 Crystal growth, structure determination by X-ray and neutron diffraction, and thermal analysis are also important aspects of Dr. Haile's research.The group showed for example, that a broad range of proton containing solids undergo a monoclinic to cubic transition that is accompanied by an increase in conductivity of several orders of magnitude.In another example, her group demonstrated that Ba0.5Sr0.5Co0.8Fe0.2O3-d has exceptional activity as a cathode for ceria-based solid oxide fuel cells.
