Nanomechanical testing of in situ hydrogen charged high strength steel
(Master thesis, 2013)The effect of finely dispersed titanium carbides on the nanomechanical behavior of high strength steel in the presence of hydrogen has been investigated. Nano sized pillars have been milled from steel samples using a Focused ... -
Nanotechnology for environmentally sustainable electromobility
(Journal article; Peer reviewed, 2016)Electric vehicles (EVs) powered by lithium-ion batteries (LIBs) or proton exchange membrane hydrogen fuel cells (PEMFCs) offer important potential climate change mitigation effects when combined with clean energy sources. ... -
National Guidance for Plastic Pollution Hotspotting and Shaping Action: developing the pilot for Norway
(Master thesis, 2021)Plastic has been widely used in vast volume all over the world for decades, and the plastic waste has caused many environment problems globally, among which the leakage of plastic into the ocean has been particularly ... -
Native range estimates for red-listed vascular plants
(Peer reviewed; Journal article, 2022)Besides being central for understanding both global biodiversity patterns and associated anthropogenic impacts, species range maps are currently only available for a small subset of global biodiversity. Here, we provide a ... -
Natural gas processing using mixtures of glycols and alcohols for removal of water, heavy hydrocarbons and carbon dioxide
(Master thesis, 2014)Developing new gas fields in cold and harsh environment requires cost effective technology for removal of water, heavy hydrocarbons (HHC) and carbon dioxide. Operating at such low temperatures requires a technology that ... -
Natural heat transfer air-conditioning terminal device and its system configuration for ultra-low energy buildings
(Peer reviewed; Journal article, 2020)In consideration of the lowered heating and cooling load of ultra-low energy buildings, a natural heat transfer air-conditioning terminal device (NHTACTD) is presented by the authors. The terminal device is able to undertake ... -
Natural refrigerant heat pumps for residential buildings
(Journal article, 2021)Joining the forces for a clean energy transition, the partners from EU funded TRI-HP project (https://www.youtube.com/watch?v=DYunHAQ1Nd4) have a holistic approach for providing energy to multi-family residential buildings ... -
Natural ventilation in buildings : detailed prediction of energy performance
(Doktoravhandlinger ved NTNU, 1503-8181; 2003:72, Doctoral thesis, 2003)Natural ventilation has during the last decade experienced a renaissance in Europe. The penalty of electrical energy use of traditional mechanical ventilation and air conditioning is the main reason. The present thesis, ... -
Natural Ventilation Modeling in ZEB Lab
(Master thesis, 2020)Bygninger står for 40% av det totale energiforbruket i Europa, og 36% av CO2-utslippene. Høy energieffektivitet i norsk bygningsmasse er derfor en viktig del av det å skape en bærekraftig fremtid og innfri energimål. ... -

Naturleg ventilasjon og komfort i kontorbygg
(Master thesis, 2016)Bygningar står i dag for over 40 % av verdas energiforbruk, noko det er stort ynskje om å redusere. For å få det til, må ikkje berre dagens løysingar bli betre, men også nye alternativ vurderast. Som eit svar på dette vart ... -
Near Ambient Pressure XPS Investigation of CO Oxidation Over Pd3Au(100)
(Journal article; Peer reviewed, 2017)The CO oxidation behavior under excess oxygen and near stoichiometric conditions over the surface of Pd3Au(100) has been studied by combining near-ambient pressure X-ray photoelectron spectroscopy and quadrupole mass ... -
Near Shore FLNG Concept Evaluations
(Master thesis, 2015)This study evaluates different solutions for a LNG facility, partially placed on shore and partially placed on a floater, hereby referred to as at-shore FLNG. There are several advantages with this solution where reduced ... -
Near zero emission energy export and electric power supply based on natural gas
(Master thesis, 2018)In this study, a techno-economic analysis of value chains/cases for near zero emission energy export and power supply to Continental Europe, based on natural gas extracted in Norway and integration of carbon capture and ... -
Near-field response of an axisymmetric jet to transverse acoustic forcing
(Doctoral theses at NTNU;2020:142, Doctoral thesis, 2020)The overall aim of this thesis was to investigate a transversely forced, round air-jet, with focus on the coherent vortex structures formed in the near-field of the jet. Increased knowledge about the interaction between ... -
Near-field response of an axisymmetric jet to transverse acoustic forcing
(Chapter, 2016)Reacting flows in annular enclosures, such as combustion chambers in gas turbine engines, are subject to acoustic waves that inevitably interact with the primary flow [1]. In this study we consider a simplified case of a ... -
Near-Wake of an Inclined 6:1 Spheroid at Reynolds Number 4000
(Journal article; Peer reviewed, 2019)The flow around a 6:1 prolate spheroid at 45 deg inclination angle and Reynolds number 4000 (based on the minor axis) is described. Despite the fact that the inflow is uniform and steady, the resulting wake is highly ... -
Necessary Measures to Include more Distributed Renewable Energy Sources into District Heating System
(Journal article; Peer reviewed, 2017)Low temperature district heating (LTDH) can increase the integration of renewable and waste energy sources that have lots of reliability and acceptance issues. This article aims to identify necessary measures to enable ... -
The necessity to standardise primary energy quality in achieving a meaningful quantification of related indicators
(Journal article; Peer reviewed, 2023)The representativeness of several important parameters, such as energy return on investment (EROI) and those requiring summing primary energy (PE), are often questioned due to the gap in PE quantification technique. This ...
