New project takes aim at theory-experiment gap in materials data

$Venn diagram showing the overlap between different types of data. The circle representing crystal structure and diffraction is overlapped with circles labelled nonlinear optical, topological crystals, topological phoon, and single crystals growth. Circles labelled "layered structures" and "2D ferroelectric" also appear.$
