Comparative performance of catalytic Fenton oxidation with zero-valent iron (Fe(0)) in comparison with ferrous sulphate for the removal of micropollutants [PDF]

open access: yes, 2019
This research aims to depict the comparative performance of micropollutants’ removal by FeSO4- and zero-valent iron (Fe(0))-catalytic Fenton oxidation and to explore the possibilities of minimising the sludge production from the process.

Shear-driven reactions of organosulfur compounds on ferrous surfaces: A molecular dynamics study

open access: yesTribology International, 2022
Abstract Chemical reactions in sliding contacts driven by the combined effects of heat, pressure, and shear underlie the function of lubricant additives that protect surfaces from friction and wear. However, the interplay between thermal and mechanical effects in driving these important reactions, as well as the roles of base oil molecules and ...

Femtosecond X-ray emission study of the spin cross-over dynamics in haem proteins

open access: yes, 2020
In haemoglobin (consisting of four globular myoglobin-like subunits), the change from the low-spin (LS) hexacoordinated haem to the high spin (HS) pentacoordinated domed form upon ligand detachment and the reverse process upon ligand binding, represent ...
