(Master thesis, 2012)In light of the increasing focus on sustainability and bio-mass as feedstock for energy and chemicals, extraction of hemicelluloses from different kinds of lignocellulosic materials has received much attention. This thesis ... -
How are popragylamines synthesised, how has the synthesis become greener and what are they used for?
(Bachelor thesis, 2023)Ulike syntese metoder for dannelse av propargylaminer har blitt analysert og metodene har blitt satt i tidsperspektiv. Det er to hoved typer måter propargylaminer kan bli dannet på. Først ved å substituere en funksjonell ... -
How do different nitrogen application levels and irrigation practices impact biological nitrogen fixation and its distribution in paddy system?
(Peer reviewed; Journal article, 2021)Background and aims Biological nitrogen fixation (BNF) in paddy systems is impacted by nitrogen application levels and irrigation strategies, but the extent to which these factors influence BNF and its distribution in ... -
How far can we stretch the timescale with RETIS?
(Peer reviewed; Journal article, 2023)Molecular dynamics (MD) and Monte Carlo (MC) have long coexisted as two main independent branches of molecular simulation. In the late eighties, however, algorithms based on the combination of both were created such as ... -
How relevant is the deposition of mercury onto snowpacks? - Part 1: A statistical study on the impact of environmental factors
(Journal article; Peer reviewed, 2012)A portion of the highly toxic methylmercury that bioaccumulates in aquatic life is created from mercury entering bodies of water with snowpack meltwater. To determine the importance of meltwater as a source of aquatic ... -
HPLC Analysis of Aliphatic Sulfonate Surfactants using Ion-Pair Detection
(Journal article; Peer reviewed, 2005)A method was developed for the analysis of a number of surfactants which contained no UV-chromophores, using RP-HPLC with Indirect Photometric Detection, IPD. Pyridinium salts such as N-methylpyridinium iodide, ... -
Hvilke tiltak kan gjøres for å forminske miljøpåvirkningene fra krom i forurenset jord?
(Bachelor thesis, 2021)Krom er et metall som er mye brukt i industrisammenheng. En finner blant krom annet i stålindustrien, farging av lær, blekk og malings produksjon samt impregnering av treverk. Disse industriene er bare noen eksempler på ... -
