As an alternative to single crystal silicon photovoltaics, thin film solar cells have been
extensively explored for miniaturized cost-effective photovoltaic systems. Though the fight to …

The slow activity of cathode materials is one of the most significant barriers to realizing the
operation of solid oxide fuel cells below 500° C. Here we report a niobium and tantalum co …

Superionic conductors are compounds that exhibit exceptionally high values of ionic
conductivity within the solid state. Indeed, their conductivities often reach values of the order …

Over the past decade, many efforts have been made to develop new materials exhibiting
high oxide ion mobility at low temperature. In addition to the improvements of existing …

The role of the perovskite lattice oxygen in the oxygen evolution reaction (OER) is
systematically studied in the PrBaCo2O5+ δ family. The reduced number of …

To better understand thermal strain in electrochemical ceramics, the temperature and
