Neodymium - Who really knows?

This.

It's also quite a widely used as a dopant in laser design (the system I use most frequently uses an Nd:YAG laser).




Pee-ay-zoh, though I've also heard it said said as Pee-et-zoh.

I studied Electronics at College in the 60s. It was pee et so then but that was in the UK. Who was it that said that the USA and Britain were two countries separated
by the same language?

Now repeat after me Tomato, Aluminium, Solder...,

Keep an eye on fiber lasers. Some of them put out at 1064 nm, and are scary powerful.

We've got a 1064 nm Fianium 1 Mhz, 1 Watt (continuous) fiber laser in the lab, also good fun! The aforementioned Nd:YAG (~3.5 watt), a couple 800 mW diodes at 980 nm and a slowly dying 5 kHz Ti:Sapph which is putting about about 10% the power it should be.

A mate of mine worked primarily on high power slab laser design, he built some scary death lasers, one that was several hundred watts, pulsed (μs if I remember correctly), was his baby during his PDRA.

It's not usually pronounced with the T over here, or at least where I am, these days (I'm in the UK, finishing up my PhD in Physics so work with quite a lot of Electronics folks). My father always pronounced it with a T as my grandfather (electrical engineer) used to pronounce it that way. However, I'm honestly not sure where that pronunciation originates from.

And here the correct German version ... :)

Neo-DÜM or Neo-DÜ-mi-um (the ending "ium" gets out of use).

It a Greek/Latin word.
As far as I remember, words with 4 syllables and more should be stressed at the 3rd last syllable.

I'm in a company which sells SEMs, FIB-SEMs etc. ($100.000+).
We have no YAG lasers but YAG detectors. But I'm no physicist - I "only" do the marketing, graphic works etc. (as a skilled metal worker with university experience - with ancient Greek) ...

Never heard it pronounced with the "DÜM" (that includes from Greek and German speakers) nor does it's written pronunciation anywhere seem to match that. The origins of the name in Greek come from neos didymos as it was one of two elements to be found in what was previously thought to be a single element. It was originally called Neodidymium but Welsbach (discoverer) fairly quickly renamed it Neodymium.

While it may not be correct linguistically (one could argue the name itself isn't pure Greek or Latin), it seems to be the convention with which is it pronounced, names can be funny things like that.

Sadly quite familiar with the expense of SEMs!

Hi i got a mohawk,

"60 Nd" was called Neodymium for some time. Meanwhile it was "renamed" to Neodym in Germany (which makes the use of the word much easyer) ...

I now looked at wikipedia and found both Greek origin words.
νέος (neos = new) and δίδυμος (didymos = twin / of lanthanum) ...

The "υ" ("y") in Greek words is mostly spelled "ü" in German (a pronunciation English don't have / can't do) - like Dynamo, Dynastie (dynasty) +++
In English the "υ" ("y") in Greek words is mostly spelled "ie" like "to die" > "die-na-mo", die-na-sti" ...

That's why I would write the German spelling neo-DÜm (English spelled: nay-oh-DÜM)
and in Englich knee-oh-die-me-um ...

Fair enough, I still stand by having never heard it that way though :p

The same wikipedia page also lists it as:

"NEE-o-DIM-ee-əm"


Oxford dictionary (http://oxforddictionaries.com/definition/english/neodymium?q=neodymium) lists, which isn't stressing it as an I ('eye') but an i:

/ˌniːə(ʊ)ˈdɪmɪəm/"


Dictionary online (Link Removed
):

"nee-oh-dim-ee-uhm"

Aren't they starting to use Neodymium in electric motors?

Can be used in place of old school permanent magnets in most places. Being used in motors is one of the iffy points with wind turbines, as neodymium isn't a cheap or easy element to extract, not one to extract cleanly either.
