Hydrated electron in subcritical and supercritical water: a pulse radiolysis study
TL;DR: In this article, temperature dependences of the eaq− spectrum and Gemax were investigated by the pulse radiolysis method over a temperature range of 25-400°C including the supercritical condition and the formation in supercritical water (D2O) was confirmed.

Interaction of hydrated electron with dietary flavonoids and phenolic acids: rate constants and transient spectra studied by pulse radiolysis.
TL;DR: In this article, the reaction rate constants and transient spectra of 11 flavonoids and 4 phenolic acids reacting with eaq−at neutral pH were measured, and it was shown that the o-dihydroxy structure in B ring, the C2,3 double bond, the c3-OH group, and glucosylation, which are key structures that influence the antioxidant activities of the compounds, have little effects on the scavenging activities.

Radiolysis of Bicarbonate and Carbonate Aqueous Solutions: Product Analysis and Simulation of Radiolytic Processes
TL;DR: In this article, a complete set of reaction steps and reliable kinetic data for the radiolysis of (bi)carbonate aqueous solutions at ionic strength close to the groundwater were proposed.

Pulse radiolysis of high temperature and supercritical water: experimental setup and eaq− observation
TL;DR: In this article, the setup of a high-temperature cell for water pulse radiolysis and the preliminary result of e aq-observation were described. But the setup was performed using D 2 O at 25-400°C including supercritical conditions.

Reactions of reducing and oxidizing radicals with caffeic acid:: a pulse radiolysis and theoretical study
TL;DR: In this article, molecular calculations coupled with pulse radiolysis studies are performed to understand the reactions of radicals with caffeic acid, and they find that e aq − and · OH tend to form adducts with N 3, while N 3 tends to abstract H from 4-hydroxyl group in benzene ring, generating a semi-quinoid radical.
