3. Nanotechnology is the understanding and control of
matter at the nanoscale.
Nanoscale is scale at dimension between approximately
1 and 100 nanometers.
4. Matter such as gases, liquids, and solids can exhibit
unusual physical, chemical, and biological properties at
the nanoscale. Some nanostructured materials are
stronger or have different magtetic properties
compared to other forms or sizes or the same material.
Others are better at conducting heat or electricity.
5. Professor Norio Taniguchi coined the term
nanotechnology. It wasn’t until 1981, with the
development of the first scanning tunneling
microscope that could «see» individual atoms, that
modern nanotechnology began.
6. Something as small as an atom is impossible to see with
the naked eye. The microscopes needed to see things at
the nanoscale were invented relatively recently – about
30 years ago. One scientists had the right tools, such as
scanning tunneling microscope and the atomic force
microscope, the age of nanotechnology was born.
7. Nanoscale materials were used for centuries. Alternate-sized gold
and silvers created colors in the glass windows of medieval churches
hundreds of years ago.
Today nanotechnology used in medetsine.
At Rice University have demonstrated the use of the welder to the
flesh, to fuse two pieces of chicken in one piece. Two pieces of meat
positioned in the focus to each other. Green liquid was poured along
the seam. Infrared laser was held along the seam and welded the
two sides together. This technology can decide difficulty. Welder
flesh can perfectly brewed artery.
8. Nanotechnology is not simply working at ever smaller
dimensions, working at the nanoscale enables scientists
to utilize to the unique physical, chemical, mechanical,
and optical properties of materials that naturally occur
at that scale.
