1. Education and dementing disorders : the role of schooling in dementia and cognitive impairment
Sammanfattning : This doctoral thesis aimed to investigate the complex relationship between education, dementias, and cognitive impairment. Two different databases were used: the Faenza and the AIDS Projects. LÄS MER
2. High-Aspect Ratio Nanofabrication for Hard X-Ray Zone Plates
Sammanfattning : Hard x-ray nanoimaging enables structural investigations of new materials for many applications. For high-resolution experiments, zone plate x-ray optics are commonly chosen.Two methods of zone plate nanofabrication are presented in this thesis.Zone plates are circular diffraction gratings with radially decreasing grating period.

3. Zone Plates for Hard X-Ray Free-Electron Lasers
Sammanfattning : Hard x-ray free-electron lasers are novel sources of coherent x-rays with unprecedented brightness and very short pulses. The radiation from these sources enables a wide range of new experiments that were not possible with previous x-ray sources. Many of these experiments require the possibility to focus the intense x-ray beam onto small samples. LÄS MER
