11. Improving selectivity in protein extraction by subtle interactions and environmental changes
Sammanfattning : The challenges for efficient bioprocesses lie in developing and adapting further current technologies or in creating innovative separation technologies. The thesis is based on the studies on protein recovery from crude feedstocks by extraction in aqueous two-phase systems and detergent foam, respectively. LÄS MER
12. Clinical grade vitrification of human ovarian tissue for fertility preservation
Sammanfattning : Cryopreservation of human ovarian tissue is one approach to preserve fertility for women who can be predicted to undergo premature ovarian failure as a consequence of chemotherapy, radiotherapy or genetic disorders. It is the most suitable option for pre-pubertal girls and for many young women to store oocytes. LÄS MER
13. Shape Control Synthesis and Microstructure Studies of Metal Nanoparticles
Sammanfattning : Metal nanoparticles have been extensively studied in recent years due to their unique chemical, biological and physical properties. Gold (Au) and palladium (Pd) nanoparticles are two of the most popular materials because Au nanoparticles have a strong localized surface plasmon resonance effect and Pd nanoparticles have high hydrogen adsorption and chemical catalytic capacities.

14. Materials and interfaces for sustainable organic solar cells
Sammanfattning : Photovoltaics, the apparatus utilizing green solar power to generate electricity, is one of the efficient measures to the continuously increasing energy demand and exacerbated carbon emission of the human civilization. As a candidate with the potential of providing the cheapest and greenest form of electricity, organic solar cells (OSCs) received tremendous scientific interest, resulting in a significant power conversion efficiency (PCE) boosting to above 19% recently.

15. Molecular mechanisms of local anaesthetic action on voltage-gated ion channels
Sammanfattning : In this thesis I try to clarify some molecular mechanisms of local anaesthetic action on ion channels. The traditional view is that local anaesthetics eliminate action potentials by a direct block of Na channels. Other mechanisms, however, have been suggested. LÄS MER
