I love these revisitations of elements that have already been covered once. It really demonstrates that no matter what we know we can always learn more. A great lesson for youth.
all of us
Neil was clearly enjoying himself with the sledgehammer. Great to see new videos and learn about the history of the various elements. I wish they taught this in school.
Fun fact from a geologist. Most rhenium is sourced from the mineral molybdenite, which is a primary ore of molybdenum that often can have a lot of inclusions of rhenium. If the weight% is high enough, we actually give it a subspecie name of rhenium molybdenite. The rhenium bearing molybdenite often occurs in porphory deposits, which contain a lot of metal sulfides, primarily of copper. One of those is in Kazakhstan, which was mentioned here, but theres also plenty in many volcanic zones, noteably in Chile, and southwestern USA/Mexico
I am disappointed it is not rhenish molybdenite, like the wine from the Rhine.
Thanks
I wonder whether the Climax molybdenum mine in Colorado has enough rhenium in the molybdenum ore to be a practical source. The ore is only about 1/6 of a percent molybdenum, so the amount of rhenium probably is vanishingly small…
A lot of people don't know this, but natural rhenium is actually slightly radioactive. It occurs as two isotopes: Re-185 and Re-187. The 185 isotope is stable, but only makes up a third of natural rhenium. The 187 isotope is the rest, but has a half-life of around 40 billion years.
I don't have this much time to wait for it to disappear. I think I'll burn my rhenium instead.
Is that Neil saying "Oops!" I think that's the first time we've been allowed to hear him.
More regular uploads please. Go beyond the periodic table, give us all the knowledge professor has to share !
When Professor Poliakoff said "so we are here at..." I thought it was going to cut to him being filmed at the volcano, Tom Scott style, despite having said he wasn't going to go.
You weren't the only one who thought that!
haha at least i'm not the only one lol
Now you missed James Burke style in his Connections series.
Every day with a new video from Professor Poliakoff is a great day.
I think that absolute unit of a vise deserves its own video.
"I think these stories are lost in the midst of time..." is such a wise way to say "I think you can make up your own mind about that"
All these new element videos are really nice.
20 minutes flew by in an instant.
It is said that during the Second Age, Dark Lord Sauron forged the One Ring with Rhenium in the fires of Mount Doom.
Fires?
I it also said that Bilbo of Shire had a chain mail of Rhenium that was brigher than silver and lighter than iron. This chain mail was forged by the Dwarves with a technology that is still unknown today and use to flabbergast both modern chemists and physicists.
I thought that was a joke until I googled it.
So that's why they find it in volcanos!
Neil was clearly enjoying himself with the sledgehammer. Great to see new videos and learn about the history of the various elements. I wish they taught this in school.
I didn't realize I was over 70% as old as the discovery of Rhenium! My first 'real' job out of high school was working as a sample preparation tech at a largish copper mine on Vancouver Island, B.C. The mine milled 30,000 tons per day of ore to produce about 600 tons of a copper sulphide concentrate which contained small amounts of gold and silver. A separate mill circuit reprocessed the copper concentrate to extract molybdenum. As a paid-for byproduct the molybdenum concentrate contained some rhenium. The copper went in bulk by ship in lots of 10s of thousands tonnes, the moly went by semitrailer truck in barrels much less frequently, and the rhenium was left up to the moly buyer to recover on their own.
Can we please have a video of the lab or maybe how the fume cabinet works and where the fumes go and how they get filtered
In most regular labs the exhaust isn’t filtered.
This is the video I needed today :) Neil's obsession with igniting powder over a bunsen burner is an inspiration to us all
You should buy Neil a diamond file for Christmas, he’ll be able to get sparkly powders from anything then!
Imma get blasted when i get home and binge watch 5 of these
I was unprepared for the phrase 'rock star' in a chemistry video. tip of the hat to you, professor.
I LOVE that you are still putting out more videos in this series! and YES, I have watched ALL OF THEM.. IN ORDER!!! :D It's a bit disappointing that there isn't much to say about quite a few of the elements... science just hasn't found a use for all of them I guess... but when you guys put out new vids like this I feel like a kid in a candy shop because it's usually about the elements you weren't able to make full videos about....
And the cool partt is that I honestly forget most of what I watched those couple of years ago, so I would be perfectly fine with watching them all over again one day :)
THANK YOU BRADY, PROFESSOR, AND NEIL (and all the supporting cast through the videos) - :)
19:35 I like that Natalia was silently watching the chemistry demonstration up-until the end where she saved the whole video by creating a fascinating fluorescent Rhenium compound.
RE: Rhenium
This element must be very important for sending e-mails...
@@LarixusSnydes underrated
Neil's office which has no windows and a bar below the ceiling from which he hangs when he needs to rest.
Loving the new versions if these!! Always good to see the crew again.
Thank You Professor, Neil and Brady and all for allowing me to be a little less ignorant regarding the elements and chemistry. Forever watching.
