(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Atomic layer deposition (ALD) is a thin film synthesis technique that can provide exquisite accuracy and precision in film thickness and composition even on complex, large area substrates. Based on self-limiting surface ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)We introduce a shear experiment that quantitatively reproduces the main laws of seismicity. By continuously and slowly shearing a compressed monolayer of disks in a ringlike geometry, our system delivers events of frictional ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We have investigated how layered structures of TiO2 and Eu2O3 on the subnanometer scale control the optical absorption, energy transfer, emission and quenching mechanisms in sensitized lanthanide luminescence systems. By ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Oxide-containing films were made by reactively sputtering a high-entropy alloy target of CrFeCoNiCu. We report on a wide range of changes to the electrical properties made by different heat treatments in oxidizing and ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)The successful synthesis of metal−organic framework (MOF) compounds relies on an intricate interplay between the components of the synthesis liquor at the given synthesis conditions. Herein, we explore the interdependence ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The development of defect populations after proton irradiation of n-type 4H-SiC and subsequent annealing experiments is studied by means of deep level transient (DLTS) and photoluminescence spectroscopy. A comprehensive ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)A series of gas-phase reactants is used to treat a Cu-exchanged mordenite zeolite with the aim of studying the influence of the reaction environment on the formation of Cu pairs. The rearrangement of Cu ions to form ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Direct conversion of methane to methanol (MTM) over Cu-zeolites is a so-called “dream reaction” for the chemical industry. There is still a lot that can be done in order to optimize the reaction by e.g. achieving ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We report on a deep level transient spectroscopy study of annealing kinetics of a deep, vacancy-hydrogen related level, labeled E5* , at 0.42 eV below the conduction band in hydrogen-implanted n-type silicon. The E5* ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Process conditions during catalytic reactions induce significant changes in surface chemistry and structure of bi- (mono) metallic nanoparticles leading to their deactivation, and this can ultimately affect the reactions ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The Collisional Orogeny in the Scandinavian Caledonides (COSC) scientific drilling project aims to characterise the structure and orogenic processes involved in a major collisional mountain belt by multidisciplinary ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Tabular intrusions are common features in the Earth's brittle crust. They exhibit a broad variety of shapes, ranging from thin sheet intrusions (sills, saucer-shaped sills, cone sheets), to more massive intrusions (domed ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Calcium carbonate and cadmium-rich fluid interactions have been studied at the nano and microscale with fluid flow and static fluid conditions for three forms of CaCO3: calcite in single crystals of Iceland Spar, calcite ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Ensuring global food security and environmental sustainability is dependent upon the contribution of the world’s hundred million smallholder farms, but the contributions of smallholder farms to global agricultural greenhouse ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Electronic phase separation is a frequent ingredient of the physics of manganites for which the colossal magnetoresistance (CMR) phenomenon is at debate. We investigate the switchable magnetoresistance (MR) effect of the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The study of dynamically propagating rupture along interfaces is of prime importance in various fields and system sizes, including tribology (nm to μm), engineering (mm to m) and geophysics (m to km) (Armstrong-Hélouvry ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Introduction Pyle Disease (PD), or familial metaphyseal dysplasia [OMIM 265900], is a rare autosomal recessive condition leading to widened metaphyses of long bones and cortical bone thinning ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Faults in carbonate rocks show both seismic and aseismic deformation processes, leading to a wide range of slip velocities. We deformed two centimeter‐scale cores of Carrara marble at 25°C and imaged the nucleation and ...
