General description

Praseodymium(III) nitrate hexahydrate iscommonly used in the production of electronic components, including ceramiccapacitors, magnetic bubble memories, and photochromic glass. Its uniqueoptical and electrical properties, such as its high dielectric constant andrefractive index, make it a desirable material in the electronics industry. Itis also used as a praseodymium source for the preparation of other praseodymiumcompounds.

Application

Praseodymium(III) nitrate hexahydrate can be used as:
  • A dopant to fabricate dye-sensitized solar cells. The addition of rare earth enhances the power conversion efficiency of solar cells by narrowing the band gap of photoanode materials.
  • A precursor to synthesize high entropy lanthanide oxysulfides ( wide band gap semiconductors).
  • To synthesize functionalized UV-emitting nanocomposite for photodynamic cancer therapy.
  • To fabricate Pr-doped MoO3 thinfilms for gas sensing applications.

Innovation in dental restorative materials is driven by the need for biocompatible and natural-appearing restoration alternatives. Conventional dental materials like amalgam and composite resins have inherent disadvantages.

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.
