zcd, to upliftingnews in Scientists grow diamonds from scratch in 15 minutes thanks to groundbreaking new process

Fuck deBeers

Blue_Morpho,

The article shows the diamonds are around 200nm in size.

someguy3,

Trying to size that: That’s 0.2 micrometers. Fine sand is 75 micrometers to 425 micrometers.

(1000 micrometers = 1 millimeter)

FilthyShrooms,

While not enough for jewelry, this is great for industrial applications, like abrasive grinding wheels or diamond tipped saw blades

Hawanja, to upliftingnews in Scientists grow diamonds from scratch in 15 minutes thanks to groundbreaking new process

This just tells me that diamonds are even more worthless.

Dorkyd68,

Folks like de beers hoard diamonds and jack up prices to make folks think they are more rare that what they really are. We gotta stop the cycle and buy lab grown or use an entirely different stone all together. Diamonds are for basic bitches anyhow

thisbenzingring,

Vintage sapphire is where it’s at. Nothing comes close to the magic blue of untreated sapphire.

GoosLife,

Wow, you werent kidding. What a pretty stone.

thisbenzingring,

I got my wife a antique sapphire ring to replace the engagement ring that was stolen in a burglary. When the sun hits that jem, it’s like staring into the deepest clear ocean. I was in the Navy and remember when we were coming to port in Honolulu. The water was the bluest blue I’d ever seen. Old sapphire gives me the same feels

sushibowl,

Recommend looking into moissanite also if you like diamonds but don’t want to support the industry. Very similar looking, better in some ways. And because it hardly occurs naturally at all, you can only buy synthetic.

qyron,

Use metal and artistic value, like this.

And if the pattern is open enough, sun ligh will leave the mark on the skin. It’s one very discreet way to keep the “mark” of who we love, skin deep.

i_love_FFT,
@i_love_FFT@lemmy.ml avatar

So you mean it might be possible to remove the wedding ring without leaving a mark, making it easier to hide that you’re married?

qyron,

What I wanted to convey is, if the mesh is fine enough, the pattern can get marked on the skin, leaving an elegant but discreet - shall we call it - love brand behind.

If you’re going to cheat, at least be bold enough about it and keep the wedding band on.

i_love_FFT,
@i_love_FFT@lemmy.ml avatar

Hehe, yeah I intentionally misunderstood your comment to make a joke…

With my so, we actually talked about getting a ring tattoo instead of an actual ring because of how we both never wear jewellery.

qyron,

Some good humored banter never hurt anybody.

That is the sole thing I draw the line. Scynical as it may sound, ink on skin, no. It feels as an ownership brand that can never be taken off or thrown away.

I personally dislike the notion of being permanent on another life. Either because things don’t work, people grow apart or someone simply dies, from misfortune, sickness or old age, nobody should be tied to another, in any way. Life should go on. Must.

And I’m happily and for a long time monogamous.

They always were – outside of engineering of course.

KeenFlame,

??? The strongest material available to us seems worthless to manufacture to you??

NeatNit,

they clearly meant diamonds as jewelry.

KeenFlame,

How?

NeatNit,

Compared to their artificially inflated price. They’re obviously useful in industry - mainly for their thermal conductivity and their hardness - but their price as a jewel is complete bullshit. They’re not rare at all in nature, but one company controls all of them and uses advertising to drive up demand and public perception.

KeenFlame,

Wow, I didn’t know that. Interesting.

9point6, to upliftingnews in A branch of the flu family tree has died and won't be included in future US vaccines

I wonder if lockdown was the final nail for it. I’ve been wondering if there were any variants of common illnesses we’ll never see again because it required more human cross contact to sustain its population.

ricecake,

Scientists first reported the apparent disappearance of Yamagata viruses in 2021. At that time, experts speculated that precautions taken to stop the spread of COVID-19 — such as masking and social distancing — had not only driven the overall number of flu cases to historic lows but may have completely snuffed out this type of flu virus.

Yup, basically. Everyone went inside, stayed inside, wore masks and got their vaccines. That was enough to kill a flu variant.

It would be wonderful if we could get staying home when you’re sick, wearing a mask if you might be sick and getting your vaccines to become the norm.

foggy,

We should do a winter lockdown every decade, just to keep it clean.

7U5K3N,

But won’t someone think of the shareholders!?!?

