  3. 3. Compact diode-pumped solid-state lasers

    Detta är en avhandling från Stockholm : Fysik

    Författare :Stefan Spiekermann; [2004]
    Nyckelord :visible lasers; UV lasers; solid-state lasers;

    Sammanfattning : Compact diode-pumped solid-state lasers (DPSSL) arecontinuously replacing traditional gas lasers as well asenabling completely new technology. However, compact and costefficient designs are required to satisfy end-user demands. Theaim of this thesis was therefore to investigate novel laserdesigns for given applications considering these demands. LÄS MER

  4. 4. Solid state characterisation and compaction behaviour of pharmaceutical materials

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Christina Gustafsson; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; Solid-state; Tablet; Thermal analysis; Cellulose; Spectroscopy; NMR; NIR; FT-IR; Crystallinity; MVDA; FARMACI; PHARMACY; FARMACI; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Sammanfattning : In this thesis, factors important in tableting operations and for tablet properties have been studied and characterised by different spectroscopic techniques as well as by some more conventionally used particle characterisation techniques. The spectroscopic techniques solid-state NMR, FT-IR and NIR spectroscopy, proved to be valuable tools in the estimation of particle and tablet properties, offering both specificity and sensitivity in the measurements.
