(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 antocyaner i bjørnebær (Rubus fruticosus)
(Master thesis, 2010)Tema for denne oppgaven er analyse av antocyaner i bjørnebær. Antocyaner er naturlige pigmenter som gir opphav til farger varierende fra oransje og rød til fiolette og blå i blomster, frukt og andre planter (Melo et al. ... -
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 ... -
