Samarski

Samarskite, a mineral) Discovered spectroscopically by its sharp absorption lines in 1879 by Lecoq de Boisbaudran in the mineral samarskite, named in honor of a Russian mine official. Col Samarski. [Pg.185]

Samarium - the atomic number is 62 and the chemical symbol is Sm. The name derives from the mineral Samarskite, in which it was found and which had been named for Colonel von Samarski , a Russian mine official. It was originally discovered in 1878 by the Swiss chemist Marc Delafontaine, who called it decipium. It was also discovered by the French chemist Paul-Emile Lecoq de Boisbaudran in 1879. In 1881, Delafontaine determined that his decipium could be resolved into two elements, one of which was identical to Boisbaudran s samarium. In 1901, the French chemist Eugene-Anatole Demar9ay showed that this samarium earth also contained europium. [Pg.18]

Using a spectrometer in 1853, Jean Charles-GaUisard de Marignac (1817—1894) suspected that dydimia was a mixture of yet-to-be-discovered elements. However, it was not until 1879 that Paul-Emile Locoq de Boisbaudran (1838—1912), using a difficult chemical fractionation process, discovered samarium in a sample of samarskite, calling it samarium after the mineral, which was named for a Russian mine official. Colonel von Samarski. Samarskite ore is found where didymia is found. Didymia ( twins ) was the original name given to a combination of the two rare-earths (praseodymium and neodymium) before they were separated and identified. [Pg.288]

It should be emphasized that averaging technique does not require the grid to be small compared to the layering. These results can be considered as an outgrowth of the integro-interpolation finite-difference schemes. This term first appeared in the Russian literature in the papers of Tikhonov and Samarsky in the 1960 s (in Western literature the closest related technique is called the external approximation). However, only conformal variations of conductivity were treated in the classical integro-interpolation method. [Pg.631]

By some reports gadolinium was the first element named for a person, but it was probably really named for the mineral that contained gadolinia, and the mineral was named for Johan Gadolin. By the same token samarium was named for the mineral samarskite, which had been named in honor of a Russian mine official. Colonel Samarski. It is difficult therefore to assert that the name gadolinium was meant to immortalize the chemist any more than the name samarium was meant to immortalize military personnel. What was unique about samarium however was its discovery using a new analytical technique spectroscopy. [Pg.262]
