Identification and quantification of valuable platform chemicals in aqueous product streams from a preliminary study of a large pilot-scale steam explosion of woody biomass using quantitative nuclear magnetic resonance spectroscopy
(Journal article; Peer reviewed, 2022)Steam explosion breaks down the polymeric matrix and enables the recovery of valuable compounds from lignocellulosic feedstock. In the steam explosion process, biomass is treated with high-pressure steam which subsequently ... -
Korleis kan oppsett for forsøk påverke rapportar i kjemifaget?
(Master thesis, 2022-06-01)Praktisk arbeid med forsøk og demonstrasjonar er ein sentral del av kjemifaget. I etterkant av praktisk arbeid brukar elevane ofte å skrive ein forsøksrapport. Læraren har medverknad over desse faktorane: kva forsøk som ... -
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 ... -
Imidazole Backbone Functionalization with Olefin Cross-Metathesis
(Journal article; Peer reviewed, 2022)A selective and high-rate Ru-catalyzed cross-metathesis reaction of alkenes with vinylimidazole is disclosed. Cross-metathesis is known to operate less efficiently on N-heterocycles, but through optimization by means of ... -
Geometric Frustration on the Trillium Lattice in a Magnetic Metal-Organic Framework
(Journal article; Peer reviewed, 2022)In the dense metal-organic framework Na[Mn(HCOO)3], Mn2+ ions (S=52) occupy the nodes of a “trillium” net. We show that the system is strongly magnetically frustrated: the Néel transition is suppressed well below the ... -
Immiscible Viscous Fingering: Modelling Unstable Water–Oil Displacement Experiments in Porous Media
(Journal article; Peer reviewed, 2022)Viscous fingering in porous media occurs when the (miscible or immiscible) displacing fluid has a lower viscosity than the displaced fluid. For example, immiscible fingering is observed in experiments where water displaces ... -
Comparison of calibration models for rapid prediction of lignin content in lignocellulosic biomass based on infrared and near-infrared spectroscopy
(Journal article; Peer reviewed, 2022)Lignocellulosic biomass has great potential as a renewable energy source due to abundance both as vegetation and in residues from agriculture and forestry. It can be utilized for biofuels and for value-added chemicals and ... -
Hydrothermal liquefaction of sewage sludge anaerobic digestate for bio-oil production: Screening the effects of temperature, residence time and KOH catalyst
(Journal article; Peer reviewed, 2022)Due to sewage sludge being an abundant biobased resource, and with the number of biogas plants utilizing sewage sludge increasing, digested sewage sludge (DSS) is a promising feedstock for producing bio-oil. This study ... -
The Consistency of Yields and Chemical Composition of HTL Bio-Oils from Lignins Produced by Different Preprocessing Technologies
(Journal article; Peer reviewed, 2022-06-27)This work evaluates the effect of feedstock type and composition on the conversion of lignin to liquid by solvolysis with formic acid as hydrogen donor (LtL), by analyzing the yields and molecular composition of the liquid ... -
Investigating solids present in the aqueous stream during STEX condensate upgrading—a case study
(Journal article; Peer reviewed, 2022)Steam explosion (STEX) of woody biomass is an efficient pretreatment method in the production of water-resistant wood pellets. The STEX process also generates an aqueous condensate stream containing dissolved organic ... -
Structure of POPC Lipid Bilayers in OPLS3e Force Field
(Journal article; Peer reviewed, 2022)It is crucial for molecular dynamics simulations of biomembranes that the force field parameters give a realistic model of the membrane behavior. In this study, we examined the OPLS3e force field for the carbon−hydrogen ... -
Dissecting peripheral protein-membrane interfaces
(Journal article; Peer reviewed, 2022-12-14)Peripheral membrane proteins (PMPs) include a wide variety of proteins that have in common to bind transiently to the chemically complex interfacial region of membranes through their interfacial binding site (IBS). In ... -
PDBe-KB: collaboratively defining the biological context of structural data
