A unified approach for the calculation of in-plane dielectric constant of films with interdigitated electrodes
(Peer reviewed; Journal article, 2020)Interdigitated electrodes (IDEs) on dielectric films is an important electrode design in electrical components such as transducers and sensors. Further development and use of IDEs for characterization of the in-plane ... -
Unifying Transport Phenomena and Thermodynamic Equilibrium Models: A theoretical study of current and novel equilibrium based models in transport phenomena
(Doctoral theses at NTNU;2023:87, Doctoral thesis, 2023)Transport phenomena are based on the conservation of mass, momentum, and energy, and provide equations that give insight into the motion of fluids, the driving force behind this motion, and the dissipation of such driving ... -
Unimolecular Decomposition Reactions of Picric Acid and its Methylated Derivatives – A DFT Study
(Master thesis, 2021)Til tross for at eksplosiver og andre energetiske materialer har blitt benyttet og studert i over hundre år, er forståelsen av deres følsomhet fremdeles svært begrenset. Gode modeller som forutsier følsomhet, kan gjøre ... -
Unimolecular Decomposition Reactions of Picric Acid and its Methylated Derivatives — A DFT Study
(Peer reviewed; Journal article, 2022)To handle energetic materials safely, it is important to have knowledge about their sensitivity. Density functional theory (DFT) has proven a valuable tool in the study of energetic materials, and in the current work, DFT ... -
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 ... -
Uniqueness of Dissipative Solutions for the Hunter--Saxton Equation
(Master thesis, 2024)Denne oppgaven utforsker unikheten av globale, dissipative løsninger av den symmetrisk integrerte Hunter–Saxton-ligningen med initialdata u0 ∈ E2 med derivert u0,x nesten overalt begrenset ovenfra, hvor E2 er mengden av ... -
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 ... -
Universality of Torpor Expression in Bats
(Peer reviewed; Journal article, 2022)Although heterothermy is employed by species at a global level within the order of Chiroptera (bats), the possibility of torpor being expressed in bat species inhabiting warmer climate zones has been explored only in the ... -
Unleash electron transfer in C-H functionalization by mesoporous carbon-supported palladium interstitial catalysts
(Peer reviewed; Journal article, 2021)The functionalization of otherwise unreactive C–H bonds adds a new dimension to synthetic chemistry, yielding useful molecules for a range of applications. Arylation has emerged as an increasingly viable strategy for ... -
Unlocking the genomic potential of aerobes and phototrophs for the production of nutritious and palatable microbial food without arable land or fossil fuels
