Fabrication of large free-standing nanostructured zone plates for focusing a Bose-Einstein condensate
(The University of Bergen, 2017-09-20)Matter wave optics is a fascinating area of physics touching many scientific disciplines ranging from microscopy to high precision gravity measurements. One of the major recent breakthroughs was the realization in 1995 of ...Master thesis -
Non-Polar Natural Products from Bromelia laciniosa, Neoglaziovia variegata and Encholirium spectabile (Bromeliaceae)
(MDPI, 2017-09-06)Extensive regional droughts are already a major problem on all inhabited continents and severe regional droughts are expected to become an increasing and extended problem in the future. Consequently, extended use of available ...Journal article -
Aerobic fitness and metabolic health in children: A clinical validation of directly measured maximal oxygen consumption versus performance measures as markers of health
(Elsevier, 2017-09)High aerobic fitness is consistently associated with a favorable metabolic health profile in children. However, measurement of oxygen uptake, regarded as the gold standard for evaluating aerobic fitness, is often not ...Journal article -
Characterization of complex solutions using relaxation- and diffusion weighted NMR Spectroscopy.
(The University of Bergen, 2017-08-02)The need for a sustainable replacement to the conventional fossil fuels is required. Biooils is a potential replacement. The biooil analyzed in this thesis is made from lignin, which is a by-product of paper production. ...Master thesis -
Oil droplet fouling and differential toxicokinetics of polycyclic aromatic hydrocarbons in embryos of Atlantic haddock and cod
(PLOS, 2017-07-05)The impact of crude oil pollution on early life stages (ELS) of fish, including larvae and embryos, has received considerable attention in recent years. Of the organic components present in crude oil, polycyclic aromatic ...Journal article -
Synthesis of a novel tripeptidomimetic scaffold and biological evaluation for CXC chemokine receptor 4 (CXCR4) antagonism
(Elsevier, 2017-07)We here report the preparation of a new 2,6,8-trisubstituted bicyclic tripeptidomimetic scaffold through TFA-mediated cyclization of a linear precursor containing three side chains. The introduction of a triphenylmethyl-protected ...Journal article -
Optical properties of metal nanoparticles investigated using polarised light.
(The University of Bergen, 2017-06-10)The number of applications of metal nanoparticles (MNPs) are growing, and one of their most interesting properties is the interactions between MNPs and light. Especially in the visible regime, MNPs are very good at absorbing ...Master thesis -
Direct Injection Electrospray Mass Spectrometry (DI-ESI-MS) and Liquid Chromatography Electrospray Mass Spectrometry (LC-ESI-MS) method development for characterisation of organic acids in petroleum and bio-oil samples
(The University of Bergen, 2017-05-09)Analysis and characterisation of complex mixtures such as petroleum and bio-oils are unarguably challenging. Finding suitable analytical method therefore needs to be considered carefully by analytical chemists. Electrospray ...Master thesis -
