(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Predicting the proximity of large-scale dynamic failure is a critical concern in the engineering and geophysical sciences. Here we use evolving contractive, dilatational, and shear strain deformation preceding failure in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Examining the deformation of rocks during triaxial compression may provide insights into the precursory phase that leads to large earthquakes by revealing the components of the deformation field that evolve with predictable, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Recently, the premelting and formation of ice due to the Casimir-Lifshitz interaction, proposed in early 1990s by Elbaum and Schick [Phys. Rev. Lett. 66, 1713 (1991)], have been generalized to diverse practical scenarios, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We have investigated the pressure (P) effect on structural (up to 10 GPa), transport [R(T): up to 10 GPa], and magnetic [(M(T): up to 1 GPa)] properties and analyzed the flux pinning mechanism of the Fe0.99Mn0.01Se0.5Te0.5 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Exhumed reservoirs providing evidence of CO2 accumulation and transport in geological history offer a unique possibility to supplement our knowledge on leakage processes observed along faults and fractures. A field location ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract A mechanism accommodating large strain in superplastic flow with elongation of 100%–300%, is described for fine‐grained calcareous shales deformed at temperature of 200–335°C and depths of 5–8 km up to slate schists ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Hydrostatic pressure response of LaAuSb2 charge density wave (CDW) system is investigated using electrical transport, x-ray diffraction (XRD), and density-functional theory (DFT). Resistivity data at ambient pressure ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The magnetic properties of iron chalcogenides and pnictides have found much interest as magnetic fluctuations are suggested to drive the formation of Cooper pairs in iron-based superconductors. Here, we have studied the ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)We report high-pressure structural studies (52 GPa) at room temperature combined with magnetic [(M(T):1GPa] and electrical resistivity [(ρ(T):0-21GPa)] measurements down to 2 K on Fe0.99Ni0.01Se0.5Te0.5 superconductor using ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)A steady-state photocapacitance (SSPC) setup directly connected to the beamline of a MeV ion implanter is utilized to study primary intrinsic defects in β–Ga2O3 generated by He implantation at cryogenic temperatures (120 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Feldspar-rich pseudotachylytes from the island of Moskenesøya, Lofoten, formed in dry granulites under lower crustal conditions during the Caledonian orogeny. The central parts of the pseudotachylytes, where the cooling ...
-
(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 ...
