Starlite Just kidding, I mean if you think you can make an interesting video from it, go for it. But that stuff is a bit like a mythological material more than a real engineering thing.
@@wowwchen5390 Hey Krystene! We have a video on graphene here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IesIsKMjB4Y.html Thanks for watching! - Cory
Years ago Nitenol was classified. It had great memory but they didn't know what to do with it. Years later they realized they could pit it in heart defects if the place was going to have to move a lot, I have one in my heart. They squeeze it in and slide it in the heart. When I first got it I recall listening in my heart there. I heard my heart going. Ching ca Ching Ca Ching. On and on. Finally the heart will grow over it and it can't be heard anymore. The thing fixed the hole in my heart. I'm 69" .
Same, in the 90s I saw a thing on TV about how they were using it in surgery. A ring would be heated to expand and would then clamp bones or something once it cooled.
I didn't see it mentioned, but the name "Nitinol" is from "Nickel + Titanium + Naval Ordinance Lab" (I used to work for a company that used it to make cardiac stents)
@VergeScience It was a great honor working with you to produce this video and educate the public about nitinol. Nitinol truly is poised to initiate the next technology revolution and we're thrilled to join you in a part of it.
Respected Sir, I am a 10th grader from India I have some doubts as well as ideas about Nitinol mostly based on how it reacts with Electric Current How may i be able to contact you?
@@scientificshrey2089 Hi Shrey, many Nitinol parts are actuated by electricity. Feel free to visit our site kelloggsresearchlabs.com for more information.
The first time I came across nitinol was actually in an escape room where we found a wire and learned that we needed to heat it up. When we applied the heat, the wire shifted itself into words which led us to our next clue. It was extremely clever! I'm glad that people smarter than me have found applications outside of entertainment!
@@cushionofair I’m trying to remember. I think earlier in the room we got a hairdryer and we just tried it on everything we found. It’s been a few years though so the details are fuzzy.
@@beni2cc Yes, a HDD made of graphene(carbon sheet) with gold, platinum, palladium and rhenium atoms for example, each encoding two bits(00,01,10,11). Many petabytes per square inch. Would be slow to read though, and almost impossible to write to.
This reminds me of what has been described as recovered ufo material from the Roswell crash where there was a metal foil type material that you could crumple and fold up and it would return to its normal state.
I have gone from a video titled " how toddlers flex on other toddlers" from gus johnson to this. RU-vid recommendations are absolutely impeccable at 1: 30 in the morning
I would say this is what composes the Lamborghini Sian's rear engine flaps. Which automatically open up when engine warms up to a certain temperature without the help of any electricals! Although they haven't shared any details on its working.
It’s about time someone did something with this stuff. Heard of it since I was 7 years old and had trouble even looking it up till about 10 years ago and finally people are doing something.
I worked with Dr. Santo Padula in the fall of 2015 as an intern at NASA Glenn in CLE; absolutely brilliant guy. I was so fortunate to have seen his research and the Nitinol rover wheel design.
This is a great explanation of the properties and applications of NiTi alloys! I’m an orthodontist and we use the shape memory properties of NiTi wires in EVERY SINGLE patient! The result is greater comfort and duration of activation (fewer appointments = fewer missed school or work hours). Thank you, science!
This is honestly pretty incredible and my mind is racing right now thinking of possible applications to replace current everyday products. This metal could perform movements that would otherwise need mechanical processes. A crane or lift would be an example. The advantage here is the metal does all the work; only a heating and cooling device would be needed instead of a motor.
One big application that Othmane discussed is replacing hydraulics on heavy machinery. SMAs also react when running a current through them (any form of heat, really). - Cory
@@VergeScience Wow, I haven't even thought about that. In my mind, I was picturing an auxiliary heating system but I knew that would be pretty inefficient. An electrical current would allow for a more compact system that could be used in an insulated enclosure to not be disturbed from exterior temperature changes from say space or even underwater. Very Cool!
@@EchiBawn Yup! Othmane is working on a shape memory alloy rock splitter that can be placed inside a drilled hole and “charged” to expand with great force. It will allow for demolition on Martian missions where it’s impossible to use chemicals or explosives.
How would you use it in a crane? I’m assuming you mean bend the crane down and then heat it up to lift the load, but that’d be such a thick rod it’d require a lot of work to bend. Unfortunately there’s no such thing as free work, your just preloading the work in the material
You mentioned the drawbacks: it’s expensive, and difficult to work with. That’s why it’s (basically) only used in expensive applications, like medical devices.
