Peptidomimetic inhibitors targeting the membrane-binding site of the neutrophil proteinase 3
(Peer reviewed; Journal article, 2019)Proteinase 3 (PR3), together with other serine proteases, such as neutrophil elastase (NE) and cathepsin G (CG), regulates inflammatory and immune responses. However, in comparison with NE and CG, there is increasing ... -
A Permanently Porous Yttrium-Organic Framework Based on an Extended Tridentate Phosphine Containing Linker
(Journal article; Peer reviewed, 2017)The metal–organic framework [Y(tbpp)]·nDMF (1) was synthesized from yttrium(III) nitrate and the tritopic linker tris(4′-carboxy[1,1′-biphenyl]-4-yl)phosphine (H3tbpp). The distance between the coordinating atoms of the ... -
pH indikatorar: Inkorporering av pH-indikatorar i porøse silikastrukturar, som er syntetisert direkte på substrat, og hydrogelar med pH-avhengig ekspansjon.
(Master thesis, 2019-06-19)I dette prosjektet vart det sett på to alternative måtar å måle pH på med utgangspunkt i to ulike kolloidsystem; mesoporøse silikastrukturar og hydrogelar. Det vart laga mesoporøse silikastrukturar ved hjelp av stöberprosessen. ... -
Phase transfer catalysts shift the pathway to transmetalation in biphasic Suzuki-Miyaura cross-couplings
(Journal article; Peer reviewed, 2024)The Suzuki-Miyaura coupling is a widely used C-C bond forming reaction. Numerous mechanistic studies have enabled the use of low catalyst loadings and broad functional group tolerance. However, the dominant mode of ... -
Phenylethylene glycol-derived LpxC inhibitors with diverse Zn2+-binding groups
(Peer reviewed; Journal article, 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 ... -
Phosphine- and Indenylidene-Based Z-Selective Ruthenium Olefin Metathesis Catalysts and Catalyst Stability: Decomposition, Olefin Isomerization and Regeneration
(Doctoral thesis, 2019-11-22)This thesis describes the development and synthesis of phosphine-bearing first-generation Z-selective olefin metathesis catalysts that give 70–95% of the Z-isomer product in homocoupling of terminal alkenes such as ... -
Phosphine-Based Z‑Selective Ruthenium Olefin Metathesis Catalysts
(Peer reviewed; Journal article, 2016-05-18)Whereas a number of highly Z-selective ruthenium-based olefin metathesis catalysts bearing N-heterocyclic carbene ligands have been reported in recent years, Zselectivity has so far been difficult to achieve for phosphinebased ... -
Phospholipid Membrane Interactions of Model Ac-WL-X-LL-OH Peptides Investigated by Solid-State Nuclear Magnetic Resonance
(Journal article; Peer reviewed, 2024)The role of aromatic amino acids in peripheral protein membrane binding has been reported to involve cation–π interactions with choline lipids. In this study, we have investigated the interactions of the model pentapeptide ... -
Photocapacitor systems for generation and storage of electrical energy
(Master thesis, 2015-06-01)In this project, the combining of photovoltaic cells and supercapacitors into a single, photocapacitor system, was studied. A complete photocapacitor system of commercial components was put together, and characterized. The ... -
Photocatalytic TiO2/rGO/CuO Composite for Wastewater Treatment of Cr(VI) Under Visible Light
