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.

Singlet oxygen mediated iron-based Fenton-like catalysis under nanoconfinement
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance In the bulk phase, hydroxyl radical from the one-electron transfer and high-valent iron-oxo species from the O-atom transfer compete to be the reactive intermediates in the Fenton and related reactions.

Amplified singlet oxygen generation in metallated-porphyrin doped conjugated polymer nanoparticles [PDF]
, 2018 We report on the mechanism and efficiencies of singlet oxygen O2(1Δg) generation of nanoparticles (NP) of the conjugated polymer (CP) poly(9,9-dioctylfluorene-alt-benzothiadiazole) (F8BT) doped with platinum octaethylporphyrin (PtOEP) suspended in water.

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].

Singlet Oxygen Metabolism: From Genesis to Signaling
Frontiers in Plant Science, 2020 Singlet oxygen (1O2) is an excited state of molecular oxygen with an electron spin shift in the molecular orbitals, which is extremely unstable and highly reactive. In plants, 1O2 is primarily generated as a byproduct of photosynthesis in the photosystem
