Table 1 Elemental atomic fractions in LSM and SDC.

From: A high-entropy manganite in an ordered nanocomposite for long-term application in solid oxide cells

	LSM			SDC
		Counts	Cat.%		Counts	Cat.%
A-site LSM	Mn	22790	43.5 ± 0.5	La	50705	20.9 ± 0.7
	Ce	8227	15.7 ± 0.6	Mn	12420	5.1 ± 0.7
	La	11374	21.7 ± 0.6	Sr	2610	1.1 ± 0.2
	Sr	6588	12.6 ± 0.5	Ce	150310	61.9 ± 0.8
	Sm	3389	6.5 ± 0.4	Sm	26978	11.1 ± 0.4

These were calculated from the core regions of each phase, excluding the interfacial regions. The uncertainty values are taken from dividing the LSM phase into 7 regions and the SDC phase into 30 regions and taking the standard deviations of the compositions from each of the individual regions.
