One of the strongest lightweight materials known 

Great ! thanks for your translation :)

Doug Johnson you just bullied MIT to change their title on a video and it worked

"bullied"

They found a way to arrange flakes of Graphene into a 3D structure without losing its properties. For now Graphene is only practical in a 2D application. Stacking them in layers would make it just as dense as any other carbon block, which would make it no different than any other lump of diamond. So arranging bits of Graphene this way would make the structure porous and lightweight, without sacrificing the material strength. But the structure can also be made using other conventional materials.

big bruh moment.

Dis comment, tho.

well then check hydraulicpresschannel

Glad I'm not the only one confused by the structure of this video

sphinxrave I think that they are talking about applying the shape of graphene to non-graphene materials in order to obtain higher strength, because graphene is strong because of the geometric arrangement of its atoms? This point is stated at 1:23. However, I'm pretty confused too. Gyroids aren't new, if Wikipedia is to be trusted. Apparently, it has been used experimentally for some time now due to its unique geometric properties. It appears that these MIT guys are saying that the shape is also mechanically very strong, besides its other characteristics, which are already known.

The only thing that would make sense to me (but it's not at all what they _said_ in this video) is that they made graphite in gyroid-shape, rather than sheets, to make it a super strong but 3 dimensional structure.

The language used was just plain confusing. They successfully designed New 3-D Material (presumably using graphene). Analyzing atomic interactions produced mathematical framework for simulating an experiment. Here graphics show a simulated crumpling "experiment simulation" and "actual experiment setup", except the graphene is irrelevant now somehow, since actual experiment setup is now using plastic.... To test their material (which, is graphene? no? ), they printed 3d models (using plastic) ... ??? It seems the team started off from graphene and concluded that geometry > graphene. And from the article: The team used 3-D-printed models of the structure, enlarged to thousands of times their natural size, for testing purposes. I welcome anyone to change my mind, but I feel like comparing atomic simulations on graphene flakes in a gyroid vs experimentation on macro objects several thousands times bigger (more like millions) is not highly applicable, and like +Tiles Murphy said, it can be a mechanical property, but then I think the graphene part of this article/video becomes academic click-bait.

I think you might be expecting too much about the graphene connection in this video. I agree it is confusing, but I rewatched the first 30 seconds a few times and the transition point is at about 0:19. The way I read that section is this "Graphene, in 2D, is one of the strongest materials known, but it's hard trying to replicate that strength in 3D. Here's a new 3D material that's 10x stronger than steel" Basically they're focusing on merely building strong materials, they're not concerned with graphene except for its strength.

There are so many things you got wrong and im not explaining everything, unless you were joking.

@Raita Xross if you don’t want to explain why did you bother responding

strength of a material isn’t dictated by how much is used but by the geometry. Take trusses for example

True

Also nice for being the only comment here not from 5 years ago. Hello fellow person from this time 👋 And happy New Year later today depending on where you are! ❇🥂 (couldn't find the party hat and firework emojis 😔) I guess as they say in these comments sometimes. greetings from Florida

Please get this comment viral till they add this as an option.

@@mohammadabboud it already was an option at the time you made this comment

Lucian Leesonja They also said "...graphene is thought to be the strongest of all known materials." I guess they haven't given a name to the experimental 3D material they made.

and that's news to who?

Lucian Leesonja: It's just a scale model, just like Derik Zoolander's "School for Kids Who Can't Read Good and Want to Do Other Stuff Good Too" isn't actually a school for ants.

It's a plastic model built for evaluating the gyroid structure, to see if that is what graphene can be feasibly molded into.

materials and 3D structures are not interchangeable

le graphène est très élastique alors la forme change beaucoup, mais j'imagine qu'ils ont utilisé un plastique qui a les mêmes propriétés, à une fraction de la force.

mais avec une porosité d'environ 85% les morceaux cassés ne changent pas grand chose.

I think that you mean the "shape" changes by collapsing, molecular geometry is not affected.

I'm not familiar with chemistry, but I think you might be right. I thought it was implied by the video that it was the physical shape of the material that made it stronger.

The video is so confusing and misleading that I already labeled it as "waste of energy" and won't even attempt to clarify it to myself:) But just to finish what I started: Yes, you are right, they also imply that the physical shape has effects on the stability of object. I merely commented to point out that there is also sth called molecular geometry and it is different than the aforementioned shape. Cheers..

Then what was it?

comentator not much. In this video they haven't test the new material. This pink part was a macro scale model of meta material they are working on. Those parts were made with ordinary plastic. They meant to represent how different meta properties can influence the behaviour of the material under stress. In the video they said that materials can be made using this principle however they have not shown any materials or parts made using this principle.

That makes little sense, but how does the meta property of thickness even translate over to graphene?

sphinxrave that was the point of this video

Rafal Lasocki it is? But how would thickness meta property apply to a 2D graphene structure. Or how a atomic simulation of graphene can be used to approximate graphene flakes which won't be perfectly continuous or uniform? I'm open to learning more about the research, but this delivery needs more work.

sphinxrave you are asking all the right questions. Imagine how material with such properties would change the World. 20 times lighter than steel and 1000 times stronger This research is potentially worth billions and it is unlikely they would give away any crucial details. For now we must also assume this is only an idea and only tested by computer simulations. (Edit: grammar)

True!

marter1234 gaming yes....

SteepVisions you saw that comment too huh?

Known what? One of the very first patents pertaining to the production of graphene was filed in October 2002 and granted in 2006 (US Pat. 7071258).[38] Titled, "Nano-scaled Graphene Plates," this patent detailed one of the very first large scale graphene production processes. Two years later, in 2004 Andre Geim and Kostya Novoselov at The University of Manchester extracted single-atom-thick crystallites from bulk graphite.[7] They pulled graphene layers from graphite and transferred them onto thin SiO 2 on a silicon wafer in a process called either micromechanical cleavage or the Scotch tape technique.[39] The SiO 2 electrically isolated the graphene and weakly interacted with it, providing nearly charge-neutral graphene layers. The silicon beneath the SiO 2 could be used as a "back gate" electrode to vary the charge density in the graphene over a wide range. They may not have been the first to use this technique- US 6667100, filed in 2002, describes how to process commercially available flexible expanded graphite to achieve a graphite thickness of 0.00001" (one hundred-thousandth) of an inch. The key to success was high-throughput visual recognition of graphene on a properly chosen substrate, which provides a small but noticeable optical contrast. The cleavage technique led directly to the first observation of the anomalous quantum Hall effect in graphene,[28][30] which provided direct evidence of graphene's theoretically predicted Berry's phase of massless Dirac fermions. The effect was reported by Geim's group and by Philip Kim and Yuanbo Zhang, whose papers[28][30] appeared in the same issue of Nature in 2005. Before these experiments other researchers looked for the quantum Hall effect[40] and Dirac fermions[41] in bulk graphite. Even though graphene on nickel and on silicon carbide have both existed in the laboratory for decades, graphene mechanically exfoliated on SiO 2 provided the first proof of the Dirac fermion nature of electrons.[citation needed]

because why not

This has been in use for decades. Just look at your car..
