(Peer reviewed; Journal article, 2018)The synthesis of two marine natural products containing a 3-alkylidene-6-arylidene-2,5-diketopiperazine scaffold by employing two consecutive aldol condensations starting with 1,4-diacetyl-2,5-diketopiperazine is reported. ... -
Alkylation of TEB Acetylide Using Tosylates
(Master thesis, 2018-12-19)Alkylated products of 3,3,4,4-tetraethoxybut-1-yne (TEB) where prepared from alkylation of the TEB acetylide with a selection of alkyl tosylates, obtained by tosylation of the corresponding tosylates, and alkyl iodides in ... -
Alkylfenolers innvirkning på glyserofosfolipidmembraner og kolesterol i torskehjerne
(Master thesis, 2003)Oljeindustrien slipper ut store mengder produsert vann, som inneholder flere potensielle giftstoffer, blant annet alkylfenoler. Det ble tidlig vist at alkylfenoler kan ha skadelig virkning, særlig på grunn av østrogenhermende ... -
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 ... -
