Nano-Sized Engineering!!!!!

    Scientists have developed a new microscope which can penetrate deep within materials and see details as small as a billionth of a meter without even using a lens.

   This new microscope was developed by physicists at University of California, San Diego by using a powerful computer programme to convert patterns from X-rays bouncing off materials into imager of objects as small as a one nanometre across, on the scale of a few atoms.

   Here's a example of superman's X-ray vision which allows him to look through walls to see the bad guys beyond, similarly, the nano vision is used to look at the different elements inside a material or to image viruses, cells and tissue in great detail.

   It has one of the most important applications that is, in nano-sized engineering.

   Astronomers use similar programmes to remove distortions from their images and even to sharpen the pictures sent back by the Hubble telescope, but the nano-vision technique is new.

   Researchers, to test the programme created a layered film made of the elements iron and gadolinium. Combined, the two magnetic materials crinkle into a series of magnetic domains that look like a maze or the ridges of fingerprints.

   Shpyrko mentioned by seeing and understanding how the materials self-assemble, you could create nano-production processes that are much more efficient than the current method of building materials atom-by-atom, Shpyrko said.

   Shpyrko also mentioned that by understanding magnetic materials at the nanoscale could lead to better magnetic data storage.

   X-ray nano-vision also helps to see inside the interface to diagnose the problem between the battery's electrodes and electrolyte degenerates when batteries degrade overtime. This helps to know how this happens or how to fix it inside the interface and solve the problem.

  Shpyrko made a statement that “With this microscope, we can actually look at this very difficult interface.”

  Thanks, making to forget of X-ray glasses by developing, X-ray nano-vision which helps to see tough interface. Great!!!!!