17:06 Is that an oops by Neil?
i briefly worked on lithiated MoO3 and WO3, the most interesting oxide materials I ever worked on. I remembered Moly's video where you guys tried evaporating a Mo wire, but formed Mo oxides which were volatile instead. Now, ReS2 formed by volcanoes? wow, very very intrigued, i love it. ReS2 is also a highly studied 2D material, if you would like a sequel on Transition metal dichalcogenides
Having done a PhD on organometallic rhenium chemistry, I must compliment you guys on the good video. The vulcanic ore was new to me, and the controversy surrounding its discovery is a funny story. Some points (however): The incineration of Re could have been done to greater effect. If Re is heated in an O2 atmosphere above 250°C (you can do so with the pellets at >50 g scale in a tube furnace), you can obtain fairly pure Re2O7 which is a volatile yellow solid. Secondly, I can confirm that mechanically manipulating Re is essentially a lost cause (Mohs hardness 7) and we have destroyed several tungsten carbide drill bits in futile attempts at obtaining Re shavings. Thirdly, the fundamental chemistry of rhenium chemistry is rather exciting, the [Re(CO)3Phen(Br)] complexes being only one of many useful compounds. While perhaps not as exciting to a larger audience, it quite exciting to work on. Cheers :)
Thank you Professor Sir Martyn Poliakoff
Thank You Brady Haran
Thank you Neil
Thank you Team
Can we get a video show casing all of the professors favorite reactions and/or elements?
Edutainment at its best.
Nobody really learns anything truly useful.
But it’s entertaining.
Wow, that yellow Rhenium substance at the end is eye-popping!
Thanks for doing a video on my favorite element!
That is a very specific green colour. Not sure I've seen anything like it elsewhere.
I was not prepared for a reference to Wyld Stallyns!!!!
Thanks for more elemental education and entertainment. Neil and his burning powders should get their own video.
18:10: the fragments were not Rhenium. Wrong color!
Soonest I've been to a video release!! :D
Vulcanism wise, you need things like a subducting mantle plates to drop almost straight down and pierce the deeper layer in a way that the deep magma is caught in an up-rush from the "void" left from the plate moving.
Not the most notable volcanic feature, it is just that denser element laden magma kinda has to squeezed-out like a frozen tube of toothpaste, the density makes it reluctant, something has to "pull it".
Probably not a feature mineral in rift valleys ever (which it obviously is not.
Slip strike faults maybe, but you'd expect a chain.
Sometimes singles like that are meteoric, not saying this is, just needs further points to exclude it that I won't guess at.
*That was sort of a mess, basically; you don't get the heavies unless some uncommon extremely deep stuff manages to get to the surface and by nature it does not want to be up here, it wants to drop. Like metallic mercury in water, takes special circumstances to get the mercury to stay on top of the water.
Oh wow, Neil's living on the edge. When he dropped that lump of very dense metal into the test tube I had expected it to shatter and spray nitric acid everywhere, the KLONK was very audible! :D
Nice to see this new video about this very beautiful element featured. A sample of Rhenium lies next to me on my desk. It was the most expensive collectible i ever bought. The density and physical properties are really fascinating. But there is one detail which should not be missed. Rhenium is radioactive. But the resulting beta rays are some of the weakest of all radioactive substances (Less than 2700 electron volts). That means that this radiation is even to weak to leave the sample of rhenium. The lack of any other radioactive isotope make it scientifically important. Beta rays are accompanied by neutrinos. Low beta energy makes the energy of the neutrinos more obvious.
I love the framing of the shot at 17:36! Tiny person underneath the angle grinder. :)
Natalia's handshake game is on point.
Always fascinating!
That rockstar joke was rad
how wonderful for the Professor and Neil to do elemental chemistry. Chemistry these days is mostly lasers and computers; this is mixing two substances together and seeing what sort of sparks fly
My friends have no idea what a high level nerd I am :) I love this stuff, 45 years after my University Chemistry courses that I never put to use.
And so today I learned a little tidbit about KGHM's business.
I want a roof top of this material. It will last forever.
The roof may last forever, but it will be very heavy. Such a roof will have a crush on a typical American house...
Why you don't go beyond the elements of the Mendeleev table, and prepare some lectures in - say - organic chemistry, hybridisation, organic synthesis, what a catalyst does, cracking and reforming, etc. You can teach some industrial applications of chemistry, i.e. how to prepare a perfume, create an ink, produce vegetable oils, or create an elastomeric glue, etc.
I'm sure there is a lot you can teach about chemistry, and you can rest assured you have a wide audience.
Greetings,
Anthony

11:22 Nice Bill & Ted reference 😂
;)
You guys are the rock stars. !!
I'd love to try that rhenium phenanthroline complex as an indicator in the Belusov-Zhaboutinsky reaction. In my lab days I worked with oscillating reactions a bit, and found a couple other redox indicators besides the traditional ferroin for the usual BZ manifestations.
