Carbon Behaviour during Si Production
(Master thesis, 2013)First, the carbon content decreases with the increasing of silicon content in silicon phases. Second, the carbon content has no obvious trend in ferrosilicon phases. Third, the carbon element can be formed as silicon carbide ... -
Carbon Capture and Recovery by Molten Salts Electrochemistry
(Master thesis, 2022)To mitigate global warming and climate change, it is an urgent mission for us to reduce the amount of CO2 in the atmosphere. One of the viable solutions to this challenge may be to capture, and preferably, to recover CO2 ... -
Carbon Nanocones as Electrode Material in Lithium Ion Batteries
(Master thesis, 2011)A carbon powder containing carbon nanocones was used as an anode material in lithium ion batteries. The powder was also treated in different ways, chemically, with microwaves, and with heat. The carbon powder was tape ... -
Carbon-Coated Industrial-Grade Silicon as Potential Anode Material in Lithium-Ion Batteries
(Master thesis, 2021)Silisium (Si) er et lovende anodemateriale for neste generasjons litium-ione-batterier (LIB) grunnet dens evne til å reversibelt danne legeringer med høy litiumkonsentrasjon. Dette gir en ekstremt høy gravimetrisk kapasitet ... -
Carbon-Supported Nanostructured Core-Shell Catalysts for Low Temperature Fuel Cells
(Master thesis, 2015)The direct methanol fuel cell needs a catalyst with low overpotential and high current density for methanol oxidation to be commerically viable. The catalyst with highest performance at the moment is the PtRu-alloy catalyst, ... -
Case Hardening of Hardox 450 Steel for Increased Ballistic Strength
(Master thesis, 2011)AbstractSteel alloys are the material that is most used in protective constructions today. The reason is the overall good properties of steels, with its high strength and hardness, high ductility, high formability and ... -
Cathodic Protection of Steel-Aluminium Galvanic Couples for a New Generation of Lightweight Subsea Structures
(Master thesis, 2016)A new generation of lightweight subsea structures is planned for application in oil and gas production. Due to increasing weight of subsea installations, the use of aluminium as a structural material is of continuous ... -
Cation Nonstoichiometry of La2CoO4
(Master thesis, 2017)In this thesis, the cation nonstoichiometry and composition range of the La2CoO4 phase in the La-Co-O system were investigated and compared to earlier studies. There is a controversy over the cation nonstoichiometry of ... -
Ceramic matrix composites based on silicon carbide and carbon fibers
(Master thesis, 2019)Silisiumkarbid er velkjent for sine gode mekaniske og termiske egenskaper, som gir det et bredt spekter av industrielle anvendelser. SiC er imidlertid en sprø keramikk, og selv de minste sprekker kan vise seg katastrofale. ... -
Ceramic Thermal Barrier Coatings of Yttria Stabilized Zirconia Made by Spray Pyrolysis
(Master thesis, 2011)A thermal barrier coating (TBC) is used as thermal protection of metallic components exposed to hot gas streams in e.g. gas turbine engines. Due to a high thermal expansion coefficient, low thermal conductivity, chemical- ... -
