    How These Microscopic Diamonds Are Going to Shape the Future
    “No doubt you're already familiar with the many ways graphene promises to save us all, but there's another (so-called) miracle material out there vying for your attention-and it's sparkly, to boot. Say hello to the latest and greatest substance to kick science's ass straight into the future: the nanodiamond.”
    Molecular-sized fluorescent nanodiamonds
    “Here, we show that isolated diamond nanoparticles as small as 1.6 nm, comprising only ~400 carbon atoms, are capable of housing stable photoluminescent colour centres.”

    I'm not sure how expensive it is to reproduce a diamond in a lab, but after hearing all its properties, it looks like it is overrated. This feels like the Tulip mania back then. No wonder diamonds aren't saving anyone, and probably could be replaced. www.barrons.com/articles/the-real-story-of-the-dutch-tulip-bubble-is-even-more-fascinating-than-the-myth-youve-heard-51557666037

    Wait, diamonds are not electrically conductive but is the best thermally conductive solid known to man? Well ever since the early days of thermal paste, some manufacturers have tried mixing grinded metals to their thermal paste to increase the thermal conductivity. But it also has a bad side effect of being electrically conductive so if you over apply it on your heatsink, you risk it touching the contacts on the mobo and frying your board. Now, we can grind artifically created diamonds to mix them in with thermal paste to increase thermal conductivity without the risk of frying your shiny new mobo and cpu.

      You can buy the equipment to make a heatsink diamond. It will be much cheaper than order a company to make one for you.

    • Electrofizz
      Electrofizz 2 years ago +4

      Probably cheaper than you'd think. It'd be like normal thermal paste but with diamond dust in it, and diamond dust is much much much cheaper than pretty diamonds because they are made from ugly diamonds that are not worth anywhere near as much

    • BloodyRain2k
      BloodyRain2k 2 years ago +1

      As Xan said, industrial made ones are cheap and will become even cheaper over time, so in a few years we might get actual diamond heat sinks, but before that we will have a lot of fake shit because that's how we roll.

    For the jewelry, it's possible to do a similar effect with plastic. Without the high value of the diamonds, the people wouldn't give so much importance if someone give or lost.

    the only reason they aren't more popular in building ect is because that would cause a problem with supply and demand which would make diamonds not valuable which would put julery makers out of business which would cause them to need new jobs which would cause a need in more jobs which make the pay go down because more people are working and that causes people to run out of money which causes people to lose there job then it is just a cycle from there
