  3. 2. Spectroscopic studies of kaolinite surfaces

    Författare :Ursula Johansson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : In this thesis, specific surface reactions on kaolinite have been investigated. The methods used are diffuse reflectance Fourier transform (DRIFT), FT-Raman and micro Raman spectroscopy. The deuterium exchange of the hydroxyl protons of kaolinite has been studied. LÄS MER

  4. 3. Spontaneous and stimulated X-ray Raman scattering

    Författare :Yu-Ping Sun; Faris Gel'mukhanov; Vincenzo Carravetta; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resonant X-ray scattering; resonant Auger scattering; rotational Doppler broadening; XFEL pulse; Atomic and molecular physics; Atom- och molekylfysik; Spectroscopy; Spektroskopi;

    Sammanfattning : The present thesis is devoted to theoretical studies of resonant X-ray scattering and propagation of strong X-ray pulses. In the first part of the thesis the nuclear dynamics of different molecules is studied using resonant X-ray Raman and resonant Auger scattering techniques. LÄS MER

  5. 4. Raman Spectroscopy and Hyperspectral Analysis of Living Cells Exposed to Nanoparticles

    Författare :Linnea Ahlinder; Lars Österlund; Ioan Notingher; Uppsala universitet; []
    Nyckelord :Raman spectroscopy; Hyperspectral analysis; Multivariate data analysis; Nanotoxicology; Graphene oxide; Iron oxide; Titanium dioxide; Cells;

    Sammanfattning : Nanoparticles, i.e. particles with at least one dimension smaller than 100 nm, are present in large quantities in ambient air and can also be found in an increasing amount of consumer products. It is known that many nanomaterials have physicochemical properties that differ from physicochemical properties of the same material in bulk size. LÄS MER

  7. 5. Methods, Instrumentation and Mechanisms for Optical Characterization of Tissue and Treatment of Malignant Tumours

    Författare :Sara Pålsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; temperature; perfusion; PDT; photodynamic therapy; mechanisms; tissue characterization; instrumentation; optical biopsy; fluorescence spectroscopy; spectroscopy techniques; Raman spectroscopy; interstitial photodynamic therapy; photodynamic threshold dose; Atomic and molecular physics; Atom- och molekylärfysik;

    Sammanfattning : In this thesis, different optical methods utilising visible light for characterization of tissue have been developed and evaluated. The feasibility of many of these methods has been demonstrated in the laboratory or in animal experiments. LÄS MER
