Abstract: Due to the reduced informational content of powder diffraction data in comparison with single crystal diffraction, the challenge of increasing the accuracy in powder diffraction is of utmost importance. Several different ways of increasing accuracy in powder diffraction were investigated in the presented PhD thesis: possibilities and limitations of the maximum entropy method (MEM) for increasing accuracy of the electron density determination from high-resolution laboratory and synchrotron powder X-ray diffraction data, application of parametric refinement for the analysis of different models of coupling between strain and order parameter during structural phase transitions, and investigation of noble gas adsorption in MOFs by state of art laboratory and synchrotron powder diffraction.
