(a) Panel illustrating the data structure; (b) Panel showing the prior knowledge of a list of anticipated principal chemical species in the sample, which is indispensable for the chemical mapping in this approach. Panel (c) illustrates the quantification procedures including the linear combination fitting, the color coding, and the tomographic reconstruction. Panel (d) shows the 3D mesoscale structural and chemical heterogeneity of a cluster of partially reduced NiO electrode particles
