Incorporation of Iron(III) in Silica Aerogels
(Master thesis, 2016)Silica aerogels containing both single site Fe3+ as well as small FexOy nanoparticles of oxide/hydroxide species were synthesized from a waterglass precursor using co-precursor and ambient pressure drying techniques. Fe3+ ... -
Incorporation of Rhenium in ITQ-33
(Master thesis, 2016)ITQ-33 was synthesized by the fluorine route, and the last of three batches was considered phase pure. The as-synthesized samples were then treated with different alkaline and acidic solutions (degermanation), to determine ... -
Influence of Carbon Support on Electronic Structure and Catalytic Activity of Pt Catalysts: Binding to the CO Molecule
(Journal article, 2016)Single-atom catalysts, especially with single Pt atoms, exhibit potentially improved catalytic activity as compared to metal clusters and metal surfaces. Here, the atop and bridged bondings of the CO molecule on the Pt/C ... -
Influence of electrode gas flow rate and electrolyte composition on thermoelectric power in molten carbonate thermocell
(Journal article, 2016)A thermocell (thermo-electrochemical cell) is an electrochemical system with two identical electrodes placed at different temperatures in an electrolyte solution. Ion transport between the electrodes due to the temperature ... -
Influence of Electrode Gas Flow Rate and Solid Oxide Ratio in Electrolyte on the Seebeck Coefficient of Molten Carbonate Thermocell
(Journal article; Peer reviewed, 2017)Thermocells represent a promising way to utilize heat as a power source. The aim of this work is to develop a thermocell with identical gas electrodes using molten carbonate-based electrolytes. The cell can generate power ... -
Influence of grain size, organic carbon and organic matter residue content on the sorption of per- and polyfluoroalkyl substances in aqueous film forming foam contaminated soils - Implications for remediation using soil washing
(Peer reviewed; Journal article, 2023)A soil that was historically contaminated with Aqueous Film Forming Foam (AFFF) was dry sieved into size fractions representative of those produced during soil washing. Batch sorption tests were then conducted to investigate ... -
The influence of interfacial transfer and film coupling in the modeling of distillation columns to separate nitrogen and oxygen mixtures
(Peer reviewed; Journal article, 2020)Coupling between heat and mass transfer occurs across interfaces and in vapor and liquid films. In this work, we present the first rigorous investigation of the role of these physical phenomena in the mathematical modeling ... -
Influence of Mg and Ce in Ni/USY zeolites on CO2 methanation
(Bachelor thesis, 2020) -
Influence of rate of salinity increase on nitrifying biofilms
(Journal article; Peer reviewed, 2019)A strategy for rapid increase in salinity with minimal impact on nitrification is important for ammonia removal from saline effluents, especially in recirculating aquaculture systems with high water reuse. To study the ... -
Influence of siderophore-iron complexation on the growth of the diatom Skeletonema costatum: a mass spectroscopy approach
(Master thesis, 2016)The growth of the diatom Skeletonema costatum was monitored using in vivo fluorescence under concentration gradients of desferrioxamine B (DFB) and enterobactin to test the siderophores effect on iron bioavailability. ... -
The influence of temperature on cellulose swelling at constant water density.
(Peer reviewed; Journal article, 2022)We have in this paper investigated how water sorbs to cellulose. We found that both cellulose nanofibril (CNF) and cellulose nanocrystal (CNC) films swell similarly, as they are both mainly composed of cellulose. CNF/CNC ... -
Infrared spectroscopic studies of zeotype and zeolite catalyzed hydrocarbon/oxygenate conversion reactions
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:121, Doctoral thesis, 2014)The methanol to hydrocarbons (MTH) reaction is an important reaction involved in the chain of processes for the conversion of alternative carbon sources into liquid fuel and olefins. One key reaction in the complex MTH ... -
