If you are curious, here are our first Scandium videos...
Scandium version 2: • Scandium (version 2) -...
Scandium version 1: • Scandium (version 1) -...
I loved the Mike Rumsey segment! I love all the chemistry too, but seeing how it is in the natural form ties it together. From mineral to metal to chemistry!
16 years on UA-cam and still going 👍 ... Thanks to the whole team, before and behind the camera.
Yep we are gratefull🎉
i literally grew up with it XD. Was O levels student, now Postdoc in Materials Science! AlScN is probably the hottest area you will see Sc
"we finally got ahold of a bunch of scandium, what do we do with it?" "Burn it, of course!"
The mark of a true scientist
3:26 Neil is jacked 😧
Almost as hard as his nerves, he barely blinked when it caught light
Fam, stone cold. “I been here before”…
@@matewis1 professionalism at it's finest.
The Chemical Stig.
this channel never gets old
Whoever does the very subtle soundtracks to these videos is doing a great job
Protect Prof at all costs
Neil is an absolute unit
I believe you mean goat🐐😊
Science rests on his shoulders
“Hench” is the term I believe.
4:20 Even when there's a bright flash and fire at less than arm's length from his face, Neil has the same expression.
I bet even his eye pupil diameter did not change.
Never get tired of watching and listening to these guys explain and predict and tinker.
4:23 Neil causes Scandium to flinch, and not the other way around
Neil was like stone
A truly great episode! Seeing the mineral form and how rare Scandium is added great context.
Outside of a few highly exotic aerospace alloys, largely experimental solid electrolyte fuel cells, high color rendering index metal halide lamps, and erbium dental lasers, scandium still has practically no uses. Even the latter two applications are disappearing due to LED adoption and simpler erbium YAG lasers that don't contain any scandium, respectively. Barely 20 tons of it is used each year world wide. Compare to its next door neighbor titanium at a relatively huge 230,000 tons per year, or even neodymium at 60,000 tons! Even bismuth which is 3,000 times rarer in the Earth's crust has a yearly production of about 20,000 tons, a thousand times greater than scandium.
Bismuth might be overall rarer in the whole Earth's crust, but more concentrated at some places or is a byproduct when mining for other elements, therefore it is much cheaper to produce. Scandium is very expensive to produce and it's properties are not special enough that it can't be replaced with other materials, so it isn't widely used.
I thought this could be part 3 of a 21-part series, one for each proton! Plus the isotopes as a bonus!
Could watch these all day! 🙂 Thanks Team-PV
This is a brilliant revision of the Scandium video. Really loved the burning filings - it's just beautiful.
Also thanks for the French practice at 8:10
Great to see you back professor !
I inherited a scandium frame revolver from my gramps. it is shockingly light! from what i understand, the frame is milled from a solid chunk of scandium and a steel sleeve is insert into the barrel to handle the pressures
The principal commercial use of scandium in the US used to be white metal halide arc lamps which were based on a mixture of sodium and scandium halides. I believe that European manufacturers used a different chemistry based on indium and dysprosium, although I don't know why.
I love these videos. Please keep making them. I do notice, from time to time, a technical issue with the camera work. At times, when Martin is being filmed the background book shelves are in perfect focus, but he is not. I wonder if the autofocus settings are wrong.
That ignited and burned very fast and bright, must have been a impressive energy release.
love the jane street ad. whoever set that up is a marketing genius
Great to see the series continue.
A question though: is there any unique property of scandium?
Or in other words, is there any application of it which absolutely requires it rather than any other element?
That super slow mo shot was so beautiful
Lets hope more elements are discovered so that this channel can keep going!
I’m waiting for the island of stability.
Probably arrive the same time as controlled fusion. 😂
Hello, thank you very much for these chemistry videos. Super!
Sincerely, Antonio Constantin🙂
I keep seeing (new) and I'm like wow finally a new element
The professor's head appears in the scandium solution at 3:03!
