C3.11 - NANOPARTICLES

1. NANOPARTICLES / NANOSCIENCE - TINY PARTICLES WHICH ARE BETWEEN 1 AND 100 NANOMETERS IN SIZE

2. NANOPARTICLES MAY HAVE PROPERTIES DIFFERENT FROM THOSE FOR THE SAME MATERIALS IN BULK. HIGH % OF THEIR ATOMS EXPOSED AT THEIR SURFACE MAKES THEM HIGHLY REACTIVE.

3. NANOPARTICLES MAY RESULT IN SMALLER QUANTITIES OF MATERIALS, SUCH AS CATALYSTS, BEING NEEDED FOR INDUSTRIAL PROCESSES

4. HIGH SURFACE AREA TO VOLUME RATIO, FOR SOLIDS, THE SMALLER ITS PARTICLES, THE GREATER THE SURFACE AREA TO VOLUME RATIO

5. EXAMPLES INCLUDE: BUCKMINSTER FULLERENE
