Note: Nanoscale crystals, which are cut very frequently, are powerful catalysts for chemical reactions. And  the unusual shape of the crystals causes the atoms of the nanocrystals to align themselves in an uneven way to increase reactivity.

Nanocrystals are substances whose constituent particles are arranged in three regular directions. If the atoms or ions manufacturer regular way  to learn something  crystal  is  (ie a periodic arrangement of atoms in the crystal due to three dimensions, internal order). Crystals characterized by well-developed crystalline faces (external surfaces) are described  as  . A crystal is made by arranging atoms and groups of atoms in regular patterns, for example at the corners of a cube or rectangle prism  . The basic arrangement of the atoms that describes the crystal structure is determined. This cell is called a unit. The crystals must have  a balanced charge  . This means the amount of negative charge  It should  be compensated with the same amount of positive charge.



A nanocrystal is  a material particle having at least one dimension smaller than 100 nanometers, based on quantum dots  . (A nanoparticle) and consists of atoms arranged in either single or polycrystalline . The size of the nanocrystals distinguishes them from larger crystals. For example, silicon nanocrystals can emit efficient light, while bulk silicon does not and can be used for memory components. When embedded in solids, nanocrystals may exhibit much more complex melting behavior than conventional solids and may form the basis of a particular class of solids.  They can act as single-domain systems (intra-system volumes with the same atomic or molecular arrangement) that can help explain the behavior  of macroscopic specimens of  the same material without the complexity and other  similar particles  . Semiconductor nano-crystals  with dimensions less than 10 nm as well as quantum dots  are described  .



Conclusion : 

Nanoscale crystals, which are cut very frequently, are powerful catalysts for chemical reactions. And  the unusual shape of the crystals causes the atoms of the nanocrystals to align themselves in an uneven way to increase reactivity.
