Bruk av koblingskjemi i fremstilling av bioaktive tienopyrimidiner
(Master thesis, 2011)Ved bruk av koblingskjemi har tre forskjellige synteseruter blitt utforsket. Disse tre rutene har blitt benyttet til å fremstille ti potensielt biologisk aktive tienopyrimidiner. Hovedvekten av arbeidet har ligget i å ... -
Capillary forces and osmotic gradients in salt water - oil systems
(Master thesis, 2012)This project looks at the capillary systems with salt water and oil that can be found in porous stones in oil reservoir. The interactions between the different phases and how salt concentration differences can move the ... -
Electrochemical reactions of Carboxylic Acids and product identification
(Master thesis, 2011)ABSTRACT -
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 ... -
Gold(I) Catalyzed Tandem Cyclization Reactions
(Master thesis, 2012)Through this study it has been observed that in contrast to propargyl esters which give cyclopropyl products, the high reactivity of propargyl acetals allows a new tandem cyclization to take place, resulting in bicyclic ... -
Growth and Characterization of Silicon Nanowires for Solar Cell Applications
(Master thesis, 2011)Si-nanowires are being introduced as an attempt to decrease the high recombination rate present in silicon based thin-film solar cells by employing radial pn-junctions instead of conventional planar pn-junctions. Previous ... -
HF Formation Upon Addition of Different Industrial Aluminas to Cryolitic Baths
(Master thesis, 2011)The aluminium smelter at Hydro Sunndal has experienced problems with an unexpected increased loss of AlF3 from the electrolyte when using a certain quality of alumina. One hypothesis considered was that the fluoride loss ... -
Nanostructuring of Oxygen Permeable Membranes by Chemical Etching Techniques
(Master thesis, 2011)Mixed ionic electronic conducting ceramic oxides are being investigated for use as membranes for oxygen separation from air and as electrodes in solid oxide fuel cells [1, 2]. Oxygen surface exchange rate is an important ... -
Screening of Inhibitors for Amine Degradation
(Master thesis, 2012)Hindering the degradation of amines in the CO2-capturing process is important both for economical purposes when it comes to loss of solvent and impacts on the process, and to prevent emissions of volatile degradation ... -
Synthesis of a Precursor for a Carotenoid Cationic Lipid
(Master thesis, 2012)The goal of this work was the synthesis of a carotenoid cationic lipid for the research of carriers of nucleic acids into defective cells via transfection therapy. In the course of this project a precursor for the carotenoid ... -
Upgrading off-grades from the silicon process: Increasing the silicon yield from Elkem Thamshavn using mechanical or metallurgical separation
(Master thesis, 2011)The aim of the thesis is to produce high grade silicon from off-grade materials like sculls and process slags from Elkem Thamshavn. The methods investigated are dense medium separation, optical separation, flotation and ... -
Vinyl Amide Reactions in the Presence of Gold(I) Catalyst
(Master thesis, 2012)Reaksjoner med vinylderivater i nærvær av gull(I)katalysator. Sykloaddisjoner og dimeriseringsreaksjoner er studert.
