In this work, we have used both plain titania nanotubes, TNTs, and their reduced black analogues, bTNTs, that bear metallic conductivity (prepared by solid state reaction of TNTs with CaH2 at 500 °C for 2 h), as catalyst supports for the oxygen evolution reaction (OER). Ir was subsequently been...

Denne anvisningen inneholder tabeller og kart med klimadata for landets kommuner for normalperioden 1991–2020. Klimadataene gir grunnlag for termisk dimensjonering og frostsikring av konstruksjoner mot grunnen som fundamenter for oppvarmede og uoppvarmede bygninger, ledninger og veier slik at krav i...

Digitalisering har gjort norsk olje- og gassindustri mer effektiv, mer fleksibel og bedre rustet for en framtid med lavere utslipp og høyere krav til effektiv drift. Samtidig har digitaliseringen gjort industrien mer avhengig av komplekse IT- og kontrollsystemer. Det vil si systemer som kan bli mål...

Electric heating in buildings is the dimensioning factor of the Norwegian power grid and is expected to become increasingly important globally with electrification of the building sector. Due to the lack of sub-meters, the full demand side flexibility potential of buildings remains unknown. While...

We present two electrically-driven MEMS-tunable metasurfaces for dynamic vortex beam generation: a single-layer optical metasurface for mode-switchable vortex lasers, and a double-layer metasurface for dynamic vortex wave plates, showcasing high mode purity and fast response at 1030 nm wavelength....

This conference paper explores hybrid battery energy storage systems (HBESS) through a simulation-based analysis, combining a commercial nickel manganese cobalt oxide cell with a next-generation cell and evaluating their performance under a realistic application scenario. The study employs physics...

Accurate half-cell open-circuit potential functions are essential for physics-based battery models but are traditionally obtained through invasive and time-consuming procedures. This work introduces a systematic procedure that reconstructs half-cell potentials from full-cell voltage data...

Geometrien til asimut-propellar er i dag tidkrevjande å inkludere i CFD berekningar. Målet med dette prosjektet var å bli i stand til å optimere og dokumentere energieffektiviteten til skip med asimutpropellar på ein effektiv og industrielt anvendbarmåte. Denne rapporten oppsummera korleis vi har...

Cystometry is a urodynamic investigation used to examine the pressure-volume relationship during bladder filling. In clinical practice, cystometry is typically performed with water or air-filled catheters connected to an external transducer. These catheters, which are primarily suited for short...

Life cycle assessment (LCA) enables the quantification of how use, reuse, and recycling methods affect the environmental footprint of gear types from the aquaculture industry. Several Norwegian actors have recently proposed new solutions for the end-of-life treatment of used aquaculture equipment...

Magnesium-based hydrogen storage materials are promising candidates for hydrogen storage due to their high storage density and environmentally friendly properties. However, the high dehydrogenation enthalpy change (approximately 75 kJ/mol H₂) and high dehydrogenation temperature (573 K at 0.1 MPa...

Plastic components are widely used in fisheries and aquaculture (F&A) systems due to their lightweight, durability, cost efficiency, and resistance to seawater corrosion. Common applications include solid blocks, filaments, ropes, nets, and films. However, plastics in F&A contribute significantly to...

As climate change raises temperatures, projecting future building energy demand is crucial for adaptation, mitigation, and resilient infrastructure and energy systems. This is intensified by Europe’s ageing population, including Norway, where more elderly residents will increase demand for elderly...

The integration of high-energy lithium-ion batteries (LIBs) as energy storage solutions is increasing in the building sector (e.g., residential, schools, offices, commercial and industrial buildings). This increases the fire load, raising fire safety concerns, including characteristic fire behaviour...

This chapter focuses on issues of justice in sustainability transitions. Although there is an increasing focus in academia, policymaking and practice on the importance making sustainability transitions not only environmentally and economically sustainable, but also just and fair so that costs and...

Denne rapporten utreder konseptet FiskInfoPlattformen: en digital plattform for fangst og bærekraftsrapportering basert på operasjonell datafangst under fiske. Arbeidet tar utgangspunkt i grunnstammen for databaserte fiskeritjenester som ble etablert i FHF prosjekt 901803 og utvider dette med...

Oppdraget med å videreutvikle indikatorer for universell utforming for kollektivtransport på vei dokumenteres i denne rapporten, samt i presentasjon for lysark og revisjon av regneark som benyttes for registrering av holdeplasser. Oppgaven har bestått i å videreutvikle indikatorsettet, forbedre...

Repurposing the existing natural gas pipeline infrastructure for hydrogen applications poses safety concerns regarding hydrogen embrittlement. Pipeline weldments are particularly considered as vulnerable sites for hydrogen-induced degradation effects. To this end, this study evaluates the...
