Impact of the major SSWs of February 2018 and January 2019 on the middle atmospheric nitric oxide abundance
(Peer reviewed; Journal article, 2021)The Arctic middle atmosphere was affected by major sudden stratospheric warmings (SSW) in February 2018 and January 2019, respectively. In this article, we report for the first time the impact of these two events on the ... -
Sonopermeation Enhances Uptake and Therapeutic Effect of Free and Encapsulated Cabazitaxel
(Peer reviewed; Journal article, 2021)Delivery of drugs and nanomedicines to tumors is often heterogeneous and insufficient and, thus, of limited efficacy. Microbubbles in combination with ultrasound have been found to improve delivery to tumors, enhancing ... -
Effect of nitrogen pressure and substrate bias voltage on the properties of Al–Cr–B–N coatings deposited using cathodic arc evaporation
(Peer reviewed; Journal article, 2021)Cathodic arc evaporation deposition method was applied to forming Al–Cr–B–N coatings. The effect of nitrogen pressure (pN2) and substrate bias voltage (UB) on the properties of the coatings synthesized using Al50Cr30Br20 ... -
A Perturbation Analysis Approach for Studying the Effect of Swelling Kinetics on Instabilities in Hydrogel Plates
(Journal article; Peer reviewed, 2021)The onset of surface instability during diffusion-driven swelling of hydrogels depends on the kinetics of the swelling process. Here, we outline a perturbation analysis framework using a finite difference approach for ... -
Effect of acoustic radiation force on displacement of nanoparticles in collagen gels
(Peer reviewed; Journal article, 2020)Penetration of nanoscale therapeutic agents into the extracellular matrix (ECM) of a tumor is a limiting factor for the sufficient delivery of drugs in tumors. Ultrasound (US) in combination with microbubbles causing ... -
Aging and Failure of a Polymer Chain under Tension
(Peer reviewed; Journal article, 2021)The rupture of a polymer chain maintained at temperature T under fixed tension is prototypical to a wide array of systems failing under constant external stress and random perturbations. Past research focused on analytic ... -
Convergence of Ensemble Simulations for Environmental Risk Assessment
(Chapter, 2017)Ensemble simulations of oil fate and transport for a hypothetical oil spill, sometimes referred to as "stochastic simulations", are frequently used for environmental risk assessment related to offshore operations. In this ... -
Climate Change and Fate of Arctic Oil Spills
(Chapter, 2017)To investigate how the fate of oil released in the Arctic Ocean may change with a warmer climate, we have performed ensembles of oil spill simulations using Arctic environmental information (winds, currents, ice cover, ... -
First-principles study of tensile and shear strength of an Fe2Al5//Fe interface
(Peer reviewed; Journal article, 2021)The interfacial strengths of a low misfit Fe2Al5//Fe interface structure found at aluminum-steel joints has been studied using density functional theory. An interface between Fe and Fe2Al5 was selected based on a criteria ... -
Biological lipid nanotubes and their potential role in evolution
(Peer reviewed; Journal article, 2020)The membrane of cells and organelles are highly deformable fluid interfaces, and can take on a multitude of shapes. One distinctive and particularly interesting property of biological membranes is their ability to from ... -
A technique for in situ X-ray computed tomography of deformation-induced cavitation in thermoplastics
(Peer reviewed; Journal article, 2020)Deformation-induced cavitation influences the mechanical response of polymeric materials, but acquiring in situ measurements of the spatial evolution of cavities has typically necessitated the use of synchrotron radiation ... -
Smart cancer nanomedicine
(Peer reviewed; Journal article, 2019)Nanomedicines are extensively employed in cancer therapy. We here propose four strategic directions to improve nanomedicine translation and exploitation. (1) Patient stratification has become common practice in oncology ... -
Fluid flow through 3D-printed particle beds: a new technique for understanding, validating, and improving predictability of permeability from empirical equations
(Peer reviewed; Journal article, 2020)The application of 3D technology for fabrication of artificial porous media samples improves porous media flow studies. The geometrical characteristics of a porous media pore channel: the channel shape, size, porosity, ... -
Epitaxial (100), (110), and (111) BaTiO3 films on SrTiO3 substrates — A transmission electron microscopy study
(Peer reviewed; Journal article, 2021)Chemical solution deposition (CSD) is a versatile method to fabricate oxide films. Here, the structure and local variations in the chemical composition of BaTiO3 (BTO) films prepared by CSD on (100), (110), and (111) SrTiO3 ... -
Crack localization and the interplay between stress enhancement and thermal noise
(Peer reviewed; Journal article, 2021)We study the competition between thermal fluctuations and stress enhancement in the failure process of a disordered system by using a local load sharing fiber bundle model. The thermal noise is introduced by defining a ... -
Fluid Meniscus Algorithms for Dynamic Pore-Network Modeling of Immiscible Two-Phase Flow in Porous Media
(Peer reviewed; Journal article, 2021)We present in detail a set of algorithms for a dynamic pore-network model of immiscible two-phase flow in porous media to carry out fluid displacements in pores. The algorithms are universal for regular and irregular pore ... -
Hyperballistic Superdiffusion and Explosive Solutions to the Non-Linear Diffusion Equation
(Peer reviewed; Journal article, 2021)By means of a particle model that includes interactions only via the local particle concentration, we show that hyperballistic diffusion may result. This is done by finding the exact solution of the corresponding non-linear ... -
Micro-scale studies of microbialinduced carbonate precipitation for the application of biocementation
(Doctoral theses at NTNU;2021:59, Doctoral thesis, 2021)Cement, which is used as a binding material in conventional concrete, is the second most consumed material by humans, after water. The production process of cement, however, causes a high emission of CO2 and contributes ... -
Electrochemical modification of the Ti-15Mo alloy surface in solutions containing ZnO and Zn3(PO4)2 particles
(Peer reviewed; Journal article, 2020)This paper reports on the plasma electrolytic oxidation (PEO) of titanium alloy Ti-15Mo in baths containing zinc to obtain biomaterials with bacteriostatic and antibacterial properties. The Ti-15Mo surface was oxidised in ... -
