Solvated electrons
WebAmong the radicals (hydroxyl radical (•OH), hydrogen atom (H•), and solvated electron (esol−)) that are generated via water radiolysis, •OH has been shown to be the main transient species responsible for radiation damage to DNA via the indirect effect. Reactions of these radicals with DNA-model systems (bases, nucleosides, nucleotides, polynucleotides of … WebMay 24, 2024 · One perspective of PDSE using a liquid anode is that the role of the plasma to produce a high concentration of solvated electrons at the interface. If this is true, the important parameter is the reduction potential of the solvated electron, which is reported to be −2.77 V. 85 85. R. A. Marcus, J. Chem. Phys. 43, 3477 (1965).

The paper demonstrates this on a wide range of substrates, and shows it working on a gram scale in a larger ball mill (also in one minute!) Needless to say, this is a lot easier ... Webrelated 3dnotion is that of the solvated electron in liq-uids [10, 11, 12]. The formation of 1dpolarons is expected to have an impact on various processes such as electron-hole sepa-ration from bound excitonic states [6, 7], charge transfer reactions, local optical absorption [13] and charge carrier transport. As we discuss the low-frequency ...
