(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Flexible metal–organic frameworks (MOFs) are known for their vast functional diversities and variable pore architectures. Dynamic motions or perturbations are among the highly desired flexibilities, which are key to guest ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)High-density structures of subsurface phosphorus dopants in silicon continue to garner interest as a silicon-based quantum computer platform; however, a much-needed confirmation of their dopant arrangement has been lacking. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We report the first nanoscale investigation of FeCoNi(AlMn)x high-entropy alloys (HEAs) processed by laser metal deposition. The structural evolution of the alloy upon chemical composition variation (0.2 ≤ x ≤ 1.5) was ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Fourteen alloys of the FeCoNiAlxMnx system were processed by laser metal deposition (LMD). The feedstock was a weighted and proportional blend of the containing elemental powders, targeting the nominal alloy compositions. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Background Machine learning (ML) methodology development for the classification of immune states in adaptive immune receptor repertoires (AIRRs) has seen a recent surge of interest. However, so far, there does not exist ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)Novel aluminum and indium doped zinc oxide (ZnO) bilayer transparent conducting oxide thin films was fabricated by simple sol-gel spin coating method and post-annealed at 500 °C for an hour under nitrogen ambient for solar ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Neutral shallow donors (D0) in ZnO have emerged as a promising candidate for solid-state spin qubits. Here we report on the formation of D0 in ZnO via implantation of In and subsequent annealing. The implanted In donors ...

Protracted localization of metamorphism and deformation in a heterogeneous lower-crustal shear zone (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Deformation of the continental crust is influenced by the pre-existing structural framework, fluid availability, strain rate, and pressure-temperature conditions. We investigate the evolution of a large (hundreds-of-meters ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)During continental collision, large tracts of crust are mobilized along major shear zones. The metamorphic conditions at which these zones operate, the duration of thrusting, and the deformation processes that facilitated ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)he surface protonic conductivity of porous monoclinic ZrO2 sintered at temperatures in the range 700–1100 °C yielding relative densities of around 60% and grain sizes of approximately 160 nm has been studied using impedance ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Metal–organic frameworks (MOFs) are nanoporous materials composed of organic linkers and inorganic nodes. The large variety of linkers and nodes and the multiple ways to combine them make MOFs highly tunable materials, ...
