Cerium in a sentence

If cerium is the dominant lanthanide, then it is converted from cerium(III) to cerium(IV) and then precipitated.

Cells treated with just cerium had decreases in cell viability, but cells treated with both cerium and transferrin had more significant inhibition for cellular activity.

The relative ease with which the 4th electron can be removed in cerium and (to a lesser extent praseodymium) indicates why Ce(IV) and Pr(IV) compounds can be formed, for example CeO 2 is formed rather than Ce 2 O 3 when cerium reacts with oxygen.

This is the proposed mechanism for cerium’s effect on cancer cells, though the real mechanism may be more complex in how cerium inhibits cancer cell proliferation.

A combination of heavy and light rare earth oxides, excluding cerium and yttrium.

His team had discovered that under certain circumstances, the mechanical properties of cerium oxide – in pure form and when laced with impurities – didn’t fit the classical picture.

If saving space is a key consideration, the Arc’teryx Cerium Hoody is a much better option that’s just as warm, though not quite as durable.

Two others were North Korea’s Lazarus Group and a group Microsoft calls Cerium.

Berkelium and cerium are then separated with another round of ion-exchange treatment.

Cerium has shown results as an anti-cancer agent due to its similarities in structure and biochemistry to iron.

Cerium may bind in the place of iron on to the transferrin and then be brought into the cancer cells by transferrin-receptor mediated endocytosis.

Element substitution for the calcium cation often includes certain rare earth elements (REE), such as yttrium and cerium.

Greenwood & Earnshaw, p. 27 The electrons in the 4f-subshell, which is progressively filled from cerium (element 58) to ytterbium (element 70), are not particularly effective at shielding the increasing nuclear charge from the sub-shells further out.

In the periodic table, it appears to the right of the alkaline earth metal barium and to the left of the lanthanide cerium.

Lanthanide oxides: clockwise from top center: praseodymium, cerium, lanthanum, neodymium, samarium and gadolinium.

Lanthanum usually occurs together with cerium and the other rare earth elements.

Lanthanum was first found by the Swedish chemist Carl Gustav Mosander in 1839 as an impurity in cerium nitrate – hence the name lanthanum, from the Ancient Greek λανθάνειν (lanthanein), meaning "to lie hidden".

One of the specific elements from the lanthanide group that has been tested and used is cerium (Ce).

See, for example: citation Early techniques for chemically separating scandium, yttrium and lutetium relied on the fact that these elements occurred together in the so-called "yttrium group" whereas La and Ac occurred together in the "cerium group".

The hybridisation is believed to be at its greatest for cerium, which has the lowest melting point of all, 795 °C.
