Nanofiber NiMoO4/g-C3N4 Composite Electrode Materials for Redox Supercapacitor Applications
(Journal article; Peer reviewed, 2020)NiMoO4/g-C3N4 was fabricated by a hydrothermal method and used as an electrode material in a supercapacitor. The samples were characterized by XRD, FTIR, scanning electron microscopy (SEM) and transmission electron microscopy ... -
Nanoflow of Protons and Water in Polymer Electrolyte Membranes
(Master thesis, 2013)This master thesis studies the applicability of continuum mean-field theories such as the Poisson-Nernst-Planck equations and the Stokes equation. In particular, we investigate electro-osmotic flow of water and protons in ... -
Nanohinge-Induced Plasticity of Helical Carbon Nanotubes
(Journal article; Peer reviewed, 2013)Helical carbon nanotubes with intentionally incorporated non‐hexagonal defects have unexpectedly high toughness and plasticity, in addition to the well‐recognized extreme elasticity. The obtained toughness approaches 5000 ... -
Nanomanufacturing of dielectric metasurfaces supported by spectroscopic Mueller Matrix Ellipsometry
(Master thesis, 2022)Metamaterials are artificially structured composites. They can be used to modulate electromagnetic waves. The structural dimensions must be determined by being smaller than the working wavelength. Metasurfaces are multi- ... -
Nanomaterialer for kjemisk oksygenlagring
(Master thesis, 2014)Faserene nanokrystalline pulvere av heksagonal RMnO3, hvor R er Y eller Dy, ble syntetisert med en våt-kjemisk syntesemetode , og prøvene ble varmebehandlet ved forskjellige temperaturer for å oppnå varierende krystallit ... -
Nanomaterials - Toxic or Therapeutic?
(Master thesis, 2020)Nanomaterialer (NMer), slik som nedbrytningsprodukter av plast og konstruerte medikament leveringspartikler, både slippes ut i miljøet og administreres til mennesker i økende grad. Dette gjør at man stiller spørsmål ved ... -
Nanomaterials Enhanced Membranes for Carbon Capture
(Doctoral theses at NTNU;2020:253, Doctoral thesis, 2020)Alarming increase in global CO2 emissions has led to climate change. An acceleration in the development of CO2 capture technologies is therefore necessary to facilitate the large-scale implementation of Carbon Capture and ... -
