Oxy-combustion coal based power plants: study of operating pressure, oxygen purity and downstream purification parameters
(Journal article; Peer reviewed, 2014)Oxy-combustion coal based power plants are considered one of the cost effective ways to produce CO2 emission free electricity. Recovery of compression heat and the latent heat from the flue gases can further improve the ... -
Oxycodone, Morphine, and Fentanyl in Patients with Chronic Pain: Proposal of Dose-Specific Concentration Ranges
(Peer reviewed; Journal article, 2023)Background: Interpreting opioid concentrations is challenging because of the lack of reference ranges. Therefore, the authors aimed to propose dose-specific concentration ranges in serum for oxycodone, morphine, and ... -
Oxygen absorption in hexagonal manganites
(Doctoral theses at NTNU;2023:192, Doctoral thesis, 2023)Oxygen is one of the worlds most used chemicals, with over 100 million tons of pure O2 being used for industrial and medical purposes each year. The demand for O2 is high, and expected to rise even further due to its ... -

Oxygen and related defects in Czochralski silicon crowns
(Master thesis, 2014)For the purpose of this thesis work, four n-type CZ silicon ingots with different crown tapered angle and shouldering area were characterized in order to understand the oxygen behavior and related defects on ingot top cuts ... -
Oxygen and temperature effect on formation of degradation compounds from MEA
(Journal article; Peer reviewed, 2014)Liquid phase degradation of MEA and the formation of 8 degradation compounds were studied at 4 different oxygen concentrations and three different temperatures. Liquid phase total nitrogen was determined and compared with ... -
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 ... -
