Ultrananocrystalline Diamond Film 160

Posted by timothy from the recognition-at-last dept.
buzzlightyear writes: "The Sept. 12 Chicago Tribune has an article headlined "Sparkling discovery for science" , about the development of ultrananocrystalline diamond film. The scientist who developed this, Dieter Gruen, started by experimenting with fragmented buckyballs, and had proven its properties in 1994, but he is only now receiving recognition and an award from the Materials Research Society. Preliminary tests show that ultrananodiamonds are 1,000 more wear-resistant than silicon, and 1 million times denser than conventional crystals. This makes them a practical base material for micromachines and other devices that had only been theoretically possible before. Maybe this will mark the real beginning of Neal Stephenson's The Diamond Age."

  • Pretty exciting stuff, until you get halfway down the article and discover that they made it with buckyballs. Doen't eople realize that there is no large scale (ie greater than a few hundred molecule at a time) process for making these things, after more than 15 years! Sure they're amazing, but at thousands of dollars a milligram, there isn't much use. When we can either a) find a large scale production method for either fullerenes or nanotubes, or b) make a proper nanoassembler, that will be one thing. Until then, all this talk is even less meaning full than those 1950s Popular Mechanics articles that proclaimed flying cars for all within the decade...

    If what I heard is worth taking at face value, then I think the sad little info releases about 'recent' technological advances we see available for public consumption are the result of an orchestrated control over the time line on which the general public is kept in regard to scientific advancement. As far as I can figure, we're at LEAST thirty five years away from having access, (both physical and psychological), to the kind of tech a select few currently take for granted.

    Kinda sucks.

    One of the main applications in the instance of this fine crystaline stuff, (which was not even mentioned either in the article or on Slashdot), was in the area of battery architecture.

    If any of this is true, then most of us here at Slashdot are playing in tune like a bunch of damned lemmings to a timed beat metered out by others. Feel the joy.

  • I love Heinlein. His books changed my life. I idolize him. But you do seem somewhat deluded.

    Early in his career he wrote very wholesome books - which were Juvenile Fiction (include Starship Troopers, which movie really depressed me) meaning they were written for kids. Which is great, especially considering the reading level is above most adult books these days. Maybe you only read his little kids books.

    Later on he wrote fewer juvenile books, and more adult ones. (There is some cronological overlap between the categories. But the books are usually labeled.) These were not "wholesome" in any way. Juvenile or not was based largely on the applied themes.

    I'd agree he had issues. Almost every adult contained orgies of some sort, usually with all the protagonists, and many contained various other "free thinking" sexual practices. I doubt he ever had anyone punished for incest. People who were abusive were likely to get punished, although his books were realistic enough that this didn't always happen.

    But I love him. He was smart and experienced. He was dead-on about most people, imho. And he was honest about things. And I agree that he hit to the heart of a lot of people by being honest.

    Another recommendation: The Sensuous Dirty Old Man, by Dr. A (Issac Asimov) I was very surpised when I read this book. I've since decided that good science fiction writers are smart and have few delusions, and that only delusions can keep you from being a sick bastard.

  • Actually a couple years ago, I was reading about somebody who wanted to coat the blades of various tools with some sort of vaccuum deposited diamond film (possibly this... I don't know too much about this process, the think i was reading also involved vaccuum chambers and heavy hydrogen and bombarding stuff with microwaves... didn't sound like too practical a process on an industrial scale).. That was in 93 or so, so it was probably something different... This sounds cool though =:-)
    If I am not mistaken, the process involved some CO2 atmosphere in an oven, and bombarding a plate glass with carefully phased ultrasonic waves. Within hours, the glass was coated in a very thin but scratch-proof diamond film.

  • Use this process to coat the rings and cylinder wall for my trucks engine. While there at it, coat everything that rubs or has water running through it. With its low coefficient of friction, and long wear, the engine will double in horsepower, get twice the mileage and practically never wear out (with proper maintenance).

