(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Reliable Life Cycle Assessment (LCA) of processes for valorization of CO2-rich off-gas streams requires multidisciplinary contributions that span the development of active and selective catalysts, reactor design, plant ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2020)The phase-field crystal model in an amplitude equation approximation is shown to provide an accurate description of the deformation field in defected crystalline structures, as well as of dislocation motion. We analyze in ...

A comprehensive framework for analysis of microRNA sequencing data in metastatic colorectal cancer (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)ABSTRACT Although microRNAs (miRNAs) contribute to all hallmarks of cancer, miRNA dysregulation in metastasis remains poorly understood. The aim of this work was to reliably identify miRNAs associated with ...
-
A Consistent Framework for Coupling Basal Friction With Subglacial Hydrology on Hard-Bedded Glaciers (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Below hard-bedded glaciers, both basal friction and distributed subglacial drainage are thought to be controlled by a network of cavities. Previous coupled hydro-mechanical models, however, describe cavity-driven friction ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Near-surface remote sensing techniques are essential monitoring tools to provide spatial and temporal resolutions beyond the capabilities of orbital methods. This high level of detail is especially helpful to monitor ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Plague continued to afflict Europe for more than five centuries after the Black Death. Yet, by the 17th century, the dynamics of plague had changed, leading to its slow decline in Western Europe over the subsequent 200 y, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We review and extend a hierarchy of relaxation models for two-phase flow. The models are derived from the non-equilibrium Baer–Nunziato model, which is endowed with relaxation source terms to drive it towards equilibrium. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract It is well known that multicomponent catalysts can improve catalytic performance, however their rational design and precise control of catalytic activities by varying the composition of the elements is challenging. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Surge-type glaciers are present in many cold environments in the world. These glaciers experience a dramatic increase in velocity over short time periods, the surge, followed by an extended period of slow movement, the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract The use of diaryliodonium salts in organic reactions has rapidly increased in the last decade because of their efficiency in arylation reactions. Despite this, mechanistic investigations are still scarce, particularly ...
-
A new software implementation of the Oslo method with rigorous statistical uncertainty propagation (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The Oslo method comprises a set of analysis techniques designed to extract nuclear level density and average -decay strength function from a set of excitation-energy tagged -ray spectra. Here we present a new software ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)This study presents the novel peridynamic constitutive relations formulated in order to predict the plastic deformation and damage evolution in irradiated materials. The plastic behaviour of the material in which radiation ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We introduce a dislocation density tensor and derive its kinematic evolution law from a phase field description of crystal deformations in three dimensions. The phase field crystal (PFC) model is used to define the lattice ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Biocementation is commonly based on microbial-induced carbonate precipitation (MICP) or enzyme-induced carbonate precipitation (EICP), where biomineralization of CaCO3 in a granular medium is used to produce a sustainable, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Liquid-filled corners and capillary bridges can establish networks connecting seemingly isolated clusters during drainage in porous media. Coupled with drainage through the bulk of pores and throats, the flow through these ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Herein, we report the discovery of a toroidal inorganic cluster of zirconium(IV) oxysulfate of unprecedented size with the formula Zr70(SO4)58(O/OH)146⋅x(H2O) (Zr70), which displays different packing of ring units and thus ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Topological defects and smooth excitations determine the properties of systems showing collective order. We introduce a generic non-singular field theory that comprehensively describes defects and excitations in ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Transition metal containing polyanion compounds are effective excellent electrode materials for sodium-ion batteries due to their high intrinsic electrochemical potentials and to the resulting high energy density. Iron ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Melting curves of Ca-perovskite (pure CaSiO3) were determined by ab initio density functional theory, using two solid-liquid coexistence methods and two free energy approaches, in the form of thermodynamic integration and ...
