Recovered Energy from Salinity Gradients Utilizing Various Poly(Acrylic Acid)-Based Hydrogels
(Journal article; Peer reviewed, 2021-02-22)Hydrogels can be utilized to extract energy from salinity gradients when river water mixes with seawater. Saline-sensitive hydrogels exhibit a reversible swelling/shrinking process when they are, alternately, exposed to ... -
Redesigning Clozapine : Development of Clozapine Analogues for the Potential Treatment of Melanoma Brain Metastases
(Doctoral thesis, 2024-11-22)Kreft er den nest vanligste dødsårsaken i Europa. Mangelen på selektiviteten mellom vev danner bivirkninger, uavhengig om behandlingstype. Utvikling av nye behandlinger kan ta opptil 15 år og er kostbart. Gjenbruk av ... -
Reduction in flavor-intense components in fish protein hydrolysates by membrane filtration
(Journal article; Peer reviewed, 2021)Enzymatic protein hydrolysates based on side stream materials from the fish-filleting industry are increasingly explored as food ingredients. However, intense sensory properties, and high salt contents, are often a limiting ... -
Relationship Between Crude Oil Composition and Physical-Chemical Properties
(Master thesis, 2016-06-01)Improving oil recovery by low salinity waterflooding has been of interest in both laboratories and fields in recent years. Understanding how the underlying mechanism affects the final recovery is necessary in order to ... -
Relative Spatial Positions of Tryptophan and Cationic Residues in Helical Membrane-active Peptides Determine Their Cytotoxicity
(Journal article; Peer reviewed, 2012)The cytotoxic activity of 10 analogs of the idealized amphipathic helical 21-mer peptide (KAAKKAA)3, where three of the Ala residues at different positions have been replaced with Trp residues, has been investigated. The ... -
A reliable external calibration method for reaction monitoring with benchtop NMR
(Journal article; Peer reviewed, 2023)Nuclear magnetic resonance (NMR) spectroscopy is a powerful analytical technique with the ability to acquire both quantitative and structurally insightful data for multiple components in a test sample. This makes NMR ... -
Revealing the secrets of proteins: A triple-nuclear and multi-dimensional high-resolution NMR spectroscopy study
