Static light scattering of concentrated particle systems in the Rayleigh-Debye-Gans regime: Modeling and data analysis
(Taylor, 2010-09-15)
In this work we give an overview of the Rayleigh-Debye-Gans (RDG) theory applied to the analysis of static light scattering (SLS) data of different types of concentrated particle systems. First some useful models needed ...
Estimation of the Particle Size Distribution of Colloids from Multiangle Dynamic Light Scattering Measurements with Particle Swarm OptimizationEstimación de distribución de tamaños de partículas de coloides a partir de mediciones de luz dinámica a múltiples ángulos con optimización por enjambre de partículas
(Universidad Nacional de Colombia, 2015-04)
In this paper particle Swarm Optimization (PSO) algorithms are applied to estimate the particle size distribution (PSD) of a colloidal system from the average PSD diameters, which are measured by multi-angle dynamic light ...
Molar mass distributions of linear homopolymers by size exclusion chromatography with light scattering detection: A method for automatic band broadening correction
(Elsevier Science, 2019-06)
Size exclusion chromatography (SEC) equipped with a differential refractometer (DR) and a light scattering (LS) detector is a well-known technique for determining the molar mass distribution (MMD) of many polymers. In the ...
Photophysics at Unusually High Dye Concentrations
(American Chemical Society, 2019-01)
The study of the interaction of light with systems at high dye concentrations implies a great challenge because several factors, such as emission reabsorption, dye aggregation, and energy trapping, hinder rationalization ...
A rubber-modified thermoplastic where the morphology produced by phase-separation induced by polymerization disappears at high conversions
(Springer, 2008-03)
An unexpected experimental finding is reported where the primary morphology developed during polymerization-induced phase separation in a rubber-modified thermoplastic practically disappears at high conversions. This process ...
The aqueous Triton X-100 – dodecyltrimethylammonium bromidemicellar mixed system. Experimental results and thermodynamic analysis
(Elsevier Science, 2018-12-20)
The micellization process of the aqueous mixed system triton X-100 (TX100) – dodecyltrimethylammonium bromide (DTAB) has been studied with a battery of techniques: surface tension, static and dynamic light scattering and ...
Device for real-time monitoring of oil-in-water and suspended solids based on thermal lens spectrometry and light scattering
(Optical Society of America, 2020-03)
A novel system suitable for simultaneous monitoring of both oil-in-water and suspended solids based on thermal lens spectroscopy and forward light scattering is presented. The technique measures the concentration of dissolved ...
Derivatized silver nanoparticles as sensor for ultra-trace nitrate determination based on light scattering phenomenon
(Elsevier Science, 2009-01)
New silver nanoparticles coated with EDTA (EDTA-AgNPs) have been synthesized by citrate reduction method and characterized by UV-vis spectroscopy, molecular fluorescence and scanning electron microscopy (SEM). The derivatized ...
Signatures of nonlocality in the first-order coherence of scattered light
(SP MAIK Nauka/Interperiodica, 2007-12)
The spatial coherence of an atomic wavepacket can be detected in scattered photons, even when the center-of-mass motion is in the quantum coherent superposition of two distant, nonoverlapping wavepackets. Spatial coherence ...
Comparison of optical properties of thermally reversible light scattering films consisting in dispersions of polystyrene/naphthalene domains or polystyrene/liquid crystal (EBBA) domains in epoxy matrices
(Springer, 2007-01)
Thermally reversible light scattering (TRLS) films are materials that can be reversibly switched from opaque to transparent states by varying temperature. TRLS films containing different types of dispersed domains in an ...
