  2. 1. Heavy Metal Superantigen : Genetic Regulation of Lymphocyte Activation by HgC12

    Author : Yun Jiang; Peter Mathieson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; immunologi; Immunology;

    Abstract : Injections of subtoxic doses of HgCl2 (mercuric chloride) cause a systemic autoimmune disease in genetically predisposed rats and mice. My work was designed to elucidate how HgCl2 induces lymphocyte activation and how the response to HgCl2 is regulated in susceptible and resistant strains. READ MORE

  4. 2. High frequency electronic packaging : SBU-materials, material characterization, simulation and processing

    Author : Christian Johansson; Hjalmar Hesselbom; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dielectric loss; high frequency electrical characterization; microwave circuits; multilayer thin film technology; ORMOCER; permittivity; sequential build up; silicone elastomer;

    Abstract : Electronic packaging continues to move towards improved performance and lower cost. Requirements of higher performance, reduced size, weight and cost of both High Density Interconnects (HDI) and high frequency (HF) devices has led to the search for new: materials, material combinations, methods, processes and production equipment.

    Abstract : A new manufacturing paradigm may lower the cost and environmental impact of existing products, as well as enable completely new products. Large scale, roll-to-roll manufacturing of flexible electronics and other functionality has great potential. READ MORE

  6. 4. Cytokine responses in metal-induced allergic contact dermatitis : Relationship to in vivo responses and implication for in vitro diagnosis

    Author : Jacob Minang; Marita Troye-Blomberg; Niklas Ahlborg; Rik Scheper; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metal allergy; Contact dermatitis; cytokines; ELISA; ELISpot; Flow cytometry; Immunology; Immunologi;

    Abstract : Transition metals such as nickel (Ni), cobalt (Co), palladium (Pd), chromium (Cr) and gold (Au) are widely used as alloys in jewelry and biomaterials such as orthodontic and orthopaedic appliances. These metals also cause cell-mediated allergic contact dermatitis (ACD) reactions in a significant proportion of the population upon prolonged direct exposure. READ MORE

  7. 5. Experimental investigations of model catalytic surface reactions on metal and metal oxide surfaces

    Author : Kess Marks; Henrik Öström; Ellen Backus; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kemisk fysik; Chemical Physics;

    Abstract : In the development of renewable energies catalysis plays an important role, for example in the production of H2 gas that drives fuel cells, or in the decomposition of annoying by-products of renewable energy production. Most catalysts and catalytic processes currently used in the industry have their roots in macroscopic empirical investigations and trial and error-based optimization. READ MORE
