Synthesis of nano-structured metals and alloys

There s Plenty of Room at the Bottom Talk given by Richard R Feynman, Nobel Prize in Physics 1965 at the annual meeting of the American Physical Society at Caltech on December 29th 1959 

The famous talk by Feynman was first published in the February 1960 issue of Caltech s Engineering and Science and has been made available on the web 

6 laser focus, 7 quartz window and lens, 8 mirror (oscillating or raster scanned), 9 laser pulses, 10 Nd YAG pulsed laser, 11 laser power density diagnostic, 12 cryostat, vacuum pump system, exhaust. 

In a review by Gonsalves el al. (2000), techniques for the fabrication of nano-structured materials are outlined. Synthesis from corresponding organo-metal precursors of nano-structured metals (Fe, Co, Ni) and alloys (Fe-Co, Pt-Pd, and special steels) are discussed and various methods considered such as thermal decomposition, ultrasonic irradiation, chemical vapour deposition, laser pyrolysis and reduction. 

The following micro-structural features are considered to be the main factors on which the properties of the nano-structured materials depend
