Formation of calcium naphthenate in water/oil systems, naphthenic acid chemistry and emulsion stability
(Dr. ingeniøravhandling, 0809-103X; 2002:127, Doctoral thesis, 2002)In recent years the production of crude oils with high amounts of naphthenic acids has increased. Certain problems are related to this type of crudes and a better understanding of the chemistry of the naphthenic acids is ... -
Formation of Carbon Build-Up on the Flue Wall of Anode Baking Furnace
(Journal article; Peer reviewed, 2017)A hard carbon build-up layer often forms on the flue wall surface in anode baking furnaces. The layer accumulates over thermal circles and needs to be mechanically removed regularly to ensure sufficient space for the anodes ... -
Formation of Copper–Neodymium Intermetallic Compounds by Carbothermic Reduction of Neodymium Oxide in the Presence of Copper
(Journal article; Peer reviewed, 2018)Carbothermic reduction of neodymium(III) oxide (Nd2O3) was performed by arc melting and in a graphite resistance furnace, using copper as a solvent metal. Successful carbothermic reduction was evident by formation of ... -
Formation of Dislocation Arrays from CSL-type Grain Boundaries in Solar Silicon
(Master thesis, 2019)Fotovoltaisk solenergi er allerede en av de store fornybare energikildene og forventes å være en av de viktigste energiteknologiene i en bærekraftig fremtid. Solceller basert på multikrystallinsk silisium har vært en ... -
Formation of Hard Grey Scale (HGS) on the Surface of a Cold-finger in the Aluminium Production Industry
(Doctoral theses at NTNU;2021:183, Doctoral thesis, 2021)The present work has investigated the formation mechanisms of Hard Grey Scale (HGS) in a duct transporting the off-gas from aluminium production pot cells to the Gas Treatment Centre (GTC). For that purpose, a cooled fouling ... -
Formation of Hydroxyapatite via Transformation of Amorphous Calcium Phosphate in the Presence of Alginate Additives
(Journal article; Peer reviewed, 2019)Hydroxyapatite (HA) is the primary mineral of vertebral tooth and bone tissue; thus, it is often incorporated into synthetic composite materials designed for hard tissue engineering applications. Understanding the formation ... -
Formation of incoherent deformation twin boundaries in a coarse-grained Al-7Mg alloy
(Journal article; Peer reviewed, 2015)Deformation twinning has rarely been observed in coarse grained Al and its alloys except under some extreme conditions such as ultrahigh deformation strain or strain rates. Here, we report that a significant amount of Σ3 ... -
Formation of intermediate bands in silicon by transition metal doping - A DFT/DFTB computational study
(Master thesis, 2016)The intermediate band solar cell offers the possibility of increasing the efficiency of modern-day solar cells. By having a narrow intermediate band placed in the conventional band gap, sequential absorption of photons is ... -
Formation of light (anti)nuclei
(Peer reviewed; Journal article, 2021)The production mechanism of light nuclei, such as deuteron, helium-3, tritium and their antiparticles, has recently attracted an increased attention from the astroparticle and heavy ion communities. The expected low ... -
Formation of Persister Cells and Metabolic Response to Sub-MIC Concentrations of Antibiotics in Escherichia coli
(Master thesis, 2021)Antibiotikaresistente bakterier har blitt et økende problem i behandling av flere ulike sykdommer, men mange antibiotikabehandlinger mislykkes også selv ved fravær av resistente bakterier. Bakterier kan overleve høye ... -
Formation of Primary Silicon and its Influence on the Eutectic Solidification in Unmodified Hypoeutectic Al-Si Alloys - Investigation of Orientation Relationships by EBSD
(Master thesis, 2018)Nucleation and growth of the primary and eutectic silicon in unmodified hypoeutectic Al-Si alloy have been investigated for via optical microscopy, EBSD and SEM . The influence of the cooling rate and phosphorus concentration ... -
Formation of Silicon Carbide and Graphite in the Silicomanganese Process
(Master thesis, 2012)When a liquid SiMn alloy is cooled, carbon is dissolved from the melt. The dissolved carbon either forms graphite or reacts with silicon from the melt to form SiC. The goal of this thesis has been to determine how temperature ... -
Formation of Silicon Carbide in the Silicomanganese Process
(Master thesis, 2011)As the silicon content in a silicomanganese alloy increase, silicon carbide becomes the stable carbon phase. Little work is published on the formation of silicon carbide in the SiMn process. This thesis examines the formation ... -
Formation of {11-21} twin boundaries in titanium by kinking mechanism through accumulative dislocation slip
(Journal article; Peer reviewed, 2016)The twinning behavior and kinking behavior of a commercial purity Ti subjected to room temperature dynamic plastic deformation (DPD) has been studied. Three types of deformation twins, {1012}, {1122} and {1121}, have been ... -
Formation of Σ3{110} incoherent twin boundaries through geometrically necessary boundaries in an Al-8Zn alloy subjected to one pass of equal channel angular pressing
(Journal article, 2018)For coarse grained (CG) alloys with high stacking fault energies (SFEs), like aluminum, deformation twins can rarely form. Here, we report that Σ3{110} incoherent twin boundaries (ITBs) could be generated in a CG Al-8Zn ... -
Formulation and characterisation of drug-loaded antibubbles for image-guided and ultrasound-triggered drug delivery
(Peer reviewed; Journal article, 2022)The aim of this study was to develop high load-capacity antibubbles that can be visualized using diagnostic ultrasound and the encapsulated drug can be released and delivered using clinically translatable ultrasound. The ... -
