Transport phenomena in a temperaturegradient studied by NEMD. A chemical reaction and a phase transition
(Doctoral Theses at NTNU, 1503-8181; 2009:193, Doctoral thesis, 2009)In this thesis we used non-equilibrium molecular dynamics (NEMD) to study non-equilibrium behaviors of two irreversible systems, both exposed to large temperature gradients. As modeling systems, we have chosen a simple ... -
Transport Properties of the Simple Lennard-Jones/Spline Fluid I: Binary Scattering and High-Accuracy Low-Density Transport Coefficients
(Peer reviewed; Journal article, 2020)Inspired by recent work on the thermodynamic properties of the Lennard-Jones/spline (LJ/s) fluid [1], we have considered the transport properties of the simple LJ/s fluid. The binary scattering problem for LJ/s particles ... -
Treatment and monitoring of polluted leakage water from the former Killingdal concentration plant area in Trondheim - Comparable studies of olivine and lime in a semi-scale water treatment system.
(Master thesis, 2020)Killingdal er et område i Trondheim hvor et tidligere flotasjonsverk som behandlet pyritt, sinkblende, og kobberpyritt var aktivt fra 1953 til 1986. Når gruveaktivitet stopper vil rester fra gruvedriften ligge igjen, og ... -
Treatment of Large-Scale Systems with Multiscale and Fragmentation Methods
(Bachelor thesis, 2022)Kvantekjemiske beregning er i dag et stort og viktig felt innen kjemi, og har vært viktigere de siste årene ettersom beregningsteknologien har utviklet seg. Imidlertid er det fortsatt mange utfordringer innenfor dette ... -
Tunable Gold-catalyzed Reactions of Propargyl Alcohols and Aryl Nucleophiles
(Peer reviewed; Journal article, 2022)Gold-catalyzed transformations of 1,3-diarylpropargyl alcohols and various aryl nucleophiles were studied. Selective tunable synthetic methods were developed for 1,1,3-triarylallenes, diaryl-indenes and tetraaryl-allyl ... -
Tungmetallavrenning til Folla, studier av lokale kilder. Langtidstrender for vassdraget.
(Master thesis, 2021)Denne masteroppgaven tar for seg Folldal Verk og forurensninger knyttet til avrenning fra nedlagte gruver og velt. Folldal Verk er delt inn i to områder: Tverrfjellet gruve på Hjerkinn og gruvene ved Folldal sentrum. Nedfor ... -
Tungmetaller i bekken Søra i Trondheim kommune
(Master thesis, 2018)I denne studien av bekken Søra blir konsentrasjoner av prioriterte tungmetaller og fosfor presentert for både filtrerte og ufiltrerte prøver. Bekken er betydelig påvirket av forurensning og leire, og Bekken har hatt en ... -
Tuning the Electronic Properties of Single-Atom Pt Catalysts by Functionalization of the Carbon Support Material
(Journal article; Peer reviewed, 2017)When using support materials in heterogeneous catalysis, a fundamental understanding of the interactions between the catalyst and the support material is of critical importance. In this work, the stability, electronic ... -
"Two hits - one stone" increased efficacy of cisplatin-based therapies by targeting PCNA's role in both DNA repair and cellular signaling
(Journal article; Peer reviewed, 2018)Low response rate and rapid development of resistance against commonly used chemotherapeutic regimes demand new multi-targeting anti-cancer strategies. In this study, we target the stress-related roles of the scaffold ... -
Two-Phase Equilibrium Conditions in Nanopores
(Peer reviewed; Journal article, 2020)It is known that thermodynamic properties of a system change upon confinement. To know how, is important for modelling of porous media. We propose to use Hill’s systematic thermodynamic analysis of confined systems to ... -
Ultra-robust icephobic coatings with high toughness, strong substrate adhesion and self-healing capability
(Peer reviewed; Journal article, 2022)Enabling surfaces with passive anti-icing properties is an emerging, facile, economical, and energy-saving strategy to mitigate the harm caused by ice accretion. However, the combination of icephobicity and robustness still ... -