    My car has a truck engine in it (I have an '89 240SX, which has the KA24E motor. It's the same as the Nissan pickup from the same year) and it DOES get twice the mileage. Well, maybe not twice, but I pick up 30 mpg freeway. No joke.

    You'd get a better increase in performance at a cheaper cost by just using buckyballs as lubricant.

    Also, where do you think cars go when you get rid of them? Someone else buys them. If they're totalled, they get crushed, and recycled, and made into - Yep, you guessed it - cars, among other things.

    If you're really worried about using this technology to improve your environment, figure out some way to use it to improve battery life, so we can all drive electrics. While you're at it, figure out a way to use it to make high-power photovoltaic cells...

    Which gets at the real beauty of Gruen's work. Now these astounding, tiny machines are much closer to reality than ever before, at a time when there is an intense international push to develop these microscopic machines--known as MEMS.

    MEMS, Microelectromechanical systems, could very well be a revolutionary technology with such applications ranging from tiny actuators for robots or satellites to small, efficient inductors in radio-frequency integrated circuits. While this article implies carbon-diamond MEMS could be revolutionary, it gives no indication they'd be practical.

    Remember, silicon (and all semiconductors, including carbon) has a diamond structure, so presumably using these buckyball carbon diamonds would be better. The problem is, how would we fabricate them cheaply?

    The key reason silicon micromachines dominate the market for things such as automobile airbag sensors is because they are able to leverage already highly advanced silicon fabrication technologies originally developed for integrated circuits. No such technology exists for pure carbon and developing one would cost an unbelieveably large amount of money and take many years. There had better be some compelling reason for us to do so.

    Many times technologies "better" than silicon have come out only to remain niche technologies. A good example is III-V semiconductors such as Gallium Arsenide. While they are indispensible for lasers and such, they are not used for integrated circuits nearly as much as silicon, because they are so damn expensive. Their current main use, RF power amps and fiber-optic receivers, is quickly being impinged upon by advanced silicon CMOS technologies.

    My point is that this discovery is pretty interesting, but it is far from "revolutionary". Until someone comes up with a killer app that provides a compelling reason to justify the expense to develop this further, I'm going to keep my money on silicon-based micromachines.

    Somehow I think you (and severaly other posters) completely missed the point on the Neo-Victorian society. One of the common themes (if you can count two books) in Stephensons work is the idea that organized goverments will ultimately break down in the face of technology. In both Snow Crash and Diamond Age, the result is a large number of smaller goverments formed around some sort of shared ideal or commercial culture. In Diamond Age, it just so happens that one of the main groups in the book are a set of people organized around a shared ideal based on a Victorian society. This is not a prediction that nano technology will morph americans into neo Victorians, it is just an example of one possible group that may form in a world where large governments based on geographical borders no longer make sense.

  • Another interesting application of diamond films is their use in constructing gamma ray lasers.

    It's hard to make such a device, based on the fact that there is not enough energy in an electronic transition to make gamma frequency emmisions. So, instead of electonic transitions, you rely on *nuclear* transitions. You have to pump the nucleus of an unstable isotope with x-rays to acheive population inversion inside the nucleus.

    Anyways, you also have to imbed the radionucleide in a matrix, namely thin film diamond. I think the gamma ray laser project was one of the last SDI funded research projects in the 90's. I think they got the whole concept to work, but I'm not sure if it got developed further.

    Nevertheless, this exact technology played a pivotal role in the storyline. Now that it is quickly becoming science fact instead of science fiction, I'm interested in re-reading the book. Perhaps old Don knew more than it seemed at the time.

So a spectacular increase of density would mean that the same area would have to sustain a really, really bigger weigth. Therefore punching a hole in whatever material it may be.

    That would be funny. Kind of like Daffy Duck's Anti-disintegrating Vest, which wont disintegrate (or protect the owner from disintergating, either!)