Gigan,
@Gigan@lemmy.world avatar

Or the kids? It was terrible for their education and social development. Hard to weigh the pros and cons there.

foggy,

Yes, very difficult

Millions of preventable deaths, or a cohort of misbehaving children. 🤔

Very difficult choice.

uberdroog,
@uberdroog@lemmy.world avatar

It had a huge impact on my kids. You are not wrong. The teachers were unprepared and often left to their own devices. I will tell you that older teachers and technology don’t mix. And it was like Christmas for all the kids who stayed in physical classrooms because now class was only 15 kids instead of 35. Sure, most of these kids are on their 4th round of covid, and my kids have still yet to get it, but it was two very important years that just went “POOF.” I need both hands and feet to count the grandparents I am personally aware of that are now KIA due to stubbornness. The whole time was a shit show, and we learned nothing from it. My oldest had some pretty sever issues due to the depression of the whole thing. Better than getting covid and checking out, yeah no question, but still f’d

Patches,

Don’t be silly. We learned plenty.

We learned those in charge are willing to throw your life away for “the economy”. This was doubly obvious is you were an essential worker. We also learned that “Yes people really will walk right up to a zombie and get bit against all advice everywhere”.

conditional_soup,

Bites don’t spread disease, it’s the vaccine that does. We’re having a biting party later at my house, be sure to brag about it on social.

AtariDump,

My oldest had some pretty server issues….

Send him over to homelabs; they can probably help.

leftzero,

Eh, kids’ future’s fucked anyway due to global warming and rampant enshittification, might as well sacrifice what’s left of it for the greater good. 🤷‍♂️

Pyr_Pressure,

That’s what happens when huge social change happens with absolutely no planning or preparation.

If we have 6 more years to prepare for another lockdown then I’m sure any of those issues can be more than accounted for.

jol,

I’m pretty sure covid 19 was a big fluke. I believe we will never, ever achieve that level of global cooperation again against a health crisis.

bitwaba,

We cooperated!?

jol,

To an extent, yeah. There was co-operation like we’ve never seen before. Even if only 40% of people wore masks and stated home, that’s an enormous feat of cooperation. But there was so much controversy around it, and the results were so unclear, that I’m 100% sure it will never happen again.

ricecake,

Oh, we will.
There was much the same type of kurfuffle with the flu in the early 1900s, down to crazed anti mask people.

njm1314,

For like one month and then the politics set in.

Anticorp,

Why do you think that? We’ve seen that level of cooperation at several points in human history.

jol,

Do you have examples? The only other I can think is the race to fix the ozone hole.

Fondots,

Smallpox eradication comes to mind, same with the ongoing efforts to eradicate Polio (we very well may see it by the end of the decade)

wabafee, (edited )
@wabafee@lemmy.world avatar

I think we been doing that a lot. I think the main point your saying is a quick reaction. For that to happen it seems the problem needs to be upfront you get to see the issue right away. Has an obvious solution with little to no downside. Needs to be global, multiple major countries affected especially the developed ones. It hurts every strata, the poor, the middle and the rich class most important. It just happened that COVID did just that. We manage to get a vaccine in 1 year that’s pretty amazing. Yet that is also why Ebola still only has 1 vaccine which was only recently approved in 2022. Somewhat those people who were carriers of the virus who went out of country kinda made it possible for us to have this vaccines for COVID.

conditional_soup,

Even then, the levels of global cooperation were, uhhhhhhhhhhhhh…

COVID was a much bigger deal than it would have been if China hadn’t tried to play fuck fuck games and pretend that there is no pandemic in Ba Sing Se. Instead, it took doctors getting in trouble with the state and blasting the alarm on social media (before dying of COVID) to raise the alarm that shit was going down. By that point, we were already a couple months into human-human transmission and the genie was already out of the bottle. Imagine if China hadn’t played stupid fucking games and immediately said “hey, guys, heads up, we’ve got something going on here” and collaborated with the international community on it from the get-go. We might have gotten a handle on it like we did with SARS.

I don’t think China was up to some shit and was trying to bury the evidence, I just think it was a mix of not wanting to disrupt commerce now (in exchange for disrupting a lot of commerce later, which is sort of the tale of global warming writ small) and not wanting to be ‘embarassed’ by another epidemic like SARS. I hope whoever was in charge of those decisions realizes what a stupid fucking decision that was, and thinks about just how many people they got killed and commerce they got disrupted (and reputation they destroyed for China).

These diamonds are too tiny for jewelry but I don’t care.

I want a diamond heat spreader for my CPU!

Khanzarate,

You already can.

Go bling up your heat spreading

Thassodar,

Everywhere I’m looking says sold out unfortunately. I’ve been using Arctic Silver for over a decade with no issue though, but I’m curious.

ASeriesOfPoorChoices,

just epoxy a bunch together.

NeoNachtwaechter, to upliftingnews in Scientists grow diamonds from scratch in 15 minutes thanks to groundbreaking new process

One problem is that the diamonds grown with this technique are tiny

So the next we need is a way to shrink the women so that they fit.

Lemming6969,

Semaglutide

LemmyKnowsBest,

I’m on semaglutide, it makes me small but unfortunately for the lab-grown diamond industry, I’m still not microscopic.

