Degree of polarization of light scattered from correlated surface and bulk disorders
(Journal article; Peer reviewed, 2023)Using a single scattering theory, we derive the expression of the degree of polarization of the light scattered from a layer exhibiting both surface and volume scattering. The expression puts forward the intimate connection ... -
Dehydration and Intercalation of CO2 in Fe-Fluorohectorites and Thermogravimetric Analysis of Cation Exchanged Fluorohectorites
(Master thesis, 2023)Karbonfangst i leire er blitt undersøkt som et resultat av økende CO2 i atmosfæren. CO2 kan absorberes i leire [1] og i denne oppgaven er denne absorpsjon undersøkt for prøvene Fe(III)-FHT og Fe(III)-FHT-sim, som er ... -
Delivery of Encapsulated Drugs to Cancer Cells and Tissue: The Impact of Ultrasound
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:57, Doctoral thesis, 2013)Encapsulated drugs have improved tumor to normal tissue uptake compared to free drugs, however, the concentration of drugs at the tumor site is still low and heterogeneous due to the tumor microenvironment which serves as ... -
Demonstrasjoner i optikk: Bruk av nyere teknologi for å synliggjøre optikk ved hjelp av demonstrasjoner
(Master thesis, 2012)Denne oppgaven prøver å svare på hvordan nyere teknologi kan brukes til å forbedre læringsutbyttet for studentene i optikk. Dette er en oppgave som både tar for seg teorien bak og gjennomføringen av tre demonstrasjoner og ... -
''Den figuren er irrelevant for meg'': En kvalitativ studie om elevers bruk av bilder og figurer i lærebøker i fysikk
(Master thesis, 2013)Oppgaven undersøker hvordan elever bruker metaforer, analogier og bilder i lærebøker i fysikk i egne læringsprosseser. Studien er bygd opp med intervju som datainnsamlingsmetode. Utvalget består av totalt åtte elever som ... -
Dense carbon-nanotube coating scaffolds stimulate osteogenic differentiation of mesenchymal stem cells
(Peer reviewed; Journal article, 2020)Carbon nanotubes (CNTs) have desirable mechanical properties for use as biomaterials in orthopedic and dental area such as bone- and tooth- substitutes. Here, we demonstrate that a glass surface densely coated with ... -
Density functional and classical simulations of liquid and glassy selenium
(Peer reviewed; Journal article, 2020)Molecular dynamics simulations of liquid and glassy selenium have been carried out using density functional (400–773 K, 600 atoms) and classical force field (290–500 K, 5488 atoms) methods. Structural features (structure ... -
Density functional simulations of a conductive bridging random access memory cell: Ag filament formation in amorphous GeS2
(Peer reviewed; Journal article, 2022)Density functional/molecular dynamics simulations have been performed to shed light on the drift of Ag atoms in an amorphous Ge S 2 solid-state electrolyte between Ag and Pt electrodes in the presence of a finite ... -
Density functional simulations of pressurized Mg-Zn and Al-Zn alloys
(Peer reviewed; Journal article, 2020)Binary Mg-Zn and Al-Zn alloys have been investigated theoretically under static isotropic pressure. The stable phases of these binaries on both initially hexagonal-close-packed (hcp) and face-centered-cubic (fcc) lattices ... -
Density Functional Theory Investigations of Surface Structure and Reactivity
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:93, Doctoral thesis, 2011)The Cr2O3(0001) surface is assumed to terminate by chromium atoms, chromyl groups, and oxygen atoms. This essentially models the industrial surface when subjected to different oxygen chemical potentials. The issue of high ... -
