Transport in Magnetic and Superconducting Heterostructures
(Doctoral theses at NTNU;2021:374, Doctoral thesis, 2021)In essence, spintronics aims to utilize the spins of electrons to store and process information, either as a supplement to or as a replacement for electron charges. Electron spins are particularly suitable for use in ... -
Transport of Nitric Oxide Via Lagrangian Coherent Structures Into the Top of the Polar Vortex
(Peer reviewed; Journal article, 2021)The energetic particle precipitation (EPP) indirect effect (IE) refers to the downward transport of reactive odd nitrogen (NOx = NO + NO2) produced by EPP (EPP-NOx) from the polar winter mesosphere and lower thermosphere ... -
Transport on a nanoscale; quasi-elastic neutron scattering and molecular dynamic studies
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:60, Doctoral thesis, 2009)The objective of this thesis was to investigate how hydrogen is transported in the polymer electrolyte membrane fuel cell (PEMFC) electrodes. We wanted to investigate if the graphitic catalyst support material can contribute ... -
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 ... -
Transportable double-sided laser heating setup with variable configuration for in-situ synchrotron X-Ray diffraction, X-ray Transmission Microscopy and multimegabar pressure DACs experiments
(Journal article; Peer reviewed, 2019)The diamond anvil cell (DAC) technique combined with laser heating is one of the major methods for studying materials at high pressure and high temperature conditions. In this work, we present a transferable double-sided ... -
Transporterer atmosfæriske bølger polarlysprodusert NO ned til den midtre atmosfæren
(Master thesis, 2016)Hensikten med denne studien var å undersøke potensielle mekanismer bak observerte nivåer av NO-gass i mesosfæren på høyder mellom 60 og 80 kilometer. Tre hypoteser ble formulert og undersøkt i denne sammenheng. Lokal ... -
Traveling planetary wave activity from mesopause region airglow temperatures determined by the Network for the Detection of Mesospheric Change (NDMC)
(Journal article; Peer reviewed, 2014)The global distribution of traveling planetary wave (PW) activity in the mesopause region is estimated for the first time from ground-based airglow measurements. Monthly and total mean climatologies of PW power are determined ... -
