請問為什麼第一題是practicable 而不是capable><

are one billion nanometers in one meter, you can get an idea of how impressive this technology really is! Even though this fabulous technology has been around for almost 100 years, we have only recently been able to experience both its benefits and i cogmignal ovil Asqa niso I e maoney but also area Stopesugar have characteristics These days, nanotechnology is used primarily to make things stronger, stiffer, and smoother. Due to their tiny size, nanoparticles increase the overall surface a of an object, and that acts to give the object special properties However, nanotechnology is also used in the field of biochemistry. One possible of nanotechnology in the future is in the field of robotics. It might be feasible for tiny nano-robots, or "nanobots," to be produced that could easily perform tasks in a very small scale. Each of these nanobots would be so small that you would need a special microscope to see them. Because of their small size, however, a great deal of them DEST OF 90 MOBST U simple math, inc ped programa Cindy a button nose Qué oyes, would be needed to perform a task. furod One drawback to nanotechnology is that the structures are so small that they pose some health and environmental risks. Because of their size, they can float around in the air and enter our lungs without our knowing about it. The effects of this are not yet known, but in the future, if the use of this sort of technology becomes more common, some specialists believe that we may suffer from various illnesses.
