Advancing Methods for Sampling and Analysis of Microplastics in the Marine Environment
(Doctoral theses at NTNU;2024:24, Doctoral thesis, 2024)Plastic pollution is one of many growing anthropogenic stressors in the marine environment, and its proliferation and effects are not fully understood. Research reporting abundance of plastic debris in the environment is ... -
Advancing Spintronics through Ellipsometric Characterisation of Surface Polaritons
(Doctoral theses at NTNU;2024:133, Doctoral thesis, 2024)Spintronics is a subtopic of magnonics in which the spin of the electron is used to store and process information. Magnonics is the magnetic analogue of the recently popularised field of plasmonics, which deals with the ... -
Aerogels; a new class of materials for catalytic purposes
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:212, Doctoral thesis, 2013)Silica aerogels containing copper(II) cations were prepared by adding the metal precursor during the sol-gel stage. The gel surfaces were made hydrophobic by applying the ambient-pressure-drying (APD) method, and various ... -
Aeronomy of hydroxyl airglow variability by means of high-resolution telescope observations and gravity wave simulations
(Doctoral theses at NTNU;2019:202, Doctoral thesis, 2019)Are there waves on the fjord right now? “Easy to find out”, you might think. Just go down to the water and have a look. Now imagine that you are in Oppdal, about 90 kilometres away, trying to see the waves on the fjord in ... -