  • But what a derivative piece of generic "cyberpunk" tripe! I couldn't figure out why anyone got excited over that piece of crap. "Lets see: two parts Neuromancer; one part Shadowrun; mix until lumpy and stale."

    At what point does this copy Neuromancer? I've read both of these books several times and I can't see your point. Neuromancer was dark and brooding. Snow Crash was actually rather upbeat. There stories weren't even really similar except for them both falling into the Quest theme of stories (if that's your point then Neuromancer is ripping off the Lord of the Rings triology). In respects to Shadowrun, it is itself a mix of several different styles and is meant to be, it's a game. As for lumpy and stale? This was the book that many critics give credit for breathing life into what was seen as a dying genre. And it flowed quite well, except for the ending but I'm willing to forgive it due to the rest of the book. And I hardly see how it was generic. The Shadowrun books... that's generic tripe.

    As for the rest of his work, go read Cryptonomicon (it's finally in paperback) or Zodiac (really good and one of his first if a bit hard to find). Read Diamond Age but be prepared to be confused. It's pretty dense with the language at points and the plot jerk a little every now and then.

    To sum up, I must say that I've never read a Stephenson book that I disliked. And Diamond Age is worth it just for the line near the end about the barbarian princess... I still get shivery reading it.

  • I'd hardly call such novels as Revolt in 2100, Starship Trooper and The Puppet Masters juveniles.

    I don't know about Revolt in 2100 or Puppet Masters but Starship Troopers was intended to be a juvenille, albiet for older children (10 and above). Kinda hard to believe when today's juvenille literature is (for the most part) one step above moronic.

    Yes, but at least that money would be going to some nano-technology buckyball-growing cool-ass research group, instead of going to bankroll more civil wars in Africa. How many people died for that jewel on your honey's finger?

  • Ideas like this have been kicking around for years. The real problem isn't getting the carbon/diamond on the blade edge, it's keeping it there. Diamond is inert, so it doesn't like sticking to things, so it usually "rubs off" the substrate (metal, in your case) quickly.
  • His books suck!

    They have little plot. Underutilize characters that he sets up as main characters, overutilizes background characters. Follows no coherent pattern in the storyline.

    He may do his research, but I would wish to God (not Stephenson) that he would read the other God's book --Sol Stein's Stein on Writing. Maybe that would help him out.

  • if volume [decreases], density increases.

    ...if the mass is being held constant, which it obviously isn't. The crystals are smaller because they contain a million times fewer atoms, not because they contain the same number of atoms packed a million times tighter.

  • ...with advanced degrees in physics, chemistry, and hyperspace geometry. Froin-glaven!

    In all seriousness, obvious when you know what regular diamond crystals are like because the increased density version would involve collapsing the electron shells, which is frowned upon among civilized chemists (only those boorish astrophysicists would dare such an offense against the proper state of matter).

  • "Maybe this will mark the real beginning of Neal Stephenson's The Diamond Age."

    I'm a big fan of Neal Stephenson, but a bigger fan of Sir Arthur C Clarke. He should get some credit for predicting that we are entering (have entered?) a "Carbon Age" [bbc.co.uk]. Diamond-based materials are going to be a minor material of the future, and will not be as important as the major advances in other carbon-based materials. We've already seen buckyballs and carbon-fiber... I don't think anybody will disagree that we're on the verge of some exciting times as far as Carbon is concerned...

  • 1 million crystals in Gruen's diamond film can fit inside the crystal produced by conventional methods

    Which means that the crystals are a million times SMALLER, not denser.

    Well, a million times smaller by volume, but a hundred times smaller by linear measure, which is a more rational measure of this sort of thing. For example one of the things that is interesting for this sort of stuff is flatness, which is a (very crudely) related to the size (and size distribution) of the crystals.

    Of course "One hundred times..." doesn't sound as good as "one million times...".

