(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The major virulence factor of enterotoxigenic Escherichia coli is the heat-labile enterotoxin (LT), an AB5 toxin closely related to the cholera toxin. LT consists of six subunits, the catalytically active A-subunit and ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)The NMR chemical shift has been the most versatile marker of chemical structures, by reflecting global and local electronic structures, and is very sensitive to any change within the chemical species. In this work, Ru(II) ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)In vitro derived simplified 3D representations of human organs or organ functionalities are predicted to play a major role in disease modeling, drug development, and personalized medicine, as they complement traditional ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)A new analogue of gambierone, 44-methylgambierone, was isolated from the benthic dinoflagellate Gambierdiscus australes collected from Raoul Island (Rangitahua/Kermadec Islands). This molecule has been previously reported ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The naturally occurring peptide indolicidin from bovine neutrophils exhibits strong biological activity against a broad spectrum of microorganisms. This is believed to arise from selective interactions with the negatively ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2019)Phosphoramides are an interesting alternative to the thiourea motif that has long been used in organocatalysis. In the R1N(H)-P(O)(R3)-N(H)R2 formulation, phosphoramides give the advantage of having a third variable ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The catalytic mechanism of the cyclic amidohydrolase isatin hydrolase depends on a catalytically active manganese in the substrate-binding pocket. The Mn2+ ion is bound by a motif also present in other metal dependent ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)A highly asymmetric AuIII η3‐allyl complex has been generated by treating Au(η1‐allyl)Br(tpy) (tpy=2‐(p‐tolyl)pyridine) with AgNTf2. The resulting η3‐allyl complex has been characterized by NMR spectroscopy and X‐ray ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Proton-transfer-reaction mass spectrometry (PTR-MS) is seeing an increased use of NH4+ ions for the detection of amines and labile oxygenated organic compounds. NH4+ ions are usually generated from ammonia or ammonium-containing ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Interactions of a stationary external magnetic field with the spin and orbital magnetic momenta of a molecule are included in the quantum mechanical model where the Born–Oppenheimer approximation is not assumed. The model ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Many laboratory courses consist of short and seemingly unconnected individual laboratory exercises. To increase the course consistency, relevance, and student engagement, we have developed a research‐inspired and project‐based ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)A state-specific multireference coupled-cluster (MRCC) method based on Arponen’s bivariational principle is presented, the bivar-MRCC method. The method is based on single-reference theory and therefore has a relatively ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Reactions between alkenes and methanol or dimethyl ether (DME) on zeolite catalysts are involved in industrial processes that are highly relevant for the transition to renewable carbon sources, such as the Methanol-To-Hydrocarbons ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Herein, we report the discovery of a toroidal inorganic cluster of zirconium(IV) oxysulfate of unprecedented size with the formula Zr70(SO4)58(O/OH)146⋅x(H2O) (Zr70), which displays different packing of ring units and thus ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Transition metal containing polyanion compounds are effective excellent electrode materials for sodium-ion batteries due to their high intrinsic electrochemical potentials and to the resulting high energy density. Iron ...
-
(Doctoral thesis / Doktoravhandling, 2021)Hydrogen will play a key role in a zero-emission society, and proton (H+) conducting oxides have gained interest as solid-state electrolytes for next-generation electrochemical devices for fuel cells and electrolyzers. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Vapor–liquid equilibria data of three poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide)/water liquid crystals (LCs) with CO2 has been obtained up to 6 bar. The investigated LCs consist of 60% (EO)3(PO)50(EO)3 ...