LordKitsuna, to upliftingnews in Scientists grow diamonds from scratch in 15 minutes thanks to groundbreaking new process

Everyone always thinks the jewelry when they think of diamonds but I am excited for the prospects of what cheap lab-grown diamonds can do for manufacturing. Diamonds are electrically insulative and yet 10 times more thermally conductive than copper. There are a LOT of industries that would be VERY interested in that.

Hell, it would probably be useful in CPU substrate as well. Instead of silicon semi conductor doping if these could be made precisely enough you could use diamond for the insulation layers and gain that insane heat transfer efficiency to help with avoiding Hotspots. Maybe that’s too thin to matter that much not sure

Hugh_Jeggs,

Heavily used in the building industry too. Concrete saws, tile cutters etc, all expensive as fuck

Crack0n7uesday,

Diamonds are the hardest mineral known to humans, it’s what we use for all deep sea drilling and excavation.

ASeriesOfPoorChoices,

hyperdiamonds are harder still!

en.wikipedia.org/wiki/Aggregated_diamond_nanorod

Crack0n7uesday,

We’ll be using that shit to mine asteroids in the next few hundred years or less. Crazy when you think about how far science has been going.

cucumber_sandwich,

Silicon carbide is much more interesting for the semiconductor industry. With pure carbon there is a lot of lattice mismatch between diamond and single crystal silicon which introduces strain and defects, both of which reduce yield in chip manufacturing.

I have spent a great deal of time in forests (and still do). I have not experienced anything like this.

I would like to add to this. I spend at least 20 hours a week in forests, and have heard a lot of things. Never my name.

Handwashing, masking, distancing, and isolation when sick were simple yet effective behavioral measures taken by the population of the world which actively caused this extinction of the Yamagata lineage. We did it, collectively folks. Congratulations!

prettybunnys,

An extinction even we can be proud of!

Don’t forget smallpox! (Polio still has pockets where it lives, but no longer a threat to general world population)

And rinderpest in cows. Hope we can stamp out Polio and Guinea Worm soon!

Looking forward to a future when fake rhinestones are just kinda shit manufactured diamonds.

Super tiny is fine for the things diamonds are used for besides sparkling on fingers.

@dual_sport_dork@lemmy.world avatar
RamblingPanda,

You can already, and for quite some time. They claim to be superior to all others.

thisbenzingring,

I have a tungsten steel nozzle on mine and it’s been good for a long time, I imagine it’ll run forever. Does anybody have experience with the diamond ones? Are they worth the extra expense?

RamblingPanda,

I haven’t tried them myself but they have (at least in theory) a lot of benefits speaking for them.

You won’t wear them out, no matter how abrasive your filament is. At least until you print diamonds I guess.

Diamond conducts heat so much better than any other material you might make nozzles from it’s hard to believe. You might (or will) run your prints way cooler, or faster.

Several other things I won’t explain here because I have no idea and would have to make them up on the spot. But how cool would it be to print with a poly crystalline diamond nozzle? I bet you’d drown in panties.

Which could be a drawback.

thisbenzingring,

Looking into it, these are very fragile nozzles. Even more so than the ruby ones. The Tungsten nozzles are the true robust nozzle. It will wear out if you’re using filament with abrasive materials but it takes a lot to do it. I’m going to keep it in mind but probably won’t consider it

TurboHarbinger, (edited ) to upliftingnews in Scientists grow diamonds from scratch in 15 minutes thanks to groundbreaking new process

Similar conditions are employed in the method currently used to synthesize 99% of all artificially created diamonds. Called high-pressure and high-temperature (HPHT) growth, this method uses these extreme settings to coax carbon dissolved in liquid metals, like iron, to convert it to diamond around a small seed, or starter diamond.

Cool. I don’t know how expensive this process is right now, but it seems cheaper to do, at least on mass production.

Edit: I wonder if they could make a tether out of this thing.

hihi24522,

“Bender, be careful! Thats the ship’s diamond filament tether. It’s unbreakable!”

“Then why do I have to be careful?”

“It belonged to my grandmother.”

threelonmusketeers,

A tether for what?

TurboHarbinger,

For everything of course, from space exploration to clothing

Material science.

threelonmusketeers,

For a tether, I feel like you’d want something with a high tensile strength, like Kevlar or Zylon. Diamonds are very hard, but also brittle.

@emptyother@programming.dev avatar

I know I heard my name called occasionally as a kid. Clear as day but directionless, seemingly from very close to me. I figured its just a bug in a developing mind. But could also be that my mom got damn angry if I didnt hear her calling so I was always listening for it, and like the article describe, I picked up noise and the brain filled in the expectation.
