1. Nanostructured carbon materials prepared by hole-mask colloidal lithography
Sammanfattning : Research and development of nanofabrication methods can be motivated both formanufacturing of commercially available products like micro electronic componentsand for development of model systems for fundamental and applied science. Thefabrication process developed during this work, hole-mask colloidal lithography(HCL), is primarily oriented towards the latter two, specifically for research in thefields of catalysis, nanoparticle plasmons, and bio- and fundamental physics.

2. Nanostructures of Graphite and Amorphous Carbon - Fabrication and Properties
Sammanfattning : Nanoscience is a well-established research area, which concerns properties and fabrication of objects with typical dimensions on the 1-100 nanometer length scale. A central issue has been the development of techniques for fabrication and characterization of nanometer sized objects, which have contributed considerably to progress in both practical applications and fundamental research.

3. Essays in Labor and Demographic Economics
Sammanfattning : Essay 1: (co-written with Olof Åslund) We study the impact of family size on intermediate and long-term outcomes using twin births as an exogenous source of varia¬tion in family size in an unusually rich dataset. Similar to recent studies, we find no evidence of a causal effect on long-term outcomes and show that not taking selection effects into account will likely overstate the effects. LÄS MER
4. Experiences of abandonment and anonymity among arthroplastic surgery patients in the perioperative period : some issues concerning communication, pain and suffering
Sammanfattning : Det övergripande syftet med avhandlingsarbetet är att illustrera och belysa upplevelsen av att vara patient med behov av ledprotes, avseende aspekterna kommunikation, smärtupplevelse, lidande och tillfredsställelse med vård och behandling. Under väntetiden för ledprotesoperation upplever deltagarna i studierna lidande i olika former, tillika att vården är otillgänglig och onåbar i ett ansiktslöst system (I). LÄS MER
