1. Bindningsstyrka mellan komposit och porslin för metallkeramik med förbehandling av olika reparationssystem
Kandidat-uppsats, Malmö universitet/Odontologiska fakulteten (OD)Sammanfattning : Syfte: Syftet med föreliggande in-vitro studie är att undersöka olika kompositbaserade reparationssystem och dess bindningsstyrka till porslin för metallkeramiska konstruktioner. Material och metod: Metallstavar tillverkades via CAD/CAM i CoCr (5.0x5.0x15. LÄS MER
2. Characterization of as prepared and exposed Perovskitesolar cells by microscopic and spectroscopic techniques
Master-uppsats, Högskolan Dalarna/Institutionen för information och teknikSammanfattning : Studying the microstructural features, optical, and electrical properties of the thin-filmperovskite solar cells (PSC) is the main objective of this thesis work. All the PSCs used in thisthesis work were prepared by spin coating assisted with gas quenching process and the samplesreceived from Interuniversity Microelectronics Centre (IMEC), Belgium. LÄS MER
3. Thermal Stability of Titanium and Niobium Stabilized Stainless Steel
Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : This master thesis examined the microstructure after heat treatments in stainless steel, two conventional stainless steel (304 and 316) and two novel high temperature stainless steel. These stainless steels are for the use in high temperature heat exchangers for extended temperature range. LÄS MER
4. Fabrication and Evaluation of Sb2Te3/PVDF Hybrid Thermoelectric Films
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Thermoelectric (TE) materials and devices have been extensively studied for harvesting waste heat energy. There is more interest to fabricate TE materials and devices at low cost and highly-efficient ways. LÄS MER
5. Records of environmental change and sedimentation processes over the last century in a Baltic coastal inlet
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The marine ecosystem in the Baltic Sea is affected by multiple stress factors, e.g. eutrophication and deoxygenation, overfishing and anthropogenic pollution. Here we evaluate the short-term trends of dissolved oxygen in bottom waters and changes in the primary productivity within a coastal inlet in the Baltic Sea. LÄS MER
