Self-assembling 3D Nanostructures 176

Posted by Hemos from the constructing-our-future-atom-by-atom dept.
Roland Piquepaille writes "Chips holding 10 terabits of data? Copper as strong as steel? Ceramics tough enough to be used in car engines? All this will be true in five years, thanks to two new methods to create self-assembling 3D nanostructures. These methods used pulsed laser deposition to create layers of nanodots organized in a matrix. These arrays of nanodots are consistent in shape and size -- 7 nanometers with nickel for example. But the real beauty of these methods is that they can be applied to almost any material, like nickel for data storage or aluminum oxide for ceramics. These methods also reduce drastically imperfections, leading to future superstrong materials. Read more here for other details and an image of a single nickel nanocrystal, or nanodot."

          At the moment, "self assembling" means that we don't have to push the nanodots together after we make them. That's all. You still need to ablate a carefully prepared target with a laser to etch the structures we want.

          Personally, I'm excited about their solid state lighting idea.

          from the article The most interesting application may be the development of energy-efficient, low-cost, solid-state lighting. By creating a matrix of layers of varying sizes of nanodots embedded in a transparent medium such as aluminum oxide, Narayan can create a chip that glows with white light. Solid-state lighting would use about one-fifth the energy of standard fluorescent lighting and last for approximately 50 years.

          Looks like my LCD monitor is about to become obsolete: there's no reason why these solid state can't be made the size of a pixel and tied to active matrix display electronics. Maybe the us military might be able to replace their $30,000+ individual soldier helmet monocles which are currently using 5000 hour MTBF organic led technology with durable, bright and efficient nano-leds and save taxpayer money while we're at it.

      You'd probably need a good few layers of carbon atoms to make sure no oxygen, nitrogen or even hydrogen atoms sneaked in. Not forgetting the byproducts of cosmic rays. My guess is that the total mass of the casing / volume would exceed the density of the surrounding air.

      Buckminster Fuller has a similar idea, but on a much grander scale. He figured you could could create floating cities from ordinary steel. If you could imagine a geodesic polyhedron 2 miles in radius with steel pipes 2-3 metres in radius for the edges, the force exerted by raising the air temperature inside the pipes by just a couple of degrees would be enough to make the structure float in the air.

      The closest real-world implementation at present is a nyoln fibre airship, with helium gas for lift. Roughly, you get 1 Kg of lift for every cubic metre of Helium. For a 6x2 metre airship with 25 cubic metres, the weight of the skin is around 8 Kg, when inflated, and 25kg of lifting weight.
