Porosity development in composite carbon materials during heat treatment
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:101, Doctoral thesis, 2007) -
Porosity Reduction and Characterization of Aluminium Components Produced by Additive Manufacturing
(Master thesis, 2017)Selective laser melting (SLM) is a relatively novel method used to produce metallic parts directly from computer models by selectively fusing metallic powder. The production is fundamentally different from traditional ... -
Porous Carbon Anodes for the Supply of Methane during Electrowinning of Aluminium
(Chapter, 2016)One of the major downsides of the current aluminium production process is the high amount of CO2 e mission. One alternative is to replace the consumable carbon anodes with inert anodes so that oxygen evolves instead of CO2 ... -
Porous Silicon as Anode Material for Li-ion Batteries: Structure and Performance
(Master thesis, 2013)Silicon has proven to have a great potential as anode material in lithium-ion batteries due to its high theoretical electrochemical capacity. However, silicon anodes deteriorate quickly during cyclic charging and discharging, ... -
Portland Clinker-Fly Ash Cements – Relation between Compressive Strength and Microstructure
(Chapter, 2021)Portland cements were made by mixing 4 different clinkers with 2 gypsum levels and 0-5% limestone powder. The compressive strength after 28 days of curing varied from 40 (5802) to 70 MPa (9718 psi) for mortar with equal ... -
Position controlled Growth of GaAs/AlGaAs core-shell Nanowires - more uniform in their structural and optical Properties?
(Master thesis, 2014)Semiconducting nanowires (NWs), especially those with a direct band gap, could be promising building blocks in future optoelectronic devices. Position controlled, self catalyzed GaAs/AlGaAs core-shell NWs with an AlGaAs ... -
Possibilities of Improving the Structural Properties of Welded Al-Mg-Si Alloys Through Automated Local Induction Heat Treatments
(Master thesis, 2021)Det er et kjent fenomen at materialet i den varmepåvirkede sonen (HAZ) hos Al-Mg-Si-legeringer blir svekket etter sveising. Østhus et al. har designet et dataprogram som simulerer strekkprøving av sveiste Al-Mg-Si ... -
Post Processing Approach to Model Microsilica Formation
(Peer reviewed; Journal article, 2023)In this work an OpenFOAM-based framework to simulate the evolution of microsilica, which is an important byproduct in the silicon/ferrosilicon industries, is proposed. The framework decouples the combustion reaction of CO ... -
