Nuclear spin-lattice relaxation in ferrimagnetic clusters and chains: A contrast between zero and one dimensions [PDF]

, 2003
Motivated by ferrimagnetic oligonuclear and chain compounds synthesized by Caneschi et al., both of which consist of alternating manganese(II) ions and nitronyl-nitroxide radicals, we calculate the nuclear spin-lattice relaxation rate 1/T_1 employing a ...

Electroactivity of PIPO nitroxide radical polymer films

Electrochimica Acta, 2021
ABSTRACT Nitroxide radical polymers (NRPs) are widely used as electroactive materials in a range of electrochemical applications, however, their preparation can be complex. Polyamine Immobilised Piperidinyl Oxyl (PIPO) is a commercially available, well-defined, NRP whose electrochemical properties have not been explored to date.
