Improving the Second law efficiency of a cryogenic air separation unit
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:318, Doctoral thesis, 2011)One-quarter of the worldwide greenhouse gas emissions is emitted by fossil fuel based power plants. In order to limit future climate changes caused by these emissions, several types of CO2-capturing power plants are currently ... -
In silico prediction and experimental verification of ionic liquid refractive indices
(Journal article; Peer reviewed, 2018)Ionic liquids (ILs) have seen increasing use as environmentally friendly solvents in a wide array of applications from energy to pharmaceuticals. Among the many properties of interest, the refractive index, is of considerable ... -
In Situ Assessment of a Novel Underwater pCO2 Sensor Based on NDIR Spectrometry Enclosed in a Semipermeable Membrane for use in Aquaculture. Evaluation of Four Biofouling Protection Mechanisms.
(Master thesis, 2019)I lukkede oppdrettsanlegg med resirkulering av vann (RAS) bestemmes vannkvaliteten hovedsakelig av hvor effektivt vannrensesystemet fjerner metabolitter produsert og utskilt av fisken. Hvis rensesystemet ikke fungerer ... -
In situ detection of an unstable C,N-Au(III) chelate by 15N NMR methods
(Peer reviewed; Journal article, 2022)Au(III)-NHC-oxazolyl complexes are prepared by oxidation and anion exchange of the corresponding Au(I)Cl-NHC-oxazolyl precursors, which are synthesized from appropriate imidazolium pre-ligands. As the Au(III) complexes are ... -
In situ X-ray absorption spectroscopic studies of unsupported and supported CoRe during ammonia synthesis/ammonia decomposition
(Doctoral theses at NTNU;2021:407, Doctoral thesis, 2021)In situ X-ray absorption spectroscopy (XAS) studies are crucial for studying the local environment, oxidation state and speciation of transition metals during thermal pre-treatments and during working conditions of catalysts. ... -

Incorporation of Fe@Au nanoparticles into multiresponsive pNIPAM-AAc colloidal gels modulates drug uptake and release
(Journal article; Peer reviewed, 2016)Here, a synthetic method has been optimized for the synthesis of thermoresponsive and pH-responsive poly(N-isopropylacrylamide-co-acrylic acid) nanogels which are subsequently loaded with cytochrome C by using a modified ... -
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 ... -
