  1. 1. Nanoscale electron tomography and compositional analysis of Aerotaxy nanowires

    Författare :Axel Persson; -lup-obsolete; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transmission Electron Microscopy; Electron tomography; Nanowires; Aerotaxy;

    Sammanfattning : One common goal of sample analysis is to provide structural, compositional, or functional data in order to improve production parameters. One instrument specialized in such structural and compositional analysis with a high spatial resolution is the transmission electron microscope (TEM). LÄS MER

  2. 2. Transmission Electron Tomography and In-situ Analysis of Nanowires

    Författare :Axel Persson; NanoLund; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscopy TEM ; Electron tomography; Nanowires NWs ; Aerotaxy; In-situ;

    Sammanfattning : As semiconducting nanowires have promising applications for materials science, nanoelectronics and photovoltaic devices, absolute control of their structure, morphology and composition is a prerequisite for their functionality. Nanowires, grown through the vapor-liquid-solid (VLS) method, exhibit a complex relationship between their liquid seed particle and what properties, such as the aforementioned ones, the wire adopts in the end.

    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: Cholecystectomy is a common surgical procedure and incidental gallbladder cancer is a rare and unexpected finding at a cholecystectomy performed upon benign indications. Whether to perform routine or selective histopathology of the gallbladder specimen is still a subject for discussion. LÄS MER

  4. 4. Pedagogerna och demokratin. En rättssociologisk studie av pedagogers arbete med demokratiutveckling

    Författare :Lars Persson; Rättssociologiska institutionen; []

    Sammanfattning : The Swedish education system is governed by national steering documents, like the Education Act, curriculi and syllabuses. The democratic assignment is a central issue in these documents. The thesis aims to investigate how teachers handle this democratic assignment and how they are influenced by forces on different social levels. LÄS MER

  5. 5. Svensk brevkultur på 1800-talet : Språklig och kommunikationsetnografisk analys av en familjebrevväxling

    Sammanfattning : In this dissertation, I examine the correspondence of an upper middle-class family from the early part of the nineteenth century. My aim is to answer questions about correspondence and letter-writing as an everyday event and as a social activity. My principal theoretical framework has been ethnograpy of communication. LÄS MER
