On the theory of the ceramic densification process an of recrystallization in colloidal solutions [PDF]

, 1972
In a short survey the analogy between the theories on diffusion in solids and in solutions is shown. As a result, analogous theories are developed for the ceramic sintering process and the recrystallization in colloidal solutions.

Nanoemulsion stability: experimental evaluation of the flocculation rate from turbidity measurements

, 2012
The coalescence of liquid drops induces a higher level of complexity compared to the classical studies about the aggregation of solid spheres. Yet, it is commonly believed that most findings on solid dispersions are directly applicable to liquid mixtures.

Influence of cell surface and nanomechanical properties on the flocculation ability of industrial Saccharomyces cerevisiae strains [PDF]

, 2017
In the past few years, atomic force microscopy (AFM) has provided novel information on the ultrastructural and nanomechanical properties of yeast cell walls that play a major role in determining the flocculation characteristics of the yeasts.

Describing Mining Tailing Flocculation in Seawater by Population Balance Models: Effect of Mixing Intensity

Metals, 2020
A population balance model (PBM) is used to describe flocculation of particle tailings in seawater at pH 8 for a range of mixing intensities. The size of the aggregates is represented by the mean chord length, determined by the focused beam reflectance ...

Applying a logistic growth equation to model flocculation of sediment in the presence of living and dead organic matter

Frontiers in Marine Science, 2023
In the present study, we aim to parameterize a flocculation model, based on a logistic growth equation, by conducting laboratory experiments. The flocculation experiments are performed using two types of natural sediments and different flocculating ...

Medium dependence of asphaltene agglomeration inhibitor efficiency

, 2007
Applying chemical additives (molecule inhibitors or dispersants) is one of the common ways to control asphaltene agglomeration and precipitation. However, it is not clear why at some conditions the synthetic flocculation inhibitors as well as resins not ...

Emulsion formation and stabilization by biomolecules: the leading role of cellulose [PDF]

, 2019
Emulsion stabilization by native cellulose has been mainly hampered because of its insolubility in water. Chemical modification is normally needed to obtain water-soluble cellulose derivatives.
