1. Geometallurgical study of historical tailings from the Yxsjöberg tungsten mine in Sweden : Characterization and reprocessing options
Sammanfattning : Tungsten (W) is listed among the European Union (EU) critical raw materials (CRMs) for its supply risk and economic importance. Primarily, tungsten is produced from scheelite and wolframite mineral ores with 0.08-1.5% tungsten trioxide (WO3) grade. LÄS MER
2. Particle Characterization in the Exhaust Devices of Direct Injection Engines
Sammanfattning : Minimizing pollutants are of utmost importance to ensure sustainability in transportation. Particle emissions from internal combustion engines are especially harmful to human health, while also contributing to global warming. LÄS MER
3. Particle Coating in a Wurster Type Bed
Sammanfattning : The Wurster bed process is frequently used for film coating. In the Wurster bed, particles circulate in the equipment and are sprayed with a liquid which forms a coating when dry. The procedure is repeated until the desired characteristics of the coating layer are obtained. LÄS MER
4. Statistical methods in single particle fluorescence microscopy
Sammanfattning : The aim of this thesis is stochastic modeling and statistical inference in single particle fluorescence microscopy related to the experimental observation of randomly moving particles. A central theme is the use of single particle microscopy for estimation of absolute concentration of nanoparticles performing Brownian motion. LÄS MER
5. Concentration measurements in single particle microscopy
Sammanfattning : The topic of this thesis is the introduction of two novel methods for using single particle microscopy as a tool for absolute number concentration measurements of Brownian particles. The key idea of both methods is that in order to estimate number concentration, the size of the (three-dimensional) particle detection region has to be estimated. LÄS MER
