arithmetic average of the top and bottom sizes in the fraction. The quantity of material in a size fraction is usually measured on a mass basis, but other bases, such as number count, or surface area, may be ...
