Synthesis and controlled multifunctionalization of mesoscale nanostructured materials

 

We are particularly interested in meso- and nanoporous structures. We synthesize materials using supramolecular interactions to guide the self-assembly of reactive precursors into well-defined structures with high control of particle and pore geometries.

 

     We are especially interested in controlling the assembly of different types of precursors at all size regimes: from individual molecules to nanometer sized structures, to mesoscale assemblies, to macroscopic objects. Bridging the gap between each length scale opens interesting research questions about new physical and chemical behaviors that may emerge from the interactions between the assembled components.

 

      We keep developing new materials with compositions as diverse as silicas, metal oxides, rare earths, carbons and polymers. Significant efforts are devoted to develop methods for controlling the location of multiple functional groups as they are chemically bound to the surface of nanostructured particles.
