-
(Master thesis / Masteroppgave, 2015)In aquaculture today, vaccination of farmed fish is successfully providing protection against many of the most common pathogens. However, while vaccines are most commonly given as a single injection, this is not the ideal ...

Zeolite morphology and catalyst performance: Conversion of methanol to hydrocarbons over offretite (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The synthesis, characterization and catalytic performance of offretite with four distinct crystal morphologies (oval, hexagonal, broccoli-like, and spherical) are presented. As a member of the ABC-6 family of zeolite ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)This contribution clarifies the overoxidation-preventing key step in the methane-to-methanol (MTM) conversion over copper mordenite zeolites. We followed the methane-to-methanol conversion over copper mordenite zeolites ...
-
(Research report / Forskningsrapport, 2016)Modern cloud applications consist of software components deployed on multiple virtual machines. Deploying such applications is error prone and requires detailed system expertise. The deployment optimization problem is about ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)A matrix with a nonzero nonnegative vector in its null space is called central . We study classes of central matrices having zero column sums. The study is motivated by an engineering application concerning induction ...

A Zero-Coupon Bond based Spread Option : An Application of the Heath-Jarrow-Morton ModelRestricted Access (Master thesis / Masteroppgave, 2013)In this thesis we derive the price of a spread option based on two zero-coupon bonds. The two bonds will represent di erent nancial markets, and the HJM framework is used as the model for the underlying forward rates. We ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)A matrix of the form A = BBT where B is nonnegative is called completely positive (CP). Berman and Xu (2005) investigated a subclass of CP-matrices, called f0, 1g-completely positive matrices. We introduce a related concept ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Zn complexes of Schiff base ligands derived from 2,2'‐diaminobiphenyls and salicylaldehyde derivatives were synthesized and characterized by NMR and single‐crystal X‐ray diffraction analysis. The detailed NMR studies suggest ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)By combining results from positron annihilation and photoluminescence spectroscopy with data from Hall effect measurements, the characteristic deep level emission centered at ∼1.75 eV and exhibiting an activation energy ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)The aluminum–zinc-vacancy (AlZn−VZn) complex is identified as one of the dominant defects in Al-containing n-type ZnO after electron irradiation at room temperature with energies above 0.8 MeV. The complex is energetically ...

-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Mineral inclusions are common and have been widely used to investigate complex geological history. When a rock undergoes cooling and decompression after the entrapment of an inclusion into a host mineral, residual pressure ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Ion implantation of Zn substituting elements in ZnO has been shown to result in a dramatic Li depletion of several microns in hydrothermally grown ZnO. This has been ascribed to a burst of mobile Zn interstials. In this ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The influence of annealing on the microstructure and electrical properties of undoped polycrystalline ZnSb samples has been investigated by different experimental techniques. In situ XRD in an argon at- mosphere showed ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Carbapenem-resistant Gram-negative pathogens are a critical public health threat and there is an urgent need for new treatments. Carbapenemases (β-lactamases able to inactivate carbapenems) have been identified in both ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The ZnCr2O4/ZnO materials system has a wide range of potential applications, for example, as a photocatalytic material for waste-water treatment and gas sensing. In this study, probe-corrected high-resolution scanning ...
-
(Doctoral thesis / Doktoravhandling, 2011)Zinc oxide (ZnO) and its ternary alloys have high potential to compete with III-V nitrides for optoelectronic applications. Furthermore, oxide semiconductors receive considerable attention due to their low cost of fabrication, ...
-
(Master thesis / Masteroppgave, 2011)Zinc oxide has attracted a great deal of interest in recent years with a view to potential photovoltaic applications, particularly as a material for transparent conducting electrodes. The material's abundance and low cost ...
