Unexpected Oxidation of Co Nanoparticles Under H2: X‐Ray‐Induced Water Radiolysis in NAP‐XPS Studies

ChemCatChem, Volume 18, Issue 12, 26 June 2026.
Near‐ambient pressure X‐ray photoelectron spectroscopy (NAP‐XPS) was used to study cobalt nanoparticles supported on SiO2/Si under H2 atmospheres. Despite reducing conditions, beam‐induced oxidation was observed and attributed to X‐ray‐driven radiolysis of trace water in the analysis chamber.

The Measurement and Analysis of Pulse Radiolysis Kinetic Oscillograms

Measurement + Control, 1978
The technique of pulse radiolysis used in radiation chemistry is briefly described and some methods for analysing the kinetics of the data obtained are discussed. An X — Y reader, developed for digitising pulse radiolysis oscillograms, is described.

Fast-Neutron Radiolysis of Sub- and Supercritical Water at 300–600 °C and 25 MPa: A Monte Carlo Track Chemistry Simulation Study

Applied Sciences
(1) Background: Supercritical water-cooled reactors (SCWRs) and their smaller modular variants (SMRs) are part of the ‘Generation IV International Forum’ (GIF) on advanced nuclear energy systems. These reactors operate beyond the critical point of water (

Excess Electron Transfer in DNA Studied by Pulse Radiolysis and γ-Radiolysis of Naphthalimide and Iodouridine Modified ODN

, 2016
An excess electron was attached to naphthalimide (NI) modified 12-mer oligodeoxynucleotides (ODNs) and the electron transfer in DNA was investigated by monitoring the transient absorption of NI radical anion (NI•-) during the pulse radiolysis.

Gas production in the radiolysis of poly(vinyl chloride)

, 2008
The yields of H2 and Cl- were determined in the radiolysis of deaerated, aerated, and water mixtures of poly (vinyl chloride) (PVC) powders with γ-rays and 5 MeV He ions. H2 yields with γ-rays are low at about 0.25 molecule/100 eV and they double with He

Radiolysis of an aqueous [11C]iomazenil solution

, 2004
Radiolysis of [11C]iomazenil was investigated in an aqueous solution. Preparation of [11C]iomazenil with [11C]CH3I produced a good radiochemical yield, however, its radiochemical purity was always less than 90% without additives.

Radiolysis and Fe‐Biotite Alteration: Questioning the Origin of H2‐Bearing Fluid Inclusions in the Yorke Peninsula Granites, South Australia

Geochemistry, Geophysics, Geosystems
Multiple drillings in the Yorke Peninsula, South Australia, recently confirmed the presence of natural hydrogen (H2) in shallow sedimentary units. While radiolysis and Fe‐oxidation in the basement are potential generation mechanisms, their respective ...
