2. 1. 3D Electron Diffraction : Application and Development towards High-quality Structure Determination

   Author : Yunchen Wang; Wei Wan; Xiaodong Zou; Junliang Sun; Mauro Gemmi; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; three-dimensional electron diffraction; structure determination; rotation electron diffraction; Inorganic Chemistry; oorganisk kemi;

   Abstract : 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.

4. 2. Diffraction in high-energy collisions

   Author : Christine Rasmussen; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; QCD; Soft QCD; phenomenology; Diffraction; Multiparton Interactions; Dipole model; Initial state evolution; BFKL evolution.; Fysicumarkivet A:2019:Overgaard;

   Abstract : 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. READ MORE

5. 3. Cells in Culture, Cells in Suspense : Practices of Cultural Production in Foetal Cell Research

   Keywords : HUMANIORA; HUMANITIES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson s disease; Foetal cells; Praxis; Evidence Based Practice; Ethnology; Ethnography; Science studies; Diffraction; knowledge production; Ethical issues; ethics in practice; ethnology; ethnography; science studies; foetal cells; parkinson s disease; praxis; knowledge production; ethics in practice; evidence based medicine; diffraction; cell transplantation; cross-disciplinarity; epistemology;

   Abstract : 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. READ MORE

6. 4. Exploiting reciprocal space : Electron diffraction, textures and precession

   Author : Peter Oleynikov; Sven Hovmöller; Xiaodong Zou; Jean-Paul Morniroli; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; electron diffraction; texture patterns; precession electron diffraction; Inorganic chemistry; Oorganisk kemi;

   Abstract : 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. READ MORE

7. 5. Strain Mapping of Single Nanowires using Nano X-ray Diffraction

   Author : Susanna Hammarberg; NanoLund: Centre for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanotrådar; X-ray Diffraction; Strain mapping; XRF; III-V nanowire; perovskite nanowires; Diffraction; Nanowires; Strain mapping; XRD; XRF; MAX IV;

   Abstract : 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. READ MORE