Bathophenanthroline iron works fine, and I'll bet the rhenium analog would work and would be visible under UV light, the usual target patterns visible with it's yellow fluorescence - you should give it a try. (another analog would be rhenium (tris)bipyridyl for the usual ruthenium(tris)bipyridyl which is used for all sorts of things.....
Fascinating video. Thank you 😊
I would love to have all the individual elements made into wire strands and tested how they sound when played on a violin, other string instrument, or a similar test. At least for my curiosity.
Interesting idea
Ida Noddack , I bet there was a lot of lab humour related to her name.
"This is Ida Noddack"
"Well now you know"
I'm rather impressed by that brown gas. It's a really rather pleasant shade of amber to my eyes.
Beautiful and adulation video as always, I really appreciate you guys. Something always flips me out how you want to burn any chemical element. It’s almost like an obsession with arson and burn that damn element. Neal always does it. Why is that?
Last time I was this early hydrogen was the heaviest element
4:02 Not Neil wearing nitrile gloves when working with conc nitric acid, surely?!
Oh my goodness, another wonderful video!
What would have happened if the fumes from the burning rhenium were introduced to the air intake of the Bunsen burner?
I'm also curious about the weight of the rhenium pellets before and after burning. I realize they were burned in air, so we really didn't know how much oxygen was consumed, but I just get curious. (That's probably why my projects take so long to complete; I'll follow too many sidetracks.
By the way, I used my spectroscope to analyse the video flame. It was greenish. JK!
I was wondering about the possible weight changes as well.
Thanks for the video.
As you pan across the audience you see all these people and one scientist marked by that wild hair.
1:30 Um, what does molten carbon look like? 🤔
Glowing white.
@@BenAlternate-zf9nr Cool! Thanks Ben! 🙏
I wonder if Alec Steele could create an alloy or Rhenium and forge a cool blade with that ?
You mentioned Re was hard. Did I miss it, or did you not tell us it has a hardness of 7 on the mohs scale (etc)?
that red color was definitely iron that was trapped in the aluminum oxide grinding wheel
I suspect Rhenium is older than 99
The anniversary of their first meeting rather than a birthday.
I’d like a very big lab with plenty of ‘space’ to make stuff.😊
I love the professor
84/85 is a surprising age for a volcano explorer.
Thank you
You're welcome
Professor has a jet engine! 😮
Perc the vent gasses through a hydroxide solution or something to collect it.
Anyone started a campaign to get Neil an office with windows?
alright science time
0:17 skip to the best part
20:10 - "We all went to Neil's office, which has no windows [...]"
Is that not called a closet?
I laughed at loud at "rock star." Good one.
Pls update the microphone 🎤 there’s some high pitch noise at the back when someone talks
19:35 True love for Neil at last?
yeah. but did you let the cat play with it?
(a silly offering for the algo-deities of the tube'y'all)
Petition for a window in Neil’s office
are rocket engine too made of renium.
17:10 neil voice reveal :D
bro started the post script "so we're here-" YOU DID NOT oh okay okay
Neil is *my* Salt Bae
What was wrong with the sound on this any time he spoke there was a low grating noise, I'd rather hear the noise all the time rather than beeping the whole way through the narration
I don't know how you manage to make the microphone recording the professor sound as old as him, but it's very atmospheric.
In all seriousness, either get the mic closer to the professor so you don't have to crank it up so much in post, or buy a really good one. I would propose the former because all it would cost you is having a microphone in your shot - which nobody would ever bother about. But it would be nice to hear the professor in clarity without being bothered about slight halling or hissing background.
(Edit: sound becomes a lot better later, and gets worse at the end again. Not sure what the reason might be. Maybe its also my speakers not presenting his voice very well, sorry for the sass!)
Could a Geochemist have knowledge of the answer to the question at 11:42, concerning Volcanoes & Rhemium, where the Professor said "He was NOT A Geologist?"
As the rhenium oxides are so volatile, I imagine it is simply distillation from below and condensation in the cooler, higher parts of the vents, similar to the production of encrustations of pure sulphur. The hydrogen sulphide then fixes the rhenium in place by replacing the oxygen in the rhenium oxide to make rhenium sulphide.
@@pattheplanter -- I LOVE the way these Professors teach Chemistry and it's History.
ici ça marche !
Great videos, but I really miss Pete License and all the other cast of characters that were in these videos performing experiments before the pandemic. I guess they've all moved on...
Pete is now Head of the School of Chemistry!
@@periodicvideoskudos Pete!
Why does Neil´s office have no windows? 🧐
Rhenium is really weird in the form of perrhenic acid.
He hasn’t aged in 30 years
Liked and shared.
Thank you.
pink flame defiantly a potassium...lol
Why do I get Vespin gas vibes?
