Lutetium - Tales from the Periodic Table

Ғылым және технология

Lutetium is (thankfully) the last of the 15 lanthanide elements which we've spent the last year and three months exploring. It's a rather expensive version of many of the previous lanthanide elements, and in most applications, can be substituted by one of the more abundant (and cheaper) lanthanides we've covered earlier in this series. However, there are a couple unique uses in PET scanners and radiotherapy for metastatic prostate cancer we'll talk about.

    Bro, that glorious '80s PBS style Model of a Modern Major-General intro sold me. Just awesome. 😎

    I've also enjoyed the lanthanides. It was much more interesting than I anticipated. I originally thought I'd end up grouping several (or all) into one video. Turned out, they're all interesting! But... I'll be glad to return to the transition metals where the applications are a bit richer.

    @@ronhipschman I find Rhenium to be extremely fascinating, as it is pretty much confirmed it is the most rare elemental metal, has the highest boiling point, although some may argue tungsten. Very very dense, and resilient, with Rhenium Diboride being one of, if not the strongest materials in the world. I also find Iridium absolutely fascinating for the fact that so little of it exists on Earth, but such massive amounts of it are in meteors. Ruthenium and Osmium have very interesting properties as well. Thank you again for all you do Ron!

    There was a bit of fuss a few weeks back when some scientists reported room-temperature superconductivity in a lutetium salt under extremely high pressures. So far there are mixed results trying to reproduce it, so it wouldn't have been a good idea to include it here. I'm very skeptical, but even if it's true it doesn't sound practical. By the way, you can date really old rocks using lutetium 176/hafnium 176 dating, but, given the rarity of lutetium and the small amount of hafnium produced, it required a brand new technology to detect them.

    For those who didn't know: if you have a significant amount of lutetium, you can actually detect the radioactivity of 176Lu with a Geiger counter quite easily or even a spectrometer as 176Lu also emits several gamma rays of different energies in addition to beta particles. Thankfully the actinides are much more fascinating than their upper lanthanide neighbors (not counting those beyond fermium which can't be produced in macroscopic quantities) due to their nuclear related applications.

    @@ronhipschman Californium is also used as a neutron source. Generally, all the even-numbered elements from 84 to 98 have some use, but the odd-numbered ones don't have much in the way of uses except for americium. Finding a use for Francium is a real challenge.
