Hydrophobic Coatings for Anti-Icing Applications
(Master thesis, 2014)The background for this Master s Thesis is to investigate materials and coatings for use in anti-icing applications. Icing is a problem in many different fields, from aeronautic transport, power lines, and wind turbines ... -
Hydrophobic Coatings for Corrosion Inhibition in Closed Heating Systems
(Bachelor thesis, 2023)Evnen filmdannede aminer har til å beskytte karbonstål, kobber og aluminium fra korrosjon ble undersøkt gjennom å måle kontaktvinkler, hvor målet var å sjekke hydrofobisiteten. De tre filmdannende aminene som ble brukt var ... -
Hydrothermal carbonization of olive wastes to produce renewable, binder-free pellets for use as metallurgical reducing agents
(Journal article, 2020)Torrefaction or hydrothermal carbonization processes were compared for conversion of olive pulp into metallurgical reducing agent. The dependence of yield, CO2 reactivity, and mechanical properties to reaction time and ... -
Hydrothermal syntheis and characterization of BaTiO3 nanoparticles
(Master thesis, 2018)This thesis investigates the size dependent dipole disorder in ferroelectric materials, which leads to a loss of macroscopic ferroelectricity, and the role of the depolarization field on this disorder. Structural ... -
Hydrothermal Synthesis of Alkali Niobates
(Master thesis, 2021)Reaksjonsforholdene under hydrotermal syntese av kalium- og natriumniobater har blitt undersøkt med hensikt å forstå effekten av reaksjonsforholdene på kinetikken, faseformasjonen, morfologien og gitteparametrene. Kalium ... -
Hydrothermal synthesis of hexagonal YMnO3 and YbMnO3 below 250 °C
(Peer reviewed; Journal article, 2021)The hydrothermal synthesis of hexagonal YMnO3 and YbMnO3 are reported using high KOH mineraliser concentrations (>10 M) and low temperatures (<240 °C). The relation between reaction parameters and resulting phase purity ... -
Hydrothermal Synthesis of LaFeO3
(Master thesis, 2011)This work explores the hydrothermal synthesis of LaFeO3 (LFO) nanorods with a high aspect ratio. Synthesis of rod shaped LFO is a stepping stone to the synthesis of strontium doped LFO (LSF) nanorods with high aspect ratio. ... -
Hydrothermal synthesis of SrxBa1–xNb2O6 on nanostructured substrates
(Master thesis, 2019)I nyere tid har syntese av bly-frie ferroelektriske materialer tiltrukket seg stadig mer oppmerksomhet og et av de studerte materialene er strontium barium niobat (SBN). SBN har vist gode elektro-optiske egenskaper, samt ... -
ID22 - the high-resolution powder-diffraction beamline at ESRF
(Journal article; Peer reviewed, 2023)Following Phase 2 of the upgrade of the ESRF in which the storage ring was replaced by a new low-emittance ring along with many other facility upgrades, the status of ID22, the high-resolution powder-diffraction beamline, ... -
Identification of fused pyrimidines as interleukin 17 secretion inhibitors
(Journal article; Peer reviewed, 2018)Inhibiting the interleukin 17 pathway is of interest in a number of autoimmune diseases. Herein, 42 fused pyrimidines have been evaluated as interleukin 17 secretion inhibitors using a phenotypic assay with peripheral ... -
Impact of compensation on solar grade silicon for photovoltaics
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:51, Doctoral thesis, 2012)The steep increase in the market price for silicon feedstock for solar cells experienced at the beginning of the last decade, coupled with a developing industry, opened the possibility for materials produced from different ... -
