The rheological properties of macromolecular and colloidal suspensions are dependent on
the thermodynamic and kinetic parameters that define viscous flow, and remain an active …

In this work we present experimental and simulation analysis of the breakage and
restructuring of colloidal aggregates in dilute conditions under shear. In order to cover a …

We study the first breakage event of colloidal aggregates exposed to shear flow by detailed
numerical analysis of the process. We have formulated a model, which uses Stokesian …

Aggregates grown in mild shear flow are released, one at a time, into homogeneous
isotropic turbulence, where their motion and intermittent breakup is recorded by three …

Breakup of small aggregates in fully developed turbulence is studied by means of direct
numerical simulations in a series of typical bounded and unbounded flow configurations …

Stability characteristics of colloids in a laminar flow have been studied by solving the Fokker–
Plank equation for the pair probability density function. This was done by simultaneously …

Maximum effective hydrodynamic stress,, responsible for the breakup of aggregates with
size comparable to Kolmogorov eddies, was experimentally determined in an aerated stirred …

Aggregates prepared under fully destabilized conditions by the action of Brownian motion
were exposed to an extensional flow generated at the entrance of a sudden contraction. Two …

We have studied the long-term dynamics of shear-induced breakage of individual colloidal
clusters, covering a wide range of fractal dimensions, using Stokesian dynamics. We found …

Particle size affects the toxicity and environmental fate of engineered nanoparticles (NPs).
Although size effects have been widely studied in the experimental NP fate and toxicity …