  • while that may be possible, I would have to wonder what would happen if it is a fully sealed tooth decay preventative device -- if the teeth need air from the outside, this could cause weird decay.

Like a literal rendition (through time travel and paradoxes) of the comedy bluegrass ditty "I'm My Own Grandpaw".... I could go on, but I won't.

  • My car has a truck engine in it (I have an '89 240SX, which has the KA24E motor. It's the same as the Nissan pickup from the same year) and it DOES get twice the mileage. Well, maybe not twice, but I pick up 30 mpg freeway. No joke.

    Bzzt. Wrong. Thanks for playing. I owned an '85 Nissan Pickup up until just a few months ago. I got around 20mpg highway, even though the engine was so worn that it had gotten tight to the point that the starter wasn't strong enough to turn it over (had to assist the starter by popping the clutch on a downhill grade. A real bitch when it's raining.) So you get 50% more mpg from the same engine in a sleek, low-slung sports car than I get running it in a high-riding, blocky, 4x4 pickup. I'll give you that, but it doesn't negate my point that the same engine would have improve performance, wear longer an use less gas with harder/slicker bearings and rings. All you've said is that a small sports car requires less energy to push than a larger truck.

    You'd get a better increase in performance at a cheaper cost by just using buckyballs as lubricant.

    Bzzt. Wrong again. You have to periodically replace combustion engine oil, not because it is worn out as most people seem to think, but because it gets full of trash from the combustion process. Most modern oils would last for 20,000 miles in a contemporary engine, but since it's second calling is to carry soot and grit away from the rubbing parts , you have to replace it when it gets saturated. Synthetic oils are already very expensive. Who could afford to replace oil ever 3k to 7k miles with an exotic lubricant like buckyballs? You may get better performance, but you definitely won't get it cheaper unless you devise a manufacturing process less complicated than "1)pump crude out of the ground, 2)crack it, 3)put it in bottles."

    Also, where do you think cars go when you get rid of them? Someone else buys them. If they're totalled, they get crushed, and recycled, and made into - Yep, you guessed it - cars, among other things.

    I'm sure you have a point hidden in there somewhere. My point is that the car must eventually die. My wife's Volvo died two weeks ago (threw a rod). Yes, it'll be recycled, but the process of doing that is very energy intensive. Wouldn't it be better for the environment and her wallet if the car just worked for several more years.

    If you're really worried about using this technology to improve your environment, figure out some way to use it to improve battery life, so we can all drive electrics. While you're at it, figure out a way to use it to make high-power photovoltaic cells...

    How the hell would technology that improves the mechanical properties of sliding or rolling surfaces be used the improve the electrical characteristics of batteries or PV cells? Use the tech to coat the bearing of an electric car and it will get more miles on a charge, but that is about the only use and that would apply to any engine technology used. Coating the bearing in the power plants generator would drop the friction there, thus lowering emissions at the power plant.

  • Maybe
    this will mark the real beginning of Neal Stephenson's The Diamond Age."

    Well, maybe yes and maybe no. We have to wait until next year for the 2001: A Space Oddessy prediction to come true, then in 2010 Jupiter explodes and becomes a star.

    But wait, don't get too confused, at the end of 2033(isn't that the last of the trilogy?) we discover that DeBeers has been keeping all of the diamond matter a big secret.

    Anyway, we have to wait until we have enough diamond to build all the stuff Clark wrote about first and then Stephenson piled on.

    Besides, I don't really see how some useless upgrade to miniature cars actually affects science. After all, all Micro Machines are nowadays are a crappy standover of the 80's, somehow still alive today... though I'm glad we don't have to listen to that dude in the Micro Machines commercials talk at 300 kilometres per hour anymore...

  • Using the crystals he produces, I could see making a diamond fractal blade, ala Gibson. It wouldn't have infinite recursion, but it could recurse from an inches-long visible outer pattern down to the nano-scale of his crystals. It would be far sharper than any conventional blade.
