Thermal gradient driven domain wall dynamics
(Journal article; Peer reviewed, 2019)The issue of whether a thermal gradient acts like a magnetic field or an electric current in the domain wall (DW) dynamics is investigated. Broadly speaking, magnetization control knobs can be classified as energy-driving ... -
Thermal Gradients with Sintered Solid State Electrolytes in Lithium-Ion Batteries
(Journal article; Peer reviewed, 2020)The electrolyte is one of the three essential constituents of a Lithium-Ion battery (LiB) inaddition to the anode and cathode. During increasingly high power and high current charging anddischarging, the requirement for ... -
Thermal Insulation Materials in Aluminum Electrolysis Cells
(Doctoral theses at NTNU;2020:112, Doctoral thesis, 2020)Aluminum is produced by an energy intensive process known as the Hall-Héroult process, which has been developed extensively since it was first invented in 1886. Recent trends in the aluminum industry has been to strive for ... -
Thermal modeling of the respiratory turbinates in arctic and subtropical seals
(Peer reviewed; Journal article, 2023)Mammals possess complex structures in their nasal cavities known as respiratory turbinate bones, which help the animal to conserve body heat and water during respiratory gas exchange. We considered the function of the ... -
Thermal oxidation of polyolefins by mild pro-oxidant additives based on iron carboxylates and lipophilic amines: Degradability in the absence of light and effect on the adhesion to paperboard
(Journal article; Peer reviewed, 2015)Marine and inland pollution by non-degradable plastic bags and other plastic articles is a topic of great concern. Natural degradation processes based on oxidation of plastic pollutants could possibly contribute to limit ... -
Thermal performance in zebrafish (Danio rerio) - Thermal acclimation capacity in wild and domesticated zebrafish
(Master thesis, 2018)In times of imminent threat of climate change, clear evidence of which physiological mechanisms are limiting thermal performance remains scarce. This thesis involved measuring different performances, over a wide range of ... -
Thermal physiology and activity in relation to reproductive status and sex in a free-ranging semelparous marsupial
(Journal article; Peer reviewed, 2019)In a changing climate, southern hemisphere mammals are predicted to face rising temperatures and aridity, resulting in food and water shortages, which may further challenge already constrained energetic demands. Especially ... -
Thermal preference in both temperature acclimated and thermal tolerance-selected zebrafish (Danio rerio)
(Master thesis, 2021)Det forventes at klimaendringer vil føre til en økning i plutselige varmeøkninger noe som gjør det viktig å ha evnen til å tilpasse seg det nye miljøet. Ektoterme arter sine fysiologiske funksjoner blir svært påvirket av ... -
