Hole annihilation vs. induced convection: Breakdown of different contributions to the photocorrosion mechanism of oxide-covered iron
(Peer reviewed; Journal article, 2021)The mechanism behind corrosion rate increase of anodised iron under illumination has been studied by comparing photocurrents with corrosion currents from polarisation curves under controlled convection. Under illumination ... -
Hole cleaning and wet-granular rheology of rock cutting beds: Impact of drilling fluid composition
(Peer reviewed; Journal article, 2022)Cuttings-beds formation is an issue that must be considered during all wellbore drilling operations. This problem increases at highly deviated or horizontal wells, where cuttings removal efficiency becomes one of the most ... -
Holistic approach for studying planetary hydrospheres: Gibbs representation of ices thermodynamics, elasticity and the water phase diagram to 2300 MPa
(Peer reviewed; Journal article, 2020)Gibbs energy representations for ices II, III, V, and VI are reported. These were constructed using new measurements of volumes at high pressure over a range of low temperatures combined with calculated vibrational energies ... -
