Do not repeat the experiments shown in this video!
Today I would like to tell you about such a metal as ruthenium which has recently received heavy coverage in the mass media. In the periodic table of chemical elements it belongs to the so-called platinum group which unites metals, chemical and physical properties of which are similar, and also those metals that are commonly found together in their naturally occurring minerals. Ruthenium is extracted from platinum ores. There are lots of ruthenium rich deposits in the Ural Mountains and also in the mountains of South and North Americas. By the way pure ruthenium was first extracted from ural ore by a Russian scientist, Karl Ernst Claus in the Kazan Federal University. He named the element after his motherland - Russia. He gave the metal its Latin name to be precise. The pure extracted ruthenium is a shiny and heavy metal with a quite high melting point - 2334°C. As some of the split ruthenium balls indicate, the metal is quite fragile and almost can’t be forged. From a chemical point of view, however, the metal is very similar to its platinum fellow metals belonging to the platinum group. That is why it doesn’t react actively with most chemicals. This property of the metal can be used to grow beautiful metal crystals. The crystals form when ruthenium particles are transported as gas in vacuum and at high temperatures. Such crystals do not have oxide coating that is why they look stunning. High resolution macro photos of such crystals look particularly interesting especially when crystals glitter in contre-jour lighting. Ruthenium almost doesn’t oxidize in air at room temperatures. Some minor changes occur only at high temperatures. After heating up with a gas burner ruthenium crystals start covering in multi-color ruthenium dioxide layer. Its thickness is extremely small. Because of being very hard and very corrosion resistant in air, this metal is often used to coat the surface of electrical terminals in order to prevent them from getting oxidized and worn out thus ensuring reliable connection. Pure metallic ruthenium is also added to superalloys of nickel with aluminium which can withstand high pressure at high temperatures. These alloys are used to make blades for jet engine turbines. Being so chemically inactive ruthenium also doesn’t react with acids. It doesn’t dissolve in any acid, not even in boiling aqua regia. Anyways, this noble metal can easily oxidise in plain chlorine bleach solution containing sodium hypochlorite and traces of alkali. It can be clearly observed that upon heating up the metallic droplets slowly start to dissolve giving the solution brown color. This reaction produces sodium perrhenates and ruthenates which are quite necessary compounds nowadays. If sodium is substituted with bismuth in such compounds, you will get bismuth ruthenate - a chemical used with ruthenium dioxide to make thick film miniature resistors, which are used in lots of smartphones, and also hard miniature electronics. Later when the ruthenates in the solution react with hypochlorites they can form dark ruthenium tetroxide. - Věda a technologie
I am nor Russian neither English, but I do understand perfectly Your message! You talk clearly, without tricky music on background! Thank You!
@Mutong Tang you are a nazi pig
i had some trouble at first, but after a while you get used to his accent and understand pretty much everything
@Mutong Tang You should hate Académie de France they were not able to find this metal in Platinium Ore and that is why Karl Ernst Claus name of this metal is in use not the one that Jędrzej Śniadecki proposed 27 years before him.
Bruh as if
you are kidding, right?
One thing I love about your videos is how you have manually inputted subtitles. For a smaller channel with English obviously being a second language, it's awesome to see how much effort you put in so everyone can enjoy your content.
Smaller channel? He’s 3/4ths of the way to a million subs!
Now this is how educational should be. I was absolutely enthralled by your expertise and presentation. BRAVO
This guy gives more information per minute than anything I have ever seen. I love this.
I love how much work you put into these videos. It really pays off with the top quality you give.
I love your videos, man! Straight up the most informative and entertaining chemistry videos I've ever seen.
Love your vast knowledge ! On these metals , fascinating !
Ur channel is awesome n inspirational to young scientists don’t stop this is a great contribution to scientific future 👍
Another great video.
Very educational.
This is honestly the best channel on CZcams
Your educative videos are incredible. So much information so clear to understand in such a short time. Great work. You are an amazing teacher!
One of the main uses of ruthinuim in my field is as an electroplating on top of white or yellow gold alloys to make brown diamonds appear more appealing. Often it is miscalled black rhodium plating, but black rhodium is not as dark so some companies are trying to keep it as a trade secret.
Matthew Familia jewelry and watch repair
Matthew Familia it's not too easy to get into if your family isn't into it, I went to GIA, then car sales, then jewelry sales, the food service, then management in food service, the. I resold used jewelry and tried my hand at repairs, then got a job in jewelry repair, then I opened my own shop after I knew what I could do and knew other who can do what I can't. That's the short version.
That's just jewelry, that's not a real use, the people who waste their money on that might as well be birds impressed by shiny scraps of aluminum foil, a more interesting question is what catalytic behavior can it have.
medexamtoolsdotcom did someone shit in your toaster or something?
