Towards the Synthesis of β-Hydroxy 1,3-Dithiane Derivatives
(Master thesis, 2019-10-03)The β-hydroxy dithiane, 3-(1,3-dithiane-2-yl)-1,1-diethoxypropan-2-ol, was synthesized from the versatile synthon 3,3,4,4-tetraethoxybut-1-yne (TEB). 1,1-Diethoxy-3-(2-methyl-1,3- dithian-2-yl)propan-2-ol was successfully ... -
Toxicological evaluation of complex mixtures by pattern recognition: Correlating chemical fingerprints to mutagenicity
(Journal article, 2002-12)We describe the use of pattern recognition and multivariate regression in the assessment of complex mixtures by correlating chemical fingerprints to the mutagenicity of the mixtures. Mixtures were 20 organic extracts of ... -
Transport of polymer particles in oil–water flow in porous media: Enhancing oil recovery
(Peer reviewed; Journal article, 2019)We study a heuristic, core-scale model for the transport of polymer particles in a two-phase (oil and water) porous medium. We are motivated by recent experimental observations which report increased oil recovery when ... -
Ultralydsmålinger under høyt trykk - En undersøkelse av solubilisering av 1-heksanol i natrium dodecylsulfat som funksjon av trykk
(Master thesis, 2005)Ny apparatur for lydhastighetsmålinger under trykk har blitt testet, og tilpasset rubidium-klokke teknikk. Det ble deretter gjort studier på solubiliseringsprosessen som funksjon av trykk, der en variert mengde av 1-heksanol ... -
Undersøkelse av effekten av katalysatorer og støttematerialer på omdanningen av lignin til LtL-biooljer ved forskjellige betingelser
(Master thesis, 2014-12-19)Verdens petroleumsforbruk har skutt i været de siste tiårene, og man inser at ressursene holder på å gå tom. Dette har tvunget oss til å begynne å tenke på alternative måter å produsere energi og drivstoff på. Lignocellulosisk ... -
