(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 ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)In this study structural and mechanical properties of a 1 μm thick Al2O3 coating, deposited on 316L stainless steel by Pulsed Laser Deposition (PLD), subjected to high energy ion irradiation were assessed. Mechanical ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Centrality, which quantifies the importance of individual nodes, is among the most essential concepts in modern network theory. As there are many ways in which a node can be important, many different centrality measures ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Spectroscopic identification of defects and impurities is crucial for understanding doping asymmetry issues in ZnO and, therefore, realization of true ZnO-based bipolar devices. Chlorine (Cl) is an amphoteric impurity in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Abstract Advances in next-generation sequencing technology have enabled whole genome sequencing (WGS) to be widely used for identification of causal variants in a spectrum of genetic-related disorders, and provided new ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Methylation of aromatic compounds is a key reaction step in various industrial processes such as the aromatic cycle of methanol-to-hydrocarbons chemistry. The study of isolated methylation reactions and of the influence ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract The seismic waves emitted during granular flows are generated by different sources: high frequencies by interparticle collisions and low frequencies by global motion and large scale deformation. To unravel these ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)Silicon (Si) is an efficient n-type dopant in gallium oxide (Ga2O3)—an ultra-wide bandgap semiconductor promising in a number of applications. However, in spite of the technological importance for device fabrication, the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Centrality, which quantifies the “importance” of individual nodes, is among the most essential concepts in modern network theory. Most prominent centrality measures can be expressed as an aggregation of influence flows ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Li-ion capacitors (LICs) are designed to achieve high power and energy densities using a carbon-based material as a positive electrode coupled with a negative electrode often adopted from Li-ion batteries. However, such ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)In all implantations into crystalline targets, quite a few ions find a path along a crystal channel or plane, so called channeling, and these ions travel deep into the crystal. This paper treats aluminum (Al) implantation ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Silver alloying of Cu(In,Ga)Se2 absorbers for thin film photovoltaics offers improvements in open-circuit voltage, especially when combined with optimal alkali-treatments and certain Ga concentrations. The relationship ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Magma intrusions grow to their final geometries by deforming the Earth's crust internally and by displacing the Earth's surface. Interpreting the related displacements in terms of intrusion geometry is key to forecasting ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)We present an analytical solution based on the series expansion of Papkovich-Boussinesq's displacement potentials to derive the elastic solution of a spherical inclusion containing an eigenstrain or pressurized cavity in ...
