Low-Temperature Oxidation of Methane (CH4) and Carbon Monoxide (CO) over Pd/Al2O3 and Pd-Ag/Al2O3 Catalysts
(Master thesis, 2021)Oksidasjon av metan- og karbonmonoksid ved lave temperaturer blir sett på som lovende løsninger for å kunne møte fremtidens krav om utslippsredusering. Katalytiske systemer gjør det mulig, for eksempel, å omdanne forurensninger ... -
Low-Temperature Plasma-Enhanced Atomic Layer Deposition of SiO2 Using Carbon Dioxide
(Peer reviewed; Journal article, 2019)In this work, we report the successful growth of high-quality SiO2 films by low-temperature plasma-enhanced atomic layer deposition using an oxidant which is compatible with moisture/oxygen sensitive materials. The SiO2 ... -
Lower survival probability of house sparrows severely infected by the gapeworm parasite
(Journal article; Peer reviewed, 2014)The effect of parasites in natural populations has received increasing attention in recent years. Studies have shown that parasites may play an important part in population ecology due to their potential effects on host ... -
Lower trophic level mixed fishery (LOTROMIX) - Implications for ecosystem and management
(Master thesis, 2017)There is an increasing interest in new marine resources for the production of aquaculture feed, to meet the increasing growth of the aquaculture industry. Marine species from lower trophic levels are a potential resource ... -
Lugworms (Arenicolidae, Annelida) in Norwegian waters - species diversity and habitat preferences
(Master thesis, 2022)Arenicola marina Linnaeus, 1758 er en godt kjent art langs norskekysten. Nylig ble en ny art beskrevet som tidligere ble identifisert som A. marina. Denne nye arten, Arenicola defodiens Cadman & Nelson-Smith, 1993 har ikke ... -
Luminescent Eu3+-doped NaLa(WO4)(MoO4) and Ba2CaMoO6 prepared by the modified Pechini method
(Journal article; Peer reviewed, 2016)Modified Pechini synthesis routes were developed for synthesis of the novel red phosphor materials NaLa(WO4)(MoO4):Eu3+ and Ba2CaMoO6:Eu3+. Phase pure NaLa(WO4)(MoO4):Eu3+ was obtained at calcination temperatures ≥600 °C ... -
Luminescent silica-based nanocomposites for detection of liquid organic compounds
(Doctoral theses at NTNU;2021:307, Doctoral thesis, 2021)The main aim of this thesis is to prove a concept of a novel detection method for liquid organic compounds (LOCs) based on luminescent nanoparticles (NPs) that can be used in oil-field applications. Before starting an ... -
Lyotropic Liquid Crystals: CO2 Capture and Phase Behavior
(Doctoral theses at NTNU;2019:122, Doctoral thesis, 2019)The rising greenhouse gas emissions, in particular CO2, have contributed to an increase of the global temperature. In order to combat the severe effects of climate change, actions are being taken to favor a switch to low ... -
LysoPC and PAF Trigger Arachidonic Acid Release by Divergent Signaling Mechanisms in Monocytes
