Periodic Videos inspired me to re-learn chemistry at the age of 36, even leading to two Org Chem college courses. Five years later, I’m still excited to see a periodic video released!
I've got a practical this afternoon where we are making the Y-123 superconductor, what a great insight into the history and other application of this element. Thank you for this excellent video!
Regarding Prussian Blue (mentioned by the Professor at 10:20) it has mechanical properties as a consistant ultra fine granule. It's used for marking up and fitting of highly precise mechanical assemblies to within tollerances of 0.001mm or less. Very usefull pigment.
There's also talk of using it as a cathode in Sodium-ion batteries, which could be a much less resource intensive alternative to Lithium-Ion batteries.
Fascinating. As a painter, I'll be looking out for that intriguing new pigment: *YlnMn Blue.* You could do an entire episode on all the *_Toxic_* substances that have been put into paints over the years. Some remarkably poisonous - even lethal - *Elements* & *Compounds* have been used to make *_Paint Pigments._* With *_Radioactive Elements_* like: • *Radium* _(Luminescent Blue)_ & • *Uranium* _(Bright Yellows & Oranges),_ as well as nastily *_Toxic_* ones like: • *Lead* _(Greys & Whites)_ & • *Cadmium* _(Bright Yellows & Oranges)_ each being very popular in their time - at least, until how very dangerous to human life they were. Among the common - yet toxic - paint compounds, is one that I'd very much like you to discuss as chemists: *Phthalates.* • What is a *Phthalate?* • What are their negative health consequences? • Why are they still so ubiquitous, when then they can cause such nasty health effects?
Cadmium-based pigments are used in tattoo "inks" -- which aren't really inks. Countless people are injecting industrial-grade pigments into their largest organ. (But they only eat "organic.")
The pigment was sold for a while by an Australian complany as "Oregon Blue YInMn", at the bargain price of $180 per 40ml. Unfortunately, it has been unavailable for the past couple of years. With some luck, there will be a new supplier soon. The price is unlikely to be lower. But from what I've heard, the pigment has some very nice properties.
@@hobbified Three tips tho: 1. Gotta be fast. Can't allow it to be buried before it gets popular 2. Gotta be relevant. Make it about the video. 3. Gotta be witty. Make lots of people laugh or go wow.
I wrote a report in 3rd grade about Yttrium, back in 1986. I've been obsessed with it since. Thank you for finally giving it proper coverage, 10 year me is rejoicing inside. :)
"I found yttrium interesting..." is a great way to say "That stuff is levitating!" I have to agree though, yttrium is even more fascinating than I expected.
I visited Ytterby this summer 2022 and visited the old mine. (it's not very well signposted) I was able to find some quartz and some ore which I now display in my students classroom in Papua New Guinea. I always enjoy and learn from these Periodic Videos. Thank You.
Every time PV posts a new video, I feel like an excited 8 year old getting a surprise present. The humility and inexhaustable enthusiasm that the professor and the team exhibit is just so infectious!
Nine, 9, elements have their discoveries tracing back to Ytterby: Erbium, Terbium, Yttrium, Ytterbium, Scandium, Holmium, Thulium, Gadolinium and Tantalum. (at least according to my old high-school chemistry-books, Swedish...)
The statement should probably have been that four elements are named after Ytterby (the first four from your list). (The next three also have geographic etymologies referring indirectly to their source at Ytterby).
If you enjoy that, you should try "Tale of the Seven Elements" a book on the least-known elements which is fascinating. The audiobook is also available, and quite relaxing as well.
Thank you Periodic Table of Videos for reminding me of my youthful love of chemistry. I had a wonderful high school chemistry teacher who was able to spark a love of chemical reactions in our stubborn heads. Professor you remind me of Mr. Runnel and I say thank you to such wonderful teachers.
There are very few channels here on RUclips that awake such a happiness in me as this one. Every time I see a new video I let go of whatever I do to watch it. I love you all so much. Thank you for your work.
I use Prussian Blue all the time as I make art using the Cyanotype process - very simple to use, but would love to see a chemical explanation by the Prof of the precise effect of UV light on the reactants.
Fe(III) is reduced by citrate in the presence of UV light to Fe(II). Oxalate and tartrate are also capable of reducing Fe(III). With oxalate reaction proceed as follows: Action of UV light on oxalate produce electrons and radicals: (C2O4)2- + hν → (C2O4∙)- + e- (C2O4∙)- → CO2 + (CO2∙)- These electrons and radicals than reduce Fe(III) to Fe(II): Fe3+ + e- → Fe2+ Fe3+ + (CO2∙)- → Fe2+ + CO2 Fe(II) which is formed in this reaction than react with ferrocyanide to produce prussian blue.
