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 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 ... -
Mass cytometry analysis of the tumour-immune landscape: The role of Axl receptor kinase
(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
(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 ... -
Mechanistic Modelling of Radial Polymer Flow in Porous Media
(Doctoral thesis, 2020-09-29)Polymer flooding is one of the most successful chemically enhanced oil recovery (EOR) methods, and has primarily been implemented to accelerate oil production by sweep improvement. However, research from the last couple ... -
A method for automated de novo design of functional transition-metal compounds
(Doctoral thesis, 2015-10-05)Systematic application of automated design methods in transition metal and organometallic chemistry is hampered by the limitations of computational tools traditionally developed according to organic chemistry formalisms. ... -
Methyl 5-iodo-2-methoxybenzoate
(Peer reviewed; Journal article, 2014-04)In the title compound, C9H9IO3, the molecules are close to planar [maximum deviation from benzene ring plane = 0.229 (5) Å for the methyl carboxylate C atom] with the methyl groups oriented away from each other. In the ... -
