(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)In this work we benefited from recent advances in tools for crystal‐structure analysis that enabled us to describe an exotic nanoscale phenomenon in structural chemistry. The Mn0.60Ni0.40As sample of the Mn1−xNixAs solid ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The diffusion of saturated and unsaturated hydrocarbons is of fundamental importance for many zeolite-catalyzed processes. Transport of small alkenes in the confined zeolite pores can become hindered, resulting in a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The chalcopyrite Cu(In,Ga)S2 has gained renewed interest in recent years due to the potential application in tandem solar cells. In this contribution, a combined theoretical and experimental approach is applied to investigate ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Volcanic eruptions pose a threat to lives and property when volcano flanks and surroundings are densely populated. The local impact of an eruption depends firstly on its location, whether it occurs near a volcano summit, ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)The mechanisms triggering intermediate and deep earthquakes have puzzled geologists for several decades. There is still no consensus concerning whether such earthquakes are triggered by brittle or ductile mechanisms. We ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The evolution of electrical resistance as function of defect concentration is examined for the unipolar n-conducting oxides CdO, β-Ga2O3, In2O3, SnO2 and ZnO in order to explore the predictions of the amphoteric defect ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)A 2D Hele-Shaw cell was built to study microfracture nucleation, growth, and network formation during internal fluid production. Fluid is slowly produced into a low permeability solid, which leads to a local fluid pressure ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Reaction-infiltration instability refers to the morphological instability of a reactive fluid front flowing in a soluble porous medium. This process is important for many naturally occurring phenomena, such as the weathering ...
