1. Sustainable food packaging based on polyhydroxyalkanoate
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. LÄS MER
2. Mathematical modeling and analysis of hot carrier solar cells
Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenSammanfattning : This thesis focuses on the analysis of a mathematical model of a nanowire based hot carrier solar cell. The relevance of the topic comes from the energy crisis society is facing today. Firstly, we discuss the basic principle of hot carrier solar cells and discuss several energy loss factors. LÄS MER
3. Sprickorna i Konstnärsförbundets styrelse
Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvårdSammanfattning : All oil paintings do degrade with time and a clear sign of this ageing is the cracks seen at the surface of the painting. Cracks can , however, also be hidden underneath the very surface and in fact extend all the way down to the very substrate. LÄS MER
4. The Influence of Pigment Additives on the Barrier Properties of Dispersion Coatings
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Att minska plastavfall och uppmuntra återvinning har fått hög prioritet i många affärsverksamheter och olika typer av regleringar implementeras för att minska den negativa påverkan av plastanvändningen. Papper och kartong består i huvudsak av cellulosa som har många egenskaper som är essentiella för en hållbar ekonomi (t.ex. LÄS MER
5. Optimisation of tribology of Alfa Laval separator screw gear systems
Master-uppsats, Luleå tekniska universitet/MaskinelementSammanfattning : Gears are machine elements essential for mechanical transmission. Wear of gear teeth can causechanges in their profile geometry, causing vibration, noise, and subsequent gear failure. In this thesisproject, a twin disc tribometer has been used to mimic the actual Alfa Laval separator screw gearsystems. LÄS MER
