11. Investigating the role of water in the protein dynamic transition
University essay from Stockholms universitet/FysikumAbstract : Proteins undergo a dynamic transition at approximately 220 K, also called protein ’glass’ transition, below which temperature proteins lose their conformational flexibility and become biologically inactive. The protein dynamic transition has been observed for several proteins utilizing different techniques, such as inelastic neutron scattering, infrared spectroscopy and X-ray crystallography. READ MORE

12. Creating nanopatterned polymer films for use in light-emitting electrochemical cells
University essay from Umeå universitet/Institutionen för fysikAbstract : Thermal nanoimprint lithography (T-NIL) is a cheap and fast technique to produce nanopatterns in polymeric materials. It creates these patterns by pressing a stamp down into a polymer film that has been heated above its glass transition temperature. READ MORE

13. Thermoplastic composites in aerosructure industries : An evaluation report
University essay from KTH/MaterialvetenskapAbstract : There has been a high development of advanced composites with matrix systems of thermoset polymers in the aerostructure industry, but these thermosets can cause problems. Therefore, the aim of this project is to evaluate matrix systems made of thermoplastics, which has been done by theoretical studies. READ MORE

15. A study of poly(vinyl alcohol) as a solid polymer electrolyte for lithium-ion batteries
University essay from Uppsala universitet/StrukturkemiAbstract : The use of solid polymer electrolytes in lithium-ion batteries has the advantage in terms of safety and processability, however they often lack in terms of performance. This is of major concern in applications where high current densities or rapidly changing currents are important. READ MORE
