This study investigates the long term behavior of glasses used for confinement of nuclear wastes. The results have been obtained from a fruitful collaboration between different CEA laboratories (LLB, LIONS, CEA Marcoule) and the Ecole Polytechnique.
The use of agricultural resources for industrial purposes will undoubtly be one of the major challenges of the 21 st century. Organic biosynthons used in chemistry should progressively replace those coming from fossil fuels.
Following the synthesis by the ribosome, to carry out its biological function, a protein much fold into a single, well defined conformational state: the native state.

See the PhD position opened in 2014 about this subject http://iramis.cea.fr/Pisp/patrick.guenoun/Greenmembranes.html Phase separation of polymer solution, induced by an abrupt quench in temperature, leads to a macroscopic segregation of phases.
The improvement of the mechanical properties of polymer films by inclusion of mineral particles is a well known industrial practice used since the end of the XIX century.
