  2. 1. Light scattering and absorption in tissue - models and measurements

    Author : Annika M K Enejder; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tissue optical properties; Light absorption; Fluorescence spectroscopy; Atomic and molecular physics; NIR spectroscopy; Fysicumarkivet A:1997:Enejder; Light scattering; Atom- och molekylärfysik;

    Abstract : In this work a number of theoretical models, describing light propagation in matter, have been applied to and developed for the examination of tissue. The aim was to model the light scattering and absorption in tissue in order to improve the understanding of underlying mechanisms of laser-based diagnostics and treatment modalities utilised for cancer and cardiovascular diseases.

  4. 2. LiMn2O4 as a Li-ion Battery Cathode. From Bulk to Electrolyte Interface

    Author : Tom Eriksson; Michael M. Thackeray; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; cathode materials; lithium manganese oxide; interface; surface layer; electrode kinetics; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : LiMn2O4 is ideal as a high-capacity Li-ion battery cathode material by virtue of its low toxicity, low cost, and the high natural abundance of Mn. Surface related reactions and bulk kinetics have been the major focus of this work. READ MORE

  5. 3. LiFeSO4F as a Cathode Material for Lithium-Ion Batteries : Synthesis, Structure, and Function

    Author : Adam Sobkowiak; Fredrik Björefors; Kristina Edström; Anna Andersson; M. Rosa Palacin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; cathode; LiFeSO4F; tavorite; triplite; synthesis; performance; structure; coating; PEDOT; XRD; Mössbauer spectrocopy; SEM; TEM; electrochemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : In this thesis, two recently discovered polymorphs of LiFeSO4F, adopting a tavorite- and triplite-type structure, were investigated as potential candidates for use as cathode materials in Li-ion batteries. The studies aimed at enriching the fundamental understanding of the synthetic preparations, structural properties, and electrochemical functionality of these materials. READ MORE

  6. 4. Laser Diagnostics of HCCI and Partially Premixed Combustion

    Author : Leif Hildingsson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low temperature combustion; Motorer; Motors and propulsion systems; Teknik; Technological sciences; PIV; in-cylinder flow structures; hydroxyl; OH; partially-oxidized fuel; formaldehyde; HCOH; LIF; diesel combustion; partially premixed combustion; PPC; HCCI; framdrivningssystem;

    Abstract : The work presented in this thesis deals with measuring in-cylinder combustion species and events using different laser-based diagnostic methods. A variety of engine operating modes, like HCCI and partially premixed diesel combustion, have been investigated. READ MORE

  7. 5. Osteotropic cytokines : expression in human gingival fibroblasts and effects on bone

    Author : Py Palmqvist; Andersson Göran; Umeå universitet; []
    Keywords : osteoblasts; osteoclasts; fibroblasts; cytokines; IL-6; LIF; OSM; IL-4; IL-3; bone resorption; odontologi; Odontology;

    Abstract : Bone metabolism is regulated by endocrine and paracrine signalling molecules influencing bone cells in the continuously remodelling bone tissue. These molecules include a variety of osteotropic stimulatory and inhibitory cytokines. READ MORE
