(Doctoral thesis / Doktoravhandling, 2014)Gangliosides are sialic acid-containing glycosphingolipids expressed on all vertebrate cells. They are primarily positioned in the plasma membrane, with the ceramide part anchored in the membrane and the glycan part exposed ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)We report a mild superbase-catalyzed and nitrogen-selective carboxylation of N-heteroaryls, with subsequent alkylation enabling the synthesis of drug-like O-alkyl carbamates in good yields (av. 86%). Our findings suggest ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Nano liquid chromatography (nanoLC), with columns having an inner diameter (ID) of ≤100 μm, can provide enhanced sensitivity and enable analysis of limited samples. NanoLC has become an established tool in omics research, ...

A nano-silicate material with exceptional capacity for CO2 capture and storage at room temperature (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)In order to mitigate climate change driven by the observed high levels of carbon dioxide (CO2) in the atmosphere, many micro and nano-porous materials are being investigated for CO2 selectivity, capture and storage (CCS) ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)This study presents the adsorption capability of a filter composed of sand coated with cobalt nanomaterials (CoNM) for the extraction of manganese ions from aqueous media. The study was performed in both batch and dynamic ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Three-dimensional nanocrystalline Ag–C composites containing a hexagonal diamond structure were produced by electrochemical reduction of acetic acid and electrodeposition of Ag(NO3) (0.01 M) at −1.1 V vs Ag/AgCl at ambient ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)It is well known that liquids confined to small nanoscopic pores and droplets exhibit thermal behavior very different from bulk samples. Less is known about liquids spontaneously confined through self-assembly into micellar ...
-
(Master thesis / Masteroppgave, 2021)Point defects in semiconductors have emerged as viable candidates for quantumbased technologies such as quantum computing, communication, and sensing. The present work is related to quantum compatible point defects in ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Structural, electronic, and thermodynamic properties of native defects in GaS and GaSe monolayers are investigated by means of accurate ab initio calculations. Based on their charge transition levels we assess the influence ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The use of Pt–Rh catalysts is central in a number of industrial processes, and to explain their performance it is essential to have a solid understanding of their nanoscopic surface structure. Here we use scanning tunneling ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)A series of three neutral, hexacoordinate tin(IV) complexes were synthesized by the reaction of 4,4'‐dimethyl‐2,2'‐bipyridine (DMB) with SnX4, X = Cl, Br, and I, as starting materials. The complexes (DMB)SnX4 were characterized ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 1994)The nuclear and magnetic structures of ( Y 1 − x Ca x ) Ba 2 Fe 3 O 8 + δ with x=0.05, 0.10, and 0.20 have been investigated by neutron-powder diffraction at room temperature. The compound crystallizes with the symmetry ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 1992)The nuclear and magnetic structures of YBa 2 Fe 3 O 8 have been investigated by powder neutron diffraction at room temperature. The nuclear structure of the compound has the symmetry of space group P4/mmm and lattice ...
-
(Master thesis / Hovedoppgave, 2004)New chelating ligand systems were made and further complexed with platinum centers to give complexes for hydrocarbon C H activation. The first of the complexes was the [(1,1 -dimethyl-3,3 -methylene diimidazoline-2,2 ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)Hydride anion-conducting oxyhydrides have recently emerged as a brand new class of ionic conductors. Here we shed a first light onto their local vibrations, bonding mechanisms, and anion migration properties using the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Satellite-based measurements of the column CH2O/NO2 ratio have previously been used to estimate near-surface ozone (O3) sensitivity (i.e., NOx or VOC limited), and the forthcoming launch of air quality-focused geostationary ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Isoprene is the dominant nonmethane organic compound emitted to the atmosphere, where it drives ozone and aerosol production, modulates atmospheric oxidation, and interacts with the global nitrogen cycle. Isoprene emissions ...
