Figure 10. Four different ways of controlling the kinetics of polyol reduction and the corresponding morphologies observed for the Pt nanostructures. As the same amount of PVP was present in all four syntheses illustrated here, the striking differences in morphology were not caused by variation in the PVP concentration. It is assumed that the PVP molecules in these syntheses function only as a stabilizer to prevent the resultant nanoparticles from aggregating into larger structures.

Abstract. The subject of this research are the regularities of the particles motion in the electric and thermoelectric fields with distributed potential and the influence of temperature field to the particle motion trajectories in aggregate electric and thermal fields. The analytical solution of the problem of particle motion in thermoelectric field with distributed potential is produced. Common regularities of particle motion and trajectory changes in such fields are derived. It is shown that nonlinear curves give a nonconsiderable part of the trajectory within the macrostructures and so the trajectory shape doesn t considerably influence the electron flow transformation process. Conversely, the trajectory shape does influence the aforesaid processes in micro- and nanostructures defining the specific ways of transformation.
