Investigation of slag and condensate from the charge top in a FeSi75 furnace
(Chapter, 2023)Metallurgical silicon/ferrosilicon is produced industrially in submerged arc furnaces by carbothermic reduction of quartz. In addition to raw materials, oxide impurities are present in the furnace. Accumulated slag is ... -
Investigation of Sodium Sulfate Additions into Cryolite-Alumina Melts
(Journal article, 2016)In the Hall-Héroult process, sulfur impurities may not only emit harmful gases but also reduce current efficiency. To better understand this process, the behaviour of sulfur compounds in a cryolite-alumina melt at 1253 K ... -
Investigation of some compounds and gold nanoparticles for photodynamic therapy
(Master thesis, 2018)In this thesis several chemical compounds for possible use as photosensitizers (PS) in photodynamic therapy (PDT) have been investigated. First a photophysical characterization was performed using different spectroscopic ... -
Investigation of Spent Refractory Lining in an Anode Baking Furnace
(Journal article; Peer reviewed, 2017)The refractory lining in anode baking furnaces is exposed to harsh chemical environment and thermal cycling. Spent refractory lining from an anode baking furnace after 4000 days in operation was investigated. Variation in ... -
Investigation of Spin Coating Cerium-Doped Hydroxyapatite Thin Films with Antifungal Properties
(Peer reviewed; Journal article, 2021)In this study, the cerium-doped hydroxyapatite (Ca10−xCex(PO4)6(OH)2 with xCe = 0.1, 10Ce-HAp) coatings obtained by the spin coating method were presented for the first time. The stability of the 10Ce-HAp suspension particles ... -
Investigation of the Chemistry of Liquid H2S Scavengers
(Dr.ingeniøravhandling, 0809-103X; 2002:70, Doctoral thesis, 2002)1,3,5-Tris(2-hydroxyethyl)-1,3,5-triazinane (1), in the industry often referred to as "Triazine", is a widely used liquid H2S scavenger. The goal of the work presented in this dissertation was to examine the chemistry of ... -
Investigation of the diffusion barrier properties in mixtures of mammalian and cold-water fish gelatin
(Master thesis, 2023)Diffusjonsbarriereegenskapene til en gel er en av flere viktige faktorer som bidrar til å definere oppførselen og funksjonaliteten til den. Gelatin er en av mange geleringsmiddel som er vidt brukt i industrien i dag, og ... -
Investigation of the effect of cohabitation on the microbiome and fitness of two Daphnia species.
(Master thesis, 2022)Formålet med denne oppgaven var å undersøke effekten av kohabitering av Daphnia magna og Daphnia pulex på mikrobiomet og levedyktigheten til de respektive artene. Studien benytter labteknikker som ikke er anvendt på D. ... -
Investigation of the Effect of Uncertain Parameters on a Gas-Lifted Oil Network Using a Non-Linear Model Predictive Control (MPC)
(Master thesis, 2022)Dette arbeidet er å finne effekten av å endre viktige parametere i et gassløftet oljeproduksjonsnettverk på produksjonshastigheten og kontrollerens oppførsel. For å kunne teste og undersøke effektene, er en matematisk ... -
