Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to critically review experimental findings on ionic polymers and colloidal particles and to prove a theoretical framework based on the Poisson-Boltzmann approach. Structure formation in ionic polymer solutions has attracted attention since the days of H. Staudinger and J. D. Bernal. An independent study on ionic colloidal dispersions with microscopy provided a compelling evidence of structure formation. Recent technical developments have made it possible to accumulate relevant information for both ionic polymers and colloidal particles in dilute systems. The outstanding phenomenon experimentally found is microscopic inhomogeneity in the solute distribution in macroscopically homogeneous systems.To account for the observation, the present authors have invoked the existence of the counterion-mediated attraction between similarly charged solute species, in addition to the widely accepted electrostatic repulsion.

This book was released on 2013-11-11 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Colloidal dispersions play a very important role in nature, industry, and daily life. Sometimes, long-term stability is observed or desired as in ferrotluids (composed of very small magnetic particles with radii of ~ 10 nm), which must be stable even in external fields. On the other hand, only short-term stable dispersions may be necessary during actual processing operations, for example, dispersions of magnetite particles during tape manufacture. The stability of dispersions and many of their physical properties are related to the interaction between the particles in the dispersion medium, which may contain surfactants or macromolecular species. If the net interparticle interaction forces are attractive, then aggregation may occur. Two general types of aggregation behavior may be distinguished: coagulation and flocculation. These two terms are frequently used synonymously but IUPAC has recommended the following definitions: Coagulation implies formation of compact aggregates, leading to the macroscopic separation. Flocculation implies the formation of a loose or open network, floc, which may or may not separate macroscopically. Flocculation brought about by the simultaneous coadsorption of polymer molecules on two (or more) particles is referred to as bridging flocculation. If coagulation results in the merging of two particles into one, as may occur with liquid droplets in emulsions, this process is referred to as coalescence.

This book was released on 2014-06-17 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents studies on the interaction of soft materials like surfactants and proteins with hard silica nanomaterials. Due to its interdisciplinary nature it combines concepts from the fields of physical chemistry, nanoscience and materials science, yielding to fundamental insights into the structure-directing forces operating at the nano-scale. It is shown that the morphology of surfactant micellar aggregates adsorbed at the surface of nanoparticles and inside tubular nanopores can be tuned on demand by the co-adsorption of a surface modifier. The interaction of globular proteins with silica nanoparticles is dominated by electrostatic interactions and can be controlled by pH and ionic strength, while the bridging of nanoparticles by adsorbed protein molecules leads to large-scale hybrid aggregates of protein with the nanoparticles. Concepts emerging from the role of electrostatic interactions in the hetero-aggregation of nanoparticles with protein molecules are used for the co-assembly of charged microbeads into linear clusters and chains of controllable length.

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, computer simulations are used to study the properties of new colloidal systems with structured interactions. These are pair interactions that include both attraction and repulsion. Structured colloids differ from conventional colloids in which the interactions between particles are either strictly attractive or strictly repulsive. It is anticipated that these novel interactions will give rise to new microscopic structure and dynamics and therefore new material properties. Three classes of structured interactions are considered: radially structured interactions with an energetic barrier to pair association, Janus surface patterns with two hemispheres of different surface charge, and striped surface patterns. New models are developed to capture the structured interactions of these novel colloid systems. Dynamical computer simulations of these models are performed to quantify the effects of structured interactions on colloid properties. The results show that structured interactions can lead to unexpected particle ordering and novel dynamics. For Janus and striped particles, the particle order can be captured with simpler isotropic coarse-grained models. This relates the static properties of these new colloids to conventional isotropically attractive colloids (e.g. depletion attracting colloids). In contrast, Janus and striped particles are found to have substantially slower dynamics than isotropically attractive colloids. This is explained by the observation of longer-duration reversible bonds between pairs of structured particles. Dynamical mapping methods are explored to relates the dynamics of these structured colloids to isotropically attractive colloids. These methods could also facilitate future nonequilibrium simulation of structured colloids with computationally efficient coarse-grained models.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of the experimental effort is to provide a model particle system that will enable modeling of the macroscopic rheology from the interfacial and environmental structure of the particles and solvent or melt as functions of applied shear and volume fraction of the solid particles. This chapter describes the choice of the model particle system, methods for synthesis and characterization, and results from characterization of colloidal dispersion, particle film formation, and the shear and oscillatory rheology in the system. Surface characterization of the grafted PDMS interface, dispersion characterization of the colloids, and rheological characterization of the dispersions as a function of volume fraction were conducted.

Download or read book Simulation and Network Analysis of Nanoparticles Agglomeration and Structure Formation with Application to Fuel Cell Catalyst Inks written by Razzi Movassaghi Jorshari and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Agglomeration of nanoparticles occurs in a number of colloidal systems related, for example, to material processing and drug delivery. The present work is motivated by the need to improve fundamental understanding of the agglomeration and structure formation processes that occur in catalyst inks used for the fabrication of polymer electrolyte fuel cells (PEMFCs). Particle dynamics simulations are performed to investigate agglomeration under various conditions. The interaction between particles is defined using realistic physical potentials, rather than commonly used potential models, and a novel analysis of the agglomeration and structure formation process is performed using network science concepts. The simulated systems correspond to catalyst inks consisting primarily of carbon nanoparticles in solution. The effect of various conditions such as different force magnitude, shape of the force function, concentration etc. are investigated in terms of network science parameters such as average degree and shortest path. An "agglomeration timescale" and a "restructuring timescale" introduced to interpret the evolution of the agglomeration process suggest that the structure, which has a strong impact on the performance of the eventual catalyst layer, can be controlled by tuning the rate at which particles are added based on the restructuring timescale.

This book was released on 2012-12-06 with total page 848 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, various powerful experimental tools have been developed, such as small angle X-ray and neutron scattering, X-ray and neutron reflection from interfaces, neutron spin-echo spectroscopy and quasi-elastic multiple light scattering and large scale computer simulations. Due to the rapid progress brought about by these techniques, one witnesses a resurgence of interest in the physicochemical properties of colloids, surfactants and macromolecules in solution. Although these disciplines have a long history, they are at present rapidly transforming into a new, interdisciplinary research area generally known as complex liquids or soft condensed matter physics: names that reflect the considerable involvement of the chemical and condensed matter physicists. This book is based on lectures given at a NATO ASI held in the summer of 1991 and discusses these new developments, both in theory and experiment. It constitutes the most up-to-date and comprehensive summary of the entire field.
