16. Crystallographic studies of non-equilibrium structural changes in cathode materials
Abstract : Battery cathode materials are a key focus for improvement of Li-ion battery chemistries due their limits in terms of capacity and cost. During insertion and extraction of Li, many cathode materials exhibit structural changes, ranging from e.g. phase transitions to amorphization. READ MORE

17. Structure Modeling with X-ray Absorption and Reverse Monte Carlo: Applications to Water
Abstract : Water is an important substance. It is part of us, of our environment, and is a fundamental prerequisite for the existence of life as we know it. The structure of water is still, after over 100 years of research on the subject, however under debate. READ MORE

18. Flash Diffractive Imaging in Three Dimensions
Abstract : During the last years we have seen the birth of free-electron lasers, a new type of light source ten billion times brighter than syncrotrons and able to produce pulses only a few femtoseconds long. One of the main motivations for building these multi-million dollar machines was the prospect of imaging biological samples such as proteins and viruses in 3D without the need for crystallization or staining.

19. Raman Scattering and Neutron Diffraction Studies of Manganites and Cuprates
Abstract : This thesis is devoted to experimental studies of two classes of strongly correlated transition metal oxides, namely cuprates and manganite perovskites. Manganites generally display complex phase diagrams, including the so-called colossal magnetoresistance effect. READ MORE

20. Becoming Together and Apart : technoemotions and other posthuman entanglements
Abstract : Using social media and norm-breaking material as an empirical touchstone this thesis elaborates, investigates and explores the entangled relationships between humans and technology in social media settings. Guided by uncomfortable, emotional and bodily online sharing the thesis gives voice to stories that are seldom heard, by people whose lives are rarely spoken of. READ MORE
