Science Honey
The laboratory’s students and permanent staff are back on duty to maintain the CEISAM apiary, which has been on the Faculty of Science campus for several years. Visits are organised during the high season with all the beekeeping equipment (smoker, coveralls, etc.) so that members of the laboratory can discover the fascinating world of bees....
Double helicene dye with interesting optical properties
In the framework of a collaboration with the Gryko’s group and several other European teams, the ModES team has published a paper reporting a series of new double helicene with very valuable chiro-optical signatures. In more details, centrosymmetric N,B-doped nanographenes with strong green emission and notable circularly polarized luminescence were obtained. The developed approach involving...

Our research teams
This Institute is organized into five research teams covering coherent areas of activity but which are based on different and highly complementary segments, giving rise to original transversal projects.
On the basis of fundamental and specific expertise, CEISAM is positioned in a certain number of niches of excellence at the interface with the fields of Health, Food chemistry and Materials, through privileged interactions at regional, national and international levels.
Platforms and equipment
To support our research activities, the CEISAM Institute owns many specialist equipments.
These instruments and equipment chains, sometimes intégrated into platforms, aim to synthesize, model, prepare and characterize organic or hybrid items. The European Union, the CNRS and the "Pays de la Loire" region have largely contributed to co-financing these platforms and equipments in particular in NMR, Mass Spectrometry, Molecular Modeling, Optical spectroscopies and microscopy.
