The permeability of porous media as studied by NEMD
(Master thesis, 2021)Det overordnede målet med prosjektet er å bidra til å etablere en beskrivelse av irreversibel termodynamikk for nano-skalaen. Mer spesifikt defineres tilstandsvariabler for fluid som er innesluttet i porøse medier, kunnskapen ... -
The Permselectivity and Water Transference Number of Ion Exchange Membranes in Reverse Electrodialysis
(Journal article; Peer reviewed, 2016)Reverse electrodialysis of saline solutions (RED) is a renewable energy technology with large potential. Key components in the system are the ion exchange membranes. This work evaluates the efficiency of commercially ... -
The persistent spin helix in the presence of hyperfine interactions
(Master thesis, 2018)We study the effect of hyperfine interaction in the persistent spin helix (PSH) by investigating the nuclear spin pumping caused by non-equilibrium electron spin dynamics. In the first two chapters we rederive, based on ... -
The presence and sorption of bisphenols and benzophenones in plastic-containing electronic waste and vehicle fluff from Norwegian waste handling facilities
(Master thesis, 2019)EE-avfall og fluff fra kjøretøy kan bli beskrevet som komplekse blandinger av inhomogene materialer bestående av både verdifulle ressurser og farlige stoffer. Som del av ambisjonen om overgang til en sirkulær økonomi i ... -
The Presence of Per- and Polyfluorinated Alkyl Substances (PFAS) through Different Wastewater and Sludge Treatment Facilities in Norway
(Master thesis, 2021)Abstract will be available on 2024-07-01 -
The presence, emission and partitioning behavior of polychlorinated biphenyls in waste, leachate and aerosols from Norwegian waste-handling facilities
(Journal article; Peer reviewed, 2020)Even though production and open use of polychlorinated biphenyls (PCBs) have been phased out in Western industrialised countries since the 1980s, PCBs were still present in waste collected from different waste handling ... -
The reversible heat effects at lithium iron phosphate- and graphite electrodes
(Journal article; Peer reviewed, 2019)Lithium ion batteries are used to store and produce electric energy. During the charging- and discharging processes, net heat is released or adsorbed in the battery. Temperature is one of the most important factors for ... -
The role of migratory birds in the transport of pollutants to the Arctic
(Master thesis, 2021)Reint intuitivt bør Arktis, en avsidesliggende og øde del av verden, være relativt upåvirka av menneskelig aktivitet. Langtransport og avsetting av persistente, bioakkumulative og giftige stoffer (PBG) fra atmosfæren og ... -
The Salting-out Effect in Some Physical Absorbents for CO2 Capture
(Journal article; Peer reviewed, 2018)The solubility of CO2 in organic solvents N-methyl-2-pyrrolidone (NMP), methanol and monoethylene glycol (MEG) at 30 °C was measured together with its heat of absorption. The salts lithium nitrate (LiNO3), lithium chloride ... -

The use of Green's Functions in Quantum Chemistry
(Bachelor thesis, 2020)Modern quantum chemical calculations commonly use wave function based models or densitry functionaltheory (DFT). Using Green’s functions is an approach that has not been explored much, and is one thathas only been explored ... -
The use of N-terminal peptide fusions to stimulate recombinant gene expression in Escherichia coli
(Master thesis, 2011)Previous studies by the Microbiology and Molecular Genetics (MOLGEN) research group at NTNU have investigated how N-terminal peptide fusions influence gene expression levels. The present study seeks to expand these efforts ... -
Theory and simulation of shock waves: Entropy production and energy conversion
(Journal article; Peer reviewed, 2021)We have considered a shock wave as a surface of discontinuity and computed the entropy production using nonequilibrium thermodynamics for surfaces. The results from this method, which we call the “Gibbs excess method” ... -
The thermal boundary resistance at semiconductor interfaces: a critical appraisal of the Onsager vs. Kapitza formalisms
(Journal article; Peer reviewed, 2018)We critically readdress the definition of thermal boundary resistance at an interface between two semiconductors. By means of atomistic simulations we provide evidence that the widely used Kapitza formalism predicts thermal ... -
Thermal conductivity and internal temperature profiles of Li-ion secondary batteries
(Journal article, 2017)In this paper we report the thermal conductivity for several battery components. Materials were obtained from several electrode- and separator suppliers, and some were extracted from commercial batteries. We measured with ... -
Thermal conductivity and temperature profiles in carbon electrodes for supercapacitors
(Journal article, 2014)The thermal conductivity of supercapacitor film electrodes composed of activated carbon (AC), AC with 15 mass% multi-walled carbon nanotubes (MWCNTs), AC with 15 mass% onion-like carbon (OLC), and only OLC, all mixed with ... -
Thermal conductivity of carbon dioxide from non-equilibrium molecular dynamics: a systematic study of several common force fields
(Journal article; Peer reviewed, 2014)We report a systematic investigation of the thermal conductivity of various three-site models of carbon dioxide (CO2) using nonequilibrium molecular dynamics in the temperature range 300–1000 K and for pressures up to 200 ... -
Thermal Conductivity of Molten Carbonates with Dispersed Solid Oxide from Differential Scanning Calorimetry