Matthew Familia I bet you hate bitcoin too
Love your videos and channel Thoisoi - keep them coming 👍🏻
His accent always seems to add a certain amount of legitimacy to his subject matter.
Totally!
@@theral056 joyful for those listening....
I find he speaks too quickly for easy understanding.
@@bloggsie45 appears to me you gentlemen are not applying your wisdom... youtube can be .75 % to slow down the wonderful presentation of most appreciated chemist #Thiosol2 and His practice English foreign language as he demonstrates also possible to caption into language of all whom may also be practicing their non native language English... otherwise it would appear comments reflect other than ernast appreciation of visual properties demonstrated...
MrBadBricks now why’s that he’s just a guy teaching ya about some metals
Wow… I think…
I know more about an element today!
And… 4:15 is so beautiful!😍
Over the years I believe I have watched all of your video on the different elements. Thank you for sharing your knowledge.
You present your videos brilliantly, I love it.
I don't quite understand what people find difficult with your English. Sounds just fine to me. Then again I dated a Russian immigrant for a couple of years. Only had trouble understanding her when she appeared to be angry at me.
That's all women lmao
😂 appeared to be mad at you? Good stuff!
Danielle Hilton 😂 😂
It's mostly easy to understand, but it's pretty clear that he's reading from a script and doesn't really understand what he's saying. You can tell at 0:40 when he says "By the way pure Rothinium. Was first extracted" - the unnecessary pause and strange intonation sets people's teeth on edge, much more than having a Russian accent or making a grammatical mistake. That's why people comment on it so much.
J R his he definately can speak english, but its probably a working knowledge. Still he knows mors english than i know whatever his native language is.
What a great video man. Caught me totally by surprise the level of this story and then the open source reach out. This is now and our future. Thank you.
Thank you for this very complete video once again ! :)
Great information!
I'm new to your channel and i have never even come close to a chemistry class but you make this easy to understand...i learn much from your videos..thank you for posting these.
Thank you for educating and entertaining us with these videos.
I love your videos, thanks for sharing. Subscribed.
Thanks for sharing some interesting information about an element that very few of us even knew existed.
Love the videos. Someone needs to somehow start incorporating your info and experiments with Periodic Videos. I want like an entire half hour episode to exist for every element. I was getting worried when you started talking about the radiation accident. Glad you made a disclaimer, we can't have you falling off any balconies... Too soon?
Keep up the good work.
I enjoyed very much your presentation. It was refreshing how you simply presented the facts and allow me to do with it as I will.
Very informative with wonderful visuals !!! Keep up the food work ;)
Good video, well researched, good video clips used...thanks for all the work
Thanks for the great video. I continue to share them with my daughter
Very interesting video. I learned something new and exciting. Please ignore the haters who mock your accent and keep making moar videos for us. Oh, and the cat is so adorable too!
Beautiful video! I love your work, fella. You accent is most pleasant here in the USA too! Could you make a video that shows how many elements of the periodic table are found in a single cell phone or other modern hi tech product. Keep up the awesome work!
videolabguy I would love to know the answer to your question. I hope he does make a video about it, but I think I'm going to do a little research and see if I can figure it out myself.
@@mikeoliver3254
How did your research go?
His Russian accent is the 'most pleasant in the US'? I bet our traitor of a president would agree. Also, how do you know he's in America?
@@WoodysAR Can't survive without bringing up politics eh?
@@WoodysAR
So now that he's out who will you blame for all your forthcoming ills? Oh, right, you'll just keep blaming him until your last breath.
Thoisoi you have done an outstanding work.
How did I end up here? It’s 4am. Can’t sleep. CZcams must know I’m a captive audience. Good to learn something new that I'll have forgotten about when I wake up. 😉
Yup... it's early o clock, the beers are dwindling and I'm lost in the warren. Top banana🤓👍
I'd be a genius if I could remember everything I learned.
Thank you love the channel love science love elements
This video looks great in 4k. Thank you!
Great video buddy! Make sure to change the title to “mysterious” so you get more views from the CZcams algorithm! Keep up the great work!
Normal levels or gamma and X in Braşov, România. By the graph you shown the cloud passed twice my area with higher concentrations on 1st pass. Any Ru contamination should give some gamma secondaries (which I can measure)
I did not measure anything over the background radiation even after recent north-west driven cold weather wave and precipitations.
Also... It's true that I live in an area pretty well shielded by surrounding mountains so any low-passing contaminated clouds are spent well east from me. But high-passing weather is not captured, like in this case.
Again, nothing above 0.1mR/h.
Were safe for now. :)
Brasov....i've been there!
