21. Bandgap Engineering of Lead-Free Halide Double Perovskites
Sammanfattning : Lead-free halide double perovskites (HDPs, A2BIBIIIX6) with attractive optical and electronic features are regarded as one of the most promising alternatives to overcome the toxicity and stability issues of lead halide perovskites. They provide a wide range of possible combinations and rich substitutional chemistry with interesting properties for various optoelectronic devices. LÄS MER
22. Fill factor of organic solar cells and applications of dilute donor devices
Sammanfattning : Organic solar cells (OSCs) have attracted great attention due to their low cost, flexibility and solution-processibility. In recent years, the development of nonfullerene acceptors (NFAs) has truly promoted the efficiency of OSCs up to 19%, implying high potential for commercial applications. LÄS MER
23. Microbial DNA Sequencing in Environmental Studies
Sammanfattning : The field of microbial ecology has just entered a new era of rapid technological development and generation of big data. The high-throughput sequencing techniques presently available provide an opportunity to extensively inventorize the blueprints of life. LÄS MER
24. Social Media as Sociomaterial Service : On Practicing Public Service Innovation in Municipalities
Sammanfattning : Governments are in need to innovate public service. They struggle with complex societal problems, decreased citizen trust and the work of adapting to new demands related to how service should be delivered to fit contemporary living. LÄS MER
25. The genomic signatures of adaptive evolution in Populus
Sammanfattning : Understanding the genetic basis of adaptive evolution, and how natural selection has shaped patterns of polymorphism and divergence within and between species are enduring goals of evolutionary genetics. In this thesis, I used whole genome re-sequencing data to characterize the genomic signatures of natural selection along different evolutionary timescales in three Populus species: Populus tremula, P.
