Diffusion in heterogeneous polymer systems : a nuclear magnetic resonance study
(Dr. ingeniøravhandling, 0809-103X; 2000:112, Doctoral thesis, 2000)Both enantiomers of 1-(1,3-dithian-2-yl)-2-propanol (5) 1-(1,3-dithiolan-2-yl)-2-propanol (6), and halogenated derivatives of 5 was obtained by microbial reductions and lipase catalyzed esterifications. (2S)-1-(1,3-dithi ... -
Diffusion of gas mixtures in the sI hydrate structure
(Journal article; Peer reviewed, 2018)Replacing methane with carbon dioxide in gas hydrates has been suggested as a way of harvesting methane, while at the same time storing carbon dioxide. Experimental evidence suggests that this process is facilitated if gas ... -
Direct conversion of CO2 to gasoline over Na-Fe3O4+ HZSM-5 and/or SAPO-11
(Bachelor thesis, 2021)Katalytisk hydrogenering av CO2 kan bidra til å senke det totale utslipp av CO2 og til produksjon av nyttige brensel som for eksempel bensin. Na-Fe3O4 kombinert med ZSM-5 og/eller SAPO-11 er katalysatorer kan brukes til å ... -
Directed Lithiation of Protected 4-Chloropyrrolopyrimidine: Addition to Aldehydes and Ketones Aided by Bis(2-dimethylaminoethyl)ether
(Peer reviewed; Journal article, 2023)Pyrrolopyrimidines are important scaffolds for the preparation of bioactive molecules. Therefore, developing efficient and flexible ways for selective functionalization of the pyrrolopyrimidine skeleton is of interest. We ... -
Distribution and patterns of rare earth elements in marine organisms in the Trondheim fjord
(Master thesis, 2022)Den økende utvinningen og bruken av sjeldne jordarter (REEs) fører til en økning i utslipp og konsentrasjoner av disse metallene i marine miljøer. I denne oppgaven ble makroalger, blåskjell og brunkrabber brukt til å ... -
Distribution and Variation of the Trace Metal Iron in the Base of the Pelagic Marine Food Web: A Mesocosm Approach: Trace Metal in marine biology
(Master thesis, 2012)This study was part of the WAFOW project “Can waste emission from fish farms change the structure of marine food webs?” whose objective was to perform mesocosms experiment to simulate the ammonium enriched environment, ... -
Distribution of PAHs, PCBs, and PCDD/Fs in products from full-scale relevant pyrolysis of diverse contaminated organic waste
(Peer reviewed; Journal article, 2023)Biomass pyrolysis is the anoxic thermal conversion of biomass into a carbon rich, porous solid, often called biochar. This could be a better waste management alternative for contaminated organic wastes than incineration, ... -
The distribution of persistent, mobile and toxic (PMT) pharmaceuticals and personal care products monitored across Chinese water resources
(Peer reviewed; Journal article, 2021)Hazard classifications have recently been introduced for persistent, mobile and toxic (PMT) and very persistent and very mobile (vPvM) substances, which are those that negatively impact water resources if substantially ... -
Distribution of selenium in the plume of the Gediz River, Izmir Bay, Aegean Sea
(Journal article; Peer reviewed, 2017)Selenium (Se) variations in the water column, suspended particulate matter, and sediment through the salinity gradient, together with water-quality parameters, were investigated over four different river conditions: ... -
Distribution pattern of mercury in northern Barents Sea and Eurasian Basin surface sediment
(Peer reviewed; Journal article, 2022)Marine sediment is a significant sink for the global pollutant mercury. In a rapidly changing Arctic region, mercury (Hg) bioaccumulation in the marine ecosystem remains a prominent environmental issue. Here, we report ... -
