General integral relations expressing the droplet radius and time of the droplet nonstationary growth as nonlinear functions of solution concentration in the droplet have been derived. These relations are valid for a supercritical droplet (i.e., sufficiently large droplet, for which the Laplace...

It is shown that the mole fractions of components within a droplet growing in an atmosphere of two condensing gases and a carrier gas approach their stationary values with a power-law behavior in time on a large scale and with exponential behavior on a small scale for both diffusion-controlled...

The encounter effect on the dynamics of fluctuations in phase separations of off-critically quenched binary systems is studied by performing three-dimensional computer simulations of the droplet growth model proposed recently by the authors. The dynamical behavior of the scattering structure...

A systematic framework introduced recently to obtain parameter-free predictions of material properties of dilute polymer solutions in extensional flows is reviewed. The essential constraint of ensuring that the model polymer molecule has a finite length is met by using a bead–spring chain...

We use Brownian dynamics simulations to study the adsorption behavior of a nanosized particle in polymer brushes. The adsorption process, the dynamic behavior of the nanoparticle in the brush, the penetration depth, the diffusion coefficient of the nanoparticle in different depths of the brush,...

Brownian dynamics simulations of interacting magnetic particles in a quasi-two-dimensional ferrofluid system are performed at zero temperature, under the influence of oscillatory shear flow in the absence of external magnetic fields. Starting from chain-like clusters of the particles, we study...

We examine the condensed states for a semiflexible polymer in poor solvent as a function of stiffness, focusing on the transition region between globule and torus. Conservative estimates for the upper and lower bounds to the globule–torus transition region are found. These are then used to...

The dynamics of a charged two-dimensional colloidal system in the presence of a one-dimensionally modulated laser field is studied by using Brownian dynamics simulations. The present model consists of interacting point particles in two dimensions, including effects of screened Coulomb force,...

Aggregation in a colloidal system composed of positive and negative particles is studied by simulations and theoretically. The system is comprised of a 50/50 mixture of particles with the same size and opposite charge. Brownian dynamics simulations are performed, varying the range of interaction...

Electrophoretic properties of charged colloidal suspensions are investigated using a hybrid simulation method. In this method, the colloidal particles are propagated via Newton’s equations of motion using molecular dynamics (MD), while they are coupled to a structureless solvent that is...
