A highly reactive chemical intermediate stabilised by weak interactions
Researchers at the CEISAM laboratory (CNRS/University of Nantes) and the Interdisciplinary Centre for Nanosciences in Marseille (CINaM, CNRS/Aix-Marseille University) have succeeded in stabilising a highly reactive reaction intermediate using weak intramolecular interactions. Known as the Meisenheimer complex, this negatively charged and highly reactive intermediate has long been recognised by chemists in aromatic nucleophilic substitution reactions....
Clémence Queffelec awarded the ARKEMA Prize from the Academy of Sciences
Clémence Queffelec, Senior Lecturer at Nantes University, at the Laboratory “Chemistry and Interdisciplinarity: Synthesis, Analysis, Modelling” (CEISAM), has been awarded the ARKEMA Prize by the French Academy of Sciences. The prize (€25,000), created in 2021, rewards decisive scientific advances in the development, characterisation, understanding or implementation of sustainable materials, i.e. materials whose life cycle and...
Pauline CRETIN: Collaboration US2B / AMaCC platform CEISAM
Pauline CRETIN (US2B; Molecular Engineering and Glycobiology Team) has defended her doctoral thesis entitled “Ecophysiology and importance of non-cyanobacterial marine diazotrophs (NCD)” on Friday, October 24, 2025. During her three years of doctoral research, Pauline studied diazotrophy using a model of non-cyanobacterial diazotrophic (NCD) bacteria. Monitoring of nitrogenase activity was carried out at the CEISAM...
