11. Creating and Probing Extreme States of Materials : From Gases and Clusters to Biosamples and Solids
Sammanfattning : Free-electron lasers provide high intensity pulses with femtosecond duration and are ideal tools in the investigation of ultrafast processes in materials. Illumination of any material with such pulses creates extreme conditions that drive the sample far from equilibrium and rapidly convert it into high temperature plasma. LÄS MER
12. The care of children : A cross-national comparison of parents’ expectations and experiences
Sammanfattning : As a point of departure, this thesis is motivated by the big changes which have taken place in most Western European countries since the 1970s, with an increase in female labour market participation and, to some extent, men’s increased share of the domestic work. There is also a debate as to whether France, having a fairly extensive family support,should be categorised as closer to the Scandinavian countries or together with countries with more restrictive family policy such as Italy and Germany, and thus belonging to the conservative regime cluster as defined by Gösta Esping-Andersen.

13. There Is an Alloy at the End of the Rainbow: Structure and Optical Properties From Bulk to Nano
Sammanfattning : Mixing different chemical species and decreasing dimensions to the nanoscale are two powerful approaches for improving materials. In both cases new properties emerge, and structure, composition, and chemical ordering can be tuned to tailor materials for specific purposes. LÄS MER
14. Free Molecular and Metal Clusters Studied by Synchrotron Radiation Based Electron Spectroscopy
Sammanfattning : The main purpose of this Thesis is the experimental characterization of the electronic and geometric structures of objects called clusters. A cluster consists of a finite group of bound atoms or molecules. Due to its finite size, it may present completely different properties than those of the isolated atom and the bulk. LÄS MER
15. Rare-gas Clusters Studied by Electron Spectroscopy : Structure of Heterogeneous Clusters and Effects of Electron Scattering on Auger Decay
Sammanfattning : In this Thesis experimental studies of nano-clusters using synchrotron radiation based photoelectron (UPS and XPS) and Auger Electron Spectroscopy (AES) are presented. The investigations may be divided into two parts where the first reports on the structure of heterogeneous two component clusters, and the second concerns electronic decay processes. LÄS MER
