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

17. On enhancement of bone formation using 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

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

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

20. Atom Probe Tomography of TiSiN Thin Films
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
