description:
	This experiment is an attempt to develop further anomalous USAXS studies of the triple phase boundaries in mixed oxide membranes close to the electrochemically active interface. We wish to separate void populations that interface with the electron- and ion-conducting phases as a function of posiition and service/fabrication conditions.

Anisotropy is found close to the interface and we speculate that different anisotrpies may apply for the different void components. Thus, SR-USAXS and anomalous SR-USAXS studies are proposed on a select group of test materials.
