Leaflet Tensions Control the Spatio-Temporal Remodeling of Lipid Bilayers and Nanovesicles
(Journal article; Peer reviewed, 2023)Biological and biomimetic membranes are based on lipid bilayers, which consist of two monolayers or leaflets. To avoid bilayer edges, which form when the hydrophobic core of such a bilayer is exposed to the surrounding ... -
Lineshape Models in Inner-shell Photoelectron Spectra of Free Molecules and Clusters
(Doctoral thesis, 2006-09-22)Investigating the nature of molecules and clusters is of paramount importance for our understanding of the composition and the properties of matter. X-ray photoelectron spectroscopy is one of the most powerful techniques ... -
Lipider og fettsyrekomposisjon i isbjørn (Ursus maritimus) - Stratifisering og laktering
(Master thesis, 2008-06-18)På Kjemisk Institutt ved Universitetet i Bergen blir det forsket på marine fettsyrer og jeg har vært med på å analysere fettvev fra levende isbjørn (Ursus maritimus). Materialet mottok jeg fra Norsk Polarinstitutt, i form ... -
Lokalisering av (R)-artikain i et lipidbilag
(Master thesis, 2020-12-15)Hensikten med denne oppgaven var å undersøke interaksjonen mellom (R)-artikain og lipidbilag av POPC ved bruk av fast-fase NMR-spektroskopi. Artikain hydroklorid brukes som et lokalbedøvelsesmiddel innen tannbehandling, ... -
Loss and Reformation of Ruthenium Alkylidene: Connecting Olefin Metathesis, Catalyst Deactivation, Regeneration, and Isomerization
(Peer reviewed; Journal article, 2017)Ruthenium-based olefin metathesis catalysts are used in laboratory-scale organic synthesis across chemistry, largely thanks to their ease of handling and functional group tolerance. In spite of this robustness, these ... -
Low Molecular Weight Hydrogel for Wound Healing
(Journal article; Peer reviewed, 2023)Octadecylazanediyl dipropionic acid (C18ADPA) is a zwitterionic amphiphile with a dendritic headgroup. C18ADPA self-assembles to lamellar networks, which encompasses water and forms a low-molecular-weight hydrogel (LMWG). ... -
Low Salinity Surfactant Flooding in Sandstone Cores
(Doctoral thesis, 2018-01-26)A new generation enhanced oil recovery (EOR) methods comes from combining techniques to make the overall process more efficient than either of the processes alone. These combined methods are often called hybrid EOR methods, ... -
LTX-315: a first-in-class oncolytic peptide that reprograms the tumor microenvironment
(Peer reviewed; Journal article, 2017)The oncolytic peptide LTX-315, which has been de novo designed based on structure–activity relationship studies of host defense peptides, has the ability to kill human cancer cells and induce specific anticancer immune ... -
