Hydrogen-assisted fatigue crack propagation in a pure BCC iron. Part II: Accelerated regime manifested by quasi-cleavage fracture at relatively high stress intensity range values
(Peer reviewed; Journal article, 2018)Hydrogen effect on fatigue performance at relatively high values of stress intensity factor range, ΔK, of pure BCC iron has been studied with a combination of various electron microscopy techniques. Hydrogen-assisted fatigue ... -
Hydrogen-enhanced fatigue crack growth behaviors in a ferritic Fe-3wt%Si steel studied by fractography and dislocation structure analysis
(Peer reviewed; Journal article, 2019)The effect of hydrogen (H) on the fatigue behavior is of significant importance for metallic structures. In this study, the hydrogen-enhanced fatigue crack growth rate (FCGR) tests on in-situ electrochemically H-charged ... -
Hydrogenation of CO2 to Methanol by Pt Nanoparticles Encapsulated in UiO-67: Deciphering the Role of the Metal−Organic Framework
(Journal article; Peer reviewed, 2019)Metal–organic frameworks (MOFs) show great prospect as catalysts and catalyst support materials. Yet, studies that address their dynamic, kinetic, and mechanistic role in target reactions are scarce. In this study, an ... -
Hydrolicer - Utredning av system, stress og velferd ved avlusing
(SINTEF Ocean rapporter;2018:01081 A, Research report, 2018-12-21)Mekaniske avlusingsmetoder blir stadig vanligere i havbruksnæringa. Det er et stort behov for å dokumentere effekten på fiskevelferden ved bruk av disse metodene, i tillegg til effekten på lusenivået. Ideen bak dette ... -
Hydrological performance of lined permeable pavements in Norway
(Peer reviewed; Journal article, 2021)Lined permeable pavements (LPPs) are types of sustainable urban stormwater systems (SUDs) that are suitable for locations with low infiltration capacity or shallow groundwater levels. This study evaluated the hydrological ... -
