(Master thesis, 2023-09-30)Polyphenols are an extensive group of compounds with important antioxidant properties, whose industrial use has shown a continuous increase in the last years. Their utilization in aquaculture is becoming progressively ... -
Exploring the Fermentation Parameters of Kombucha on Caffeine and pH Using Experimental Design and the Feasibility of Raman Spectroscopy in Kombucha Analysis
(Master thesis, 2023-09-30)Kombucha shows promising growth potential due to its claimed health benefits. Through an experimental design, the impact of the fermentation parameters on color and appearance, pH and caffeine content was further understood ... -
Probing the elastic response of lipid bilayers and nanovesicles to leaflet tensions via volume per lipid
(Journal article; Peer reviewed, 2023)Biological and biomimetic membranes are based on lipid bilayers, consisting of two monolayers or leaflets. One important but challenging physical parameter of these membranes is their tension. For a long time, this tension ... -
A Saddle-Shaped Expanded Porphyrinoid Fitting C60**
(Journal article; Peer reviewed, 2023)We present the synthesis of a new type of an expanded porphyrinoid macrocycle with a saddle-shaped morphology and its complexation of C60 guest molecules. The new macrocycle contains four carbazole and four triazole moieties ... -
Selectivity study on thermochemical conversion of fruit residues (Plums) to platform chemicals (HMF)
(Master thesis, 2023-09-30)5-hydroxymethylfurfural (HMF) is one of the versatile platform compounds derived from the dehydration of carbohydrates originating from biomass. However, the non-selective production of HMF from carbohydrates and its ... -

Co-exposure to UV radiation and crude oil increases acute embryotoxicity and sublethal malformations in the early life stages of Atlantic haddock (Melanogrammus aeglefinus)
(Journal article; Peer reviewed, 2023)Crude oil causes severe abnormalities in developing fish. Photomodification of constituents in crude oil increases its toxicity several fold. We report on the effect of crude oil, in combination with ultraviolet (UV) ... -
Alkyl-phenanthrenes in early life stage fish: differential toxicity in Atlantic haddock (Melanogrammus aeglefinus) embryos
(Journal article; Peer reviewed, 2023)Tricyclic polycyclic aromatic hydrocarbons (PAHs) are believed to be the primary toxic components of crude oil. Such compounds including phenanthrene are known to have direct effects on cardiac tissue, which lead to ... -
Probing Catalyst Degradation in Metathesis of Internal Olefins: Expanding Access to Amine-Tagged ROMP Polymers
(Journal article; Peer reviewed, 2023)Ruthenium-promoted ring-opening metathesis polymerization (ROMP) offers potentially powerful routes to amine-functionalized polymers with antimicrobial, adhesive, and self-healing properties. However, amines readily degrade ... -
Comparing the adsorption of methyl orange and malachite green on similar yet distinct polyamide microplastics: Uncovering hydrogen bond interactions
(Journal article; Peer reviewed, 2023)Microplastics (MPs) and dye pollutants are widespread in aquatic environments. Here, the adsorption characteristics of anionic dye methyl orange (MO) and cationic dye malachite green (MG) on polyamide 6 (PA6) and polyamide ... -
Adsorption Behavior of Diclofenac on Polystyrene and Poly(butylene adipate-co-terephthalate) Microplastics: Influencing Factors and Adsorption Mechanism
(Journal article; Peer reviewed, 2023)To unveil the intricacies surrounding the interaction between microplastics (MPs) and pollutants, diligent investigation is warranted to mitigate the environmental perils they pose. This exposition delves into the sorption ... -
Mesomeric Acceleration Counters Slow Initiation of Ruthenium-CAAC Catalysts for Olefin Metathesis (CAAC = Cyclic (Alkyl)(Amino) Carbene)
(Journal article; Peer reviewed, 2023)Ruthenium catalysts bearing cyclic (alkyl)(amino)carbene (CAAC) ligands can attain very high productivities in olefin metathesis, owing to their resistance to unimolecular decomposition. Because the propagating methylidene ... -
Analysis of Polyphenols from Laminaria hyperborea for application as Life Science ingredients
(Doctoral thesis, 2023-09-01)Makroalger, også kjent som tang og tare, er anerkjent som en verdifull kilde til bioaktive forbindelser. Av disse har polyfenoler fått særlig oppmerksomhet. Polyfenoler har blitt assosiert med en rekke helsefordeler, og ... -
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 ... -
One-step preparation of robust elastic plastic polyvinyl chloride sponges with a layered structure for highly efficient separation of water-in-oil emulsions
