    Sammanfattning : Plastic pollution is one of the most pressing environmental issues in today’s world. Addressing this problem calls for the development of environmentally friendly alternatives that would reduce the amount of persistent plastic waste. LÄS MER

  3. 12. Technology in everyday life : a study of consumers and technology in a banking context

    Författare :Camilla Carlell; Alladi Venkatesh; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Consumers; Technology; Everyday Life; Methodological Triangulation.; Business Administration; företagsekonomi;

    Sammanfattning : Technology is increasingly making its presence felt in the lives of consumers. This disserta-tion focuses on how consumers use, relate to and make sense of technology. Through methodo-logical triangulation in the form of interviews, diaries, experiments and observations we hear individual consumers talk about their lives with technology. LÄS MER

    Sammanfattning : YTTERBY, a small village very close to Stockholm where I live, is the place in the world which has lent its name to the largest number of elements in the periodic table, namely four - YTTRIUM, YTTERBIUM, ERBIUM and TERBIUM. Three more lanthanide elements were discovered from the now empty quarry located in this village. LÄS MER

  5. 14. Understanding and Optimization of III-V nanowire growth in Aerotaxy

    Författare :Sudhakar Sivakumar; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor materials; Nanowires; Aerotaxy; Fysicumarkivet A:2021:Sivakumar;

    Sammanfattning : III-V semiconductor nanowires are high aspect ratio nanostructures with superior properties that can potentially enhance the functionality of next-generation opto-electronic devices. At present, the most reliable method for fabricating III-V semiconductor nanowires is the particle-assisted vapor-liquid-solid growth using a substrate-based growth process. LÄS MER

  7. 15. Near-Field Radiative Heat Transfer between Plasmonic Nanostructures

    Författare :Jin Dai; Min Yan; Philippe Ben-Abdallah; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fysik; Physics; Energy Technology; Energiteknik;

    Sammanfattning : Radiative heat transfer (RHT) due to coupled electromagnetic near field scan significantly exceed that dictated by Planck’s law. Understanding such phenomenon is not only of fundamental scientific interest, but also relevant to a broad range of applications especially connected to nanotechnologies. LÄS MER
