2. 1. Growth and Nano-structural Studies of Metallic Multilayer for X-ray Mirrors

   Author : Naureen Ghafoor; Jens Birch; Gabriella Andesson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft X-rays; Multilayer Mirrors; X-ray microscope; Materials science; Teknisk materialvetenskap;

   Abstract : A part of the Ph.D. project focused on growth and characterization of metal multilayers is presented in this licentiate thesis. The main interest in carrying out this research is to develop highly reflective normal-incidence condenser mirrors for soft X-ray microscopy studies in the water window (λ=2. READ MORE

4. 2. Materials Science of Multilayer X-ray Mirrors

   Author : Naureen Ghafoor; Jens Birch; Claude Montcalm; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft X-rays; Multilayer mirrors; Magnetron sputtering; Interface engineering; Materials science; Teknisk materialvetenskap;

   Abstract : This thesis treats the reflective and structural properties of multilayer structures. Soft X-ray multilayer mirrors intended as near-normal incidence reflective optics and polarizers in the water window (λ=2.4-4.4 nm) are the main focus. READ MORE

5. 3. Hands-on osteoporosis screening with digital x-ray radiogrammetry

   Author : Michael Wilczek; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : According to epidemiological studies about one third of women and one fifth of men over 50 years will experience a fragility fracture. These fractures account for substantial mortality, morbidity and health care cost. Osteoporosis is a silent disease and thus often goes undiagnosed for a long time. READ MORE

6. 4. X-ray computed tomography to study moisture distribution in wood

   Author : José Couceiro; Lars Hansson; Mike Milota; Luleå tekniska universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Träteknik; Wood Science and Engineering;

   Abstract : X-ray computed tomography (CT) has been used as an analysing tool for different features in wood research since the beginning of the1980s, but it can also be used to study wood-water interactions in different ways, such as by determining wood moisture content (MC). The determination of wood MC with CT requires two CT images: one at the unknown moisture distribution and a second one at a known reference MC level, usually at oven-dry condition. READ MORE

7. 5. Layer formation on quartz particles during fluidized bed combustion/gasification of woody biomass

   Author : Hanbing He; Christoffer Boman; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Abstract : The formation of sticky layers on bed particles has been considered as a prerequisite for bed agglomeration in fluidized bed combustion and gasification of woody fuels. In addition, the layer formed makes the bed particle less resistant against fragmentation. The fragments from quartz particles can result in deposition. READ MORE
