(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Abstract The Posada–Asinara Line is a crustal-scale transpressive shear zone affecting the Variscan basement in northern Sardinia during Late Carboniferous time. We investigated a structural transect of the Posada–Asinara ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Materials made of indium oxide (In2O3) are now being used as a potential component of the next generation of computers and communication devices. Density functional theory is used to analyze the physical, electrical, and ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Field and seismic observations show that numerous sills exhibit lobate morphologies. Each lobe corresponds to a distinct igneous segment exhibiting a finger-like shape, the long axis of which is commonly interpreted as a ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)We have measured water uptake and hydration enthalpy in 50% La and Nd doped CeO2, also to be taken as compositions in the series La2−xNdxCe2O7 (x = 0.0, 0.5, 1.0 and 2.0) using combined thermogravimetry (TG) and differential ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Sub-stochiometric nickel oxide (NiOx) films were investigated as a hole selective contact option in silicon (Si) heterojunction solar cells. Numerical simulations were carried out to evaluate the impacts of the NiOx ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Subduction initiation is a key in understanding the dynamic evolution of the Earth and its fundamental difference to all other rocky planetary bodies in our solar system. Despite recent progress, the question about how a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Subsea permafrost carbon pools below the Arctic shelf seas are a major unknown in the global carbon cycle. We combine a numerical model of sedimentation and permafrost evolution with simplified carbon turnover to ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Self-assembly of ordered nanometer-scale patterns is interesting in itself, but its practical value depends on the ability to predict and control pattern formation. In this paper we demonstrate theoretically and numerically ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Great genetic variability among teleost immunomes, with gene losses and expansions of central adaptive and innate components, has been discovered through genome sequencing over the last few years. Here, we demonstrate that ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Sunlight-driven photocatalytic degradation is an effective and eco-friendly technology for the removal of organic pollutants from contaminated water. Herein, we describe the one-step synthesis of Cu-Cu2O-Cu3N nanoparticle ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We present a study of the surface effects and optical properties of the self-assembled nanostructures comprised of vertically aligned 5 nm-diameter Al nanowires embedded in an amorphous Si matrix (a-Si:Al). The controlled ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)CeO2 surfaces play decisive roles in heterogeneous catalysis of important processes. Here, we investigate adsorption and dissociation of water and migration of protons on internal surfaces of nanoscopic porous CeO2. Sorption ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The reactivity of BaZr1−xYxO3−δ (x = 0–0.2) ceramics under 1 atm CO2 at 650 °C for up to 1000 h was investigated in order to elucidate possible degradation processes occurring when the material is applied as a proton-conducting ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract. Permafrost degradation in steep rock walls and associated slope destabilization have been studied increasingly in recent years. While most studies focus on mountainous and sub-Arctic regions, the occurring ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)Single-phase rock-salt CdZnO films were synthesized on r-plane sapphire substrates by metal–organic chemical vapor deposition. Evolutions in growth orientations were investigated in these films as a function of Zn content ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Symmetry breaking is observed in the Soai reaction in a confinement environment provided by zirconium-based UiO-MOFs used as crystalline sponges. Subsequent reaction of encapsulated Soai aldehyde with Zn(i-Pr)2 vapour ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Three-center, four-electron bonds provide unusually strong interactions; however, their nature remains ununderstood. Investigations of the strength, symmetry and the covalent versus electrostatic character of three-center ...
