  1. 26. Bilayer Light-Emitting Electrochemical Cells for Signage and Lighting Applications

    Författare :E. Mattias Lindh; Ludvig Edman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; Light-emitting electrochemical cell; Signage; Display; Luminescent line art; Inkjet printing; Direct-write printing; fysik; Physics; Electronics; elektronik;

    Sammanfattning : Artificial light surrounds us in a manifold of shapes. It is mainly utilized for illumination, but also for graphical communication of complex and evolving messages and information, among other things. It can be generated in different ways with incandescent lamps and fluorescent tubes constituting two common examples. LÄS MER

  3. 27. Development of Magnetomotive Ultrasound Imaging

    Författare :Maria Evertsson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetomotive ultrasound; molecular imaging; contrast angents; multimodal imaging; sentinel lymph node;

    Sammanfattning : The earlier abnormalities coupled with disease can be discovered in the body, the larger is the chance to survive the disease. Molecular imaging is a growing research field which aims to detect these abnormalities at a molecular level, when the chance of survival is still high. LÄS MER

  4. 28. Adipose Tissue Heterogeneity - Development and Application of Nonlinear Microscopy Methods

    Författare :Alexandra Paul; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; least squares decomposition; stem cells; multivariate spectral analysis; obesity; adipose tissue; adipogenesis; broadband coherent anti-Stokes Raman scattering; extracellular matrix;

    Sammanfattning : Although the negative health impacts of obesity have been well documented, the number of overweight or obese patients has and is predicted to continue rising. One of the causal factors of obesity is a constant positive energy balance mainly from excessively high caloric intake from food compared with limited physical activity (caloric expenditure).

  5. 29. Quantified In Situ Analysis of Initial Atmospheric Corrosion : Surface heterogeneity, galvanic effects and corrosion product distribution on zinc, brass and Galvalume

    Författare :Ping Qiu; Christofer Leygraf; Béatrice Hannoyer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmospheric corrosion; Zinc; Brass; Galvalume; In Situ; Quantification.; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The interaction of the surface of a pure metal or an alloy with the surrounding atmosphere occurs in a highly complex interfacial regime. During atmospheric corrosion this interfacial regime involves the metal surface, often covered by a naturally formed oxide layer of a few nanometers thickness; an aqueous adlayer, typically with a thickness of a few to a few tens of nanometers, and the atmosphere from which airborne particles, oxygen, and gaseous pollutants dissolve into the adlayer and influence the atmospheric corrosion process.

  7. 30. Electrochemically etched pore arrays in silicon for X-ray imaging detectors

    Författare :Xavier Badel; Jan Linnros; Volker Lehmann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrophysics; Elektrofysik; Electrophysics; Elektrofysik;

    Sammanfattning : Digital devices have now been introduced in many X-ray imaging applications, replacing slowly traditional photographic films. These devices are preferred as they offer real time imaging, easy handling and fast treatment of the images. LÄS MER
