Restitusjon av akvatiske økosystemer utsatt for sur nedbør
(Bachelor thesis, 2023)Sur nedbør var et stort problem i Norge på slutten av forrige århundre. Sur nedbør blir dannet ved at utslipp av gasser reagerer med vann i atmosfæren. Dette påvirket de akvatiske økosystemene i stor grad, og førte blant ... -
Reversible heat effects of lithium metal- and porous lithium iron phosphate electrodes
(Peer reviewed; Journal article, 2023)We report Peltier heats and reaction entropy of cells with lithium metal- and near fully lithiated lithium iron phosphate (LFP) electrodes. The Peltier heats were measured through the Seebeck coefficient of thermogalvanic ... -
Review - Reversible heat effects in cells relevant for lithium-ion batteries
(Peer reviewed; Journal article, 2021)We review measurements of reversible heat effects in lithium-ion batteries, i.e. entropy changes and Seebeck coefficients of cells with relevant electrodes. We show how to compute the Peltier heat of battery electrodes ... -
Roads with underlying tar asphalt - spreading, bioavailability and toxicity of their polycyclic aromatic hydrocarbons
(Peer reviewed; Journal article, 2021)Some of the older Swedish roads contain road tar underneath a surface layer of bituminous asphalt. This road tar, also known as tar asphalt, contains large amounts of polycyclic aromatic hydrocarbons (PAHs). There is concern ... -
The Role of Chloride ion in the Silicate Condensation Reaction from ab Initio Molecular Dynamics Simulations
(Journal article; Peer reviewed, 2023)The comprehension of silicate oligomer formation during the initial stage of zeolite synthesis is of significant importance. In this study, we investigated the effect of chloride ions (Cl–) on silicate oligomerization using ... -
The role of crystallinity and particle morphology on the sorption of dibutyl phthalate on polyethylene microplastics: Implications for the behavior of phthalate plastic additives
(Peer reviewed; Journal article, 2021)The sorption behavior of phthalate additives in plastic and microplastic litter is an important process controlling the exposure, net health risk and ecotoxicity of these co-occurring pollutants. Plastic crystallinity and ... -
The role of pressure and defects in the wurtzite to rock salt transition in cadmium selenide
(Peer reviewed; Journal article, 2022)Using molecular dynamics and path sampling techniques we investigated the effect of pressure and defects in the wurtzite to rock salt transition in cadmium selenide (CdSe). In the pressure range 2–10 GPa, rate constants ... -
Salinity acclimation strategies for nitrifying bioreactors in recirculating aquaculture systems
(Doctoral theses at NTNU;2021:33, Doctoral thesis, 2021)The demand for seafood is rising like never before, and unsustainable fishing has depleted the oceans. Recirculating aquaculture systems (RAS) can present a sustainable solution by producing seafood in land-based systems ... -
Salt efflorescence in historic wooden buildings
(Peer reviewed; Journal article, 2016)Efflorescence and subflorescence are frequent phenomena occurring in buildings of porous inorganic materials such as bricks, stone, and concrete. Since the above phenomena have detrimental effects, they were the subject ... -
A salty start: Brackish water start-up as a microbial management strategy for nitrifying bioreactors with variable salinity
(Peer reviewed; Journal article, 2020)Nitrifying biofilms developed in brackish water are reported to be more robust to salinity changes than freshwater biofilms. This makes them a promising strategy for water treatment systems with variable salinity, such as ... -
Samanlikning av ferroelektriske eigenskapar i PbZrxTi1-xO3, BaTiO3 og [N(CH3)4][FeBrCl3]
(Bachelor thesis, 2023)Denne teksten skal sjå på fordelane og ulempene ved å bruke supermolekylære ferroelektriske materialer som erstatning for intermolekylære ferroelektriske materialer, som bly zirkonat titanat (PZT) og barium titanat (BTO). ... -

Sammenligning av metoder for syntese av d-threo-metylfenidat hydroklorid
(Bachelor thesis, 2023)Etterspørselen etter ADHD-medisin er stadig økende, og det er derfor et behov for å effektivt produsere virkestoffet d-threo-metylfenidat hydroklorid. I denne oppgaven blir tre synteser av d-threo-metylfenidat hydroklorid ... -
SAPO-34 with Copper: Investigation of hierarchical pore characteristics and interactions with copper for catalytic applications
(Master thesis, 2014)Hierarchical SAPO-34 was produced using the dry gel conversion method, where an amorphous, mesoporous silicoaluminophosphate was subjected to steam treatment with the presence of organic template. This resulted in a ... -
Saturation of radiative heat transfer due to many-body thermalization
(Peer reviewed; Journal article, 2020)Radiative heat transfer between two bodies saturates at very short separation distances due to the nonlocal optical response of the materials. In this work, we show that the presence of radiative interactions with a third ... -
