I'm sure this is real, but I see a headline like that and I think of schoolyard talk. Like, nuh uh, my armour has 100 trillion bonds, you can't shoot me.

[–] inconel@lemmy.ca 3 points 7 hours ago

I skimmed the article, scrolled down but people hasn't mentioned its mechanically Chain mail in atomic scale yet? Did I read it wrong?

[–] Naz@sh.itjust.works 6 points 10 hours ago* (last edited 10 hours ago)

Anyone know the cost per kilogram?

Edit: Apparently $20,000/kg

[–] FauxPseudo@lemmy.world 21 points 15 hours ago (3 children)

I can't wait to find out how toxic this is.

[–] Zron@lemmy.world 10 points 13 hours ago (2 children)

Good news, it’s completely non toxic.

Bad news, it costs 2 million dollars per square foot.

The pentagon will now take your whole paycheck.

Thank you for your support, patriot.

[–] HEXN3T@lemmy.blahaj.zone 4 points 12 hours ago (1 children)

Good news, it costs 2 million dollars per square foot, so they won't militarise the police further with it.

[–] IphtashuFitz@lemmy.world 6 points 11 hours ago

Well not immediately… Years from now when the military develops something even better then this will all become surplus and sold off to SWAT teams etc. for next to nothing.

[–] Batman@lemmy.world 1 points 12 hours ago

The article says the process is scalable.

[–] brlemworld@lemmy.world 5 points 11 hours ago

They will make it into a mandatory dress uniform for school children.

[–] phoenixz@lemmy.ca 4 points 12 hours ago

With these bonds so dense, I want to imagine that it would actually be quite non-toxic as these is little to react with.

Then again, I'm not a bio chemist

[–] Snapz@lemmy.world 27 points 18 hours ago (3 children)

....and uses it to oppress and/or disenfranchise poor people

[–] BeMoreCareful@lemmy.world 10 points 16 hours ago

You mispronounced promote American interests.

Me when the only thing I eat all day is weed and cheese.

[–] Dadifer@lemmy.world 5 points 12 hours ago

I did your mom stronger

[–] AeonFelis@lemmy.world 2 points 11 hours ago (2 children)

Why don't they just use diamond, the hardest metal?

[–] Haquer@lemmy.today 7 points 9 hours ago (1 children)

I thought Dragonforce was the hardest metal known to man?

Hardness isn't the best thing to have in armor. In fact, extreme hardness means extreme brittleness.

Tensile strength is more desirable in armor. That's the sort of strength that a string or rope, or Kevlar will have.

Those can stretch a bit before breaking.

Kevlar will stretch a bit when catching a bullet, this does a few things, but importantly it slows the bullet before stopping it.

So this new material will likely show extreme tensile strength rather than hardness.

[–] CoffeeJunkie@lemmy.cafe 2 points 8 hours ago

Correct. 🙂 Reminds me of when I wanted new tires & I was complaining about how some tires were rated for a criminally short life. I wondered which ones lasted the longest.

The mechanic then remarked that sure, they can make tires that last a hell of a long time & never puncture. But the ride would be so terrible because the tires would be tough, stiff, would work your suspension harder, and it would cost a fortune to boot. It's not worth it. There are multiple material, usage considerations when making a product. Really makes you appreciate the experts in their various fields.

[–] HelixDab2@lemm.ee 50 points 23 hours ago (4 children)

I don't know if this will actually pan out the way that they imply in the title; armor needs to have a lot of different characteristics in order to be practical. As in, resistance to heat and cold, resistance to acids, alkalines, petroleum distillates, salts, UV, and oxygen, and also resist deformation. Multiple materials have displays significant promise for armor, but had a very short lifespan in real-word conditions. For instance, there was a material trademarked as Zylon that was supposed to be better than Kevlar, and it was used extensively by Second Chance (a body armor company); several cops were killed when their armor failed, and the armor failed because of exposure to sweat and ambient heat.

Yeah, this is a super cool development, but remember that everything that comes out at this stage is hype.

[–] echodot@feddit.uk 15 points 17 hours ago (1 children)

The armor works perfectly fine as long as it's not exposed to oxygen. But when's that ever going to happen?

[–] MDCCCLV@lemmy.ca 2 points 12 hours ago

That by itself isn't terrible, that could still be used if it is sealed in something like an era brick if it's good enough.

[–] Soleos@lemmy.world 5 points 17 hours ago* (last edited 17 hours ago)

Yes... that's why they use the word "could". This is how research works and what reasonable science reporting looks like. There were no promises or wild claims made in the article.

This is still basic research, it's not close to commercialization.

[–] ryannathans@aussie.zone 58 points 1 day ago (1 children)

So this is what John Wick had in his suit

[–] NotMyOldRedditName@lemmy.world 15 points 16 hours ago (2 children)

I loved those movies but they went way to hard into that suit in the later movies. I got ridiculous lol.

[–] nul9o9@lemmy.world 9 points 14 hours ago

My favorite part was when he held the jacket up like a curtain. The material may be bullet proof, but the bullet will still push it out of the way like that lol.

[–] BeMoreCareful@lemmy.world 5 points 16 hours ago (1 children)

They did Rambo the franchise a bit.

[–] OhVenus_Baby@lemmy.ml 1 points 8 hours ago (1 children)

Same with the Fast&Furious it used to be about import vs muscle and real street racing. Then it became jumping hyper cars from falling buildings to the next building over and turned to shit. Like most over milked series.

[–] NotMyOldRedditName@lemmy.world 1 points 8 hours ago

Waiiiit, was it actually meant to be about import vs muscle, like that was it's intention? Or did they just happen to do that.

At least it’s not 100 trillion James Bonds.

[–] cupcakezealot@lemmy.blahaj.zone 1 points 9 hours ago

Not if Hank Scorpio has anything to say about it.
