Renewal of the CEISAM NMR platform ISO 9001 certification
Following an evaluation process conducted by AFNOR, the CEISAM NMR platform ISO 9001 certification (initially obtained in 2022) was renewed for 3 years in November 2025 This certification marks a commitment towards a continuous improvement approach in the service of its users. It is a recognition of the involvement of the platform’s staff in a...
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...
