Cryogenic vs. absorption biogas upgrading in liquefied biomethane production – An energy efficiency analysis
(Journal article; Peer reviewed, 2019)Production of liquefied biomethane (LBM) from biogas comprises two major energy intensive processes; upgrading to increase the methane concentration and refrigeration to liquefy the upgraded biogas. Amine-based absorption ... -
Crystal Orientation of Iron Produced by Electrodeoxidation of Hematite Particles
(Journal article, 2013)Electrowinning of iron was conducted in a 50 wt% NaOH-H2O electrolyte with suspended Fe2O3 particles at 110ºC and pure α-Fe films were obtained on a disk cathode with a higher current efficiency than 95%. The Fe2O3 particle ... -
Crystal Phase Mapping by Scanning Precession Electron Diffraction and Machine Learning Decomposition
(Journal article; Peer reviewed, 2018)Analyzing the distribution of crystal phases is required to understand nanostructures. Conventional analysis in the transmission electron microscope (TEM) include acquiring dark-field (DF) images for each expected crystal ... -
Crystal Plasticity Finite Element Simulations using FEpX Open-Source Software
(Master thesis, 2023)Vår forståelse av materialegenskaper er kritisk for vårt moderne liv. Denne forståelsen har historisk blitt laget gjennom fysiske eksperimenter på materialer og deres makrostruktur, men den er vanskelig å oppnå for materialets ... -
Crystal Structure Influences Migration along Li and Mg Surfaces
(Peer reviewed; Journal article, 2020)Dendrite formation on Li metal anodes hinders commercialization of more energy-dense rechargeable batteries. Here, we use the migration energy barrier (MEB) for surface transport as a descriptor for dendrite nucleation and ... -
Crystal structure, thermal expansion and electrical conductivity of LaCoxNiyMozO3
(Journal article; Peer reviewed, 2016)The effect of Mo-substitution was investigated for the LaCoxNiyMozO3 system, obtaining single-phase perovskite for Mo-substitutions up to 20 at%. The crystal structure of the perovskite changed from rhombohedral, orthorhombic ... -
Crystal-plasticity modelling of the yield surfaces and anelasticity in the elastoplastic transition of metals
(Journal article; Peer reviewed, 2024)The paper presents a full-field crystal-plasticity computational investigation of 10 με small-strain-offset yield surfaces with pointed vertexes that are seen in the elastoplastic transition of pre-strained polycrystal ... -
Crystallization and Texturing of SrxBa1–xNb2O6 Thin Films Prepared by Aqueous Solution Deposition─An In Situ X-ray Diffraction Study
(Peer reviewed; Journal article, 2022)Aqueous chemical solution deposition (CSD) is an environmentally friendly and highly flexible fabrication route to prepare oxide thin films. Here, we present an aqueous CSD process for ferroelectric SrxBa1–xNb2O6 (SBN) ... -
Cu Interlayer-Induced High-Strength Laser-Welded AISI 304 Steel-Niobium Joint
(Peer reviewed; Journal article, 2019)Joining niobium to austenitic stainless steel is necessary for the fabrication of particle accelerators. However, the brittle iron-niobium intermetallics formed in the joint significantly reduce the joint strength. Copper ... -
Current Distribution in Bipolar Cell Systems for the Chlor-alkali Industry
(Master thesis, 2018)The chlor-alkali industry is one of Europe s largest chemical industries and produces chlorine gas, hydrogen gas and sodium hydroxide. One of the main production methods is to use membrane cells that are assembled into a ... -
Cyclic Ageing of Aluminium Alloys
(Master thesis, 2022)Cyclic ageing of alloys, specifically heat-treatable aluminium alloys, is being explored as an alternative technique to strengthen them. Recent research has shown that this technique shows benefit in terms of reducing the ... -
Cyclic cold isostatic pressing and improved particle packing of coarse grained oxide ceramics for refractory applications
(Journal article; Peer reviewed, 2018)This study investigated the cold isostatic pressing of coarse grained alumina refractories applying either a cyclic pressure increase or a cycling at maximum pressure. Additionally the effects of the maximum pressure and ... -
Cyclodextrin inhibits zinc corrosion by destabilizing point defect formation in the oxide layer
(Journal article; Peer reviewed, 2018)Corrosion inhibitors are added in low concentrations to corrosive solutions for reducing the corrosion rate of a metallic material. Their mechanism of action is typically the blocking of free metal surface by adsorption, ... -
