(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 1994)The nuclear and magnetic structures of ( Y 1 − x Ca x ) Ba 2 Fe 3 O 8 + δ with x=0.05, 0.10, and 0.20 have been investigated by neutron-powder diffraction at room temperature. The compound crystallizes with the symmetry ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2004)Two types of chemical-pressure effects on the Verwey-type transition in Ba Sm Fe 2 O 5 are studied, viz., ionic-size contractions at the Ba and Sm sites. Whereas the replacement of Sm by the smaller Eu and Gd atoms increases ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2004)Pressure effects on the charge-ordering (CO) transition have been investigated for an oxygen-deficient double-perovskite cobalt oxide, BaYCo 2 O 5.0 , through resistivity measurements using a piston-cylinder-type clamp ...
-
(Master thesis / Masteroppgave, 2006)Hensikten med denne oppgaven var å bestemme kvikksølv i jord i et nedbørfelt. Kvikksølv er en langtransportert luftforurensing som slippes ut fra antropogene så vel som naturlige kilder. Kvikksølv på elementær form blir ...
-
(Master thesis / Masteroppgave, 2007)The work is based on possible protonic transport in LaNb3O9. This ABO3–type perovskite is known to have large voids in the lattice due to many inherent A-site metal vacancies. Acceptor-doping of this material may facilitate ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2008)Zeolites with the CHA topology have been synthesized with Si/Al ratios ranging from 15 to 133. ICP-AES analysis shows that the Si/Al ratio in the material is close to linearly related to the Si/Al ratio in the reaction ...

(Master thesis / Masteroppgave, 2009)This work presents the first reported thin film deposition of α-Bi2O3 by ALD (Atomic Layer Deposition). In addition, thin films of Co3O4 and CoO are for the first time reported deposited by ALD from the respective novel ...
-
(Doctoral thesis / Doktoravhandling, 2009)Nøyaktige simuleringer av kjemiske og biologiske prosesser på molekylært nivå har lenge vært uoppnålig for en rekke molekylære systemer, og har nå blitt mulig for mange av disse systemene gjennom ny metodeutvikling av ...
-
(Doctoral thesis / Doktoravhandling, 2012)Fuel cells are expected to serve as a contribution to meet the demand for clean energy. High temperature fuel cells such as solid oxide fuel cells (SOFC) and proton ceramic fuel cells (PCFC) are developed for use as ...
-
(Doctoral thesis / Doktoravhandling, 2013)Facing the increasing environmental degradation locally and globally, the Chinese government sets mandatory goals of 10% reduction of SO2 emission and 20% reduction of energy intensity in its 11th Five-Year Plan period ...
-
(Master thesis / Masteroppgave, 2013)4-Substituted pyrido[1,2-e]purines as anticancer agents have the ability to intercalate with DNA molecules and display improved cytotoxic activities especially towards the resistant cancer cell lines (MCF7R). These compounds ...
-
(Doctoral thesis / Doktoravhandling, 2014)Gangliosides are sialic acid-containing glycosphingolipids expressed on all vertebrate cells. They are primarily positioned in the plasma membrane, with the ceramide part anchored in the membrane and the glycan part exposed ...
