In-plane structural order of domain engineered La0.7Sr0.3MnO3 thin films
(Journal article, 2013)We present a detailed structural study of tensile-strained La0.7Sr0.3MnO3 thin films. We use the substrate miscut to control the number of rhombohedral variants in the films and study the in-plane order and structural ... -
Effect of polar (111)-oriented SrTiO3 on initial perovskite growth
(Journal article, 2016)In crystalline thin film growth a prerequisite is substrate surfaces with a stable and uniform structure and chemical composition. Various substrate treatments were used to obtain atomically smooth, step-and-terrace ... -
Adsorption of Carbon Dioxide on Mono-Layer Thick Oxidized Samarium Films on Ni(100)
(Peer reviewed; Journal article, 2021)Studies of adsorption of CO2 on nanoscopic surfaces are relevant for technological applications in heterogeneous catalysis as well as for sorption of this important greenhouse gas. Presently, adsorption of carbon dioxide ... -
Benchmarking microbarom radiation and propagation model against infrasound recordings: a vespagram-based approach
(Journal article; Peer reviewed, 2021)This study investigates the use of a vespagram-based approach as a tool for multi-directional comparison between simulated microbarom soundscapes and infrasound data recorded at ground-based array stations. Data recorded ... -
Diffractive X-ray Tomography of Oriented Mineralized Structures Doctoral thesis in Hierarchical Materials
(Doctoral theses at NTNU;2021:112, Doctoral thesis, 2021)Many materials around us in everyday life have a hierarchical structure, meaning that defining structural features are found at multiple length scales, often ranging from the molecular to the macroscopic scale, together ... -
A system for the high-throughput measurement of the shear modulus distribution of human red blood cells
(Peer reviewed; Journal article, 2020)Reduced deformability of red blood cells (RBCs) can affect the hemodynamics of the microcirculation and reduce oxygen transport efficiency. It is also well known that reduced RBC deformability is a signature of various ... -
High-Energy Neutrino and Gamma-Ray Emission from Tidal Disruption Events
(Peer reviewed; Journal article, 2020)Tidal disruption events (TDE) have been considered as cosmic-ray and neutrino sources for a decade. We suggest two classes of new scenarios for high-energy multi-messenger emission from TDEs that do not have to harbor ... -
3HSP J095507.9+355101: A flaring extreme blazar coincident in space and time with IceCube-200107A
(Peer reviewed; Journal article, 2020)The uncertainty region of the highly energetic neutrino IceCube200107A includes 3HSP J095507.9+355101 (z = 0.557), an extreme blazar, which was detected in a high, very hard, and variable X-ray state shortly after the ... -
Perfect depolarization in single scattering of light from uncorrelated surface and volume disorder
(Journal article, 2020)-polarized waves from uncorrelated surface and volume disorder can lead to perfect depolarization. The degree of polarization vanishes in specific scattering directions that can be characterized based on simple geometric ... -
Density functional simulations of pressurized Mg-Zn and Al-Zn alloys
(Peer reviewed; Journal article, 2020)Binary Mg-Zn and Al-Zn alloys have been investigated theoretically under static isotropic pressure. The stable phases of these binaries on both initially hexagonal-close-packed (hcp) and face-centered-cubic (fcc) lattices ... -
Josephson effect in graphene bilayers with adjustable relative displacement
(Peer reviewed; Journal article, 2020)The Josephson current is investigated in a superconducting graphene bilayer where pristine graphene sheets can make in-plane or out-of-plane displacements with respect to each other. The superconductivity can be of an ... -
Strain-engineered widely tunable perfect absorption angle in black phosphorus from first principles
(Peer reviewed; Journal article, 2020)Using the density functional theory of electronic structure, we compute the anisotropic dielectric response of bulk black phosphorus subject to strain. Employing the obtained permittivity tensor, we solve Maxwell’s equations ... -
Density functional and classical simulations of liquid and glassy selenium
(Peer reviewed; Journal article, 2020)Molecular dynamics simulations of liquid and glassy selenium have been carried out using density functional (400–773 K, 600 atoms) and classical force field (290–500 K, 5488 atoms) methods. Structural features (structure ... -
Precipitate formation in aluminium alloys: Multi-scale modelling approach
(Peer reviewed; Journal article, 2020)Ternary Al–Mg–Si alloys have been modelled based on a multi-scale approach that spans across atomistic and mesoscale models and uses theoretically determined parameters. First, a cluster expansion model for total energy ... -
Impacts of UV irradiance and medium-energy electron precipitation on the North Atlantic oscillation during the 11-year solar cycle
(Peer reviewed; Journal article, 2021)Observational studies suggest that part of the North Atlantic Oscillation (NAO) variability may be attributed to the spectral ultra-violet (UV) irradiance variations associated to the 11-year solar cycle. The observed ... -
Modified embedded atom method potential for Fe-Al intermetallics mechanical strength: A comparative analysis of atomistic simulations
(Peer reviewed; Journal article, 2021)The structural and mechanical properties of Fe-Al compounds (FeAl, FeAl, FeAl, FeAl, FeAl, FeAl) have been studied using modified embedded atom method (MEAM) potentials. The equilibrium lattice constants, formation enthalpies, ... -
Stretching, breaking, and dissolution of polymeric nanofibres by computer experiments
(Doctoral theses at NTNU;2021:176, Doctoral thesis, 2021)Bundles of polymeric materials are ubiquitous and play essential roles in biological systems, and often display remarkable mechanical properties. With the never-ending experimental advances in control and manipulation of ... -
Biodistribution of Poly(alkyl cyanoacrylate) Nanoparticles in Mice and Effect on Tumor Infiltration of Macrophages into a Patient-Derived Breast Cancer Xenograft
