About the PNAS Member Editor
Name Abruna, Hector D.
Location Cornell University
Primary Field Chemistry
 Election Citation
Abruña, a leader in electrochemistry, has revolutionized electrochemical interface understanding with pioneering methodologies (e.g., in-situ X-ray based methods TEM and differential electrochemical mass spectrometry). He has developed redox and photoactive nanometric building blocks for modifying electrode surfaces, fuel cell electrocatalysts, organic materials for batteries, and graphene as an electrochemical platform.
 Research Interests
Our research efforts take an interdisciplinary approach to the study of electrochemical phenomena. We employ electrochemical techniques as probes of a variety of chemical systems, and have developed operando methods based on X-rays, transmission electron microscopy, differential electrochemical mass spectrometry and others to address problems of electrochemical interest. Our current research interests are focused on the design, synthesis and characterization of high performance materials for fuel cells and batteries. ~We have developed highly active electrocatalysts for the oxygen reduction reaction (ORR) based on core/shell structures with ordered intermetallic cores and metallic shells and are currently exploring the development of electrocatalysts for the ORR and HOR (hydrogen oxidation reaction) in alkaline media. We have carried out extensive operando studies of Li/S batteries and have emphasized the use of organic-based materials for electrical energy storage applications.
