Composition and morphology tuning during hydrothermal synthesis of SrxBa1−xNb2O6 tetragonal tungsten bronzes studied by in situ X-ray diffraction
(Journal article; Peer reviewed, 2019)Current interest in 1D ferroelectric materials calls for cheap, controllable, reproducible and environmentally friendly synthesis routes. Hydrothermal synthesis stands out as one of the most promising routes, but a thorough ... -
Composition and Structure Analysis of Hard Grey Scale (HGS) Formed on Cold Surfaces Exposed to Aluminium Production Off-gas
(Peer reviewed; Journal article, 2022)Hard grey scale (HGS) is a strongly adhering fouling material forming on solid surfaces impinged by off-gas generated in the pot cells of primary aluminium production plants. Even though associated maintenance costs have ... -
Composition and Surface Modifications of Silica Structures in Diatiom Frustules by Incorporation of Functional Oxides and Nitride Formation
(Master thesis, 2012)Renewable energy production featuring silicon photovoltaic solar cells are of considerable interest to reduce pollution and related environmental changes. Improvements in efficiency along with reductions in cost are key ... -
Composition Estimation in Dividing-Wall Columns Using Temperature Measurements
(Chapter, 2011)In this work, we propose a method to estimate the product compositions in a distillation column section based on a combination of a number of temperature measurements from different locations in ... -
Composition Methods for Stochastic Differential Equations
(Master thesis, 2022)I denne masteroppgaven undersøker vi splitte- og komposisjonsmetoder for å løse semi-lineære SDEer med additiv støy, hvor driftleddet tilfredsstiller en global ensidig Lipschitzbetingelse, er tillatt polynomisk vekst og ... -
Composition of gut microbiota of children and adolescents with perinatal HIV infection taking antiretroviral therapy in Zimbabwe
(Journal article; Peer reviewed, 2019)Background Human immunodeficiency virus (HIV) infection causes impairment of the gastrointestinal barrier, with substantial depletion of CD4+ T cells in the gut. Antiretroviral therapy (ART) restores CD4+ counts and may ... -
Composition of New Features into a Wireless Nurse Call System
(Master thesis, 2011)Healthcare needs are evolving constantly, some of these needs are already being covered by current technology but some are still not. This thesis offers a critical review of former work relating to ICT and hospitals, ... -
Composition operators and embedding theorems for some function spaces of Dirichlet series
(Journal article; Peer reviewed, 2019)We observe that local embedding problems for certain Hardy and Bergman spaces of Dirichlet series are equivalent to boundedness of a class of composition operators. Following this, we perform a careful study of such ... -

Composition operators on Bohr-Bergman spaces of Dirichlet series
(Journal article; Peer reviewed, 2016)For α ∈ R, let Dα denote the scale of Hilbert spaces consisting of Dirichlet series f(s) = P∞ n=1 ann −s that satisfy P∞ n=1 |an| 2/[d(n)]α < ∞. The Gordon–Hedenmalm Theorem on composition operators for H 2 = D0 is extended ... -
Composition operators on the Hardy space of Dirichlet series
(Master thesis, 2020)Vi betrakter Dirichlet-rekker med kvadratisk summerbare koeffisienter som utgjør Hardy-rommet $\mathscr{H}^2$. Formålet med denne avhandlingen er å studere komposisjonsoperatorer på dette rommet. Eksempelvis beviser vi et ... -

Composition-Dependent Morphology, Structure, and Catalytical Performance of Nickel–Iron Layered Double Hydroxide as Highly-Efficient and Stable Anode Catalyst in Anion Exchange Membrane Water Electrolysis
(Peer reviewed; Journal article, 2022)Water splitting is an environmentally friendly strategy to produce hydrogen but is limited by the oxygen evolution reaction (OER). Therefore, there is an urgent need to develop highly efficient electrocatalysts. Here, NiFe ... -
Compositional and structural properties of pulsed laser-deposited ZnS:Cr films
(Journal article; Peer reviewed, 2016)We present the properties of Cr-doped zinc sulfide (ZnS:Cr) films deposited on Si(100) by pulsed laser deposition. The films are studied for solar cell applications, and to obtain a high absorption, a high Cr content ... -
