  2. 21. Characterization of Reaction Products in the Li-O2 Battery Using Photoelectron Spectroscopy

    Author : Reza Younesi; Kristina Edström; Patrik Johansson; Fredrik Björefors; Gabriel Veith; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Li-O2 Battery; Surface Characterization; Lithium-Air Battery; Photoelectron Spectroscopy; XPS; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : The rechargeable Li-O2 battery has attracted interest due to its high theoretical energy density (about 10 times better than today’s Li-ion batteries). In this PhD thesis the cycling instability of the Li-O2 battery has been studied. READ MORE

  4. 22. The Development of a European Fire Classification System for Building Products - Test Methods and Mathematical Modelling

    Author : Björn Sundström; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Byggnadsteknik; Teknik; Technological sciences; Brandteknik; Fire Protection Engineering; Conflame; Cone Tools; FDS; CFD; Duhamel?s integral; Fire Growth Rate; FIGRA; Euroclass; SBI; Single Burning Item; Cone Calorimeter; Room Corner Test; fire modelling; Reaction to fire; flashover;

    Abstract : The fire technical properties of products are determining factors for the initiation and growth of fires. Measurement of fire technical properties and the understanding of how they relate to real hazards are therefore important for fire safety. READ MORE

  5. 23. How do metamorphic fluids move through rocks? : An investigation of timescales, infiltration mechanisms and mineralogical controls

    Author : Barbara I. Kleine; Alasdair D. L. Skelton; John C. Schumacher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metamorphic fluid flow; fluid-rock interaction; fluid infiltration mechanisms; fluid flux rates; thermodynamic modeling; reaction front propagation; fluid flux calculation; Geology; geologi;

    Abstract : This thesis aims to provide a better understanding of the role of mountain building in the carbon cycle. The amount of CO2 released into the atmosphere due to metamorphic processes is largely unknown. READ MORE

  6. 24. Thin-Film Electrocatalysts for Polymer Electrolyte Fuel Cells - Activity, Durability and Proton Conduction

    Author : Björn Wickman; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nafion; thin film evaporation; PEMFC; platinum; titanium oxide; cathode; fuel cell; oxygen reduction reaction; electrocatalyst; proton conduction; model systems;

    Abstract : The polymer electrolyte membrane fuel cell (PEMFC) is a potential technology for future energy conversion in sustainable energy systems. By using hydrogen from renewable energy sources and oxygen from the air, the fuel cell produces electricity with water as the only exhaust. READ MORE

  7. 25. Modeling Antibody Aggregation in Downstream Processing

    Author : Frida Ojala; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antibody; Aggregation; Downstream processing; Size exclusion chromatography; Reversible reaction model; General rate model;

    Abstract : Antibodies are part of the immune system where their purpose is to recognize and neutralize foreign species such as viruses and bacteria, thus preventing and curing infections. The trend of using antibodies in the treatment of, for example, cancer is increasing. READ MORE
