Vanadium, a transition metal prized for tough steel alloys, is present in the human body in minute amounts; its compounds are considered toxic. The few species known to accumulate vanadium include varieties of marine algae, red-capped fly agaric (amanita muscaria) mushrooms, and sea squirts. Our closest invertebrate relatives, sea squirts are masters of molecular recognition and chemical concentration.
Vanadium is a transition metal of many colors and was discovered by Andrés Manuel del Río in 1801, who named it panchromium for its colored salts, then erythronium (fr. Greek erythros), as the salts turned red with heat. Del Río later dropped his claim, persuaded he had found impure chromium instead. In 1831, Nils Gabriel Serfström independently identified the element, and del Río’s claim was restored. Serfström’s name remained, inspired by Vanadis (Freyja), the Norse goddess of beauty, love, and war.
Vanadium’s compounds appear lavender, green, blue, or yellow, depending on its oxidation state. It forms a golden pigment for ceramic glazes, tints glass green or blue, and helps give emeralds their distinctive hue. Beneath the waves, filter-feeding sea squirts concentrate vanadium in green blood cells. The metal itself is silvery and strong: vanadium steel alloys are prized for heat- and shock-resistant tools, engine parts, armor plating, and structural steel. - Věda a technologie
Terrific presentation, but needs more pix of fabulous vanadinite specimens from Morocco!
Ron, in the middle of the 20th century an investigation was made to find out the reason why two Scandinavian towns had such different numbers of tooth cavities in children. Everything was the same it seemed. It wasn't fluorine in the water. It turned out to be vanadium. Like strontium, vanadium is needed for bone and tooth hardness. Along with chromium, it also helps insulin to be made in our pancreases and work in our cells. So vanadium is good for diabetics.
the knowledge of this material came to me I promise you I'm not lying, during a psilocybin therapeutic session. I am already passionate about working with the planet instead of against it and the technologies that can help save save the planet from which we all came and give it the respect it deserves. I would love to contribute to any company or somewhere I can make a difference I will work for room and board
Amazing video. I am grateful for this information :D
Surprisingly rare in mineral supplements.
great stuff
Ron, you said the vanadium flow battery could store a megawatt of electrical energy. ELECTRICAL energy is not measured in any kind of watts but rather watts times time.
Electrical conductive AND thermal insulating
@22:24 Megawatts are units of power not energy.
Hello Sir, how cane I tell if I have diamond
Is carnelian yellowcake?
Vanadium colors Brazilian emeralds.Columbian emeralds are colored by chromium. This is a big deal to geologists and to price.
Carnotite, not carnelian.
18 th or 19th
Vanadium's name sounds like it should be Dutch.
The nimble suit mainly press because comparison equally grip for a cut tendency. condemned, harmonious enemy
that Vanadium must be hella toxic though ... for Roscoe to look like this and die at merely 32 ;) -> 9:51
jk, it should be 1833 not 1883
