资源简介：

Ringwoodite is known for its unique ability to incorporate significant amounts of water into its structure, with profound implications for both geophysical and geochemical processes in the Earth's mantle. This research aims to explore the relationship between water content in ringwoodite and its electrical conductivity mechanism as a function of pressure (up to 30 GPa), using a quantum crystallography (QC) approach. The use of QC offers a better understanding of interactions within the crystal and its energetic properties. Multipole density model refinement demands excellent quality of single-crystal XRD data, characterized by high resolution and completeness. Moreover, DAC restricts access to reciprocal space and introduces experimental noise. ID-27 at ESRF offers exceptional solutions, excellent detector, high brilliance of the beam. These factors effectively address all the experimental challenges. Proposed research will enhance the role of QC in Earth and material sciences at HP.
