1. Development of a microfluidic device to study simultaneous crystallization in the LIBs recycling process
Master-uppsats, KTH/KemiteknikSammanfattning : Återvinning av litiumjonbatterier (LIB) är avgörande på grund av kritiska råmaterialreserver och miljöhänsyn vid kassering. Hydrometallurgisk LIB-återvinning, en framstående industriell teknik, står inför kostnadseffektivitets- och komplexitetsutmaningar. LÄS MER
2. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy
Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. LÄS MER
3. The Efficiency of PV Modules: Expectations vs. Reality : A study of the Degradation of Solar Panels in Sweden
Kandidat-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknikSammanfattning : Solar energy is one of the fastest growing green energy sources worldwide today. Thepioneer modules in Sweden have been in use for quite some time. The aim of the reporthas been to examine how PV modules in Sweden have degraded a few years into theirlife cycle. This was accomplished using data from PV modules installed no later than2014. LÄS MER
4. A study of optical and structural properties of spin-coated V2O3 thin films on sapphire substrates
Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiSammanfattning : Many transition metal oxides exhibit a Metal-Insulator Transition (MIT). This is an interesting phenomenon where the material undergoes a structural phase transition, and the electronic charge is redistributed in the crystal lattice. LÄS MER
5. Tribological behaviour of CVD diamondcoated tools during machining of highstrength aluminum alloy : Master thesis project on tribological behavior of super hard materials: chemicalvapor deposition diamond (CVD) coated cutting tools and polycrystalline diamond(PCD) cutting tools used in machining of high strength aluminium alloy
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : Machining of Aluminum can be complicated due to large amounts of adhesion and diffusion of the aluminum onto the cutting tool, causing effects such as built-up layers and built-up edges. This leads to poor surface finishes and can significantly affect the tool life. LÄS MER
