Low temperature methanol synthesis catalyzed by copper nanoparticles 
Ahoba-Sam, Christian; Olsbye, Unni; Jens, Klaus-Joachim (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A one pot catalytic system which involves Cu and an alkoxide co-catalyst has been used for methanol (MeOH) synthesis at low temperature. Up to about 92% syngas conversion per pass and more than 90% selectivity to MeOH (the ...
A fundamental catalytic difference between zinc and manganese dependent enzymes revealed in a bacterial isatin hydrolase 
Sommer, Theis; Bjerregaard-Andersen, Kaare; Uribe, Lalita; Etzerodt, Michael; Diezemann, Gregor; Gauss, Jürgen; Cascella, Michele; Morth, Jens Preben (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 ...
Burst nucleation by hot injection for size controlled synthesis of ε-cobalt nanoparticles 
Zacharaki, Eirini; Kalyva, Maria; Fjellvåg, Helmer; Sjåstad, Anja O (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
Analytic cubic and quartic force fields using density-functional theory 
Ringholm, Magnus; Jonsson, Dan Johan; Bast, Radovan; Gao, Bin; Thorvaldsen, Andreas johan; Ekstrøm, Ulf; Helgaker, Trygve; Ruud, Kenneth (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
We present the first analytic implementation of cubic and quartic force constants at the level of Kohn–Sham density-functional theory. The implementation is based on an open-ended formalism for the evaluation of energy ...
Redetermined crystal structure of α-dl-methionine at 340 K 
Gørbitz, Carl Henrik; Qi, Lianglin; Mai, Ngan Thi Kim; Kristiansen, Håvard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
Two forms, α and β, are known for the racemic amino acid DL-me­thio­nine, C5H11NO2S. The phase transition between them, taking place around 326 K, is associated with sliding at the central inter­faces of the hydro­phobic ...
Structural and magnetic aspects of La4(Co1-xNix)3O10+δ (0 ≤ x ≤ 1) 
Nagell, Marius Uv; Kumar, Susmit; Sørby, Magnus Helgerud; Fjellvåg, Helmer; Sjåstad, Anja Olafsen (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2015)
The Ruddlesden–Popper (RP3) type oxides, La4Co3O10+δ and La4Ni3O10+δ, form a complete solid solution. Powder X-ray and neutron diffraction data show that La4(Co1−xNix)3O10+δ is isostructural to the monoclinic La4Co3O10+δ ...
Open tubular lab-on-column/mass spectrometry for targeted proteomics of nanogram sample amounts 
Hustoft, Hanne Kolsrud; Vehus, Tore; Brandtzæg, Ole Kristian Merkesvik; Krauss, Stefan; Greibrokk, Tyge; Wilson, Steven Ray Haakon; Lundanes, Elsa (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
A novel open tubular nanoproteomic platform featuring accelerated on-line protein digestion and high-resolution nano liquid chromatography mass spectrometry (LC-MS) has been developed. The platform features very narrow ...
Highly automated nano-LC/MS-based approach for thousand cell-scale quantification of side chain-hydroxylated oxysterols[S] 
Røberg-Larsen, Hanne; Lund, Kaja; Vehus, Tore; Hoen, Nina; Vesterdal, Caroline; Misaghian, Dorna; Olsen, Peter Angell; Krauss, Stefan; Wilson, Steven Ray Haakon; Lundanes, Elsa (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
Iso-octyl chain-hydroxylated oxysterols were determined in attomoles per 10,000 cells concentrations in 10,000–80,000 cultured pancreatic adenocarcinoma cells, using a sensitive, highly automated nano-LC-ESI-MS-based method. ...
Investigation of Theoretical Models for the Elastic Stiffness of Nanoparticle-Modified Polymer Composites 
Thorvaldsen, Tom; Johnsen, Bernt Brønmo; Olsen, Torbjørn; Hansen, Finn Knut (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
Mathematical models are investigated and suggested for the calculation of the elastic stiffness of polymer nanocomposites. Particular emphasis is placed on the effect on the elastic stiffness from agglomerates and the ...
Liquid chromatography-mass spectrometry platform for both small neurotransmitters and neuropeptides in blood, With Automatic and robust solid phase extraction 
Johnsen, Elin Follaug; Lundanes, Elsa; Wilson, Steven Ray Haakon; Leknes, Siri (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
Neurons communicate via chemical signals called neurotransmitters (NTs). The numerous identified NTs can have very different physiochemical properties (solubility, charge, size etc.), so quantification of the various NT ...