Delighted to find Sir Martyn and his colleagues once again posting their entertaining and informative "elemental" videos. From the days of my first chemistry-set over 60 years ago, I have been fascinated with the elements and their chemical reactions. These videos not only inspire me to relive (only vicariously, of course) those long ago experiments, but have also introduced me to quite a few new elements, their reactions, and their uses. Many, many thanks!!🙂🙂
Also used in growing crystals, I had to repair a solid state NdYag laser at one of my old jobs. And i used to work for a company that made artificial diamonds for industrial purposes and know it was one of the ingredients. I just worked on keeping the induction furnaces running, so i wasn't privy to what went into the mix
There was a time that I specifically use YInMn blue's hex triplet (or one of it, different sources say different triplets) just because I find the discovery very cool.
Absolutely love the demonstration of the superconductor levitating on the magnetic track. In undergrad my department had a version of that, except the track was in the form of a mobius strip! So you could set the superconductor flying and watch it cover the entire surface, "both sides", of the track.
Didn't really know much about yttrium until now. Neat stuff. Only experience I had with yttrium was a sr-90 source we had in a lab in grad school. You see, sr-90 decays into y-90, and since the half life of y-90 is considerably shorter than sr-90 the isotopes are in secular equilibrium. It was those y-90 betas you had to be extra careful about. Sr-90 betas have a max energy about 540 Kev, but those y-90 betas have a whopping max energy of 2.2 MeV!
thank you for posting great content and spreading chemistry to people in the whole world, i discovered thi channel yesterday doing some research for a university task and all of those 13 years of content made me rethink about chemistry as a whole.
This man is like a cartoon character I love him so much. This channel has somehow managed to interest me in a subject I've hated my entire educational career.
All my chemistry teachers were either hard to understand(way too strong accents), bad teachers(just reading off powerpoints,etc.), or so monotone everyone would fall asleep. Or multiple of above. The labs were always way more fun. He does remind me of those lab teachers
If I am nor mistaken Yttrium is also used in the production of certain glass fibres for laser applications. Makes the total internal reflection guaranteed. Because any leaking of the beam is bad when one works with continuous kilowatt lasers.
I was so very excited to discover this new video this morning. I enjoyed it immensely. Professor, I would've have never skipped chemistry class if your were the instructor.
I've seen superconductor maglev videos many times, but unless there's a practical application for this that would make it everyday reality, it will probably never cease to amaze me. The best bit about this is, when you take a suspended object and position it somewhere else in the magnetic field and it just stays there instead.
Yah, for lots of applications, the benefits from using a superconductor are offset by having to keep it cold enough to superconduct. But who knows, higher temperature superconductors keep getting discovered. Even some room-temperature superconductors have been discovered, though as yet they're all compounds that can only exist under millions of atmospheres of pressure.
That super conductor effect is probably the most magical feeling thing I have seen no matter how many times I see it or how much it is explained to me.
This was a really cool video - I've seen videos of yttrium superconductors before, but I never knew of YInMn Blue before. That's such an interesting composition to make a pigment!
Makes me arbitrarily proud to be an Oregonian. Thanks guys! If theres one science I'm the dumbest in, its chemistry. So you're expertise on the subject is always mind blowing. I wish science was made this interesting as a kid. You guys are exciting the next generation of heros
Yttrium also gets used in Yttrium-Iron-Garnet filters, where a small pellet of it is held in a magnetic field with RF transmission lines adjacent to it, and it can make a filter with an extremely wide tuning range, by adjusting the strength of the magnetic field to change where it is tuned. This gets used with an oscillator circuit and made its way into a lot of RF test equipment as YIG oscillators, where you may need an oscillator that can sweep across many GHz. Not common to everyone, but everyday use for a lot of people developing the stuff that is commonly used by everyone.
Yttrium is an element I've never heard about 20 years ago, but now it's showing up all the time when you're looking into new materials being developed for all kinds of uses.
I love how, other channels would have been Super Excited about YInMn Blue, or even the super conductive magnetism; but Periodic Videos gives us low-key, matter of fact narration. A smile, but low-key.
Just want to let you know that everyday my chemistry professor puts on one of your videos every day. It's pretty entertaining and great to engage everyone in the morning!
