Nano world Technology of the Future By:- Munjal patel 09EE035
Meaning Nano means one billionth. Nanotechnology - Deals with moleculues between one and one hundred nanometers in diameter. Manipulating individual atoms and manufacturing from the bottom up.
History of Nanotechnology • E = mc2 • Atomic bomb • Biotechnology/Genetic Engineering • Quantum Physics • Nanophase materials
(A) a hand holding a computer chip. (B) computer chip (C) living cell placed on the chip (D) two nanocomputers beside the cell. (E) shows an irregular protein from the cell on the lower right, and a cylindrical gear made by molecular manufacturing at top left. (F) shows two atoms in the protein, (G) reveals the nucleus of the atom as a tiny speck. Nanotechnology Past and Present 35 xenon atoms spell out a familiar logo
A demonstration on the molecular level A nano-motor manipulated by two laser beams
NANO MATERIALS CONSIST OF • BUCKY BALLS • NANOTUBES
Positive Effects on Society Above: Nanomachines could allow for cleaner energy production Right: Nanomachines in the blood stream patrolling for viruses
Positive Effects on Society (Medical Applications) Nanomachines could travel through the bloodstream
The Future with Nanotechnology Left: A nano-gear Right: A nano-universal-joint
The Future with Nanotechnology Above: A nano-bearing Right: A “nano-factory”
If it falls into the wrong hands Genocide and ethnic cleansing (pictures from Kosovo)
Some Final Thoughts • Still a young science, but could take off at any time • Presents wonderful opportunities • Presents terrible opportunities
