1. Vatten i faktaböcker : Kemiundervisning i förskolan
Uppsats för yrkesexamina på grundnivå, Karlstads universitet/Fakulteten för humaniora och samhällsvetenskap (from 2013)Sammanfattning : Syftet med studien är att göra en innehållsanalys av faktaböcker för barn sombeskriver vatten ur ett kemiskt perspektiv med fokus på vad faktaböckerna kanbidra med i förskolans kemiundervisning. Ett ämnesdidaktiskt tillvägagångssätthar använts där namngivning och sambandsintresse varit i fokus. LÄS MER
2. Techno-Economic Analysis of Dye Separation in Textile Recycling
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. LÄS MER
3. Gas Chromatographic Method Development for Analysis of Samples from a Carbon Capture Pilot Plant
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : In response to the escalating threat of climate change, carbon capture and storage have gained increasing attention as an important component in mitigating the global carbon dioxide emissions. Substantial research efforts have focused on enhancing the energy efficiency and availability of these technologies. LÄS MER
4. Microbial production of chemical building blocks from lignin
Master-uppsats, Lunds universitet/Teknisk mikrobiologiSammanfattning : Plastics, derived from fossil fuels, have raised considerable environmental concerns. This has prompted the search for sustainable and safer plastic precursors alternatives. One alternative explored in the present study is vanillin, a phenolic compound derived from lignin, an abundant and renewable natural polymer. LÄS MER
5. 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