I just got a sample of pure yttrium metal very recently so it was quite the surprise when not a not so I get a new periodic video but it’s also about an element which I can touch!
My old man works in the pharmaceutical industry and he mentioned something about using a radioisotope of yttrium, Y-99, as a form of radiotherapy for certain cancers. I believe the patient is injected in the site of the tumour with a radioisotope of a higher element but when it decays to Y-99 the tumour cells are more likely to take it up than healthy cells upon where they are ionised and killed, while damage to healthy tissue is minimized.
"which is pretty indestructible" Artist: "Lets see what happens, if we put in on canvas!" Physicist: "Lets see what happens, if put it into this setup." Chemist: "Lets see what happens, if we put it in acid."
An idea for a Periodic Videos movie… Perhaps the Professor can go over the elements one by one and mention a an attribute unique to that one element? That could be cool. Thanks for everything 👍
It's smack in the middle of the 3rd group, it exists as a physical lump of metal, has real world applications, and it's less known by most people than some exotic stuff like unbipentium. Top 10 most underrated element.
8:16 It is absolutely amazing to see the levitating effect this compound has due to it being a superconductor under the specific properties. Imagine that this was the future for flying vehicles haha.
Another practical application of Yttrium is in high frequency tunable oscillators and filters. Yttrium Iron Garnet (YIG) is influenced by a magnetic field to adjust the frequency of these devices. YIG tuned oscillators and filters show up in high end radio frequency test equipment, old radar and electronic countermeasures equipment.
Yttrium is also used as a phosphor in those old style filament-like white LED lights. The LED sends out high energy blue light, and the yellowish yttrium cake absorbs and releases it in multiple energy stages. That's why those lights keep on glowing for a fraction of a second after turning the light off.
I'm the Neil (but for physics) at a local high school. We don't have any purpose for superconductor demonstration material, but every time i see floating superconductor trains, i have to do my very best to not waste (because we don't teach anything in depth about superconductors) half a semester's budget on a very cool toy train and dewers full of liquid nitrogen.
At about 7:40 there are dark (cool) magnets under and behind the vehicle and it looked like a reflection trailing it, but also might be just cooled by the vapor. Fascinating stuff!
I recently learned about thermal barrier coatings made of Yttria-stabilized ZrO2. Would be interesting to learn a bit more about these materials, too! It's not rocket science :) OK maybe it is.
@@demoaccount2392 The Raptor 2 engine has some thermal barrier coating inside, too. Unfortunately we don't know the exact type and composition, but I'm amazed by the extreme amount of bright light coming out of those engines when they're running. It has to be related to that coating, or even perhaps owed to rare earth constituents of it, much like a Nernst lamp. Seems like a topic worth another video on rare earth oxides altogether.
I made some yttrium superconductors at ECU (East Carolina University, Greenville, NC) over 30 years ago. I still have them in a bottle around here somewhere. (there's a bit of contamination in them as they don't become SC until around 90K.) There was another formulation that made a yellow flaky superconductor (looked like yellow mica), but I don't remember what it was. This would've been in the late 80's. It's a small miracle since we were using stocks from the 20's. (As a side note, a lot of things become superconductors if you have liquid helium. :-) ~4K)
Oregon State represent! I remember hearing about the blue pigment a few years ago. Pretty rad stuff. If I remember correctly, another thing that makes the new blue pigment special is it's considered relatively safe for use, which is unique for a blue pigment? I could be wrong.
Professor, you’re a world treasure and truly an inspiration for students who are striving to pursue a career in science 🧬
Yes 🙌 Yes
yes
Yes.
Well said Andre!
Thank you
It's nice to see these updates on the elements. There's always something new to discover with chemistry (and the other branches of science, of course)
That's so true! I watched the originals in my highschool chemistry classes and I'm now actually using my science degree for work!
Periodic Videos inspired me to re-learn chemistry at the age of 36, even leading to two Org Chem college courses. Five years later, I’m still excited to see a periodic video released!
I've got a practical this afternoon where we are making the Y-123 superconductor, what a great insight into the history and other application of this element. Thank you for this excellent video!
How did your practical go?!
Even behind the mask, you can see the pure joy of Professor Poliakoff watching the train levitating. This channel is such an inspiration to all!
I can't actually.
It's pretty sad seeing a mask on him. For a moment it was if the modern world hadn't caught up with him yet.
