1. Polymeric Microcavities for Dye Lasers and Wavefront Shapers
Abstract : Over the last few years, the available computing power allows us to have a deeper insight into photonics components than we ever had before. In this thesis we use the finite element method (FEM) to explore the behavior of the waves in 2D planar microcavities. READ MORE

2. Work in voluntary welfare organizations : A sociological study of voluntary welfare organizations in Sweden
Abstract : Since Sweden has one of the most comprehensive welfare states, the role of voluntary organizations active in the field of welfare is often neglected. The unique Swedish nonprofit sector is characterized by 1) the tradition of popular mass movements in which members are central and the real owners of the organization, 2) large membership and volunteering, but low employment levels, 3) dominance in the fields of culture and recreation, but the relative marginalization in welfare.

3. Carbon Recovery in A Dual Fluidized Bed Gasifier
Abstract : As the concept of a circular economy gains acceptance and awareness of climate change and its disastrous consequences increases, the ways in which we produce the carbon-based goods upon which so much of our economy depends need to change. Society must end its reliance on fossil carbon resources and shift to renewable sources that enable the establishment of a carbon cycle. READ MORE

4. Strategies for Complete Recovery of Carbon in Dual Fluidized Bed Gasifiers
Abstract : To establish a circular economy and curtail our dependency on fossil resources, technologies are needed to extract carbon from biomass and plastic waste. Dual fluidized bed (DFB) gasification is a carbon-extracting technology that offers flexibility in terms of its inputs, outputs, design, and operational conditions. READ MORE

5. On the Environmental Relevance of Platinum Group Elements
Abstract : It has recently been demonstrated that platinum group elements (PGE) are released from automobile catalysts into the environment, raising concern over ecological and human health risks. However, there is still a lack of knowledge regarding the dispersion and transformation of PGE in the environment and it is therefore difficult to assess potential risks. READ MORE
