Voorbeelden van lanthanide

• The section on rare earths (lanthanides) is also notably strong.

• In this regard, the use of lanthanides provides a gamma of versatile paramagnetic probes, but still needs to be fully exploited.

• The reason for the high potency of the lanthanides is probably partly due to their trivalency.

• These series are, respectively, the lanthanides and the actinides.

• Due to the lanthanide contraction of the elements in the sixth period, zirconium and hafnium have nearly identical ionic radii.

• Lanthanide-mediated epoxidation has been successfully applied to cinnamates and -heteroaryl unsaturated esters.

• Contrary to most other lanthanides, which have a close-packed hexagonal lattice, ytterbium crystallizes in the face-centered cubic structure.

• Phosphors with lanthanide dopants are also widely used in cathode ray tube technology such as television sets.

• The lanthanides elute in order of decreasing atomic number.

• Monazite was the only significant source of commercial lanthanides until bastnsite began to be processed in about 1965.

• Because of its closed-shell electron configuration, its density and melting and boiling points differ from those of the other lanthanides.

• Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use.

• In an aqueous solution, like compounds of other late lanthanides, soluble lutetium compounds form a complex with nine water molecules.

• Other carbon rich stoichiometries are known for some lanthanides.

• About 15000 ton/year of the lanthanides are consumed as catalysts and in the production of glasses.
