Heating New Anodes Using the Waste Heat of Anode Butts: Establishing the Interface Thermal Contact Resistance
(Peer reviewed; Journal article, 2021)In order to be able to assess the rate of heat transfer between a new anode and an anode butt, it is critical to measure the interface thermal contact resistance between them. For that purpose, a lab experiment has been ... -
Heavy Metal Emissions from Primary Aluminium Production
(Master thesis, 2022)Tungmetallutslipp i form av luftbårne partikler, eller støv, anses som en miljøbelastning og kan være helseskadelig for både mennesker og dyr. En bedre forståelse av forekomst og sammensetningen er derfor nødvendig for å ... -
Heavy Metal Emissions through Particulate Matter from Aluminium Electrolysis
(Peer reviewed; Journal article, 2023)Heavy metal emissions from the aluminium industry are mainly carried from the plant through fugitive particulate matter (PM) originating from the aluminium electrolysis pot room. To evaluate the behaviour of metal-carrying ... -
Hematite microdisks as an alternative anode material for lithium-ion batteries
(Journal article; Peer reviewed, 2019)In this work, hematite microdisks (500 nm to 1 μm in diameter, ∼200 nm in thickness) have been synthesized by a facile hydrothermal method which exhibited good cycling stability at a current density of 200 mA g−1 and ... -
Heterogeneous nucleation and grain growth of inoculated aluminium alloys: An integrated study by in-situ X-radiography and numerical modelling
(Journal article; Peer reviewed, 2017)A comprehensive study on the heterogeneous nucleation and grain growth of Al-10 wt.%Cu alloys inoculated with Al-5Ti-1B was carried out. To further reveal the solute segregation stifling mechanism, in-situ near-isothermal ... -
Hierarchical structure in Al-Cu alloys to promote strength/ductility synergy
(Peer reviewed; Journal article, 2021)Experimental evidence demonstrated that equal channel angular pressing (ECAP) at cryogenic temperature, in comparison with ECAP at room temperature, led to promoted strength-ductility synergy in an Al-2.5wt.%Cu alloy. The ... -
