  1. 21. Flame nanoengineering of antibiofilm surfaces for medical implants

    Författare :Felix J. Geissel; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Infection of bone implants is a major problem in the Healthcare sector today. Over the last years it has started to become more problematic due to biofilm formation and increasing antimicrobial resistance (AMR). A biofilm provides mechanical shielding to bacteria by ingulfing them leading to a less effective treatment with antibiotics. LÄS MER

  3. 22. Multifunctional Biomimetic Scaffolds Tailored for Cardiac Regeneration

    Författare :Abeni Wickham; Daniel Aili; Bo Liedberg; Carsten Werner; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Nature has had millions of years to perfect the structural components of the human body, but has also produced the dysfunctions that result in the cancers and diseases, which ruin that perfection. Congenital heart defects, and myocardial infarction lead to scarring that remodels heart muscle, decreasing the contractility of the heart, with profound consequences for the host. LÄS MER

  4. 23. ON THE COUPLING OF THE LOCALIZED PLASMON AND INTERBAND TRANSITIONS IN NICKEL NANOANTENNAS

    Författare :Zhaleh Pirzadeh Irannezhad; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Localized surface plasmon resonance; interband transition; nanoantenna; nickel nanoplasmonic; coupling;

    Sammanfattning : Interaction of light with metallic nanostructures smaller than the wavelength leads to excitation of collective oscillations of “free” conduction electrons. This effect leads to locally enhanced electric fields inside and outside the nanoparticle and is called localized surface plasmon resonance (LSPR). LÄS MER

  5. 24. Functional Fiber Based Materials for Microsystem Applications

    Författare :Carl Zandén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis explores the integration of functional electrospun micro- and nanofiber based materials in two fields of microsystem technology: fibrous scaffolds as cell culture substrates and fiber-reinforced metal matrix composites as thermal interface materials (TIMs).Electrospun structures have been found to carry great potential as biomimicking microenvironments for future tissue engineering and cell culture applications.

  7. 25. Development of a process model for a Peirce-Smith converter

    Författare :Andreas Lennartsson; Eetu-Pekka Heikkinen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Copper was one of the first metals ever extracted and used by mankind. It is used for its unique properties, like corrosion resistance, good workability, high thermal conductivity and attractive appearance. New mines are opened to maintain a supply of primary feedstock to copper smelters. LÄS MER
