Small Size Effects in Open and Closed Systems: What Can We Learn from Ideal Gases about Systems with Interacting Particles?
(Peer reviewed; Journal article, 2021)Small systems have higher surface area-to-volume ratios than macroscopic systems. The thermodynamics of small systems therefore deviates from the description of classical thermodynamics. One consequence of this is that ... -
Soil Metabolome Impacts the Formation of the Eco-corona and Adsorption Processes on Microplastic Surfaces
(Peer reviewed; Journal article, 2023)The eco-corona on microplastics refers to the initial layer of biomolecular compounds adsorbed onto the surface after environmental exposure. The formation and composition of the eco-corona in soils have attracted relatively ... -
Soil-water influences on trace elements and organic matter in Arctic
(Master thesis, 2019)Abstract In this study, the impact of pH on leaching of elements from soils was tested. Samples were taken from Bayelva / Stuphalle, Svalbard in August 2018. Overall, the impact of three pH levels, 2, 7 and 10 was ... -
Solid state phase transition materials for thermal energy storage - A review on the potential and limitations of solid-solid phase change materials for latent thermal energy storage
(Bachelor thesis, 2023)Termisk energilagring spiller en viktig rolle i utviklingen av en mer bærekraftig fremtid, og fastfase faseendringsmaterialer for latent termisk energilagring har et stort potensial i denne utviklingen. Latent varmelagring ... -
Solvent Effects on Optical Rotation: On the Balance between Hydrogen Bonding and Shifts in Dihedral Angles
(Journal article; Peer reviewed, 2017)Optical rotations of several conformers of four fluorinated molecules containing the 1-naphthalene or 4-(benzyloxy)phenyl group at the stereocenter have been calculated both in the gas phase and in an aqueous environment. ... -
Solvent-Mediated Forces between Ellipsoidal Nanoparticles Adsorbed at Liquid–Vapor Interfaces
(Peer reviewed; Journal article, 2020)Classical capillary theory predicts that a non-neutrally wetting ellipsoidal particle adsorbed at a liquid–vapor interface will deform the interface. The deformation gives rise to anisotropic capillary forces of a quadrupolar ... -
Solvents for Membrane-Based Post-Combustion CO2 Capture for Potential Application in the Marine Environment
(Peer reviewed; Journal article, 2022)Carbon capture on-board ships represents a powerful technological measure in order for the shipping industry to meet the very stringent GHG emission reduction requirements. Operation within the ship environment introduces ... -
Sorption and Mobility of Charged Organic Compounds: How to Confront and Overcome Limitations in Their Assessment
(Peer reviewed; Journal article, 2022)Permanently charged and ionizable organic compounds (IOC) are a large and diverse group of compounds belonging to many contaminant classes, including pharmaceuticals, pesticides, industrial chemicals, and natural toxins. ... -
Spatial patterns and temporal trends of heavy metal concentrations in moss and surface soil specimens collected in Norway between 1990 and 2010
(Journal article; Peer reviewed, 2014-10-11)Background: The aim of this investigation was to inquire whether the spatial patterns and temporal trends of heavy metal concentrations in moss and soil specimen monitored in two spatial dense networks covering Norway are ... -
Spatial Variability of Black Carbon Deposited on Snow in Ny-Ålesund, Svalbard: Impact of Anthropogenic Activities
(Master thesis, 2019)Black Carbon (BC) is a carbonaceous particle emitted globally during the incomplete combustion of biomass and carbon-based fuels. It is considered one of the strongest climate-forcing agents due to its high capacity to ... -
Speciering av atmosfærisk kvikksølv på Zeppelin, Ny-Ålesund - Sammenhenger mellom kvikksølv, meteorologiske forhold, aerosolstørrelsesfordelinger og UVB-stråling
(Master thesis, 2016)Speciering av atmosfærisk kvikksølv ble utført ved Zeppelinobservatoriet i Ny-Ålesund (79 °N), Svalbard, for perioden 31.03.2007 til 31.12.2012. Syklusen til kvikksølv i Arktis er kompleks, og det er flere faktorer som ... -
Spin adapted implementation of EOM-CCSD for triplet excited states: Probing intersystem crossings of acetylacetone at the carbon and oxygen K-edges
(Journal article; Peer reviewed, 2019)We present an equation of motion coupled cluster singles and doubles approach for computing transient absorption spectra from a triplet excited state. The implementation determines the left and right excitation vectors by ... -
Spin-adapted Open-shell Coupled Cluster Theory
(Master thesis, 2022)Åpenskall-molekyler er av stor interesse ettersom de gjennomgående opptrer i kjemi, særlig når det kommer til reaksjonsmekanismer hvor bindinger dannes og brytes. En nøyaktig beskrivelse av slike molekyler er derfor viktig ... -
Spontaneous Formation of Nanogap Electrodes by Self‐Peeling Adhesion Lithography
(Journal article; Peer reviewed, 2019)Adhesion lithography (“a‐lith”) is a simple method for forming nanoscale gaps between dissimilar metals. In its usual form, a metal is patterned on a substrate, and conformally coated with an alkyl‐functionalized self‐assembled ... -
