  1. 1. An Insight into the Critical Role of Microstructure and Surface Preparation on Localized Conversion Coating Deposition on Cast Al Alloys

    Författare :Salil Sainis; Caterina Zanella; Ehsan Ghassemali; Marjorie Olivier; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium alloys; cast Al-Si alloys; conversion coating treatment; cerium; localized deposition; surface preparation; microstructure; SEM; FIB-SEM; AFM-SKPFM; Aluminiumlegeringar; gjutna Al-Si legeringar; Cerium; lokal deposition; omvandlingsbeläggningsbehandling; förbehandling av yta; mikrostruktur; SEM; FIB-SEM; AFM-SKPFM;

    Sammanfattning : The spontaneous cerium conversion coating formation over aluminium alloys is affected by the chemical process conditions, the surface preparation prior to conversion treatment and the microstructure of the underlying alloy. Most research performed until now focus only on the former whereas the influence of the latter two is poorly understood. LÄS MER

  3. 2. Acute pancreatitis - Cellular response and dynamic inflammatory changes

    Författare :Marwan Dib; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Veterinary medicine:surgery; inflammatory mediators.; adhesion molecules; endothelial barrier dysfunction; inflammatory response; mast cell; abdominal sepsis; Acute pancreatitis; physiology; pathology; clinical studies; Veterinärmedicin:kirurgi; fysiologi; patologi; kliniska studier;

    Sammanfattning : Acute pancreatitis (AP) is a common disorder where underlying mechanisms for the local initiating events in the pancreas, the systemic dissemination of the inflammatory response and the remote organ dysfunction still are unclear. The aim of the present study was to further characterize the dynamics and sequence of the immune response in AP, and to determine the cellular origin of the initiating events. LÄS MER

  4. 3. Epitaxial Growth and Characterization of SiC for High Power Devices

    Författare :Jawad ul Hassan; Peder Bergman; Hidekazu Tsuchida; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Silicon Carbide (SiC) is a semiconductor with a set of superior properties, including wide bandgap, high thermal conductivity, high critical electric field and high electron mobility. This makes it an excellent material for unipolar and bipolar electronic device applications that can operate under high temperature and high power conditions. LÄS MER
