  1. 1. Correcting biological infrared spectroscopy data for atmospheric gases and Mie scattering

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Stéphan Pissot; [2020]
    Nyckelord :FTIR; spectroscopy; chemometrics; infrared absorption microscopy; atmospheric correction; scattering correction; Physics and Astronomy;

    Sammanfattning : Infrared absorption microscopy is a powerful chemometric tool with a wide variety of applications. It is, however, subject to considerable disturbances from atmospheric gases and scattering effects. LÄS MER

  3. 2. Optical Characterization of Lignin Nanoparticles

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Kristoffer Linder; [2020]
    Nyckelord :lignin; nanoparticles; nanoparticle; optical characterization; optical properties; surface plasmon resonance;

    Sammanfattning : Lignin is one of the main components of wood and plants that acts as a kind of glue providing mechanical strength. It is a main polymer component composed from three phenolic structures, i.e. p-hydroxyphenyl (H), guaiacyl (G) and syringyl (S) units. LÄS MER

  4. 3. Study of the Optical Properties of sp2-Hybridized Boron Nitride

    Master-uppsats, Linköpings universitet/Tillämpad optik

    Författare :Eduardo Antunez de Mayolo; [2014]
    Nyckelord :Spectroscopic ellipsometry; boron nitride; optical properties; materials characterization; III-V nitride semiconductors; cathodoluminescence; electron microscopy; Raman spectroscopy;

    Sammanfattning : Nitride-based semiconductor materials make it possible to fabricate optoelectronic devices that operate in the whole electromagnetic range, since the band gaps of these compounds can be modified by doping. Among these materials, the sp2-hybridized boron nitride has properties that make it a potential candidate for integration in devices operating in the short-wavelength limit, under harsh environment conditions, due to the strength of the B-N bond.

  5. 4. Radiation induced corrosion of copper

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Åsa Björkbacka; [2011]
    Nyckelord :Copper; radiation; gamma radiation; corrosion; SEM; IRAS; ICP; cuprite;

    Sammanfattning : The Swedish concept for storage of highly radioactive spent nuclear fuel is called the KBS-3 program. The proposed procedure is that the waste will be stored in a deep repository, 500 meters down in the Swedish bedrock, for 100 000 years. The fuel will be sealed inside cast iron cylinders surrounded by copper. LÄS MER

  7. 5. Characterization of InSb quantum dots in InAs matrix grown by molecular beam epitaxy for infrared photodetectors

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Laiq§ Hussain; [2011]
    Nyckelord :;

    Sammanfattning : Materials for the generation and detection of long wavelength IR radiation continue to be of considerable interest for many applications such as night vision, defense and security, rescue, life sciences, industrial processing etc. For this purpose photodetection based on InSb is a well known technology in mid wavelength (3-5 μm) range.
