1. Large scale synthesis of polyesters with low amount of residual tin
Sammanfattning : Användningen av resorberbara polymerer för applikationer inom vävnadsersättning har ökat markant under de senaste decennierna. Tekniken innebär att celler får växa på ett polymert bärarmaterial och på så sätt återskapa skadad vävnad, och är ett lovande alternativ till många av de implantat som används idag. LÄS MER
2. Biodegradable Surfactants Containing Hydrolyzable Bonds
Sammanfattning : Surfactants with built-in weak bonds, so-called cleavable surfactants, are interesting candidates in the search for more environmentally friendly alternatives to traditional surfactants. The objective of this thesis was to perform a systematic study in which cleavable surfactants with different hydrolyzable bonds were compared with regard to physicochemical properties, and chemical and biological stability.

3. Konvertering av direkteluppvärmda flerbostadsområden-Beslutsunderlag och drivkrafter
Sammanfattning : The Swedish society is interested in reducing the use of electricity and especially electricity for heating purposes. For this purpose governmental subsidies have been introduced to support a change from electric heating to other types of heat supply systems. Owners of single and multifamily buildings can apply for the investment subsidy. LÄS MER

5. Stability Phenomena in Novel Electrode Materials for Lithium-ion Batteries
Sammanfattning : Li-ion batteries are not only a technology for the future, they are indeed already the technology of choice for today’s mobile phones, laptops and cordless power tools. Their ability to provide high energy densities inexpensively and in a way which conforms to modern environmental standards is constantly opening up new markets for these batteries. LÄS MER
