Effect of Reaction Conditions on Catalytic and Noncatalytic Lignin Solvolysis in Water Media Investigated for a 5 L Reactor
(ACS, 2019)The high content of oxygen in the lignin polymer and the prevalence of phenolic functional groups make the conversion of lignin to fuels and value-added products with well-defined chemical properties challenging. The ...Journal article -
Phenylethylene glycol-derived LpxC inhibitors with diverse Zn2+-binding groups
(Elsevier, 2019)The Zn2+-dependent bacterial deacetylase LpxC is a promising target for the development of novel antibiotics. Most of the known LpxC inhibitors carry a hydroxamate moiety as Zn2+-binding group. However, hydroxamic acids ...Journal article -
Natural products against acute respiratory infections: Strategies and lessons learned
(Elsevier, 2020)Ethnopharmacological relevance: A wide variety of traditional herbal remedies have been used throughout history for the treatment of symptoms related to acute respiratory infections (ARIs). Aim of the review: The ...Journal article -
C–H-Bond Activation and Isoprene Polymerization Studies Applying Pentamethylcyclopentadienyl-Supported Rare-Earth-Metal Bis(Tetramethylaluminate) and Dimethyl Complexes
(MDPI, 2019)As previously shown for lutetium and yttrium, 1,2,3,4,5-pentamethylcyclopentadienyl (C5Me5 = Cp*)-bearing rare-earth metal dimethyl half-sandwich complexes [Cp*LnMe2]3 are now also accessible for holmium, dysprosium, and ...Journal article -
Multiscale investigation of CO2 hydrate self-sealing potential for carbon geo-sequestration
(Elsevier, 2020)Storage of liquid CO2 in shallow geological formations is a recently proposed concept that can facilitate increased storage capacity and improved mobility control. If stored below the gas hydrate stability zone (GHSZ), ...Journal article -
Mechanistic Insight for Improved Catalytic Conversion of Fatty Acids to Linear α-Olefins : A Density Functional Theory Study
(The University of Bergen, 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 ...Doctoral thesis -
GLORY: Generator of the structures of likely cytochrome P450 metabolites based on predicted sites of metabolism
(Frontiers, 2019-06-12)Computational prediction of xenobiotic metabolism can provide valuable information to guide the development of drugs, cosmetics, agrochemicals, and other chemical entities. We have previously developed FAME 2, an effective ...Journal article -
