Self organization of inorganic nanocrystals in 2D and 3D superlattices: emergence of a new physics
|Date:||Thu Mar 4, 2010|
|Start:||16.00 (Doors open and coffee available at 15.30)|
In this presentation we will show that nanomaterials are old as the world. It will be demonstrated that self-assembly of organic molecules can be used as a universal nanoreactor. Hence, reverse micelles (water in oil droplets stabilized by surfactant molecules) can be used either the make inorganic nanomaterials or to chemically modify enzymes with no change in their activities. Other ways in making inorganic nanomaterials will be presented. These nanocrystals can be self-organized in either hexagonal network (2D) or in supracrystals (3D superlattices).
It will be demonstrated that some chemical properties of inorganic nanocrystals ordered in 2D hexagonal network markedly differ from those expected. It is also demonstrated that crystal growth mechanism markedly differs from what is already established. Nanocrystals self ordered in 3D superlattices are able to breath coherently as atoms in a nanocrystals.Finally it is demonstrated that cracks of nanocrystals film follow a universal scaling law.
