Optimization of Separation Efficiency in Temperature Programmed Gas Chromatography : Application of Response Surface Methodology
(Master thesis, 2014-03-14)Chromatographic efficiency can be defined as the maximal number of chromatographic peaks that can be separated within a section of a chromatogram. In isothermal gas chromatography (GC) it is usually measured by number of ... -
Optimized bisubstrate inhibitors for the actin N-terminal acetyltransferase NAA80
(Journal article; Peer reviewed, 2023)Acetylation of protein N-termini is one of the most common protein modifications in the eukaryotic cell and is catalyzed by the N-terminal acetyltransferase family of enzymes. The N-terminal acetyltransferase NAA80 is ... -
Optimizing the Liquid Target Production of the PET-radionuclide Ti-45 from a Natural Scandium Target
(Master thesis, 2022-09-15)The search for novel PET-nuclides is an ongoing process as some applications require decay characteristics that are different from the conventional ones. The use of novel radionuclides will fill the gap between conventional ... -
Oriented self-assembly of anisotropic layered double hydroxides (LDHs) with 2D-on-3D hierarchical structure
(Journal article; Peer reviewed, 2023)Layered double hydroxides (LDHs) have been the subject of increasing research due to their unique 2D or 3D structures and promising applications. However, achieving precise control over their morphology and architecture ... -
Origin and character of gaseous hydrocarbons in the hydrate and non-hydrate charged sediments on the Norway - Svalbard margins
(Doctoral thesis, 2011-05-26)Gas incubated in clathrate water-structures, stabilizes the hydrogen bonded substance termed gas hydrate. In the marine environment vast amount of carbon is stored as gas hydrates within the temperature and pressure zone ... -
Osmotic engine converting energy from salinity difference to a hydraulic accumulator by utilizing polyelectrolyte hydrogels
(Journal article; Peer reviewed, 2021)Efficient harvesting of the mixing energy from the salinity gradient between sea and river water remains a challenge. Recently, utilization of the swelling/shrinking properties of hydrogels has been explored as a new means ... -

Partially carbonized wastepaper with excellent mechanical strength for oil-water and emulsion separation
(Journal article; Peer reviewed, 2023)Background Taking the treatment of oily sewage and the recycling of wastepaper as the starting point, the idea of using waste to treat waste was used to treat the swage with aerogels made of wastepaper. Methods Porous ... -
Partielle molare eigenskapar og løysingsevne til kalsiumfosfat ved høgtrykk studert ved hjelp av volum og kompresjon av natriumfosfat og kalsiumkolrid
(Master thesis, 2003)Det har vorte utført tettleiksmålingar og lydfartsmålingar på vassløysningar av natriumdihydrogenfosfat, dinatriumhydrogenfosfat, trinatriumfosfat og kalsiumklorid. Målingane har vorte gjort for ulike konsentrasjonar i ... -
PDBe-KB: collaboratively defining the biological context of structural data
(Journal article; Peer reviewed, 2022)The Protein Data Bank in Europe – Knowledge Base (PDBe-KB, https://pdbe-kb.org) is an open collaboration between world-leading specialist data resources contributing functional and biophysical annotations derived from or ... -
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 ... -
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 ... -
