Self-assembled superstructures of magnetic nanoparticles: advanced nanofabrication and enhanced mechanical properties
Håkonsen, Verner (Doctoral theses at NTNU;2020:271, Doctoral thesis, 2020)Artificial materials composed of self-assembled magnetic nanoparticles (i.e. magnetic superstructures) have attracted immense scientific interest in the past two decades due to their extraordinary collective behavior. An ... -
Spinel oxide protective coatings for solid oxide fuel cell interconnects
Nguyen, Thong Xuan (Master thesis, 2013)Metallic interconnects in solid oxide fuel cells are dependent on protective coatings to ensure adequate application lifetime. Of the many coatings investigated, spinel composition coatings display the most promising ... -
Stability and compatibility of fuel cells based on proton conducting materials
Bjørnevik, Inger Marie (Master thesis, 2011)Stability and compatibility of the proton conducting electrolyte material La6WO12 with the potential cathode materials LaCoO3 and La2NiO4 were investigated by means of solid-solid diffusion couples. Reactivity studies were ... -
Stress Corrosion Cracking of Carbon Steel in Amine Solution
Sigurd Johannes Gaut (Master thesis, 2019)I denne oppgaven undersøkes muligheten for spenningskorrosjon og andre sprøbruddsmekanismer i et S235JR stål i en løsning av 30% monoetanolamin. Strekktesting ved lav tøyningshastighet ble foretatt med to og to prøver i ... -
Syntetisering av NMC111-katoder til Litium-ionbatterier
Bryntesen, Silje Nornes (Master thesis, 2019)Å oppnå Li-ion batterier (LIBer) med høy energy tetthet, avhenger blandt annet av pulveregenskapene til det aktive katodemateriale. Det er under syntesen av dette pulveret de ekstrinsike og intrinsike egenskapene blir ... -
The Potential of Functionalized Ceramic Particles in Coatings for Improved Scratch Resistance
Rusu, Caterina Lesaint; Brodin, Malin; Hausvik, Tor Inge; Hindersland, Leif Kåre; Chinga-Carrasco, Gary; Einarsrud, Mari-Ann; Lein, Hilde Lea (Journal article; Peer reviewed, 2018)The top layer of a typical high pressure floor laminate (HPL) consists of a melamine formaldehyde (MF) impregnated special wear layer (overlay) with alumina particles. This top layer plays a crucial role in determining the ... -
Thermal and mechanical properties of crack-designed thick lanthanum zirconate coatings
Weber, Sophie Beatrice; Lein, Hilde Lea; Grande, Tor; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2014)Vertical cracks are beneficial in thermal barrier coatings due to enhanced thermo-mechanical compliance. Accordingly, an aqueous nitrate based precursor solution was atomized on stainless steel substrates by spray pyrolysis ... -
