Generation of superoxide and singlet oxygen from α-tocopherolquinone and analogues. [PDF]
, 2007 Three potential routes to generation of reactive oxygen species from a tocopherolquinone have been identified. The quinone of the water-soluble vitamin E analogue Trolox C (Trol-Q) is reduced by hydrated electron and isopropanol a hydroxyalkyl radical ...

Erythrocuprein and singlet oxygen
FEBS Letters, 1972 McCord and Fridovich [ 1,2] have shown that erythrocuprein, the copper and zinc containing protein extracted from red blood cells, can enzymatically disproportionate superoxide radicals (Oh), an intermediate of the reduction of oxygen, the generation of which in some Ha 0s -producing biological oxidations has been demonstrated [3].

Study of Singlet Oxygen Dynamics on Silicon Polymer Matrix
Journal of Analytical Methods in Chemistry, 2019 We report a detailed analysis of singlet oxygen generated from the photofunctional polymer film (PFPF) matrix which is the silicone polymer film (PDMS) embedded with a photosensitizer. Activation and deactivation dynamics of singlet oxygen generated from

On self-protecting singlets in cuprate superconductors [PDF]
, 2003 The basal area (Cu-Cu grid) of the cuprate superconductors not only tends to shrink on hole doping, as expected from single electron quantum chemistry, but exhibits also an electronically incompressible "hump'' around optimum doping n_opt = 0.16.
