In-situ synchrotron radiation X-ray structural studies of soft crystals.

Keywords
Synchrotron radiation X-ray diffraction, Powder X-ray Diffraction, Single Crystal X-ray Diffraction, In-situ measurement
Co-Researcher
Co-Researcher: Hidetaka Kasai (Faculty of Pure and Applied Sciences, University of Tsukuba, Assistant Professor)

Research Outline

The aim of this study is to reveal structural changes of “soft crystal” applying external weak stimulus by single crystal x-ray diffraction, powder x-ray diffraction and pair distribution function measurement using synchrotron radiation (SR) X-ray. We will also perform structure determinations of novel materials developed in the present innovative areas from SR single crystal and powder diffraction.

To carry out in situ SR x-ray diffraction study effectively, we will develop an attachment for SR in-situ measurement. The attachment will be developed using in house single crystal and powder diffractometer at University of Tsukuba. We will establish measurement procedure at university. We will install the developed attachment in the SR facilities. It will enables us to perform time resolved measurement with seconds order time scale. We would like to contribute a development of research field of “Soft Crystal” using in-situ SR x-ray diffraction.
