(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Air pollution implies significant threats for the human health and the surrounding environment. In recent years, a great deal of research has been carried out on the detection and removal of air pollutants through the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)gneous dykes are the main magma transport pathways through the Earth’s crust, and they are considered to mainly accommodate for tectonic extension in volcanic rifts. Dykes are typically considered to result from brittle ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Abstract Nanopillars of ZnO were implanted with Au-400 keV ions at various ion fluences from 1 × 10 15 cm −2 to 1 × 10 16 cm −2 and subsequently annealed at 750 °C for 15 min in order to reduce the implantation ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Zn interstitial (Zni) is one of the fundamental intrinsic defects in ZnO and prominently affects the physical properties of the material. Here, the energetics and migration properties of Zni have been studied in ion implanted ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2019)First-principles calculations have become a powerful tool to exclude the Edisonian approach in search of novel two-dimensional (2D) materials. However, no universal first-principles criteria to examine the realizability ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)It has over the last few years been reported that the application of a DC electric field and resulting current over a bed of certain catalyst-support systems enhances catalytic activity for several reactions involving ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)In order to guarantee the long-term efficiency of hydrophobic materials in real-world situations, it is necessary that their surfaces are highly resistant to scratching, fouling and misting. Furthermore, for the specific ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)In this paper, we investigate three different passivating films for use in predictable quantum efficient detectors: two monolayer films of SiNx with different compositions and one double-layer stack of SiNxOy capped with ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Chalcopyrite (CuFeS2) is the primary ore mineral for copper, but leaching of this mineral under atmospheric conditions is slow due to the formation of surface passivating phases such as elemental sulphur and jarosite. Here, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)High performance magnetocaloric materials are crucial to realize the energy efficient and environment friendly magnetic cooling/refrigeration technology. We have designed Mn1-xCuxCoGe compounds possessing a giant magnetocaloric ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The crystal quality and surface states are two major factors that determine optical properties of ZnO nanoparticles (NPs) synthesized through nonaqueous sol–gel routes, and both are strongly dependent on the growth conditions. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Entrepreneurship may be regarded as the mechanism of change towards sustainability. Any entrepreneur that seeks to start a new venture in an emerging industry will face resource and time constraints. The question we raise ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2013)The ichthyotoxic flagellate Pseudochattonella has formed recurrent blooms in the North Sea, Skagerrak and Kattegat since 1998. Five strains of Pseudochattonella farcimen and two strains of P. verruculosa were examined in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)It is shown how Maxwell’s equations for the electromagnetic field with Planck quantisation of allowed modes appears to provide a semiclassical account of nuclear interactions. The mesons emerge as plasmons, collective ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Plagioclase‐rich granulites exposed on the Lofoten archipelago, Northern Norway, display strain localization in pseudotachylytes as well as ductile shear zones that formed under similar high‐pressure and high‐temperature ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Functionalization of metal-organic frameworks (MOFs) with noble metals is a promising way for producing new versatile catalysts that will combine the outstanding porosity and specific surface area of MOFs with high catalytic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The experimental γ-ray strength functions (γSFs) of 142,144–151Nd have been studied for γ-ray energies up to the neutron separation energy using the Oslo method. The results represent a unique set of γSFs for an isotopic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Yersinia pestis is transmitted from fleas to rodents when the bacterium develops an extensive biofilm in the foregut of a flea, starving it into a feeding frenzy, or, alternatively, during a brief period directly after ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)This paper deals with a homogeneous Neumann problem of a nonlinear diffusion system involving variable exponents dependent on spatial and time variables and cross-diffusion terms. We prove the existence of weak solutions ...
