Application

Samarium(III) nitrate hexahydrate is a Lewis acid catalyst that is used in the synthesis of a variety of materials for applications such as:
  • synthesis of nitrate precursor solution which can be used as a nanocatalyst in the solid oxide regenerative fuel cells.
  • for the formation of coumarin derivative by von Pechmann condensation of phenol with ethyl acetoacetate in the presence of samarium complex as catalyst.
  • for the preparation of samarium doped ceria, which can be used in the fabrication of electrolyte for fuel cells.

The Rare Earth Crisis—The Supply/Demand Situation for 2010–2015

The rare earth elements impact nearly everyone in the world. All of the people living in advanced technological countries and almost all those living in third world countries utilize the rare earths in their everyday living—the car that one drives (gasoline is refined from oil using rare earth catalysts and catalytic converters reduce the polluting emissions from the automotive exhaust), watching the news on TV (the red and green colors in TV screens), the telephones and computers we use to communicate (the permanent magnets in speakers and disc drives), just to name a few examples.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
