ytterbium

I mean, sure, how can you expect to live a normal middle-class lifestyle without a few hundred tons of ytterbium?

Also, one of the more interesting things to me is that ytterbium, for example, has a half-life which is measured in days.

Is this (the OT [1]) with ytterbium a more or less efficient way to count clock ticks with high precision than is described in [2]?

Rare earths are elements like lanthanum or ytterbium.

As for Ytterbium - since there doesn't seem to be any stainless steel (SS) alloy for sale or even described / designated a code, it was possibly a one off project.

In this case the laser produces infrared light in the same band as the lasers used for optical fiber communications, and it is based on glass doped with erbium and ytterbium.

Or its cousins, ytterbium, terbium, and erbium, all of which were first refined out of an obscure mineral, ytterbite, and all named with a stunning deficit of creativity.

I'm paying hundreds of dollars to sit in your lowest-bid Metal Death Tube or stay in your Totally Not A Bedbug Sanctuary, stop treating me like a transient who walked into a Rodeo Drive boutique because I don't have Triple Ytterbium Status.

Why are rhenium, rhodium, lanthanum, europium, dysprosium, thulium, ytterbium, yttrium, strontium, thallium, magnesium and manganese so irreplacable?

What is important is that for such a frequency/wavelength it is possible to build laser sources, which enables the design of an atomic clock that will use thorium 229 nuclei instead of neutral atoms or ions of other elements (like ytterbium, lutetium, strontium, aluminum).

When the first high-temperature semiconductor has been discovered, the team which did it has intentionally misspelled in their published research the element name yttrium as ytterbium, in order to fool everybody who will try to replicate the research, but to still allow themselves to claim that they have priority in publishing, but they have just made a honest spelling mistake in their published paper.

The latest 'atomic' clock uses "spin-polarized, ultracold atomic ytterbium".

It's said that "Ytterbium (Yb) is sometimes alloyed with stainless steel to improve its mechanical properties, such as strength and durability." This claim has been repeated 1000 times.

Ytterbium: Miniscule vitrified sampled are bombarded by lasers as the time keeping component in high quality atomic clocks.

Ytterbium used to be (carefully) splattered all over the screen of every color TV, to fluoresce red.

Ytterbium (Yb): stainless steel, lasers 15.
