  2. 16. The initial atmospheric corrosion of copper and zinc induced by carboxylic acids : Quantitative in situ analysis and computer simulations

    Author : Harveth Gil; Christofer Leygraf; Johan Tidblad; Stuart Lyon; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmospheric corrosion; copper; zinc; carboxylic acids; modeling; GILDES; in situ; quantification;

    Abstract : Degradation of metals through atmospheric corrosion is a most important and costly phenomenon with significant effects on, e.g., the lifespan of industrial materials, the reliability of electronic components and military equipment, and the aesthetic appearance of our cultural heritage.

  4. 17. In situ measurements of radionuclide concentration in soil : An investigation into detector properties and methods

    Author : Johan Kastlander; Christoph Bargholtz; Mats Isaksson; Stockholms universitet; []
    Keywords : In situ gamma-ray spectrometry; LaBr3; CdTe; Cs-137; soil samples; fysik; Physics;

    Abstract : In case of a release of radioactive nuclides into the environment it is necessary to  have reliable methods to estimate the potential effect on people and the ecosystem. In this context the total activity deposited, the elemental composition and the depth distribution are of importance. READ MORE

  5. 18. Immune reactions in the skin : studies on Langerhans cell and lymphocyte interactions in vitro and in situ

  6. 19. Connective tissue contraction in wound healing : An experimental study in vivo and in vitro

    Author : M. Reza Ghassemifar; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Contraction of connective tissue is an important part of tissue repair that reduces the wound space and helps to decrease the formation of scar tissue, both of which are needed to restore tissue integrity. In the present study, certain cellular mechanisms that are active during connective tissue contraction were assessed and the influence of transforming growth factor-. READ MORE

  7. 20. In-situ phase studies of the Zr-H system

    Author : Tuerdi Maimaitiyili; Malmö högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zirconium hydride; synchrotron X-ray diffraction; neutron diffraction; phase transformation; in-situ hydrogen charging; hydrogen related degradation; in situ phase transformation; hydrogen embrittlement; hydrogen charging; zirconium hydride; γ-ZrH; synchrotron X-ray diffraction; neutron diffraction; hydrogen induced degradation;

    Abstract : Zirconium alloys are widely used in the nuclear industry because of their high strength, good corrosion resistance and low neutron absorption cross-section. However, zirconium has strong affinity for hydrogen, which may lead to hydrogen concentration build-up over time during a corrosion reaction when exposed to water. READ MORE
