We have used high-resolution solid-State 13C NMR to better understand and optimize the conservation process of archaeological waterlogged woods by polyethylene glycol (PEG) impregnation via the  study of the molecular interactions between PEG and residual celluloses.
In a molecule bearing several unpaired local spins, one of the pertinent parameters that govern its magnetic properties is the magnetic exchange interaction constant J that describes the way spins “talk to each other” through the atoms connecting them (bridges).
Dans le cadre du retraitement des déchets nucléaires, le processus d'extraction en phase liquide-liquide est couramment utilisé.
