Thermo-molecular orientation effects in fluids of dipolar dumbbells
(Journal article, 2014)We use molecular dynamics simulations in applied thermal gradients to study thermomolecular orientation (TMO) of size-asymmetric dipolar dumbbells with different molecular dipole moments. We find that the direction of the ... -
Thermo-osmosis in membrane systems: a review
(Journal article; Peer reviewed, 2017)We give a first review of experimental results for a phenomenon little explored in the literature, namely thermal osmosis or thermo-osmosis. Such systems are now getting increased attention because of their ability to use ... -
Thermo-osmotic pressure and resistance to mass transport in a vapor-gap membrane
(Peer reviewed; Journal article, 2021)We have investigated the transport of fluid through a vapor-gap membrane. The transport due to a membrane temperature difference was investigated under isobaric as well as non-isobaric conditions. Such a concept is relevant ... -
Thermodynamic Characterization Of Two Layers Of CO2 On A Graphite Surface
(Journal article; Peer reviewed, 2014)We find by examination of density profiles that carbon dioxide adsorbs on graphite in two distinct layers. We report the activity coefficient, entropy and enthalpy for CO2 in each layer using a convenient computational ... -
Thermodynamic Properties of Hydrogen Dissociation Reaction from the Small System Method and Reactive Force Field ReaxFF
(Journal article, 2017)We present thermodynamic properties of the H2 dissociation reaction by means of the Small System Method (SSM) using Reactive Force Field (ReaxFF) simulations. Thermodynamic correction factors, partial molar enthalpies and ... -
Thermodynamic properties of the 3D Lennard-Jones/spline model
(Peer reviewed; Journal article, 2019)In the Lennard-Jones spline (LJ/s) model, the Lennard-Jones (LJ) potential is truncated and splined so that both the pair potential and the force continuously approach zero at rc ≈ 1.74σ. It exhibits the same structural ... -
Thermodynamically consistent modeling of gas flow and adsorption in porous media
(Journal article; Peer reviewed, 2024)In modeling of gas flow through porous media width adsorption, the thermodynamic properties of the adsorbed phase are usually approximated by those of the bulk liquid. Using non-isothermal, gaseous transport of moist air ... -
Thermoelectric Phenomena in Lithium Ion Batteries and Thermogalvanic Cells
(Doctoral theses at NTNU;2023:308, Doctoral thesis, 2023)Electrochemical cells are central in the shift towards green energy sources. Lithium-ion batteries have rapidly become one of the world’s leading energy storage technologies. Thermogalvanic cells can be used to convert ... -
Thermoelectric Power of Ion Exchange Membrane Cells Relevant to Reverse Electrodialysis Plants
(Journal article; Peer reviewed, 2019)A thermoelectric cell is designed and experiments are carried out in order to measure Seebeck coefficients of ion exchange membranes at different constant concentrations of NaCl in water. The purpose of the investigation ... -
Thermoelectric Properties of Non-Aqueous Electrochemical Cells - Local Reversible Heat Effects Relevant for Lithium Ion Batteries
(Master thesis, 2018)The aim of this thesis was to investigate the thermoelectric properties and local reversible heat effects of cells relevant to lithium-ion batteries. The theory of non-equilibrium thermodynamics and experimental measurements ... -
Thermoelectrochemical Cell with Molten Carbonate Electrolyte
(Journal article, 2017)Industrial processes for production of metals and alloys by metallurgical and electrochemical methods generate a lot of heat due to irreversible losses. The waste heat should be used to generate electricity. Commercial ... -
Thickness Mediated Morphology Evolution in Sub-10-nm Metal Film Deposition: Implications for Non-destructive Testing
(Peer reviewed; Journal article, 2023)Thickness in sub-10-nm metal film deposition is a seldomly explored parameter that can influence not only the film mechanical properties but also the surface functional characteristics. In this study, we designed bilayer ... -
Thin film breakage in oil–in–water emulsions, a multidisciplinary study
(Peer reviewed; Journal article, 2022)Coalescence is a critical phenomenon in separation and transport processes. An improved understanding of coalescence can enhance current models predicting emulsion stability and separation. We here report a combined ... -
Total Mercury Distribution in the Barents Sea and the Arctic Ocean Surface Sediments
(Master thesis, 2022)Mercury (Hg) has been a trace metal of interest for decades due to its neurotoxic effects on humans and other organisms coupled with its ability to bioaccumulate and biomagnify. Areas like the Arctic and the ocean floor ... -
Total Synthesis and Semi Synthesis of Steroids: What is the best approach?
(Bachelor thesis, 2022)Steroider, komplekse molekyler med flere kirale sentre og en størrelsesorden av biokjemiske effekter, har vært i søkelyset for mange kjemikere siden 1940-tallet. På grunn av den økende etterspørselen av steroider for ... -
Total synthesis of Dothideopyrone E and Dothideopyone F
