What is nanotechnology? Pliz explain in detail.
Recently, government and private institutions have devoted substantial research into finding potential valuable uses at this scale, as discussed below.
How are nanotechnologies used today?
Despite views that nanotechnology is a far-fetched idea with no near-term applications, nanoparticles, nanopowders and nanotubes already play a significant role in industry, environmental remediation, medicine, science and even in the household. The majority of nanotechnologies commercially used today are based on such nano-sized p ...more
Nanotechnology comprises technological developments on the nanometer scale, usually 0.1 to 100 nm. (One nanometer equals one thousandth of a micrometre or one millionth of a millimetre.)
Carbon nanotubes are cylindrical carbon molecules with novel properties that make them potentially useful in a wide variety of applications.
Carbon nanotubes are hexagonally shaped arrangements of carbon atoms that have been rolled into tubes. These tiny straw-like cylinders of pure carbon have useful electrical properties
;Superior stiffness and strength to all other materials
;Extraordinary electric properties
;Reported to be thermally stable in a vacuum up to 2800 degrees Centigrade (and we fret over CPU temps over 50o C)
;Capacity to carry an electric current 1000 times better than copper wires
;Twice the thermal conductivity of diamonds
;Pressing or stretching nanotubes can change their electrical properties by changing the ...more
A nanometer is one billionth of a meter, roughly the width of three or four atoms. The average human hair is about 25,000 nanometers wide.
