(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Frost is damaging to plants when air temperature drops below their tolerance threshold. The set of mechanisms used by cold-tolerant plants to withstand freezing is called “hardening” and typically take place in autumn to ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Over the last few years, genomic studies on Yersinia pestis, the causative agent of all known plague epidemics, have considerably increased in numbers, spanning a period of about 5,000 y. Nonetheless, questions concerning ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Peritoneal malignant mesothelioma is a rare disease with a generally poor prognosis and poor response to chemotherapy. To improve survival there is a need for increased molecular understanding of the disease, including ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Ion implantation is a commonly used process step in 4H-SiC device manufacturing to implement precise concentrations of dopant atoms in selected areas and depths. This paper reports on vanadium (V) implantation into ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Channeling phenomena during ion implantation have been studied for 50 keV 11 B, 100 keV 27 Al and 240 keV 71 Ga in 4H-SiC by secondary ion mass spectrometry and medium energy ion backscattering. The same projected range ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)We herein report inter-diffusion across the interface between p-type Ni0.98Li0.02O and n-type Zn0.98Al0.02O for various applications including p-n-heterojunction diodes and oxide thermoelectrics. Diffusion couples were ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Climate change will affect the population dynamics of many species, yet the consequences for the long-term persistence of populations are poorly understood. A major reason for this is that density-dependent feedback effects ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Ion irradiation is a powerful tool to tune properties of semiconductors and, in particular, of gallium oxide (Ga 2 O 3 ) which is a promising ultra-wide bandgap semiconductor exhibiting phase instability for high ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Positron annihilation spectroscopy, Fourier transform-infrared absorption spectroscopy, and secondary ion mass spectrometry have been used to study the behavior of gallium vacancy-related defects and hydrogen in deuterium ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)We report on the structural, magnetic and electronic properties of Rh substituted LaNiO3, LaNi1–xRhxO3 (0 ≤ x ≤ 1). Increased Rh contents are associated with increased structural distortion, and we observe a phase ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)A new model for hydrogen-assisted fatigue crack growth (HAFCG) in BCC iron under a gaseous hydrogen environment has been established based on various methods of observation, i.e., electron backscatter diffraction (EBSD), ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The first known interstellar object 'Oumuamua exhibited a nongravitational acceleration that appeared inconsistent with cometary outgassing, leaving radiation pressure as the most likely force. Barring the alien lightsail ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We characterize and monitor subsidence of the Bursa Plain (southern Marmara region of Turkey), which has been interpreted as resulting from tectonic motions in the region. We quantify the subsidence using Interferometric ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Digital volume correlation analysis of time‐resolved X‐ray microtomography scans acquired during in situ triaxial compression of Green River shale cores provided time series of 3‐D incremental strain fields that elucidated ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In this work, an in-situ growth approach has been employed to fabricate Al:ZnO/Cu2O/Cu and Al:ZnO/ZnO/Cu2O/Cu heterojunctions using direct current (DC) and radio frequency (RF) magnetron sputtering technique in a controlled ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The electrical and chemical properties of the titanium dioxide (TiO2) coated spirals grown by the atomic layer deposition (ALD) technique in two different temperatures of 150 °C and 300 °C are studied. The thickness of the ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)We apply inline electron holography to investigate the electrostatic potential across an individual BaZr0.9Y0.1O3 grain boundary. With holography, we measure a grain boundary potential of −1.3 V. Electron energy loss ...
