Lineshape Models in Inner-shell Photoelectron Spectra of Free Molecules and Clusters

Abu-samha, Mahmoud (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

Berntsen, Jannicke Alling (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

Lande, Anna Vår (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

Engel, Julien; Smit, Wietse; Foscato, Marco; Occhipinti, Giovanni; Törnroos, Karl Wilhelm; Jensen, Vidar Remi (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 Salinity Surfactant Flooding in Sandstone Cores

Johannessen, Annette Meland (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

Sveinbjørnsson, Baldur; Camilio, Ketil Andre; Haug, Bengt Erik; Rekdal, Øystein (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 ...

Mass cytometry analysis of the tumour-immune landscape: The role of Axl receptor kinase

Grøndal, Sturla Magnus (Master thesis, 2018-12-08)

Cancer is one of the leading causes of death in Norway (2016) and worldwide. Despite the advent of new immunotherapies, malignant cancer demonstrates an intrinsic plasticity and is able to evade, adapt and suppress the ...

Mechanistic Insight for Improved Catalytic Conversion of Fatty Acids to Linear α-Olefins : A Density Functional Theory Study

Eliasson, Sondre Hilmar Hopen (Doctoral thesis, 2020-02-14)

One of the greatest challenges in our time is the replacement of fossil fuels with more sustainable alternatives for energy and chemical production. Arguably one of the most important classes of petrochemical intermediates ...
