  1. 1. Microfabrication of Optical Components in Synthetic Diamond : Infrared Optics for Applications  in Astronomy and Spectroscopy

    Författare :Ernesto Vargas Catalan; Mikael Karlsson; Thomas Schuelke; Uppsala universitet; []
    Nyckelord :Diamond; microfabrication; microoptics; astronomy; IR-spectroscopy; corongraph; waveguide;

    Sammanfattning : Infrared optics is a broad general term, relevant to a range of fields. The manufactured diamond optical components utilized within this thesis were applied to both astronomy, in which direct imaging of star system using large ground-based telescopes and diamond coronagraphs was performed, and in absorption spectroscopy probing solvents and proteins using a tuneable quantum cascade laser and diamond waveguides.

  3. 2. Microfabrication for Biological Applications. Preparation, Characterization and Biological Evaluation

    Författare :Julie Gold; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asbestos; surface spectroscopy; lithography; microfabrication; fibers; surface modification; biomaterials;

    Sammanfattning : Foreign materials are intentionally placed into patients in the form of medical devices for replacing or repairing damaged portions of the body. Materials also enter the body unintentionally in the form of particulates and fibers, and can then have damaging effects, such as the formation of disease or even cancer. LÄS MER

  5. 4. Microfabrication of miniature x-ray source and x-ray refractive lens

    Författare :Carolina Ribbing; Robert Baptist; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; microfabrication; diamond; field emission; Teknisk fysik; Engineering physics; Teknisk fysik; teknisk fysik med inriktningen mikrosystemteknik; engineering science with specialization in microsystems technology;

    Sammanfattning : In several x-ray related areas there is a need for high-precision elements for x-ray generation and focusing. An elegant way of realizing x-ray related elements with high precision and low surface roughness is by the use of microfabrication; a combination of semiconductor processing techniques and miniaturization.

    Sammanfattning : This thesis summarises work towards a Lab-on-Chip (LOC). The request for faster and more efficient chemical and biological analysis is the motivation behind the development of the LOC-concept. Microfluidic devices tend to become increasingly complex in order to include, e.g. LÄS MER
