1. Electrochemical characterization of materials for next generation polymer electrolyte fuel cells
Sammanfattning : Polymer electrolyte fuel cells occupy a key position in implementing the hydrogen economy on a global scale. However, assessments of cost, availability and sustainability of materials currently used to manufacture state-of-the-art fuel cell stacks have given cause for concern. LÄS MER
2. Synthesis, Characterisation and Properties of Biomimetic Biodegradable Polymers
Sammanfattning : The acceptance of blood contacting implants creating favorable conditions in vivo is decisively determined by their interaction with proteins that mediate inter cellular interactions with synthetic substrates. Adsorbed proteins can activate blood cascade systems like coagulation and complement that may result in serious blood clots, and/or immunological reactions. LÄS MER
3. Tailoring of Biomaterials using Ionic Interactions : Synthesis, Characterization and Application
Sammanfattning : The interactions between polymers and components of biological systems are an important area of interest within the fields of tissue engineering, polymer chemistry, medicine and biomaterials. In order to create such a biomimetic material, it must show the inherent ability to reproduce or elicit a biological function. LÄS MER
4. Proton-Conducting Polymers and Membranes for Fuel Cells-Preparation and Properties
Sammanfattning : The development of new materials for use in fuel cells is of importance for the probable replacement of the combustion engine by this technology in public vehicles in the future. The proton-conducting polymer electrolyte membrane is one of the main components in the fuel cell. LÄS MER
5. Combustion dynamics and melt dripping of ethylene-acrylate copolyer composites
Sammanfattning : The degradation and combustion of blends of ethylene-acryalte copolymer with calcium carbonate and silicone were studied by a combination of flammability tests, in-situ measurements and analytical experiments. Compounds of poly(ethylene-co-methacrylic acid) blended with precipitated calcium carbonate nanoparticles were prepared. LÄS MER