I love this kind of stuff. I love learning new things outside of my sphere.
You are a sphere.
@@clownslapper5270 Yes, I identify as a planet,
Great video Borat, keep up the good videos
THOISOI IS MY FAVORITE YT CHANNEL!!! Please make more element videos!
Most informative and educational presentation as outstanding work much appreciated.
Thank you for yet another great video!
Thanks for the daily dose of science my guy.
Fantastic video!
Amazing! Great video. Thank you.
Thank you for another excellent video.
During my college days,I used to study elements and compounds in periodic table ,but I didn't know the application process, occuring place,I had many doubts which solved through this vedieos with remarkable experiments,it helped me a lot, Thank you sir👍🙏
Thanks for the news!!
Хорошая работа! Спасибо!
Good Work! Thank you! Thumbs up!
Thanks for video. Fascinating.
I simply love how you say "such a metal as"... while the grammatically correct way to say it would be simply "I would like to tell you about the metal XY"
But it is actually a signature sentence for your channel.
Btw. keep going! Between Nile Red, Nurdrage and You, nothing shall remain hidden about chemistry before us.
yes, don't change it!
"Subscribe to my channel to see many more new and interestink..."
I think that incomplete sentence is the signature.
add these to your list :
Chemplayer
Extractions and Ire
Doug's Lab
Applied Science
Don't forget NIleRed
I actually really don't like chemplayer. The computer audio pisses me off.
Doug's lab... yeah... he is disappeared again :/ About the rest, I checked them out, but not really my piece of cake.
Man, they should put you in one of the Hollywood movies! “The world is mine!!!” Mr. Bond, mine!!!!!! 👨🏼🔬
Excellent video!
That was a pretty awesome looking metal when dropped into a solution.
Great education and awesome research put into all your videos. Thanku again
Beautiful photography!
Thank you VERY MUCH for not bringing in politics to this amazing channel.
plus closed caption is also good so if your having a hard time hearing him cc can help with that! good video!!
This was fascinating!
very interesting details, thank you
Interesting channel, thanks!
Nice job bro!
Ruthenium is now being used to coat silver coins to make them dark to be used as a design.
And they're Beautiful IMO
I bought a series of Canadian silver coins, called Nocturnal By Nature. These were coated with Rhodium, not Ruthenium.
@@Ottee2 they are indeed very beautiful
I use it together in a Supplement daily
Wow wow wow love it love your channel keep going
Good work. Well done.
Great Channel.
Have SUBSCRIBED 😀
Good work!
Thank you Thoisoi :)
very good video, no crap music, just educational
Your videos are fascinating
Where have you been? I have been waiting for more videos.
Always great videos.
The Metal's Amazing And Your Great And It's Works Are Amazing And I Think Will Do Something In Future....
Your channel is very interesting.
Great work as usual. It was wonderful to see you working in the glass foundry. People always look much different than I imagine from their voices.
As far as the waste cloud...nothing ever happens in Russia, right?
😎
Is that first image corn flakesium.
Thank You very informative!!!
These guys is great!
Great lesson and demonstrations. Interested Ru dissolves in alkaline oxidants. You could also try it with ammonium chloride plus ammonium hydroxide plus hydrogen peroxide. Copper goes up with this mix like a rocket!
I love how expense was a higher factor in not being used commercially as much as its toxicity, I say this while sitting next to a mercury coil thermostat so I can't say much.
This could be turned into a cool ultraviolet Lamp if used with custom glass structures, you can decorate the outside of it with the shiny stable metal too.
Nice video!!
You are doing a wonderful job and a giant stunning
This is very fine. Oliver Sacks, a hero of mine, who wrote a deeply personal book about the table of elements called Uncle Tungsten, would have loved this series.
Outstanding photomicrography.
Cool video like always. Can you make another video about mercury ?
Great visual effect when you put ruthenium in water at 4:15 and 6:30. :-) Very interesting subject.
Thoisoi2 - Have you made a Video on Mercury??? That was my favorite Toy as a kid...
I love your namings.
Very interesting video 👍
Ah Ruthenium the metal that enabled us to develop warp drive in 2187.
That was very interesting.
Ruthenium with a bit of platinum (or tungsten) is also usually used for the tip of fountain pens nowadays. Iridium has not been used for decades.
I love these videos!!!!! 🤘🤘🤘🤘
Good blogg thank you for the info 'please do not stop teaching.. ALLof our children need knowledge.
Another excellent video, very strange about the closed business 🤔
This dudes accent makes me think of being tied to a dentist chair with a tray of fucking terrifying surgical instruments next to it while he's calmly asking me who i work for.
Good Information😊
Great Channel..
