Zero strain cathode
(Master thesis, 2023)For å realisere fast fase-batterier som en levedyktig, markedsklar teknologi må problemer med tap av kontakt mellom batterikomponenter løses, da det medfører tap av kapasitet som til slutt ødelegger batteriet. En av ... -
Zinc-rich coatings for improved corrosion resistance of extruded aluminium heat-exchange tubing in acidified chloride solution
(Doctoral theses at NTNU;2017:294, Doctoral thesis, 2017)Thin walled heat exchanger Al alloy tubes, with solid-solution Zn-rich surface, are widely used by the automotive industry and are considered by the heat, ventilation, air-conditioning and refrigeration market. This work ... -
Zirconium hydrogen phosphate as an additive in electrocatalytic layers for the oxygen evolution reaction in PEM water electrolysis
(Journal article, 2015)For reasons of electrode integrity and durability it is desirable to add zirconium hydrogen phosphate to electrocatalytic layers in PEM water electrolysis. Common synthesis methods are frequently associated with an ... -
Zr-Based Metallic Glasses as Biomaterials: Design, Production and Characterization
(Doctoral theses at NTNU;2019:2, Doctoral thesis, 2019)Metallic Glasses (MGs) have a unique non-crystalline structure which is the main reason for their extraordinary properties, e.g. high hardness, good wear resistance, high corrosion resistance, as well as the ability to be ... -
α-Mg primary phase formation and dendritic morphology transition in solidification of a Mg-Nd-Gd-Zn-Zr casting alloy
(Journal article; Peer reviewed, 2016)Microstructure evolution in the commercial Mg-Nd-Gd-Zn-Zr alloy Elektron 21, solidified under nearly isothermal conditions, has been studied via in-situ X-ray radiography. For cooling rates View the MathML source≤0.075 ... -
β- and δ-Al-Fe-Si intermetallic phase, their intergrowth and polytype formation
(Journal article; Peer reviewed, 2019)Crystal structure characteristics of coexisting β and δ phase were investigated in a purely intermetallic Al-Fe-Si alloy and in plate-shaped intermetallic particles formed in a model secondary Al7.1Si1.2Fe0.3Mn alloy. The ...
