Today is a rare technology without nano devices, and to guess about what is really a worthwhile event, but that pustyakovoy shumihoy sometimes not so easy. Meanwhile, there is a fairly simple, reliable and proven method:a mentally remove this most prefix nano and examine the physics of the phenomenon, while in the macro scale. For example, nanokirpich - the thing is certainly useful. But by itself nanokirpich - this is just a promising nanomaterial. And absolutely nobody - until it does not learn to do nanosooruzheniya. The same thing all these nanoparticles, nanoprovoda, nanotubes. Of course, even for their inventions had to make a lot of effort and spend a lot of time. But until nanomaterial does not turn into nanoizdelie, in the practical application plane talking about all these nanotechnology, only an empty jar of air. In the future, yes. Still, the ice a little touched. Scientists step by step how to master not only the production of nanostructures, but also has developed instruments to monitor nanoprostranstvom and tools to manipulate nanoveschestvom. One such device was namedni constructed in the laboratory of the British University of Sheffield (Sheffield University). Imagine the process of connection of conductors and other metal objects. To do this a long time ago thought a lot of different ways of welding and soldering. When it came on the conductors and structures to create chips with nanoscale device, the scientists decided not mudrstvovat archly, and a soldering iron to nanorazmerov scale. Experiments with nanopayalnikom held in Sheffield University Biverli Inkson (Beverley Inkson), Tony Kullis (Tony Cullis) and Yang Peng (Yong Peng), as they are told in detail in the latest issue of Nano Letters. The process of soldering nanoprovodnikov was quite similar to the action by using soldering iron and solder, conducted with conventional wires. For example, the ration of two gold nanoprovodnikov, contact the ends but not the entire length, controlled by means of an electronic microscope and produced specialized Autotransport. Touch the ends of gold nanoprovodnikov were peremknuty bridge from conducting a special alloy of tin and gold. Then, the bridge had been melted by Autotransport, which filed disruptive voltage pulses, sufficient to heat and melt the bridge. To demonstrate the capabilities nanopayki scientists spayali NANO floor of the four individual letters, composed of nanoprovodnikov gold 55 nanometers thick, the whole structure is placed on a silicon plate. It would seem, all just beyond nowhere. However, the lack of such simple and reliable technology greatly hinders the possibility of designing nanomaterials something before - like nanomikroshem. Technology nanopayki can now be easily scaled for use in flow-release of various products and modules, where nanopaykoy manufacturing nanoliniyah will specially trained nanoroboty.
