Nanomekanisk prøving av stål: Er mindre alltid sterkere?
(Master thesis, 2012)Gjennom dette arbeidet, er nanomekaniske kompresjonsegenskaper undersøkt for tre forskjellige materialer: To stål legeringer og et renjern. Pillarer av varierende størrelse, fra diameter 100nm til 2um, er fabrikkert ved ... -
Nanoscale friction and wear of a polymer coated with graphene
(Journal article; Peer reviewed, 2022)Friction and wear of polymers at the nanoscale is a challenging problem due to the complex viscoelastic properties and structure. Using molecular dynamics simulations, we investigate how a graphene sheet on top of the ... -
Nanoscale Simulations of Wear and Viscoelasticity of a Semi-Crystalline Polymer
(Peer reviewed; Journal article, 2020)We investigate the underlying tribological mechanisms and running-in process of a semi-crystalline polymer using molecular-dynamics simulations. We subject a slab of simulated polyvinyl alcohol to a sliding contact asperity ... -
Nanoscale Tribological Properties of Nanostructure Fe3Al and (Fe,Ti)3Al Compounds Fabricated by Spark Plasma Sintering Method
(Peer reviewed; Journal article, 2022)Nanostructured powder particles of Fe3Al and (Fe,Ti)3Al phases were produced using mechanical alloying. These intermetallic phases with a nearly complete density were consolidated by spark plasma sintering. The mechanical ... -
Nanoscale tribological simulations of a semi-crystalline polymer
(Doctoral theses at NTNU;2022:95, Doctoral thesis, 2022)Many of the objects surrounding us are made of polymers. Those polymers are often used for their tribological properties, for example, shoes with rubber soles or car tyres. Polymers materials become more and more presents, ... -
Nantes' and Oslo's urban water systems: Assessing benefits from water-energy nexus interventions.: Report number D1-2012-36
(Master thesis, 2012)In this thesis is investigated the water-energy nexus, the intricate relation that exists between water use in energy, and energy use in water. Indeed, literature review shows the importance of this relation and the necessity ... -
Natural Organic Matter Fouling in Low Pressure Membrane Filtration – Assessing Fouling Models by Advanced Particle/Aggregate Characterization
(Doctoral thesis at NTNU;, Doctoral thesis, 2015)To date, more and more traditional water treatment methods are replaced with membrane filtration owing to stringent quality requirements and limitations of such methods in coping with the future water quality requirements. ... -
Natural Superhydrophobic Surfaces: Nanostructures and Wetting States on Collembola Cuticles
(Doctoral theses at NTNU;2016:368, Doctoral thesis, 2016)Highly water repellent surfaces, known as superhydrophobic surfaces, have a range of potential applications including self-cleaning, drag reduction and air-retention. The first studies of the superhydrophobic effect was ... -
Near-Infrared Spectroscopic Method for Monitoring Water Content in Epoxy Resins and Fiber-Reinforced Composites
(Journal article; Peer reviewed, 2018)Monitoring water content and predicting the water-induced drop in strength of fiber-reinforced composites are of great importance for the oil and gas and marine industries. Fourier transform infrared (FTIR) spectroscopic ... -
Nedbørfelt som enkle, dynamiske system: Bruk av Kirchner (2009) si responsrutine i ein fordelt hydrologisk modell
(Master thesis, 2012)Mange mykje brukte hydrologiske modellar, til dømes HBV- modellen, er fysisk baserte; dei bygger på matematiske likningar som skildrar fysiske prosessar i ulike delar av det hydrologiske krinsløpet. Modellane inneheld ... -
Nedkjølingsalternativer i sykehjem med periodevis varmeproblematikk
(Bachelor thesis, 2020)I oppgaven undersøker vi ulike typer tiltak som finnes for nedkjøling av bygg og ser på hvilke løsninger som kan passe godt til et sykehjem. Fokuset ligger på kommunale sykehjem i Trøndelag uten eksisterende kjølesystem, ... -
Nedstrøms skråning av steinfyllingsdammer - modellforsøk av plastring under ulike strømningsforhold
(Master thesis, 2014)Formålet med denne masteroppgaven er å finne ut hvordan ulike strømningsforhold påvirker styrken av et plastret erosjonsdekke. Plastring er en metode å legge stein der steinene ligger stabilt og med god innbyrdes kontakt. ... -
