Fremstilling av et kiralt triazoliumbasert NHC-salt og anvendelse i asymmetrisk syntese
(Master thesis, 2011)Et kiralt triazoliumbasert N-heterosykliskkarben-salt (NHC) 1 har blitt fremstilt fra L-fenylalanin 2 og fenylhydrazinhydroklorid 12 i en synteserute som går over fem trinn, og med et totalutbytte på 10%. NHC-salt 1 er ... -
Fremstilling av kirale stoffer mot humane sopp-plager
(Master thesis, 2011)En serie med sju enantiomert rene Butenafine-derivater, 1a-g, ble fremstilt.Forbindelsene 1a-f ble fremstilt fra det sekundære metylaminet 2 og forskjelligebenzylhalider, 5a-f. Benzylhalidene 5a-f var substituert på ... -
Fremstilling av propargylestere og anvendelse i gullkatalyserte reaksjoner
(Master thesis, 2011)Hovedmålet i masteroppgaven har vært å utforske nye gullkatalyserte reaksjoner og anvendelser av propargylestere og allenestere. Allen 14, ble syntetisert fra propargylbromid over to trinn, ved en kjent prosedyre. Kationiske ... -
Fremstilling og karakterisering av potensielle virkestoffer mot sopp og protozoer
(Master thesis, 2008)Det er syntetisert fire potensielle virkestoffer mot sopp. To av disse er fluorerte forbindelser. -
Frequency controlled agglomeration of pt-nanoparticles in sonochemical synthesis
(Peer reviewed; Journal article, 2022)Optimizing the surface area of nanoparticles is key to achieving high catalytic activities for electrochemical energy conversion devices. In this work, the frequency range (200 kHz–500 kHz) for maximum sonochemical radical ... -
Frequency dependent polarisation switching in h-ErMnO3
(Journal article; Peer reviewed, 2018)We report an electric-field poling study of the geometric-driven improper ferroelectric h-ErMnO3. From a detailed dielectric analysis we deduce the temperature and frequency dependent range for which single-crystalline ... -
Fresh and frozen stored fillets of Atlantic mackerel (Scomber scombrus)– effect on oxidation and sensory quality of canned mackerel fillets
(Chapter, 2016)Atlantic mackerel caught off the West Coast of Norway were filleted and frozen in 20 kg blocks at landing. The fillets were canned with tomato sauce when fresh and after 1, 3, 6, 9 and 12 months of frozen storage. The ... -
Freshwater Fish Community Responses to Climate Change and Invasive Species
(Doctoral theses at NTNU;2021:27, Doctoral thesis, 2021)Despite making up only a tiny proportion of the world’s aquatic surface area, freshwater ecosystems are home to a plethora of biodiversity, containing roughly 40% of all described fish species. Yet they’re also among the ... -
