The use of the packed column technique for the study of deposition of colloidal particles from dispersions in liquids onto collector beads is described. The technique also allows to investigate the removal of adhered particles, by rinsing the loaded

A finite difference time domain (FDTD) algorithm with nonstandard finite differences is used to compute light scattering by colloidal particles. The objective of this research is to simulate scattering for cases where multiparticle scattering is sign

The packed column technique serves as a useful tool in the investigations of the deposition and removal mechanisms of particles dispersed in a liquid in contact with a solid substrate. A model is presented which can be used to estimate explicitly the

The adhesion phenomena of monodispersed spherical hematite particles on gelatin-coated glass beads were evaluated using the packed column technique and compared with the same system in the absence of the protein. Uptake is observed when the collector

The rate of coagulation in systems of identical and unlike colloids in aqueous media has been studied by a simultaneous multi-angle static light scattering technique. The mixed dispersions consisted of polystyrene latex particles of different radii a

The experimentally determined chromaticities and reflectance spectra of films consisting of uniform ellipsoidal or spherical colloidal hematite particles are compared with calculated values and are found to be in good agreement. The theoretical treat

Experimentally determined stability coefficients for the coagulation of hematite dispersions consisting of uniform spherical particles, and for the deposition of the same solids on glass beads, are compared with theoretically predicted values by the

Coagulation rates in dispersions of uniform spherical particles of surfactant-free sulfate latices, silica and cerium (hydrous) oxide were measured as a function of the ionic strength by a low-angle scattering technique. The results were used to inte

A model is developed to describe multilayer deposition in packed-bed systems. The multilayer deposition is significant for colloid suspensions which are near or beyond the critical coagulation conditions. Packed-bed deposition studies of such suspens

This study describes particle adhesion experiments carried out to elucidate interactions between particles in slurries used for polishing of wafers and disks. For this purpose the packed column technique was employed, which simulated chemical mechani
