By varying the A-site element of the material, we can tune oxygen vacancy formation which will be investigated by PDF. The pXRD measurements will allow us to characterise exsolution kinetics. These two experiments will give valuable insight into the material's properties and facilitate an intelligent design approach for novel catalysts and energy materials
