Limited mobility of dioxins near San Jacinto super fund site (waste pit) in the Houston Ship Channel, Texas due to strong sediment sorption
(Journal article; Peer reviewed, 2018)Sediments from a waste pit in Houston Ship Channel (HSC) were characterized using a number of molecular markers of natural organic matter fractions (e.g., pyrogenic carbon residues, PAHs, lignins), in addition to dioxins, ... -
Limiting current density as a selectivity factor in electrodialysis of multi-ionic mixtures
(Peer reviewed; Journal article, 2023)Electrodialysis is a promising technology to remove low concentrations of target ions from multi-ionic mixtures. While the synthesis of selective membranes is a prominent topic in research, few studies have been presented ... -
Lipase Catalysed Kinetic Resolution of Stiripentol
(Journal article; Peer reviewed, 2012)Kinetic resolution of rac-Stiripentol, catalysed by lipase A from Candida antarctica by esterification with vinyl butanoate was performed with an E-value of 24. This allowed isolation of (3S)-Stiripentol with an ee of 86 ... -
Lipase Catalyzed Synthesis of Enantiopure Precursors and Derivatives for β-Blockers Practolol, Pindolol and Carteolol
(Peer reviewed; Journal article, 2021)Sustainable methods for producing enantiopure drugs have been developed. Chlorohydrins as building blocks for several β-blockers have been synthesized in high enantiomeric purity by chemo-enzymatic methods. The yield of ... -
Lithium Extraction from Seawater Brine; Investigating a Frugal Method that could be easily Implemented in Developing Countries
(Master thesis, 2022)Behovet for litium (Li) øker i takt med det økende behovet for energilagring og blir nærmer seg p bli en forsyningsrisiko. I tillegg er effekten av utløpet av saltlaken fra ferskvannsindustrien et økende problem som kan ... -
Lithium ion-water clusters in strong electric fields: A quantum chemical study
(Journal article, 2015)We use density functional theory to investigate the impact that strong electric fields have on the structure and energetics of small lithium ion–water clusters, Li+·nH2O, with n = 4 or 6. We find that electric field strengths ... -
Lithium Recovery from Lithium-Ion EV Battery Waste: A Review of Current Methods and Challenges
(Bachelor thesis, 2023)Den voksende elbilsindustrien og den tilknyttede økningen i etterspørselen etter litium-ion-batterier (LIB) har resultert i en betydelig økning i batteriavfall. Nåværende resirkuleringskapasitet strever med å holde tritt ... -
LLZO as a Solid Electrolyte for Next Generation Batteries and their Potential Application in Electrical Vehicles
(Bachelor thesis, 2022)Faststoff-batterier anses å være oppfølgeren til konvensjonelle flytende elektrolyttbatterier, til og med forventet å overgå dem når det gjelder kapasitet, sikkerhet og levetid. Dessverre står denne teknologien overfor ... -
LNMO as a cathode material in Li-ion batteries: Reasons for capacity fade and measures taken to prevent it
(Bachelor thesis, 2023)Lithium nikkel manganoksid (LNMO) er en lovende kandidat som katodemateriale i Li-ion batterier (LIBs) på grunn av sin høye energitetthet. Batterier med LNMO som katodemateriale kan oppleve kapsitetstap over tid grunnet ... -
Local electric field factors by a combined charge-transfer and point-dipole interaction model
(Peer reviewed; Journal article, 2015)A force-field model for the local electric field as a linear response to a frequency-dependent external electric field is presented based on a combined charge-transfer and point–dipole interaction (CT-PDI) force-field model ... -

Local Field Factors and Dielectric Properties of Liquid Benzene
(Journal article; Peer reviewed, 2015)Local electric field factors are calculated for liquid benzene by combining molecular dynamic simulations with a subsequent force-field model based on a combined charge-transfer and point-dipole interaction model for the ... -
Local initiation conditions for water autoionization
(Journal article; Peer reviewed, 2018)The pH of liquid water is determined by the infrequent process in which water molecules split into short-lived hydroxide and hydronium ions. This reaction is difficult to probe experimentally and challenging to simulate. ... -
Local pollution sources in Ny-Ålesund. Follow-up study of booster impact area in Brøggerdalen, and new study of leaching pollutants from Kolhaugen
(Master thesis, 2023)Langtransportert forurenset luft til Arktis er et velldokumentert fenomen siden oppmerksomhet rundt persistente organiske miljøgifter økte på midten av 1900-tallet. Effekten av lokale, menneskeskapte forurensning i Arktisk ... -
Local thermodynamic description of isothermal single-phase flow in porous media
(Journal article; Peer reviewed, 2022)Darcy's law for porous media transport is given a new local thermodynamic basis in terms of the grand potential of confined fluids. The local effective pressure gradient is determined using non-equilibrium molecular dynamics, ... -
Long-range transport of pollutants to arctic areas by seabirds
(Master thesis, 2022)Målet i denne oppgaven er å identifisere miljøgifter i arktisk og se om disse har noen sammenheng med fugler i området. Det ble tatt jordprøver fra forskjellige lokasjoner i Kongsfjorden: Ossian Sars, Botnfjell, Storholmen, ... -
Lære ved å gjøre, lære ved å skrive?: - Om skriving og læring i eksperimentelt arbeid
(Master thesis, 2012)Denne oppgaven tar for seg noen av grunnene til at eksperimentelt arbeid i kjemi ikke har vært så læringseffektivt som man har trodd og ønsket. Den beskriver videre muligheter for å gjøre noe med problemene, både ved hjelp ... -
Mapping and study of contamination in sediment and water column in the area used for snow dumping in the Trondheimsfjord.
(Master thesis, 2016)I Trondheim dumpes det meste av overskuddssnøen fra byen og omegn direkte i fjorden fra kaier i havna. Snø tar opp forurensninger fra kilder i byen, og vil dermed være forurenset med stoffer som bla. tungmetaller og organiske ... -
