(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The isomorphic insertion of cobalt(II) confers strong acidity to the AlPO-18 zeotype. This makes it a suitable catalyst for the acid catalysed conversion of methanol to olefins (MTO). However, due to the tendency of Co(II) ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Gold catalysis has become one of the fastest growing fields in chemistry, providing new organic transformations and offering excellent chemoselectivities under mild reaction conditions. Methodological developments have ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Cyclometalated gold(III) complexes Au(L)(OAcF)2 (L = phenylpyridine dicarboxylic diester (ppyde) or phenylpyridine dicarboxylic acid (ppydc)) have been prepared reacting Au(OAc)3 with corresponding phenyl pyridines (ppyde ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Boreal lakes are the most abundant lakes on Earth. Changes in acid rain deposition, climate, and catchment land use have increased lateral fluxes of terrestrial dissolved organic matter (DOM), resulting in a widespread ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Structural, morphological, and optical properties of (In1−xGax)2O3 thin films are reported as a function of the cation composition. A material library with 0.1≤x≤0.64 was fabricated by discrete combinatorial synthesis on ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Mordenite (MOR) zeolite, an important industrial catalyst exists in two, isostructural variants defined by their port-size, small and large-port. Here we show for the first time how a systematic, single-parameter variation ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)The nature of intrinsic defects in ZnO films grown by metal organic vapor phase epitaxy was studied by positron annihilation and photoluminescence spectroscopy techniques. The supply of Zn and O during the film synthesis ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)We present long-term changes in Norwegian lake water quality across regional gradients in atmospheric pollution, air temperature, hydrology, and vegetation using (a) a national representative lake survey carried out in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Increased risk-taking is a central component of bipolar disorder (BIP) and is implicated in schizophrenia (SCZ). Risky behaviours, including smoking and alcohol use, are overrepresented in both disorders and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Zinc Oxynitride (ZnOxNy) thin films display high mobilities and a considerable tunability of both the free electron concentration and optical band gap. The properties achievable for this material system makes ZnOxNy an ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Flavodoxins (Flds) are small, bacterial proteins that transfer electrons to various redox enzymes. Flavodoxins are reduced by ferredoxin/flavodoxin NADP+ oxidoreductases (FNRs), but little is known of the FNR-Fld interaction. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)This paper presents an innovative experimental setup that employs the principles of audio technology to subject adherent cells to rhythmic vertical vibrations. We employ a novel approach that combines three-axis acceleration ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2019)Last year, we reported a perturbative theory of the Casimir-Lifshitz torque between planar biaxially anisotropic materials in the retarded limit [Thiyam et al., Phys. Rev. Lett. 120, 131601 (2018)], which is applied here ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Point defects in silicon carbide (SiC) are well positioned for integration with SiC based quantum photonic devices due to the maturity of SiC material and fabrication technology, the plethora of candidate quantum emitters ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Heterogeneous doping through nanostructuring has been demonstrated to greatly enhance the transport and mass storage properties of halides and Li-ion conductors by decoupling of charge-compensating species. In this study, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)A chiral spin liquid state is discovered in the highly frustrated, noncentrosymmetric swedenborgite compound YBaCo3FeO7, a layered kagome system of hexagonal symmetry, by advanced polarized neutron scattering from a single ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)We study the hydrodynamic forces acting on a small impurity moving in a two-dimensional Bose–Einstein condensate at non-zero temperature. The condensate is modelled by the damped-Gross Pitaevskii (dGPE) equation and the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Surveys have long been used in physics education research to understand student reasoning and inform course improvements. However, to make analysis of large sets of responses practical, most surveys use a closed-response ...
-
