We use two interlinked strategies for the design of new interfaces: (i) materials-by-design, which involves transferring the knowledge gained from single-crystalline materials and thin metal films to nanoscale materials; and (ii) double-layer-by-design, which exploits the precise organization of electrolyte components at the sub-nanoscale régime of the double layer.
We explore a broad range of materials and electrolytes, including metals, metal/metal-oxides, pure oxides, sulfur-based and carbon-based materials, as well as aqueous electrolytes with a wide pH range and organic solvents that are used in battery systems.
We use a diverse range of methods to study interfacial properties, including ex situ and in situ optical methods, microscopy-based structural probes, ultrahigh vacuum techniques, synchrotron-based techniques, and classical analytical and electrochemical methods.
As a group, we use a surface-science approach to understand, at the molecular and atomic level, the key energy-fuel-environmental cycles that constitute the core building blocks for efficient, green and viable energy production and utilization. Our central aim is to provide a critical assessment of unifying characteristics that govern the activity, stability and selectivity of electrochemical interfaces.
