Oxygen Assisted Dehydrogenation of Ethane over Alumina Supported Pt-Sn Catalysts
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:376, Doctoral thesis, 2012)The oxygen-assisted dehydrogenation of ethane (ODE) over supported Pt-Sn catalysts seems to be a promising alternative for the conventional steam cracking of ethane for the production of ethylene. However, despite the fact ... -
Oxygen consumption during constant-load exercise - Heterogeneity of quadriceps muscle oxygen consumption during submaximal constant-load dynamic cycling
(Master thesis, 2015)Introduction: There have been a lot of studies examining all aspects of whole body oxygen consumption (pVO2), but when it comes to what happens on a local level, there is still a lot that is unexplored. The aim of this ... -
Oxygen consumption in cycling: The difference between the whole body and the local muscles
(Master thesis, 2011)Introduction: Oxygen consumption during exercise has been extensively studied with the focus primarily on whole body oxygen consumption (tVO2). The purpose of this thesis was to use Near-infrared spectroscopy (NIRS) to ... -
Oxygen Consumption in Cycling: The Relationship between Whole Body Pulmonary O2 Consumption and Muscle Oxygenation in Different Muscles During Constant-Load Cycling
(Master thesis, 2013)Introduction: Oxygen consumption during prolonged cycling exercise has been extensively studied at different work rates and durations, but with the focus primarily on pulmonary oxygen consumption (pVO2). The purpose of ... -
Oxygen evolution on La1-xSrxCoO3 Pellet-Electrodes in alkaline Solution: Charge Carrier density dependence of electrocatalytic activity
(Master thesis, 2012)Alkaline water electrolysis need a catalyst with low overpotential and high current densitiy for oxygen evolution in order to be a commercial viable hydrogen source in the future. Finding and establishing a correlation ... -
Oxygen Incorporation and Release in Metastable Bixbyite V2O3 Nanocrystals
(Journal article, 2016)A new, metastable polymorph of V2O3 with a bixbyite structure was recently stabilized in colloidal nanocrystal form. Here, we report the reversible incorporation of oxygen in this material, which can be controlled by varying ... -
Oxygen Non-Stoichiometry and Electrical Conductivity of La0.2Sr0.8Fe0.8B0.2O3 − δ, B = Fe, Ti, Ta
(Journal article; Peer reviewed, 2014)The oxygen non-stoichiometry was determined by coulometric titration for the perovskite oxides La0.2Sr0.8FeO3 − δ and La0.2Sr0.8Fe0.8B0.2O3 − δ (B = Ti4 + and Ta5 +) in the temperature range 600 °C ⩽ T ⩽ 900 °C and the ... -
Oxygen permeation in symmetric and asymmetric La0.2Sr0.8Fe0.8Ta0.2O3-d membranes
(Journal article; Peer reviewed, 2016)La0.2Sr0.8Fe0.8Ta0.2O3 − δ (LSFT) is a mixed ionic electronic conductor (MIEC) at elevated temperatures and as such a candidate material for applications both in syn-gas synthesis and as electrodes in solid oxide fuel cells ... -
Oxygen stoichiometry and transport properties of cerium niobate
(Journal article; Peer reviewed, 2008)CeNbO4 + δ has been synthesized by both solid state and wet chemical routes and characterized with respect to electrical conductivity and oxygen stoichiometry between 900 °C and 1100 °C and pO2 from 1 bar to 0.002 bar. ... -
Oxygen uptake during functional activities after stroke - Reliability and validity of a portable ergospirometry system
(Journal article; Peer reviewed, 2017)Background People with stroke have a low peak aerobic capacity and experience increased effort during performance of daily activities. The purpose of this study was to examine test-retest reliability of a portable ... -
Oxygen vacancies in the bulk and at neutral domain walls in hexagonal YMnO3
(Journal article; Peer reviewed, 2018)We use density functional calculations to investigate the accommodation and migration of oxygen vacancies in bulk hexagonal YMnO3, and to study interactions between neutral ferroelectric domain walls and oxygen vacancies. ... -

Oxygenate conversion over protonated zeolites.
(Master thesis, 2013)In this thesis, a number of commercial zeolites and a silicalite have been characterised using transmission FT-IR in a vacuum cell. The samples were then investigated in situ by DRIFTS during methanol conversion at 350oC, ... -
Oxytocin and romantic attachments
(Master thesis, 2017)This study assesses how the neuropeptide oxytocin (OT) is distributed in a Norwegian sample and its relationship with adult romantic attachment orientations. Previous research on associations between OT and adult romantic ... -
Oxytocin and vulnerable romantic relationships
(Journal article; Peer reviewed, 2017)Oxytocin (OT) has been implicated in the formation and maintenance of various social relationships, including human romantic relationships. Competing models predict, alternatively, positive or negative associations between ... -
Oxytocin augmentation and its association with labor outcomes
(Doctoral theses at NTNU;2017:163, Doctoral thesis, 2017)Stimulering av rier med oxytocin og sammenheng med fødselsutfall Oxytocin blir ofte brukt under fødselen for å øke styrken på riene. Mangel på klare indikasjoner for bruk av oxytocin har ført til ulik praksis og tilfeldig ... -
