Amino-Functionalised Pillared-Layered Metal-Organic Frameworks: Characterisation and Selective Adsorption Properties
(Master thesis, 2021-06-01)Materials technology, with the focus of discovery of new materials which are tailor-designed with a very particular set of properties suitable for application, has provided essential developments for the modern society ... -
Analyse av forbindelser av høymolekylær vekt i pollen ved bruk av termokjemolyse-GC-MS og FT-IR
(Master thesis, 2016-11-21)Organisk materiale inneholder komplekse polymerer med høy molekylvekt og stor kjemisk stabilitet, som det er vanskelig å analysere med tradisjonelle metoder. Termokjemolyse er en teknikk som kan omdanne de komplekse ... -
Analyse og derivatisering av fenolar i biooljer
(Master thesis, 2011-06-01)Dagens samfunn er i stor grad avhengige av fossile brensel for å kunne fungere, og med fleire folkerike land i rask økonomisk vekst, er det venta at forbruket av fossile brensel vil auke ytterlegare i åra framover. Dette ... -
An Analysis of CO2, CH4 and Mixed CO2-CH4 Gas Hydrates: Experimental Phase Equilibria Measurements and Simulations with State-of-the-Art Software
(Master thesis, 2014-06-14)The enormous amount of CH4 trapped in gas hydrates has led to a growing focus on gas hydrates as a potential future energy source. One of the proposed methods for the production of CH4 from these deposits, is to exchange ... -
Analysis of Fatty Acids by High Performance Liquid Chromatography and Electrospray Ionization-Mass Spectrometry
(Master thesis, 2019-09-28)Fatty acids (FA) have been traditionally analyzed by gas chromatography (GC) as fatty acids methyl esters (FAME) and more recently using mass spectrometry (MS) detection. Since high performance liquid chromatography (HPLC) ... -
Analysis of the flavonoids and phenolics found in the marine angiosperm Plantago maritima collected in Norway
(Master thesis, 2023-05-11)This master project has a focus on extraction, separation and identification of flavonoids and other phenolic compounds in Plantago maritima. Previously in Norway there has only been done one small pilot study (bachelor ... -
Analysis of the marine sponge Pachymatisma normani
(Master thesis, 2020-06-12)Marine sponges are evolutionary some of the oldest multicellular organisms on earth and have in the last few decades attracted an increasing amount of attention. Sponges are simple filter feeders that host symbiotic ... -
