Particle Size Distribution Effect on Cassava Starch and Cassava Bagasse Biocomposites
(American Chemical Society, 2019-01)
Regarding the growing interest in the development of biodegradable films from renewable sources, this work is focused on the utilization of cassava roots bagasse as a natural filler of cassava starch films. Homogenous films ...
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 ...
Non-uniform size of catalyst particles. Impact on the effectiveness factor and the determination of kinetic parameters
(Elsevier Science SA, 2020-09)
The analysis of the effectiveness factor in catalytic particles with non-uniform size, was performed. The procedure proposed by Weisz and Prater to determine the intrinsic kinetic constants from experimental results was ...
Determination of Size Distributions of Concentrated Polymer Particles Embedded in a Solid Polymer Matrix
(Wiley VCH Verlag, 2008-04)
In this work we present the results obtained from the size characterization of polymer particles embedded in a solid polymer matrix using Static Light Scattering (SLS) and Scanning Electron Microscopy (SEM). The analyzed ...
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 ...
Capillary hydrodynamic fractionation of hydrophobic colloids: Errors in the estimated particle size distribution
(Elsevier Science Inc, 2014-05)
Capillary hydrodynamic fractionation (CHDF) with turbidity detection at a single wavelength is an ana-lytical technique that is often used for sizing the sub-micrometric particles of hydrophobic colloids. Thisarticle ...
Modeling a Fluidized-Bed Reactor for the Catalytic Polymerization ff Ethylene: Particle Size Distribution Effects
(Planta Piloto de Ingeniería Química, 2005-12)
Particle size distributions in the output stream of commercial, fluidized-bed reactors for ethylene polymerization are analyzed using a mathematical model. The impact on the overall reactor performance of the universe of ...
Particle size effects on magnetic properties of yttrium iron garnets prepared by a sol-gel method
(Elsevier Science, 2002-05)
We present detailed measurements of field - and temperature - dependence of magnetization in nanocrystalline YIG (Y3Fe5O12) particles. The fine powders were prepared using sol-gel method. Samples with particle sizes ranging ...
The role of natural mineral particles collected at one site in Patagonia as immersion freezing ice nuclei
(Elsevier Science Inc, 2018-05-15)
This work studies the role of mineral particles collected in the region of Patagonia (Neuquén, Argentina) as ice nuclei particles (INPs) by immersion freezing mode. The particle immersion-freezing ability was analyzed under ...
