- tripm, on 10/12/2007, -0/+2i wish apple would actually use this stuff on their nanos...
- Egoslut, on 10/12/2007, -0/+1Has anyone noticed that Eze Vidra on the side there is really the same guy who does Ali G?
- inactive, on 10/12/2007, -0/+1They've done stuff like this before (buckyballs, anyone?), so it's no surprise to me. I still dugg it though, because I'm nice like that :)
- trex, on 10/12/2007, -1/+2Damn, Apple has good marketing; my brain just equated nano with iPod Nano. Bastards.
That's pretty cool though. - Cyberdactyl, on 10/12/2007, -0/+1The real holdup with NT tech is the purity and manufacturing cost. Once that's ironed out, God only knows what will be done with it. Parachutes that fit in your hip pocket, Aircraft weight reduced by 80%, impregnated muscle fiber. . .-never pull or rip a tendon again. Solar sails in the tens of square miles that weigh a couple hundred pounds. Clothes that never wear out. It's 52x times stronger than carbon steel. Not twice as strong (Titanium). . . or 5 times (Kevlar). . . but 52 times! Can you imagine lifting an SUV with a nanotube cord the diameter of sewing thread?! Or the bulletproof layer in a vest being no thicker than a women's scarf? It reminds me of a material used in one of Larry Niven's novels that make up a 'stasis sword'. Basically the ultimate cheese cutter. Imagine a bowed filament 1/10th as thick as a human hair pulled tight with a couple hundred pounds of tension passed across a human body. . clean cut, no resistance = ouch.
- Scorcho, on 10/12/2007, -1/+2Does this mean diamonds aren't a girls best friend anymore?
- Bromskloss, on 10/12/2007, -0/+1I don't get the title. Who said there was nothing harder than diamond?
- wonderboy, on 10/12/2007, -0/+1Diamonds actually don't last forever. Eventually they turn into carbon. Just a fun little fact for whoever said diamonds are forever.
- gwax, on 10/12/2007, -0/+1They're using the words hardness and toughness interchangeably, which is wrong, they apply to different material properties. This confusion makes me wonder if they aren't confusing other key words. No digg.
- duke_nate, on 10/12/2007, -0/+1"BUt nano technology produces something new right? Or am I wrong? Are diamonds still the hardest natural substance?"
Yes diamonds are still the hardest in nature. We make the nanotech, so it doesn't count in that aspect. - Eugenis, on 01/12/2009, -0/+1Diamonds: A Globes Best Friend! - Celebuzz - from diamonds news:
http://jewelry-newsline.com/diamonds.html - cwcentral, on 10/12/2007, -0/+1Article doesn't have enough info. Better info on wikipedia or britannica.
Also, if we're talking nanotech, you can say most stuff is C60-derived, therefore, it's not stronger than a diamond, but the same! (they're all carbon-based)
The neat thing is humans can improve on the lattice structure (of nanotubes for instance) for specific purposes. - Detour, on 10/12/2007, -0/+0Diamonds aren't forever, but debt is.
- inactive, on 10/12/2007, -0/+0Looks like Borat's blog.
- munboy, on 10/12/2007, -0/+0Has anybody noticed that this is super old news? slashdot and digg both had this stuff a month or two ago.
- Xinex, on 10/12/2007, -0/+0I suppose that's cool even though they've been doing this for a while now. But since it's made with nano technology it has to be awesome, right? [sarcasm] It's probably $1000 per square millimeter, too.
- MWWLSE, on 10/12/2007, -0/+0Ah yeah Viruz, beat me to it by a minute.
- dpk87, on 10/12/2007, -0/+0very old.
- ramsinks.com, on 10/12/2007, -0/+0Congrates Science!!!
now what..?
(this probably just cost me money) - petertgreen, on 10/12/2007, -0/+0clearly the iPOD nano is not made of nano... as my nano is covered in scratchs after 2 months... while my PSP after 8 months has but one very small scratch. go figure!
- ConceptJunkie, on 10/12/2007, -0/+0ksgant: I think /. ran the link about 5 years ago. I don't recall where the original story was. There is so much stuff being published by newspapers who do little or no fact checking these days (although I would be inclined to trust the Jersalem post).
I never said anything about it "being kept from us". I said I didn't believe the story. Please, keep your diagnoses of paranoia to yourself.
