Not exact matches

Spanning 17 elements — from lanthanum to lutetium, plus scandium and yttrium — they find use in computers, screens, superconductors, oil refineries, hybrid or electric vehicles, catalytic converters, compact fluorescent lightbulbs, light - emitting diodes, lasers, audio speakers and microphones, cell phones, MRI machines, telecommunications, battery electrodes, advanced weapons systems, polished glass, and even the electric motors that run automobile windows.

BMGs are metal alloys composed typically of three or more elements, such as magnesium, copper, and yttrium (Mg - Cu - Y).

BOTTOM: Introducing a third element with a dramatically different atomic radius, in this case large yttrium atoms (yellow spheres), frustrates the alloy's tendency to crystallize, so it solidifies in a random, or amorphous, pattern similar to that of glass.

Researchers from the KU Leuven Department of Chemical Engineering have discovered a method to separate two rare earth elements — europium and yttrium — with UV light instead of with traditional solvents.

Professor Park Je - Geun, Associate Director of the Center for Correlated Electron Systems (CCES), within the Institute for Basic Science (IBS), and colleagues have observed, quantified and created a new theoretical model of the coupling of two forms of collective atomic excitation, known as magnons and phonons in crystals of the antiferromagnet manganite (Y, Lu) MnO3, a mineral made of manganese oxide and rare - earth elements called yttrium (Y) and lutetium (Lu).

In 1794 Gadolin concluded that the specimen contained an entirely new element, later named yttrium.

Elements were frequently named for the town or region where they were discovered, sometimes in a very provincial manner, as was the case with yttrium.

Rare - earth elements include scandium, yttrium and the 15 lanthanides found towards the bottom of the periodic table.

Studying the spectra of the stars, the researchers found unexpectedly high abundances of the heavy elements strontium (Sr) and yttrium (Y).

The latter stars exhibit weak helium lines, low rotational velocities, and excess amounts of gallium, strontium, yttrium, mercury, and platinum, as well as absences of such elements as aluminum and nickel.

Most of them elements (erbium, yttrium, cerium, lanthanum, and the component elements of didymium) belong to the family of rare earths, a group whose classification would present problems for many years to come.
