1. Early Stage Design of a Prefilmer at Siemens Energy : Numerical and Experimental Methodology
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : Design of atomizers for gas-turbine purposes are an important ordeal. The per-formance of the atomizer directly impacts the efficiency of the gas-turbine, andconsequently, the energy extracted from the turbine. Furthermore, the design ofthe atomizer can have an impact on reducing toxic emissions. LÄS MER
2. Phosphonium Ionic Liquids at Interfaces: NR studies of interfacial electro-responsiveness
Master-uppsats, KTH/KemiSammanfattning : Fosfoniumjonvätskor har tidigare studerats som potentiella nya avancerade smörjmedel på grund av sina unika fysikaliska egenskaper och fördelar jämfört med både traditionella smörjmedel och andra typer av jonvätskor. Dessa studier har uppvisat lovande resultat med avseende på reducering av nötning och friktion såväl som kontroll av dessa parametrar med en pålagd elektrisk potential. LÄS MER
3. Polymerization of isatin towards polymers for anion exchange membranes and gas separation applications
Master-uppsats, Lunds universitet/Kemiska institutionenSammanfattning : In a world where the problem of energy resources, pollution and all aspects related to these issues becomes more and more dominant, a greater commitment is needed in the search for solutions. The goal of this project is to make a contribution to the research and development of new materials to reduce the environmental impact in some fields. LÄS MER
4. Production of biocomposite materials from filamentous fungi grown on apple pomace
Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Managing and reducing food waste has increasingly become a global problem in later years, including food waste in the form of fruit pulp from the juice and beverage production industries. Another current urgent issue is the need for a replacement of fossil fuel-based plastics with more sustainable biopolymers. LÄS MER
5. The discoloration of polyethylene obtained from chemical separation of laminates: Investigating additives and other potential causes
Master-uppsats, Lunds universitet/FörpackningslogistikSammanfattning : PolyAl, the material composed of laminated polyethylene (PE) films and aluminum (Al) in carton, is a challenge in recycling due to the strong adhesion of the layers and the low value of the end products. In Europe, recent efforts to improve the circularity of carton packages include the chemical separation of PolyAl, in order to obtain higher values of the PE and Al separately. LÄS MER
