1. 3D Electron Diffraction : Application and Development towards High-quality Structure Determination
Sammanfattning : Electron crystallography has been proven to be effective for structure determination of nano- and micron-sized crystals. In the past few years, 3D electron diffraction (3DED) techniques were used for the structure solution of various types of complex structures such as zeolites, metal-organic frameworks (MOF) and pharmaceutical compounds.

2. Diffraction in high-energy collisions
Sammanfattning : This thesis concerns itself with low-momentum-transfer processes in high-energy particle collisions. These processes cannot be described in the framework of the fundamental theory of quantum chromodynamics (QCD), but rely on a pre-QCD approach, the Regge theory. LÄS MER
3. Cells in Culture, Cells in Suspense : Practices of Cultural Production in Foetal Cell Research
Sammanfattning : Parkinson’s disease is a neurodegenerative affliction to which researchers have long striven to find a cure. The human embryo is a source of vital cells used in regenerative medicine, as well as a powerful symbol of life. LÄS MER
4. Exploiting reciprocal space : Electron diffraction, textures and precession
Sammanfattning : Electron crystallography emerges as a new tool for accurate structure determination of very small crystals. In order to exploit the full potential of electron diffraction, the methods for data acquisition and processing have to be developed towards the high standards of X-ray crystallography. LÄS MER
5. Strain Mapping of Single Nanowires using Nano X-ray Diffraction
Sammanfattning : Nanowires are explored as basic components for a large range of electronic devices. The nanowire format offersseveral benefits, including reduced material consumption and increased potential for combining materials to formnew novel heterostructures. LÄS MER