That this story is reported in non-science news alone is reason to question it. If SA or Nature or something publishes it, I'll be less skeptical. - jpyun, on 10/12/2007, -0/+0WTF wonderboy? Diamond IS carbon. Ever heard of an allotrope? I guess not.
- inactive, on 10/12/2007, -0/+0they have been making things harder than diamonds since th early 90's
- paladin, on 10/12/2007, -0/+0But how does it compare to scrith?
- ConceptJunkie, on 10/12/2007, -0/+0I recall seeing a news story a few years ago that Israelis had developed a quantum computer that rendered encryption obsolete. This story reminds me of that story, although it's a little less far-fetched.
About the time they were describing little "vacuum cleaners" sucking the cholesterol out of your blood, I had to wonder if this was just another bogus story snapped up by some reporter who doesn't know anything about what he's writing.
Maybe it's legit (the QC one was clearly bogus from the get-go) but it seems kind of iffy, IMO. - 40-Dan, on 10/12/2007, -0/+0But in 10 years, will you be able to cook on it?
- thekak, on 10/12/2007, -0/+0BUt nano technology produces something new right? Or am I wrong? Are diamonds still the hardest natural substance?
- viruz, on 10/12/2007, -1/+1Old news , first reported on August, 30, 2005 at http://www.newscientist.com/article.ns?id=dn7926

http://www.jpost.com/servlet/Satellite?cid=1132475677365&pagename=JPost%2FJPArticle%2FShowFull - oahost, on 03/23/2008, -0/+0It is linked to something unrelated.
- D4r7h3v1l, on 10/12/2007, -0/+0TECHNION! TECHNION!
My father's alma mater! - deadkenny, on 10/12/2007, -0/+0"Diamonds actually don't last forever. Eventually they turn into carbon. Just a fun little fact for whoever said diamonds are forever."
They don't turn into carbon, they are carbon. Diamond is nothing other than a crystal form of carbon.
In fact this nano stuff is also carbon (http://en.wikipedia.org/wiki/Aggregated_diamond_nanorods)
Diamond however does eventually decay into graphite, which is just carbon again, but apparently it would take an extremely long time to do so (talking billions of years) if just left to decay on their own. They are however capable of being burnt at a high enough temperature and are relatively easy to break through impact and sheer forces. - ForbesBingley, on 10/12/2007, -0/+0This is quite old news.
First broke about a month ago.
Still interesting, but I'm not diggin' it... - urmudda, on 10/12/2007, -0/+0Diamond is still the hardest natural element
- Bluezdood, on 10/12/2007, -0/+0But, are they harder than my poops? Whew brotha!
- inactive, on 10/12/2007, -0/+0I love Ali G!
btw OLD news - futoshi, on 10/12/2007, -0/+0How do you dispose of nano material garbage?
- grieks, on 10/12/2007, -0/+0Old news.. so old... old!
- sudoman, on 10/12/2007, -0/+0what's the index of refraction? If it's higher than a diamond's, then it is a girl's new best friend. ; )

"Damn, Apple has good marketing; my brain just equated nano with iPod Nano. Bastards.
That's pretty cool though."
The twist is this is what Apple are gonna coat their new iPods with to stop them scratching so bad (that's a joke btw) ;o) - hochy0lora, on 10/12/2007, -0/+0this could be extremely useful
- aaalex32, on 03/31/2009, -0/+0Diamonds are the hardest substance,I wish I could have one Diamond Bracelets!http://www.ultradiamonds.com/jewelry/categories/di ...
- Jibberish, on 10/12/2007, -0/+0How long until DeBeers monopolizes the market with these things?
- gukid, on 10/12/2007, -0/+0Some things once made... cannot be "un-made"...
Scary thought? - aaaaliyah8, on 03/30/2009, -0/+0Yes, I agree with you, diamonds are still the hardest in nature but its truth still women’s like Diamond Necklaces too much. http://www.ultradiamonds.com
- Motta, on 10/11/2007, -0/+0Actually carbon, super-compressed, can change its molecular structure both making it much harder than diamond and at the same time eliminating all the tricky nano-business, making for signifigantly decreased production prices. I've never seen the stuff but i speculate it would be shiny black making it not a canidate for girls best freind.
- paladin, on 10/12/2007, -0/+0Oops, the link:
