  1. 21. Bandgap Engineering of Lead-Free Halide Double Perovskites

    Författare :Fuxiang Ji; Feng Gao; Feng Wang; Niclas Solin; David Mitzi; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lead-free halide double perovskites; Metal doping alloying; Bandgap engineering; Atomic-level structure; Thermochromism;

    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

  3. 22. Fill factor of organic solar cells and applications of dilute donor devices

    Författare :Nannan Yao; Fengling Zhang; Jonas Bergqvist; Jan van Stam; Weimin Chen; Julia W. P. Hsu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    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

    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

  5. 24. Social Media as Sociomaterial Service : On Practicing Public Service Innovation in Municipalities

    Författare :Livia Norström; Martin Gellerstedt; Ulrika Lundh Snis; Iréne Bernhard; Anna Ståhlbröst; Högskolan Väst; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social media; Municipalities; Communicators; E-government; Participatory government; Engaged scholarship; Service innovation; Practice perspective; Sociomateriality; Work Integrated Learning; Arbetsintegrerat lärande; Informatik; Informatics;

    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

  7. 25. The genomic signatures of adaptive evolution in Populus

    Författare :Jing Wang; Pär Ingvarsson; Barbara Mable; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Populus; adaptive evolution; natural selection; genomic diversity and divergence; recombination; Next-generation sequencing; local adaptation;

    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.
