Pulsed laser deposition (PLD) assisted fabrication of epitaxial titanium nitride (TiN) and titanium oxynitride (TiNO) thin films with noble metal-like reflectivity, large negative dielectric constant, and figure of merit.

Atomic Force Microscopy (AFM) imaging of the RuO2-water interface shows the evolution of surface water during the water oxidation reaction. This achievement is unlocked by the advancement in AFM and charged surface modeling.

The frontier challenge of oxygen evolution catalysis is to extract the molecular details of its elementary steps. We discuss how advances in spectroscopy and theory are allowing for configurations of reaction intermediates to be elucidated.