My uncle had shown me spectacles made out of memory metal 22 years ago when he used his hands to completely crumple up the temples and bridge and then released them, so that they unfolded back into their original forms.
Hey DeltaXY! A majority of our research came from the manual "Shape Memory Alloys: Modeling and Engineering Applications", published back in 2008. However, our primary sources in guiding us through the basics of Nitinol and SMAs in general were Othmane and Santo. We used a variety of other studies and sources to fact check before publishing, but typically don't list fact-checking sources/studies unless we reference them directly. Thanks for watching! - Cory
@@VergeScience Thank you very much. Again this diminishes in no way the superb quality of your presentation. I'm always glad that I subscribed when I watch such great content😊
I am a magician, I saw a special spoon 1 time made of this. It was super expensive and didn't look much like a real spoon. So you are only partially correct. Most of us thst do that do NOT use a spoon made from this stuff. In fact bring me a spoon from your drawer and I can bend it useing the power of thought only!
@@scientificshrey2089 sorry man, I have not studied Nitinol at a research level, it was just one of the topics in my UG curriculum. You can find help from professors at IIT-M, the research team there is one of the best in Metallurgy in India.
@@carmensmithaguirre3049 it's the study of materials like polymers, composites, nanomaterials etc, useful for technological applications, and the related science. Metals, technically materials, are generally studied under Metallurgy.
What is more exciting, is the fact that once Quantum Computers can crunch extremely complex problems, maybe it can tell us what metals and alloys to mix to create super substances and methods that we have not thought of for creating these new designs. The future is gonna be insane.
As a blacksmith, this was my first thought! This alloy is really unlike any other kind. I actually work with nitinol in my day job, and would love to forge with it.
I know some paragliders use Nitinol wires at the front where the cells are. This way the paraglider is a little less prone to collapses in rough air. If this is the future, I think Titanium and Nickel are a good investment opportunities 🤔
A science teacher once showed my class a small amount of this metal, she talked of how it was gonna be the next big thing and they would make self repairing car body parts from it but then i never heard of it again until now That was about 20 years ago
I think this is the same material used in Lamborghini Sián FKP37 for its auto opening engine bay door, that work on its own without any computer help. They say it open when the engine bay temp reaches a threshold.
You can make an efficient motor using the nitinol memory wire to run off the weather tempture. One of the things reverse engineered that wasnt to complex in the ufo crashes 1949 1950
Hey there, it's called the Scorch Torch Orion -- it's a butane lighter, so it burns way hotter than needed for the purposes of this video, but does the trick. I wanted something with a bluer flame and found this at the store down the street. Thanks for watching! - Cory
They reverently released a freedom of information act because an author asked specifically about this metal and not the crash, and they admitted to retrieving it. They released this of January this year
At least someone else is saying the same thing in the comments. Sadly most of these idiots think that this new tech. However, this adds flames to the fire of if we are alone.
I have a wrench that has similar properties. It's supposedly from the Navy. Its hard but turns floppy after applying over 200lbs of force. Snaps back violently.
Reminds me of the metal found in the Roswell UFO crash. supposedly. The crash happened in July 7, 1947, two years before it was used by Dr. William j. Buehler in his rockets.
Question - isn't titanium very difficult and expensive to procure? The ratios of the metals generally hover around half and half, so using nitinol on the scale of something like replacing the whole tire industry seems like it would demand an unsustainable degree of resource extraction.
I'm a time traveler, coming from a month ago. I wanted to let you guys in the future know that the Perseverance rover doesn't use those wheels and they went with normal wheels. Sorry.
Great video!! NiTi was a huge game changer in orthodontics. Shape memory and consistent light forces means fewer wire changes and light forces over stainless steel. Even cooler, the transition temperature of the wires can be designed so they are super flexible at room temperature and “remember” their shape at mouth temperature.
Nitenol is essentially the reverse entropy via thermodynamics changing the state of an action or object especially real life time travel ,just like the movie tenet
Literally worked with this in our first materials science lab in like 3rd week of my 1st year at uni. It really was mindblowing seeing this for the first time
Was watching a thing on the UPARS channel about Roswell, and the supposed crash in 1947. They found sheets of material with similar properties, I'm not saying it's the same stuff; that stuff was hard to damage, but you can't help think of it when you watch this.
