3. Functional Nanomaterials II-05.09.2007 Materials research involves two main domains of activity [1]:
Synthesis of novel materials for improving basic knowledge, making correlations between composition, chemical bonding, structure and resulting physical properties
New routes for producing materials by the development of economically cheaper processes
The optimization of the shape of materials (nano crystallites, thin films, single crystals…) for specific applications

7. Functional Nanomaterials II-05.09.2007 ORIGINAL RESULTS The main goal is to prepare original nanostructured compounds: hybrid organic/inorganic powders using hydrothermal method in mild conditions.
The stabilization of hybrid organic/inorganic materials is favored by low temperature and high pressure values.
Pressure can be the autogenous pressure (the vapor pressure of components in solution) or a higher pressure due to the barbotage of an inert gas before heating.
Some examples of hybrid organic/inorganic nanostructured compounds are presented :
Hydroxyapatite/collagen nanocomposites
Hybrid nanostructures based on hydroxyapatite/maleic acid copolymers
Hybrid nanostructures based on hydroxyapatite/layered silicate
Hybrid nanostructures based on ZnO/maleic acid copolymers
