Hello everyone, Today I would like to tell you about the metal 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, chemicals and physical properties 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 the South and North Americas. By the way, pure ruthenium was first extracted from Ural Ore by Russian scientist Karl Ernst Claus in the Kazan Federal University. He named the element after his motherland, Russia. The pure extracted ruthenium is a shiny and heavy metal with a quite-high melting point: 2334C. As some of the split ruthenium balls indicate, this metal is quite fragile and almost can’t be forged. From a chemical point of view, however, this 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 of ruthenium. The crystals form when ruthenium particles are transported as a gas in vacuum at high temperatures. Such crystals don’t have an oxide coating, that is why they look stunning. High resolution macro photos of such crystals look particularly interesting, especially when the crystals glitter in (inaudible) 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 crystal gets covered in a multicolored ruthenium dioxide layer, which has little thickness. Because of its hardness and corrosion-resistance to 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 a 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 oxidize in bleach solution containing sodium hypochlorite and traces of alkali. It can be clearly observed that, upon heating up, the metallic droplet slowly starts to dissolve, giving the solution a brown color. This reaction produces sodium ruthenate and perruthenates which are quite-necessary compounds nowadays. If sodium is substituted with bismuth in such compounds you’ll get bismusth ruthenate, a chemical used with ruthenium dioxide to make thick film miniature resistors, which are used in a lot of smart phones and also hard miniature electronics. Later, when the ruthenates in the solution react with hypochlorite, they can form dark ruthenium tetroxide (Correction: ruthenium dioxide, tetroxide is colorless). The tetroxide of ruthenium is often used in organic synthesis, because it can oxidize any hydrocarbon. I think you have noticed that ruthenium has more applications in the form of compounds. rather than in the form of pure metal. Since recently, metal organic compounds of this metal have gained a great deal of popularity. For instance, oxidation state of ruthenium in Tris(bipyridine)ruthenium(II) chloride is +2. This so-called coordination complex is being extensively studied by scientists because of its photochemical properties. First of all, this substance glows well in ultraviolet light. Besides that, it can also catalyse chemical reactions when exposed to ultraviolet light. For instance, when water is oxidized to oxygen with oxidizing agents, or when water is reduced to hydrogen with the presence of this ruthenium complex. Apart from that, this ruthenium compound can also be used to make more efficient thin film solar cells and also flexible LED displays. Such ideas, however, have not found widespread use. I think it’s because of the high cost of this metal, and perhaps because it might be toxic to humans. It does not (inaudable), as there exist a few articles that speak about how ruthenium metal organic compounds can cure cancerous tumors. Until now, I have been telling you about the ordinary, non-radioactive ruthenium that consists of 7 stable isotopes that occur in nature However, there exist 27 more radioactive isotopes of this metal. One of the most widely known amongst them is ruthenium-106 which forms as a result of the radioactive decay of uranium in nuclear reactors. This isotope can be separated out from others, and be used to treat eye cancerous tumors with lower relapse rates. Russian Rosatom also produces this isotope In the end of 2017 there was made a lot of noise in the mass media about supposed Ruthenium-106 contamination cloud above Europe. At first, Mayak nuclear plant in the Ural mountains was under a cloud of suspicion but Russian authorities denied their involvement and officially claimed that the contamination was caused by a satellite that burned up in the atmosphere. Unfortunately, I haven’t found any information of satellites that use Ruthenium isotopes as radioisotope energy sources. If you know something about it, please leave a link down in the comments below. Nevertheless, the disputes about Ruthenium-106 cloud above Europe are still ongoing. I am not making any claims, and not taking politics here. I’m just sharing information from the open sources. It is up to you to make conclusions. Nevertheless, in spite of having a reputation of unstable isotopes, nonradioactive Ruthenium is used in a wide variety of applications. Perhaps in the future this metal’s compounds will be used in the new solar cells or in efficient light-emitting diodes. Anyways, as they say: “Wait and see.” For the provided Ruthenium for the experiments I’ll thank the company I’ll put a link to their site in the video description Now you know a little bit more about one of the other metals.

  1. I never heard anything about the Ru 106 cloud over Europe! Not widely publicised in UK! Could only come from a manufacturing accident, to release that much! Obviously a very secret, and unsafe, establishment that will be kept from public perception. great, interesting vid btw, well done.

  2. Next time youโ€˜ll speak on a video, please learn first how to pronounce good English first.
    The topic is very interesting but your accent caused me not to watch it to the end

  3. Silver – Ruthenium alloy recently found to have anti-bacterial properties:

  4. Hi .I have some things you want to see it 30 grams. Of osmium . For seel. plz contact me in whatssap. 00212614949041

  5. re: 106 cloud europe… how to interact in atmosphere to concentration levels reported as 106 cloud europe… ? also point origin of first reading…? thank you as always for all you are excelleny providing regarding Noble's

  6. His video's are always right down the middle.
    If you know nothing, you learn a little bit; if you go to the wiki page you'll always learn more.

  7. The Ruthenium cloud was from their testing of unshielded nuclear-powered cruise missiles

  8. Goddamnit putlin, ffs even after chernobyl still lying. I made conclusions, my russian brother, time to banish that pussy ass bitch from the leader post

  9. Ruthenium 106 Has Cuanto magnetism. I would be very interested to hear what information you have gathered on this recently discovered information about Ru (106)

  10. Massive radioactive cloud over europe you say? Russia, what did you do this time?!?!?
    Russia: Blyat, it was not Russia

  11. Titanium and ruthenium alloys will make the best electric guitar strings (as a coating, most likely.)

    No one has yet to approach this market yet… ๐Ÿ˜‰

  12. I found out this existed cause I typed a typo and this word came up and it sounded cool so I looked it up ๐Ÿคฃ
