Characterization and recovery of rare earth elements from electronic scrap
(Master thesis, 2012)The rare earth elements are a group of 17 elements consisting of the lantahnide series, scandium and yttrium. The application with the largest rare earth consumption is the permanent rare earth magnets. The neodymium-iron-boron ... -
Comparison Between Microstructure Parameters and Electrochemical Performance of Ni-CGO Anodes in SOFC Subjected to Redox-Cycling
(Master thesis, 2011)The aim of this thesis was to create an understanding between the electrochemical performance of a porous Ni-CGO anode used in SOFC, and its microstructural parameters when subjected to redox-cycling. The anode samples ... -
Corrosion of Thermally Sprayed Aluminum in Flowing Seawater
(Master thesis, 2012)Raw sea water can be pumped into subsea wells where pressure drops have occurred to increase the pressure again and thereby the production rate. Thermally sprayed aluminum (TSA) is considered as internal corrosion protection ... -
Effect of marine environment on the tribology performance of materials used in lubricated rotating parts of offshore wind turbines
(Master thesis, 2012)The use of offshore wind turbines as a source of renewable energy is promising. However, many challenges have to be solved before they will be cost effective. The operation time, without any maintenance required, is desired ... -
Electro-oxidation of ethanol at Pt electrodes with the use of a Dynamic Electrochemical Impedance Spectroscopy (DEIS) technique
(Master thesis, 2012)Electro-oxidation of ethanol on smooth platinum surfaces was studied in thetemperature range 21C to 140C for 0.2 M ethanol in 0.5 M sulphuric acid.This was done by use of cyclic voltammetry and electrochemical impedances ... -
Investigation of metallic bipolar plates for PEM fuel cells
(Master thesis, 2011)High cost and a short lifetime are the two main reasons why the PEM fuel cell is yet to be commercialized. The bipolar plate in a PEM fuel cell is alone responsible for about 45% of the cost and 85% of the total weight of ... -
Organic binder as a substitute for bentonite in ilmenite pelletization
(Master thesis, 2012)TiZir Titanium & Iron produces high titania slag and high purity pig iron from ilmenite in Tyssedal. The ilmenite is pelletized before smelting. Bentonite is added to the ilmenite concentrate as a binder to give the pellets ... -
Photoelectrochemical Hydrogen Production
(Master thesis, 2012)The possibilities for using CaNb2O6 as a photocatalyst in direct water splitting have been evaluated by investigating the electronic structure of the material. In addition the oxide was doped with nitrogen in order to ... -
Pitting and Crevice Corrosion of Stainless Steel under Offshore Conditions
(Master thesis, 2012)AISI 316/316L has traditionally been used in offshore topside environments when operating under low temperatures. It has been observed that the AISI 316/316L piping suffer from severe attacks of pitting and crevice corrosion ... -
Process- and Alloy Development of Recyclable Aluminium Alloys: Recovery and Recrystallization Behavior of a Selection of AlMn-model Alloys
(Master thesis, 2011)A study of the effect of various amounts of manganese in solid solution on the recovery and recrystallization behavior of an AlMn-alloy, for different annealing conditions after different degrees of deformation (cold ... -
Wet Chemical Synthesis of Materials for Intermediate Band Solar Cells
(Master thesis, 2011)The economical feasibility of commercial, single-junction solar cells is limited by high costs and limited efficiencies. New solar cell concepts and materials are sought to decrease the production costs and increase the ...
