1. 47:24; Caducity - Vision for the Morrigan / Praseodymium

2. Silicate crystals doped with praseodymium ions have been used to slow a light pulse down to a few hundred meters per second.

3. Praseodymium alloyed with nickel (PrNi5) has such a strong magnetocaloric effect that it has allowed scientists to approach within one thousandth of a degree of absolute zero.

4. Complexometric determinations of praseodymium, neodymium and samarium as representative members of the rare earths with Alizarin Red S, Thoron, and Murexide as ohelatochrome indicators have been investigated.

5. 8 In 2008 the company introduced a new barter terms of trade, which increased sales revenue and profits, also strengthened the company's praseodymium neodymium oxide control of the market.

6. Conductances, transference numbers and activity coefficients of some rare earth halides Abstract The Conductances, transference numbers and activity coefficients of aqueous sblutions at 25.0°C of lanthanum, praseodymium, neodymium, gadolinium and erbium bromides and of gadolinium chloride were determined for concentrations up to 0.1 normal.
