One-pot Conversion of Biomass to Ethylene Glycol, Propylene Glycol and other Polyols over Carbon Supported Tungsten Catalysts
(Master thesis, 2013)Tungsten carbide and nickel promoted tungsten oxide catalysts supported on CNTs and AC were prepared for the catalytic conversion of cellulose towards polyols, particularly EG. Incipient wetness impregnation was used for ... -
Onsager-symmetry obeyed in athermal mesoscopic systems: Two-phase flow in porous media
(Peer reviewed; Journal article, 2020)We compute the fluid flow time correlation functions of incompressible, immiscible two-phase flow in porous media using a 2D network model. Given a properly chosen representative elementary volume, the flow rate distributions ... -
An Open Access Data Set Highlighting Aggregation of Dyes on Metal Oxides
(Peer reviewed; Journal article, 2020)The adsorption of a dye to a metal oxide surface such as TiO2, NiO and ZnO leads to deprotonation and often undesirable aggregation of dye molecules, which in turn impacts the photophysical properties of the dye. While ... -
OPFRs in e-waste plastic: problems and solutions in the circular economy
(Bachelor thesis, 2023)Etter ulike forbud og restriksjoner på flere bromerte flammehemmere (BFR) på grunn av deres giftige og persistente egenskaper, har bruken av de alternative fosfororganiske flammehemmerne (OPFR) økt betraktelig. OPFRer ble ... -
Optical rotation from coupled cluster and density functional theories
(Doctoral theses at NTNU; 2018:31, Doctoral thesis, 2018)Chiral compounds are of fundamental importance in medical chemistry, biochemistry, and industry. Optical rotation, which is one of the most well-known optical responses of chiral molecules to an electromagnetic field, is ... -
Optically Active Surfactants from the Tartaric Acids. Synthesis and Properties
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:84, Doctoral thesis, 2009) -
Optimalization of a self-healing graphene-polyurethane system
(Master thesis, 2023)En diolfunksjonalisert maleimid 1-(2,3-dihydroksypropyl)-1H-pyrrol-2,5-dion 3 ble fremstilt gjennom en tre-trinns syntese fra maleinsyreanhydrid via en Diels-Alder-beskyttelse, en kondensasjonsreaksjon og en avbeskyttelse ... -

Organisk kjemi som allmenndannelse: En analyse av organisk kjemi i lærebøker i kjemi i perioden 1914-1960
(Master thesis, 2013)I denne oppgaven undersøkes det hvordan organisk kjemi ble presentert i lærebøkene med bakgrunn i innføringen av kjemi som et obligatorisk fag med Lov om høiere almenskole av 1896. Med tanke på dette er lærebøker i perioden ... -
Organophosphate esters in indoor dust from 12 countries: Concentrations, composition profiles, and human exposure
(Journal article; Peer reviewed, 2019)A total of 20 organophosphate triesters (OPEs), including seven alkyl-OPEs, three chlorinated (Cl)-OPEs, seven aryl-OPEs, and three oligomeric-OPEs were measured in 341 house dust samples collected from 12 countries during ... -
Organophosphate esters in sewage sludge from Norway
(Master thesis, 2021)Abstract will be available on 2024-07-01 -
Organosolv pretreatment of biomass for biofuel and biorefinery applications
(Master thesis, 2012)The overall objective of this Master thesis was to establish an optimized ethanol organosolv pretreatment of Norway spruce (Picea abies) for bioethanol production (63 wt% EtOH, pH~3.5 in aqueous phase, 170-240 °C, 90 min) ... -
Origin and spatial distribution of metals in moss samples in Albania: A hotspot of heavy metal contamination in Europe
(Journal article; Peer reviewed, 2018)This study presents the spatial distribution of 37 elements in 48 moss samples collected over the whole territory of Albania and provides information on sources and factors controlling the concentrations of elements in the ... -
Oxidative degradation of triethylene glycol
(Journal article; Peer reviewed, 2024)Triethylene glycol (TEG) is unstable in the presence of oxygen and at high temperatures, though the degradation mechanisms occurring are not properly understood. In attempting to close some of the knowledge gaps, ... -
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 ... -
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, ... -
