The unique hybrid precipitate in a peak-aged Al-Cu-Mg-Ag alloy
(Peer reviewed; Journal article, 2021)The prevalent hardening phase forming in an Al-Cu-Mg-Ag alloy after peak-aging at 150 and 190 °C has been investigated using transmission electron microscopy methods. The precipitate atomic structure was determined. It is ... -
Unique photosynthetic electron transport tuning and excitation distribution in heterokont algae
(Journal article; Peer reviewed, 2019)Heterokont algae are significant contributors to marine primary productivity. These algae have a photosynthetic machinery that shares many common features with that of Viridiplantae (green algae and land plants). Here we ... -
Universal absence of Walker breakdown and linear current–velocity relation via spin–orbit torques in coupled and single domain wall motion
(Journal article, 2017)We consider theoretically domain wall motion driven by spin-orbit and spin Hall torques. We find that it is possible to achieve universal absence of Walker breakdown for all spin-orbit torques using experimentally relevant ... -
Universal Scaling Theory of the Boundary Geometric Tensor in Disordered Metals
(Peer reviewed; Journal article, 2019)We investigate the finite-size scaling of the boundary quantum geometric tensor (QGT) numerically close to the Anderson localization transition in the presence of small external magnetic fields. The QGT exhibits universal ... -
Unraveling the Nanoscale Dynamics of Ice friction Molecular Dynamics Simulations investigating the Structural Evolution of Ice-Solid Interfaces
(Master thesis, 2023)Friksjon er et sentralt fenomen i hverdagen vår, men de fleste overser nok hvor essensielt det faktisk er. I dagliglivet omgir vi oss med både smart og tradisjonell teknologi hvor friksjonsinteraksjoner er avgjørende for ... -
Unveiling the Nature of Galactic TeV Sources with IceCube Results
(Peer reviewed; Journal article, 2023)IceCube collaboration reported the first high-significance observation of the neutrino emission from the Galactic disk. The observed signal can be due to diffuse emission produced by cosmic rays interacting with interstellar ... -
Uptake of circulating extracellular vesicles from rectal cancer patients and differential responses by human monocyte cultures
(Journal article; Peer reviewed, 2021)Extracellular vesicles (EVs) released by tumor cells can directly or indirectly modulate the phenotype and function of the immune cells of the microenvironment locally or at distant sites. The uptake of circulating EVs and ... -
Use of 4x4 transfer matrix method in the study of surface magnon polaritons via simulated attenuated total reflection measurements on the antiferromagnetic semiconductor MnF2
(Peer reviewed; Journal article, 2022)The surface magnon polaritons (SMPs) present in thin film antiferromagnet semiconductors can be extremely confined, having most of their energy distributed within the magnetic medium. For extremely thin films these SMPs ... -
Using atomic force microscopy and second harmonic generation to investigate the effects of ultrasound and microbubbles on the extracellular matrix in 4T1 breast tumors
(Master thesis, 2022)For å forbedre leveringen av kreftmedisin til svulster har man sett at bruken av mikrobobler kombinert med ultralyd kan ha en positiv effekt. Denne typen behandling har vist seg å kunne øke distansen legemiddelet beveger ... -
Using Background OH Airglow from astronomical Observations for atmospheric Research: A Proof of Concept
(Master thesis, 2015)The physics of the hydroxyl (OH) layer located in the Mesosphere and Lower Thermosphere (MLT) has become a focus of interest, as more and more climate models extend into this region. This is shown by the IPCC's last two ... -
Using Convolutional Neural Networks for the Helicity Classification of Magnetic Fields

Using Photon Entanglement as a Fundamental Resource in Experimental Physics
(Master thesis, 2019)I denne masteroppgaven beskriver jeg to ulike eksperimenter relatert til bruken av sammenfiltrede fotonpar for metrologi og kvantenøkkeldistribusjon. Innenfor metrologi undersøkes et oppsett for å synkronisere klokker ... -
Using STEM-DPC with a Conventional ADF Detector to Explore FIB Patterned Artificial Spin Ice Structures in Permalloy
(Master thesis, 2023)Vi befinner oss midt i en bemerkelsesverdig teknologisk revolusjon, der utviklingen innenfor områder som kunstig intelligens, robotikk og informasjonsteknologi er enorm. Som følge av dette er det et stort behov for mer ... -
Utregning av det elektromagnetiske feltet i Monte Carlo transport simulering
(Master thesis, 2017)Løsning av poissons ligning under monte carlo simulering av en CdHgTe fotoskred-diode. Vi har tatt i bruk ikke-uniform mesh med adaptivt grid og gjort noen elementære simuleringer av CMT dioden. -
