A retrospective investigation of feather corticosterone in a highly contaminated white-tailed eagle (Haliaeetus albicilla) population
(Peer reviewed; Journal article, 2023)Exposure to persistent organic pollutants (POPs), such as organochlorines (OCs) and polybrominated diphenyl ethers (PBDEs), is associated with adverse health effects in wildlife. Many POPs have been banned and consequently ... -
Return-mapping algorithm for rate-independent crystal yield surface
(Master thesis, 2020)Hovedmålet med dette arbeidet var å utvikle en stabil og hurtig numerisk algoritme for krystallplastisitet med vilkårlige slip systemer og krystallelastisitet. Ved å bruke en regularisert flyteflate blir metodene for ... -
Reusable crucible materials and coatings for photovoltaic silicon applications
(Doctoral theses at NTNU;2021:419, Doctoral thesis, 2021)Currently, more than 90% of commercial solar cells are made from crystalline silicon. The crystalline silicon materials are classified into two types: monocrystalline and multi-crystalline silicon. Multi-crystalline silicon ... -
Revalorization of agar from red seaweed as microbial feedstock for Corynebacterium glutamicum
(Master thesis, 2023)I dag er mikrobiell fermentering hovedsakelig basert på bruk av sukker som karbonkilde, hvilket kan virke begrensende når det kommer til bærekraft og konkurrerende bruk av sukker som kilde for menneske- og dyrenæring. ... -
Revealing abnormal {11-21} twins in commercial purity Ti subjected to split Hopkinson pressure bar
(Journal article, 2019)The deformation behavior of Ti alloys during conventional deformation, such as rolling and compression,have been extensively investigated, while it is less understood during high strain rate deformation. In thepresent work, ... -
Revealing internal flow behaviour in arc welding and additive manufacturing of metals
(Journal article; Peer reviewed, 2018)Internal flow behaviour during melt-pool-based metal manufacturing remains unclear and hinders progression to process optimisation. In this contribution, we present direct time-resolved imaging of melt pool flow dynamics ... -
Revealing mechanisms of activated carbon capacity fade in lithium-ion capacitors
(Peer reviewed; Journal article, 2023)The capacity fade mechanism of activated carbon (AC) electrode in Li-ion electrolyte was studied via electrochemical impedance spectroscopy (EIS) and post-mortem electrode characterizations at different stages of electrochemical ... -
Revealing Missing Pieces of the Puzzle: The Possible Function of Candidate Genes in the Cell Wall Integrity Maintenance mechanism in Arabidopsis thaliana
(Master thesis, 2018)As sessile organisms, plants depend on mechanisms to sense and respond to stressful conditions such as biotic and abiotic factors. A complex mechanism referred to as the cell wall integrity maintenance (CWI) mechanism, has ... -
Revealing slip-induced extension twinning behaviors dominated by micro deformation in a magnesium alloy
(Peer reviewed; Journal article, 2020)In this study, an in situ SEM/EBSD study on slip-induced extension twinning (S→T) behaviors of a Mg–Y alloy was conducted. It shows that the S→T process cannot be well explained using the classical geometrical compatibility ... -
Revealing the factors influencing grain boundary segregation of P, As in Si: Insights from first-principles
(Journal article; Peer reviewed, 2019)Phosphorous (P) and arsenic (As) segregation at grain boundaries (GBs) usually deteriorate the electrical performance of n-type doped Si-wafers. In order to probe the factors influencing P and As segregation behaviors along ... -
