  1. 11. New laser-based techniques for nanometre lithography and microscopy

    Författare :Lars Malmqvist; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microscopy; near-field; frequency doubling; optical trapping; laser plasma; Atomic and molecular physics; low debris; Fysicumarkivet A:1996:Malmqvist; X-ray lithography; Atom- och molekylärfysik;

    Sammanfattning : This thesis describes the development of new laser-based techniques for nanometre lithography and microscopy. The potential of a non-intrusive scanned near-field optical microscope (SNOM) has been investigated. The probe consists of an optically trapped microscopic particle which is scanned in proximity to the object to be studied. LÄS MER

  2. 12. Computer assisted video microscopy : in characterization of capillary ensembles

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Claes Asker; Linköpings universitet.; Linköpings universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; computer assisted video microscopy; capillary loops; capillary ensembles; skin microcirculation; triangulation; nearest neighbour; MEDICINE; MEDICIN;

    Sammanfattning : This thesis focuses on evaluation and analysis of capillary microcirculatory changes in the skin, that can be improved and extended by computer assisted video microscopy. Capillary microscopy has been used extensively, both in clinical practice and research, to study different phenomena in the microvasculature of the skin, mainly in the nailfold of fingers and toes where a large portion of the capillary loop can be observed.

    Sammanfattning : Semiconductor nanowires are studied by using transmission electron microscopy (TEM) based methods in this work. In the first section, the growth mechanism of gallium arsenide nanowires grown by chemical beam epitaxy is investigated. The nanowires are epitaxially grown from a gallium arsenide substrate by using gold seed particles as catalysts. LÄS MER

    Sammanfattning : During recent years, new types of materials have been discovered with unique properties. One family of such materials are two-dimensional materials, which include graphene and MXene. These materials are stronger, more flexible, and have higher conductivity than other materials. As such they are highly interesting for new applications, e. LÄS MER
