FY21 Research Highlights

I’m pleased to share our research highlights from Fiscal Year 2021, resulting from extensive collaborations both within and outside PNNL. Among our many studies, we examined order-disorder processes in oxides, shed light on catalytic behavior in superlattices, studied defect pathways for oxygen migration, and charted a roadmap for the future of electron microscopy. We look forward to sharing more of our research over the coming year!
