The research on new anode materials for solid oxide fuel cell is extremely important for its potential to overcome the drawbacks of current state of the art anodes. In this...

NaNbO3 has long been regarded as the 'most complex' perovskite known, with at least seven different phases reported as a function of T, at least two of which have evaded all...

Doped cerias are currently being used as oxide ion conducting electrolyte materials in solid oxide fuel cells (SOFCs). The conduction mechanism in electrolytes is dependent on...

New superalloys with higher temperature capability are required for more efficient gas turbine engines in civil aviation. Recent research has identified that alloys with...

Sodium Bismuth Titanate, Na0.5Bi0.5TiO3 (NBT) is a mixed A-site perovskite. It is both of commercial interest, due to its usage in lead-free piezoelectric solid-solutions; and...

We are examining a number of cobalt-molybdenum carbonitrides as possible catalysts for reactions that produce nitrogen-containing organic molecules. There is good evidence that...

Increasing global population, global warming and depletion of fossil fuels have resulted in a growing need for better energy storage. Lithium-ion batteries are promising devices...
