  2. 1. Synthesis and Characterization of Nanoprobes for X-Ray Fluorescence Computed Tomography (XFCT) Bio-imaging

    Author : Yuyang Li; Muhammet Toprak; Hans Hertz; Ender Suvaci; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : X-ray fluorescence computed tomography (XFCT) is an emerging biomedical imaging technique. The KTH-XFCT laboratory system offers a characteristic 24 keV emission line, and high spatial resolution (200 ?m) images. XFCT as a newly emerging modality also requires the exploration and development of suitable contrast agents. READ MORE

  4. 2. Colloidal zeolites : from nucleation to zoned films by seeded growth

    Author : Qinghua Li; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : The work presented in this thesis concerns the investigation of nucleation kinetics for colloidal zeolites, especially the determination of the nucleation period during crystallization. It also concerns the use of colloidal TPA-silicalite-1 for the preparation of zoned MFI films. READ MORE

  5. 3. Endothelin-1-immunoreactive protein and neuroendocrine differentiation and nerve supply in human non-neoplastic and neoplastic adrenal cortex : Immunohistochemical, ultrastructural, and biochemical findings

    Author : Qing Li; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; adrenal cortex; human; endothelin-related protein; innervation; neuroendocrinedifferentiation; immunohistochemistry; electron microscopy; biochemistry; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Abstract : The occurrence and distribution of endothelin (ET)-1-immunoreactive (ir) protein, neuro-endocrine markers and neurohormonal peptides in endocrine cells and nerves in human non-neoplastic and neoplastic adrenal cortex are described.ET-1-ir cell groups were regularly seen in human adrenal cortex, mainly in zona fasciculata, but not in the medulla.

  6. 4. Measurement of the Dalitz Plot Distribution for η→π+π−π0 with KLOE

    Author : Li Caldeira Balkeståhl; Andrzej Kupsc; Tord Johansson; Simon Eidelman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Quark masses; Hadronic decays; Light mesons; Meson-meson interactions; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

    Abstract : The mechanism of the isospin violating η→π+π−π0 decay is studied in a high precision experiment using a Dalitz plot analysis. The process is sensitive to the difference between up and down quark masses. READ MORE

  7. 5. Toward Energy-efficient Physical Vapor Deposition : Routes for Replacing Substrate Heating during Magnetron Sputtering by Employing Metal Ion Irradiation

    Author : Xiao Li; Grzegorz Greczynski; Ivan Petrov; Lars Hultman; Jyh-Wei Lee; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PVD; Magnetron sputtering; Thin films; HiPIMS; TiAlN; Energy efficiency;

    Abstract : In this Thesis, magnetron sputtering is perfected as an environmental-friendly deposition technique. I performed systematic studies of a novel approach - hybrid high-power impulse and dc magnetron co-sputtering (HiPIMS/DCMS) with metal-ion-synchronized substrate bias pulses. READ MORE
