Orientation relationship between b-Si3N4 and Si in multicrystalline silicon ingots for PV applications
(Journal article; Peer reviewed, 2018)β-Si3N4 particles are thought to be nucleation sites for silicon in multicrystalline silicon (mc-Si) ingots for PV applications. The orientation relationship (OR) between Si and β-Si3N4 has been investigated by transmission ... -
Orientation relationships of phase transformation in α-Al12Mn3Si pseudomorphs after plate-like Al6Mn precipitate in an AA3004 Al-Mn based alloy
(Journal article; Peer reviewed, 2017)The phase transformation in the plate-like precipitates of Al6Mn in an AA3004 Al-Mn based alloy, which was prepared by a chemical extraction technique, was investigated using transmission electron microscopy. The boiling-phenol ... -
Orientational dependence of the van der Waals interactions for finite-sized particles
(Journal article, 2018)Dispersion forces, especially van der Waals forces as interactions between neutral and polarizable particles act at small distances between two objects. Their theoretical origin lies in the electromagnetic interaction ... -
Orientational mapping of minerals in Pierre shale using X-ray diffraction tensor tomography
(Peer reviewed; Journal article, 2021)Shales have a complex mineralogy with structural features spanning several length scales, making them notoriously difficult to fully understand. Conventional attenuation-based X-ray computed tomography (CT) measures density ... -
Orienteering from Cradle to Grave—How a Sport Could Offer Lifelong Participation
(Peer reviewed; Journal article, 2021)Background: The aim of this present study is to explore what makes orienteering meaningful and rewarding to former elite athletes’ years or even decades after ending their elite careers. Methods: Applying a qualitative ... -
Origin and role of the cerebrospinal fluid bidirectional flow in the central canal
(Peer reviewed; Journal article, 2020)Circulation of the cerebrospinal fluid (CSF) contributes to body axis formation and brain development. Here, we investigated the unexplained origins of the CSF flow bidirectionality in the central canal of the spinal cord ... -
Origin and spatial distribution of metals in moss samples in Albania: A hotspot of heavy metal contamination in Europe
(Journal article; Peer reviewed, 2018)This study presents the spatial distribution of 37 elements in 48 moss samples collected over the whole territory of Albania and provides information on sources and factors controlling the concentrations of elements in the ... -
Origin of anhydrite rocks in the Tromsø Basin, and the evolution of the Tromsø Basin in the light of salt tectonics
(Master thesis, 2016)The Southwestern Barents Sea Shelf is estimated to contain 260 300 billion m3 of gas reserves, of which a significant amount have been proven to be associated with salt structures in the Nordkapp Basin. Salt tectonics ... -
Origin of anomalously stabilizing ice layers on methane gas hydrates near rock surface
(Peer reviewed; Journal article, 2023)Gas hydrates (GHs) in water close to freezing temperatures can be stabilised via the formation of ice layers. In a recent work [Boström et al., Astron. Astrophys., A54, 650, 2021], it was found that a surface region with ... -
Origin of Chemisorption Energy Scaling Relations over Perovskite Surfaces
(Journal article; Peer reviewed, 2019)Rationally tailored perovskites ABO3 are promising substitutes for expensive noble-metal catalysts in heterogeneous catalysis. In this contribution, the BEEF-vdW + U method has been used to examine the adsorption of H, C, ... -
Origin of ferroelectric polarization in tetragonal tungsten-bronze-type oxides
(Journal article; Peer reviewed, 2016)The origin of ferroelectric polarization in tetragonal tungsten-bronze- (TTB-) type oxide strontium barium niobate (SBN) is investigated using first-principles density functional calculations. We study in particular the ... -
Origin of Leakage Currents and Nanowire-to-Nanowire Inhomogeneity in Radial p-i-n Junction GaAs Nanowire Array Solar Cells on Si
(Journal article; Peer reviewed, 2023)To realize the promising potential of radial junction nanowire (NW) array-based solar cells, it is crucial to get physical insight into how the overall photoconversion efficiency (PCE) is impacted by the hole mask properties, ... -
Origin of potassium promotion effects on CuCl2/gamma-Al2O3 catalyzed ethylene oxychlorination
(Peer reviewed; Journal article, 2020)Potassium promoters are widely used in industrial catalysts of ethylene oxychlorination to achieve optimum performance. However, the origin of the promoter effect is not fully understood. Herein, we investigated the potassium ... -
