Now this is a technology post!

[–] [email protected] 19 points 2 months ago (5 children)

I don't know if I'd call materials science technology, exactly, but it's certainly more on topic than "business but at a tech company" posts.

[–] [email protected] 43 points 2 months ago (1 children)

Yeah yeah we get it, everyone is wrong but you and all that.

[–] [email protected] 20 points 2 months ago

That's ludicrous, because that's true for me and not them.

[–] [email protected] 37 points 2 months ago (1 children)

Cutting edge materials science and manufacturing is 100% technology.

[–] [email protected] 11 points 2 months ago

I only acknowledge technological advancements made in writing utensils. Keyboards and Typewriters do NOT count. So don't even get me started

[–] [email protected] 34 points 2 months ago

Of course material science is technology lol

[–] [email protected] 17 points 2 months ago

Wow what a stupid comment. Materials science is technology.

So this is what John Wick had in his suit

[–] [email protected] 15 points 2 months ago (4 children)

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

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.

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.

[–] [email protected] 8 points 2 months ago (1 children)

Layer it with Kevlar and good?

[–] [email protected] 6 points 2 months ago

It really depends on whether it can be made to meet all the other criteria required for armor. I think that it's too early to make any good predictions.

[–] [email protected] 6 points 2 months ago* (last edited 2 months 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.

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

Could this be used to make a space elevator?

What about a space escalator?

[–] [email protected] 18 points 2 months ago

Escalator is smart, because if it breaks, you can still walk to space.

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

[–] [email protected] 12 points 2 months ago (4 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.

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

[–] [email protected] 6 points 2 months ago (1 children)

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

it's very lightweight though, so it could reduce plastic usage by mass, by reinforcing plastic/other materials.

There's also no reason why polymers need to be made out of oil: See PLA, cellophane, viscose, etc.

[–] [email protected] 6 points 2 months ago (1 children)

Whether or not it’s plastic isn’t as big an issue as whether or not it’s biodegradable within a realistic timeframe.

molecular chainmail

[–] [email protected] 17 points 2 months ago (1 children)

Goes on to form company called General Products, builds spacecraft hulls. 😉

[–] [email protected] 8 points 2 months ago

Please, could we move to Known Space?

[–] [email protected] 15 points 2 months ago (1 children)

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.

Anyone know the cost per kilogram?

Edit: Apparently $20,000/kg

China, please respect this secret. Its made up with grapheme threads. Its impossible to understand exactly so we made a little picture with the molecules and such so you can't copy it.

hello I would like to order a thousand full plate mails

[–] [email protected] 7 points 2 months ago (1 children)

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