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 ... -
Crystalline GaSb-core optical fibers with room-temperature photoluminescence
(Journal article; Peer reviewed, 2018)Glass-clad, GaSb-core fibers were drawn and subsequently laser annealed. The asdrawn fibers were found to be polycrystalline, possess Sb inclusions, and have oxide contamination concentrations of less than 3 at%. Melting ... -
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) ... -
Crystallization behavior of an X-Ray Contrast Agent Intermediate at high Supersaturations and Temperatures
(Master thesis, 2016)This project comprises studies of crystallization of an aromatic amine, which is an intermediate in the production of the X-ray contrast agent Iohexol at GE Healthcare Lindesnes Site. Crystallizations from highly supersaturated ... -
Crystallization kinetics and growth of struvite crystals by seawater versus magnesium chloride as magnesium source: Towards enhancing sustainability and economics of struvite crystallization
(Peer reviewed; Journal article, 2020)The recycling of nutrients from wastewater and their recovery in the form of valuable products is an effective strategy to accelerate the circular economy concept. Phosphorus recovery from wastewater by struvite crystallization ... -
Crystallographic relationships of T-/S-phase aggregates in an Al–Cu–Mg–Ag alloy
(Journal article; Peer reviewed, 2018)T-(Al20Cu2Mn3) phase dispersoids are important for limiting recovery and controlling grain growth in Al-Cu alloys. However, these dispersoids can also reduce precipitation hardening by acting as heterogeneous nucleation ... -
csdR, an R package for differential co-expression analysis
(Peer reviewed; Journal article, 2022)Background Differential co-expression network analysis has become an important tool to gain understanding of biological phenotypes and diseases. The CSD algorithm is a method to generate differential co-expression networks ... -
CTmax is repeatable and doesn't reduce growth in zebrafish
(Journal article; Peer reviewed, 2018)Critical thermal maximum (CTmax) is a commonly and increasingly used measure of an animal’s upper thermal tolerance limit. However, it is unknown how consistent CTmax is within an individual, and how physiologically taxing ... -
Cu atoms suppress misfit dislocations at the β″/Al interface in Al-Mg-Si alloys
(Journal article, 2016)The Cu interactions with the Al–Mg–Si alloy main hardening phase β″ are investigated in atomic scale, by using experimental and simulated high angle annular dark-field scanning transmission electron microscopy techniques ... -
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 ... -
Cu-Promoted Fe-Based Catalyst for Biomass-Derived Synthesis Gas for the Fischer-Tropsch Synthesis
