Oxygen uptake profiles during autoxidation of styrene, 4.35 M, in chlorobenzene initiated by 50 mM α,α’-azobisisobutyronitrile (AIBN) in a sample volume 4.0 mL at 30 °C: Curve a, non-inhibited process (the same kinetic trace was also obtained for autoxidation in the presence of nanoparticle 5), Curve b, inhibited by nanoparticles 1A at concentration 10.3 μg/mL, and Curve c, inhibited by compound 3 (dimer of chromanol) at concentration 5 μM.
