  1. 16. Atom Probe Tomography of Hard Nitride and Boride Thin Films

    Author : David L. J. Engberg; Lars Hultman; Magnus Odén; Guido Schmitz; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Atom probe tomography APT ; Ceramics; Nitrides; Borides;

    Abstract : Hard ceramic thin films, including TiSiN, ZrAlN, ZrB2, and ZrTaB2, with applications for wear-resistant coatings, have been studied using atom probe tomography and correlated with several other analytical techniques, including X-ray diffraction, electron microscopy, and elastic recoil detection analysis. Outstanding obstacles for quantitative atom probe tomography of ceramic thin films have been surmounted. READ MORE

  2. 17. On enhancement of bone formation using local drug delivery systems

    Author : Ali Alenezi; Ann Wennerberg; Malmö universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone formation; local drug delivery systems;

    Abstract : Introduction: Despite that many reports have confirmed the long-term clinical success rates associated with implant treatment, implant failure to achieve and maintain osseointegration still occurs in many cases. Local and sustained drug release at the bone-implant interface is one of the strategies that have been suggested to improve the osseointegration. READ MORE

  3. 18. Pancreatic ductal adenocarcinoma : computed tomography for diagnosis, local staging and prediction of postoperative complications

    Author : Louiza Loizou; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Pancreatic ductal adenocarcinoma (PDAC) is a disease with a dismal prognosis, being the 4th leading cause of cancer deaths in Sweden and worldwide. The only potentially curative therapy is surgery. Unfortunately, by the time of diagnosis only 20% of patients have a resectable tumor and the overall 5-year survival rate does not exceed 5%.

  4. 19. Optical projection tomography based 3D-spatial and quantitative assessments of the diabetic pancreas

    Author : Tomas Alanentalo; Ulf Ahlgren; Raphael Scharfmann; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nkx; development; optical projection tomography; 3D visualisation; pancreas; beta-cell mass; insulitis; diabetes; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : The gastrointestinal tract comprises a number of digestive organs including the stomach and pancreas. The stomach is involved in the digestion and short term storage of food while the pancreas is a mixed endocrine and exocrine gland which provides the body with hormones and enzymes essential for nutritional utilisation.

  5. 20. Atom Probe Tomography of TiSiN Thin Films

    Author : David Engberg; Lars Hultman; Magnus Odén; Fang Liu; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis concerns the wear resistant coating TiSiN and the development of the analysis technique atom probe tomography (APT) applied to this materials system. The technique delivers compositional information through time-of-flight mass spectrometry, with sub-nanometer precision in 3D for a small volume of the sample. READ MORE
