TL;DR: In this article, the optimal experimental design methodology (OED) was used to investigate the effects of primary reaction parameters (Fe(II)- and H 2 O 2 -concentrations and temperature) and to find the best parameter ranges for process optimization.

TL;DR: Evidence is brought of two different reaction pathways: introduction of OH- and C=O-groups at the polystyrene pathways is mainly due to the reaction of reactive oxygen species produced in the gas phase between the VUV-radiation source and the substrate and oxidative fragmentation leading to morphological changes is initiated by electronic excitation of the polymer.

TL;DR: It is confirmed that enhanced hydrogen peroxide production takes place upon VUV irradiation of aqueous solutions of organic compounds and that recombination of hydroxyl radicals is kinetically disfavoured.

TL;DR: In this paper, the authors investigated the quenching of singlet oxygen (O21Δg) by humic substances (HSs) of different origins by measurements of the Singlet oxygen luminescence at 1270 nm.

TL;DR: In this article, the near-infrared luminescence of singlet oxygen (1O2) has been measured in order to determine the efficiency of 1O2 quenching by two carotenoid compounds, β-carotene and canthaxanthin.