Regarding Prussian Blue (mentioned by the Professor at 10:20) it has mechanical properties as a consistant ultra fine granule. It's used for marking up and fitting of highly precise mechanical assemblies to within tollerances of 0.001mm or less.
Very usefull pigment.
Oh, right, like when precision scraping steel surfaces.
There's also talk of using it as a cathode in Sodium-ion batteries, which could be a much less resource intensive alternative to Lithium-Ion batteries.
Is this what is called engineers blue I remember using as an apprentice?
It is because it is colloidal in nature in the preparation used in "engineers blue" and provides sub-micron pigment layer.
Prussian Blue is also medically used to treat radioactive cesium and thallium poisoning, as well as non-radioactive thallium poisoning.
Just noticed the cards on the bookshelf.
I am sorry for your loss and would like to thank you for sharing it.
Fascinating. As a painter, I'll be looking out for that intriguing new pigment: *YlnMn Blue.*
You could do an entire episode on all the *_Toxic_* substances that have been put into paints over the years. Some remarkably poisonous - even lethal - *Elements* & *Compounds* have been used to make *_Paint Pigments._*
With *_Radioactive Elements_* like:
• *Radium* _(Luminescent Blue)_ &
• *Uranium* _(Bright Yellows & Oranges),_
as well as nastily *_Toxic_* ones like:
• *Lead* _(Greys & Whites)_ &
• *Cadmium* _(Bright Yellows & Oranges)_
each being very popular in their time - at least, until how very dangerous to human life they were.
Among the common - yet toxic - paint compounds, is one that I'd very much like you to discuss as chemists: *Phthalates.*
• What is a *Phthalate?*
• What are their negative health consequences?
• Why are they still so ubiquitous, when then they can cause such nasty health effects?
This be a great video for them to make.
There were also a lot of arsenic-based paints in the 19th century, as I recall. (Scheele's green -- I just watched the arsenic video.)
@@beeble2003 Another popular arsenic-based pigment was Paris green. A lot of it was sold as insecticide - and it did very well in that application.
Cadmium-based pigments are used in tattoo "inks" -- which aren't really inks. Countless people are injecting industrial-grade pigments into their largest organ. (But they only eat "organic.")
The pigment was sold for a while by an Australian complany as "Oregon Blue YInMn", at the bargain price of $180 per 40ml. Unfortunately, it has been unavailable for the past couple of years.

“Neil and Brady got real excited”, meanwhile the professor is all like “ah yes, superconducting magnets, how quaint“.

At about 7:40 there are dark (cool) magnets under and behind the vehicle and it looked like a reflection trailing it, but also might be just cooled by the vapor. Fascinating stuff!
I recently learned about thermal barrier coatings made of Yttria-stabilized ZrO2. Would be interesting to learn a bit more about these materials, too! It's not rocket science :)
OK maybe it is.
It is not rocket science but it is jet engine science, they are used as tbc coating on turbine blades to prevent them from melting.
@@demoaccount2392 The Raptor 2 engine has some thermal barrier coating inside, too. Unfortunately we don't know the exact type and composition, but I'm amazed by the extreme amount of bright light coming out of those engines when they're running. It has to be related to that coating, or even perhaps owed to rare earth constituents of it, much like a Nernst lamp. Seems like a topic worth another video on rare earth oxides altogether.

Always great videos!
Absolutely adore this channel . Thank you so much
Love the faces when playing with the superconductor wagon LOL
very interesting, nice demo with the superconducting train, all trains should have super conductors
I had a Y90 Radioembolization on my liver 3 years ago and is working well on my liver tumor ... great discovery !!!
yimin blue pigment is so pretty, what a wonderful discovery.
I made some yttrium superconductors at ECU (East Carolina University, Greenville, NC) over 30 years ago. I still have them in a bottle around here somewhere. (there's a bit of contamination in them as they don't become SC until around 90K.) There was another formulation that made a yellow flaky superconductor (looked like yellow mica), but I don't remember what it was. This would've been in the late 80's. It's a small miracle since we were using stocks from the 20's.
(As a side note, a lot of things become superconductors if you have liquid helium. :-) ~4K)
Friedrich Wöhler: "Yeah so basically I discovered two new elements, anyway they're kinda cool I guess."
The world: "Ok."
Oregon State represent! I remember hearing about the blue pigment a few years ago. Pretty rad stuff. If I remember correctly, another thing that makes the new blue pigment special is it's considered relatively safe for use, which is unique for a blue pigment? I could be wrong.
