Is sustainable production of the MOFs MIL-101 and MOF-5 possible without reducing the hydrogen storage capacity of the material?
(Bachelor thesis, 2022)Metal organic frameworks (MOFs) er noen av de mest lovende porøse materialene når det kommer til hydrogenlagring, hvorav to av de mest lovende er MIL-101 og MOF-5. De konvensjonelle syntesene av de to MOFene involverer ... -
Is the doped MoS2 basal plane an efficient hydrogen evolution catalyst? Calculations of voltage-dependent activation energy
(Peer reviewed; Journal article, 2023)Transition metal dichalcogenides are cheap and earth-abundant candidates for the replacement of precious metals as catalyst materials. Experimental measurements of the hydrogen evolution reaction (HER), for example, have ... -
Is the rate of metabolic ageing and survival determined by basal metabolic rate in the zebra finch?
(Journal article; Peer reviewed, 2014-09-29)The relationship between energy metabolism and ageing is of great interest because aerobic metabolism is the primary source of reactive oxygen species which is believed to be of major importance in the ageing process. We ... -
Is there genetic variation in the response to competition intensity in juvenile brown trout Salmo trutta?
(Journal article; Peer reviewed, 2011)Effects of intraspecific competition intensities on the relative performance (growth and movement) of juvenile brown trout Salmo trutta originating from nine different families were tested in tank experiments and in ... -
Is there plasticity in developmental instability? The effect of daily thermal fluctuations in an ectotherm
(Journal article; Peer reviewed, 2017)Diversified bet‐hedging (DBH) by production of within‐genotype phenotypic variance may evolve to maximize fitness in stochastic environments. Bet‐hedging is generally associated with parental effects, but phenotypic variation ... -
Is Thienopyrimidine a Suitable Scaffold for HER2 Tyrosine Kinase Inhibitors?
(Bachelor thesis, 2022)HER2-positiv brystkreft er en kreftform med økt uttrykk av HER2-reseptoren, som fører til ukontrollert cellevekst og celledeling. En behandlingsmetode for denne typen kreft er hemming av det intracellulære kinasedomenet ... -
Isbjørnens effekt på fugl i et arktisk klima i endring - Sluttrapport for Svalbards miljøvernfond
(NINA Rapport;1163, Research report, 2015)Arktis blir stadig varmere og utbredelsen av havis blir mindre. Det forandrer leveområdet til de mange artene som er avhengige av havis. Isbjørnen er avhengig av havis for å jakte på sel, og økende lengde på den isfrie ... -
Isolation and Characterization of Oil-Soluble Calcium Naphthenates in North Sea Heavy Crude Oil
(Master thesis, 2014)Naphthenic acids are a diverse group of saturated mono- and polycyclic carboxylic acids that may account for as much as 10-12 weight % of crude oil. During production at several newer oil fields, there have been discoveries ... -

Isolation and genome sequencing of four Arctic marine Psychrobacter strains exhibiting multicopper oxidase activity
(Journal article; Peer reviewed, 2016)Background Marine cold-temperature environments are an invaluable source of psychrophilic microbial life for new biodiscoveries. An Arctic marine bacterial strain collection was established consisting of 1448 individual ... -
Isolation and genotypic characterization of different yeast strains from Nepalese mixed culture (Murcha)
(Master thesis, 2017)14 different yeast strains were isolated from the Nepalese yeast cakes (murcha) of six different places varying in geographical condition. The isolation was entirely random based on the morphologies of the colonies, were ... -
