Method of Simulation of Magnetic Nanoparticle Aggregation with Using Clustering System

Popis výsledku v původním jazyce

Nanoparticles and colloids in the ground aggregate. In case of simulation of nanoparticle and colloid transport and reactions, dynamics of the aggregation is necessary to be described. Most important causes of the nanoparticle aggregation are heat fluctuation, sedimentation, and drifting of nanoparticles in the medium. In the ground, particles moving in electrolyte may have a nonzero surface charge that affect the rate of particle aggregation. In case of magnetic nanoparticles, attractive magnetic forces have great importance in assessment of the particle aggregation rate. In the paper, it is presented how to simulate the aggregation of nanoparticles in case of magnetic nanoparticles with nonzero surface charge. Influence of magnetic and electrostatic forces is derived, dynamics is describe by the help of mass transport coefficients giving the probability of aggregation, and the mass transport coefficients are modified for nanoparticle size clusters. That helps to compute reactions among all aggregates during aggregation process.
