UMR CNRS 6226
Research topics
The CNRS Mixed Research Unit (UMR) 6226, entitled “ Chemical Sciences Rennes consists of twelve research teams and ” incorporates nearly all the researchers and lecturer-researchers in this field on the Rennes campus.
The INSA-Rennes “ Inorganic Materials ” group incorporates lecturer-researchers drawn from two of the twelve teams:
-
Inorganic Materials : Soft Chemistry and Reactivity (Director of research services: Werner PAULUS)
-
Solid State and Materials Chemistry (Director of research services: Maryline GUILLOUX-VIRY). This group concentrates most of its research activity in the field of inorganic materials containing rare earths.
Research projects
-
Synthesis of materials likely to be used as laser amplifiers for optical fibres in telecommunications
Since initial absorption and emission measurements are extremely promising, coordination polymers containing Er3+ ions appear to offer an alternative to the currently favoured doped mineral fibres. This project is a joint-venture with FPSL (Lausanne) and was initiated thanks to funding from Brittany Region (Support agency for regional research projects).
-
Synthesis of nano-materials likely to find applications in the fields of catalysis or medical imagery (contrast agents)
Collaboration with Rhodia Electronics and Catalysis.
-
Synthesis of bifunctional molecular materials
Mixed materials which simultaneously contain lanthanide and transition metal ions are likely to exhibit original photomagnetic properties.
-
Study of reduced oxides of molybdenum and rare-earths
Compounds often showing original magnetic and transport properties.
Technology transfer
In addition to its fundamental research activity, SCR/MI - INSA is heavily involved in industrial research in partnership with local and nationwide industries.
