A nanometer = 10 9 meter
We are talking about the nano tidal wave . Not a single day passes without the press reporting on major innovations in this area. Large industrialized countries spend considerable amounts of money, around US$10 billion per year, on this field of study. This should have a positive effect on the economy and on employment [1].
Microelectronics and the steady miniaturization of components has become commonplace. Moore s Law (a doubling of the number of transistors for the same surface every 18 months) illustrates this idea. This also makes us think of the production of chips in laboratories. With their engineers and technicians in uniform, these laboratories can be considered as the technological cathedrals of our times. Microcomputers, microprocessors, mobile phones and MP3 players with a USB connection are available to the general public. For several decades now, this technology has been largely submicronic, and the idea of nanoelectronics was created in the laboratories. The current technological limits will soon be reached, even if ongoing innovations will push them beyond these limits. Emerging technologies such as carbon nanotubes will take over.
The nanoworld is the intermediary between the atom and the solid, from the large molecule or the small solid object to the strong relationship between surface and volume. Strictly speaking, the nanoworld has existed for a long time and it is up to chemists to study the structures and properties of molecules. They have learnt (with the help...
