IRON AS A DRIVING FORCE OF LIFE: INVESTIGATING EFFECTS OF IRON SOURCE ON PHYSIOLOGICAL FACTORS AND BIOTIC IRON RELATIONSHIPS IN SYNECHOCOCCUS SP. PCC 7002
(Doctoral theses at NTNU;2021:347, Doctoral thesis, 2021)Iron is one of the most abundant elements in the Earth’s crust, and yet it is a limiting factor for primary production in large parts of the world’s oceans. This is due to the low solubility of iron throughout the water ... -
Excavated vs novel in situ soil washing as a remediation strategy for sandy soils impacted with per- and polyfluoroalkyl substances from aqueous film forming foams
(Peer reviewed; Journal article, 2021)In situ soil washing at the field scale has not yet been investigated as a remediation strategy for soils impacted by per- and polyfluoroalkyl substances (PFAS). This remediation strategy is a promising low-cost alternative ... -
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 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 ... -
Weathering Plastics as a Planetary Boundary Threat: Exposure, Fate, and Hazards
(Peer reviewed; Journal article, 2021)We described in 2017 how weathering plastic litter in the marine environment fulfils two of three criteria to impose a planetary boundary threat related to “chemical pollution and the release of novel entities”: (1) ... -
Trace elements in whole blood in the general population in Trøndelag County, Norway: The HUNT3 Survey
(Journal article; Peer reviewed, 2021)Background: Biomonitoring of a cohort within a large health survey can provide reliable information on trace element status. The main aims of this study were 1) to determine the concentrations of 28 trace elements in whole ... -
Controlled patterning of metallic nanogaps and nanogap arrays via adhesion lithography
(Doctoral theses at NTNU;2021:181, Doctoral thesis, 2021)Existing nanofabrication methods typically rely on techniques such as optical lithography, electron-beam lithography or focused ion beam milling that enable high fidelity patterning but suffer from various limitations in ... -
In situ X-ray absorption spectroscopic studies of unsupported and supported CoRe during ammonia synthesis/ammonia decomposition
(Doctoral theses at NTNU;2021:407, Doctoral thesis, 2021)In situ X-ray absorption spectroscopy (XAS) studies are crucial for studying the local environment, oxidation state and speciation of transition metals during thermal pre-treatments and during working conditions of catalysts. ... -
Investigation of the occurrence and fate of multi-class organic micropollutants in the aquatic environment of the Norwegian Fjords
(Doctoral theses at NTNU;2021:372, Doctoral thesis, 2021)Summary in English This thesis describes efforts to develop rapid and robust methods for the analysis of seven classes of man-made organic pollutants of emerging concern and one method for the analysis of naturally occurring ... -
Adsorption of an Ideal Gas on a Small Spherical Adsorbent
(Peer reviewed; Journal article, 2021)The ideal gas model is an important and useful model in classical thermodynamics. This remains so for small systems. Molecules in a gas can be adsorbed on the surface of a sphere. Both the free gas molecules and the adsorbed ... -
Response Theory Based Methods for Electronic Transport
(Master thesis, 2021)Nanoelektronikk er er fagfelt som blir mer og mer relevant nå som elektronikk blir mindre og raskere, og med rask utvikling av teknologier som superledere og kvantedatamaskiner. Dette er et forskningsfelt der det har vært ... -
Effect of thiophene-based π-spacers on N-arylphenothiazine dyes for dye-sensitized solar cells
(Peer reviewed; Journal article, 2021)To study the effect of π-spacers on dye performance in DSSC, five novel phenothiazine dyes have been prepared where the number of successive thiophenes in the π-spacer was increased from zero to four. Additionally, a dye ... -
Product formation during discharge: a combined modelling and experimental study for Li–O2 cathodes in LiTFSI/DMSO and LiTFSI/TEGDME electrolytes
(Peer reviewed; Journal article, 2021)Li–air or Li–O2 batteries are a promising energy storage technology due to the potentially high energy density. However, significant challenges related to reversible charge/discharge of these cells need to be solved. The ... -
Quantifying Growth of Anisotropic Gold Nanoparticles and Understanding Growth Mechanisms
(Master thesis, 2021)Studiet av anisotrope gullnanopartikler (AuNPs) og deres vekst er et område av stor interesse på grunn av deres bemerkelsesverdige biokompatible og plasmoniske egenskaper. Disse egenskapene er sterkt avhengig av størrelse ... -
Nitrous oxide and hydrogen sulfide production in sludge from a recirculating aquaculture system (RAS)
