Crystallography, Powder Diffraction, Structure Analysis

Main Research Activity
Crystal structure determination and refinement using powder diffraction, phase analysis, characterization of materials, methodology development, programming.

Mesostructured Materials Research
Diffraction analysis of mesostructured materials. Adaptation and development of crystallographic approaches (structure modeling, full-profile refinement, Fourier-map analysis) for application to poorly crystallized and mesostructured materials.

Derivative Difference Minimization (DDM) Method

A new method of full-profile refinement is developed on the basis of a derivative difference minimization. The method allows powder diffraction structure analysis independently of the background curve and may also be applicable in many other areas.
