Vladimir Privman's Seminar 21.01.15:
Mechanisms and models of synthesis of uniform colloids, nanoparticles and nanostructures
The reason to focus on the nanoparticles and nanostructures is to understand what is going on in the nano-scale.
They first formed tiny nano crystals and then they grew into colloids.Start with metal ions in salt or chloric acid. The ions reduce into clusters and as they grow they can become aggregated systems or stable nanosystems.
The group is interested in the size distribution. They want to know how do the nanostructures an cristalline particles grow. At this point they cannot see the clusters which are small inough to understand their dynamics.
In order to use a kinetic Monte-Carlo modeling approach a few assumptions are made:

Professor Dennis C Rapaport is currently researching at the Department of Physics in the Bar- Ilan university.
Currently professor Rapaport is focused on a few researches, one of them is the GPU (graphic processor units) based studies of of emergent phenomena.
Emergent phenomena are notable for not being obvious outcomes of the design of the systems in which they appear.
For example: self- assembly, atomistic hydrodynamics and granular segregations.
Rapaport is using Molecular Dynamics Simulation for studying such phenomena.
Moreover, Rapaport is using simulations to study statistical and chemical physics including phase transitions, magnetic systems, percolation and polymers.
