    Author : Dennis Visser; Srinivasan Anand; Alvaro Blanco; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; semiconductor materials; c-Si; a-Si; GaInP; TiO2; ZnO; nanostructuring; light manipulation functions; top-down fabrication; embossing; FDTD simulations; nanowires; nanopillars; nanodisks; microcones; optical response; reflectance; transmittance; absorbance; spectrophotometry; photoluminescence; Mie resonators; mode coupling; broadband anti-reflection; light extraction enhancement; optical sensing; optical color filters; color conversion; Optik och fotonik; Optics and Photonics;

    Abstract : Structuring of semiconductor materials is utilized in many optoelectronic devices, e.g, in order to make them more efficient, cost-effective, and/or to obtain specific wavelength-engineered responses. Semiconductor materials are widely used in optoelectronic devices due to their favorable optical and electric properties. READ MORE

  5. 3. Novel Technique for Analysing Volatile Compounds in Indoor Dust : Application of Gas Chromatography – UV Spectrometry to the Study of Building-Related Illness

    Author : Anders Nilsson; Christer Tagesson; Verner Lagesson; Göran Strid; Linköpings universitet; []
    Keywords : acrylates adverse effects; air pollution; ultraviolet; indoor analysis; chromatography; gas; environmental exposure adverse effects; sick building syndrome etiology; dust; volatilization; Spectrophotometry; MEDICINE; MEDICIN;

    Abstract : It is now generally acknowledged that particulate air pollution can cause respiratory symptoms and that indoor dust particles may be associated with mucous membrane irritation and odour annoyance. One reason for this may be that dust particles adsorb large quantities of gases and other volatile compounds. READ MORE

  6. 4. Interfacing spectrophotometry to process liquors applications to kraft pulping

    Author : Xiaotian Yang; KTH; []
    Keywords : Kraft cooking; On-line; Sulfide; Lignin; Polysulfide excess sulfur; Anthraquinone-2-sulfonate; Anthraquinone; Nafion membrane; UV-Vis; ATR-probe; Spectrophotometric;

    Abstract : This thesis summarizes the outcome of work performed withthe objective to contribute to the knowledge and development ofthe kraft cooking process using spectrophotometricinterfaces.In kraft cooking, it is desirable to maximize the removal oflignin in the cook without loss of pulp strength.

  7. 5. Characterisation and treatment of patients with port wine stains with special reference to the emotional impact

    Author : Agneta Troilius; Dermatologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; capillary malformation; PWS; pulsed dye laser; laser doppler imager; ultrasound; psychosocial impact; depth; reflectance spectrophotometry; Dermatologi; venereologi; venereology; Dermatology;

    Abstract : This thesis covers 12 years of experience in treating patients with congenital capillary malformations, so called port wine stains (PWS). The wide variation in treatment response to laser therapy has developed a profound need for the development of objective devises to measure treatment outcome, so that the maximum effectiveness of therapy can be achieved without unnecessary treatments.
