  1. 1. Thermally Expandable Microspheres Prepared via Suspension Polymerization - Synthesis, Characterization, and Application

    Författare :Magnus Jonsson; Eva Malmström Jonsson; Søren Hvilsted; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermally expandable microspheres; Polymer chemistry; Polymerkemi;

    Sammanfattning : Thermally expandable microspheres are polymeric core/shell particles in which a volatile hydrocarbon is encapsulated by a thermoplastic shell. When these microspheres are heated, they expand and increase their volume dramatically. LÄS MER

  3. 2. Conducting Polymer Electrodes for Oxygen Reduction Reaction

    Författare :Evangelia Mitraka; Xavier Crispin; Magnus Berggren; Magnus Jonsson; Mikhail Vagin; Björn Winther-Jensen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Both the pollution level of the environment and the increasing energy demands have stimulated intense research on the development of low-cost environmentally-friendly energy conversion and storage systems with high efficiency, such as metal-air batteries and fuel cells.One of the most essential parts of both fuel cells and metal–air batteries is the air-electrode which is responsible for the reduction of O2.

  4. 3. Biochemical Studies of Semenogelins with Emphasis on Zinc-Binding Properties

    Författare :Magnus Jonsson; Malmö Klinisk kemi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sexualitet; sexuality; Obstetrik; gynekologi; andrologi; reproduction; andrology; gynaecology; Obstetrics; Klinisk kemi; Clinical chemistry; gel-forming proteins; surface plasmon resonance; prostate-specific antigen; protein C inhibitor; seminal plasma; zinc; semen; semenogelin; reproduktion;

    Sammanfattning : Semenogelins I and II (SgI and SgII) are homologous and rapidly evolving proteins that have a repetitive primary structure and are synthesized mainly in the seminal vesicles. Upon ejaculation, a gelatinous coagulum is formed when the semenogelin-rich secretion from the seminal vesicles is mixed with the prostate secretion, which contains high concentrations of zinc(II) and proteases.

  5. 4. Methodological aspects on carotid artery intervention

    Författare :Magnus Jonsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :carotid artery stenosis;

    Sammanfattning : In Sweden, approximately 25000 patients suffer a cerebral infarction (stroke) annually. Stroke ranks as the third-leading cause of death, and is the leading cause of functional impairment. Carotid artery stenosis accounts for approximately 15% of all strokes and almost all of these are theoretically preventable. LÄS MER

  7. 5. Carbon-nanotube-based nanoelectromechanics

    Författare :Magnus Jonsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electromechanical instabilities; multi-mode excitations; NEMS; suspended carbonnanotubes; Nanoelectromechanicalsystems; non-linearresonances; nanorelay; carbon nanotubes; surface forces;

    Sammanfattning : Carbon nanotubes, a novel material with extraordinary mechanical and electrical properties, are good candidates for designing nanoelectromechanical systems. The typical length scale of these systems is nanometers and an important characteristic is a coupling between electrical and mechanical degrees of freedom. LÄS MER