Finally we get to hear Neill's voice! "Yep?"
Thank you for all the brilliance you have shared with us.
Professor Poliakov's been de-floofed 😂😂😂
Very nice video. I would like to know what scandium is used in/for?
Many things, although it's not as ubiquetous as e.g vanadium or chromium. One application I like is weldable high-strength aluminium-scandium alloys. These are used e.g in the Airbus A380 airframe.
4:07
Neil did not even blink.
A phenomenal video!
I wonder if you grind it does it self ignite to make sparks?
I used to work with a lot of scandium oxide.....it was a very nice material for nanomaterials. I was able to tune the fractal iteration of these little plates id make
Thank god for the geologist because I was sure there was a blue mineral of scandium, be interesting to try and grow a much larger crystal
Would have been nice to see a spectral analysis
Interesting as always!
Beautiful mineral samples 😃
The reaction with bromine could have been hampered by a surface layer of oxide. Should have tried it with freshly cleaned surface, like the one after Neil did the filings.
The dark surface could possibly be due to etching by the bromine water.
At some point you should maybe change from using the New-new version to using maybe the year instead. 😂
500 piece puzzle in background - it must be done! :D
Science is so fkin cool
The density of Sc is only 10% higher than Al. I believe they tried to make bike frames from it.
So in principle you *_can_* make a Scandium sparkler, but the rich don't know what it is, and nobody else can afford it ... except possibly a chemistry lab on a university.
the boys are having fun in the lab
Sure they are
Running the advert for a quantiative trading firm at the end was where the video turned towards a dark side for me. :)
I have a S&W 329 revolver made with Scandium alloy frame to be lighter weight. Interesting metal.
4:19 Just watching Neil stare at that flash makes MY eyes hurt. 🔥 👀
Can y'all do a quick video on the conductivity of hardened tree sap. I made a battery out of crushed pearls and the usual minerals encased in amber and it is taking forever to lose charge.
Nice 👍
9:50 Feldspar ::)
What about the practical uses of scandium? Seems like a huge area of interest that was missed. Still informative and enjoyable though.

Ahh Neil never change
Yess a new PT video!
Neil looks a villain from Indiana Jones
The black colour on the scandium might just be microscopic pitting from reacting with water/bromine.
Doesn't Neil worry about melting his gloves in the bunsen burner??
He doesn't worry because he knows what he's doing from years of experience.
That's scand -ium- alous 13:07
That's the only time I've ever seen Neil speak.
PROFESSOR!!!!!!!!!!!
These bothans is madlads, innit??
"I have no idea, if there is we haven't found it yet" is the correct answer.
A chemist with a strong grasp of nucleosynthesis would have an idea, at least. This is one of those interesting questions that requires knowledge across both chemistry and geology. The second part of the answer remains the same, unfortunately.
How do you know? And why are you implying that he would lie?
That's a scandalous amount of Scandium!
🥰
Hey Professor!
Salve my heart!
Nice
Welcome back
OMG HEY PROFESSOR!
what are all these brainless comments... did periodic video advertise the new video on tiktok or something?
Should contact smith and Wesson they make revolvers out of scandium
You really got Sc worth 20000€ 🤔
Actually, i'm your anomaly apparantly.......
❤️🔥🫂❤️🔥
Thotvetite 😂
Cool Science and Imma1st
Don't take my comments seriously. It's only a meme
4:54 gotta be careful using that phrasing. Nearly had a heart attack thinking you'd caved to some skeevy sponsor to hawk their trash.
”But before I tell you about the result, let me tell you about my new favorite game: RAID: Shadow Legends.”
Lol I was thinking the exact same thing 😅
Been waiting on this one
Greattttt
FIRST!
TRUMP 2024
Ignus.
Fdjt
F djt
We finally got the video on scandium.
Was looking forward to seeing its reaction with bromine...
Keep It up👍
14:50 beautiful and hypnotic!
Love you Prof. Your first Scandal!
Hey
