Nanotechnology: The road for a better future Prof. Uriel Levy March 2016
The Nano-concept is in broad use
but what is really Nano Science? Small is Different! Human Hair 100,000 smaller Molecule Nano size yields new materials, properties & functions
Nano Science manipulates atoms & molecules to create new tailored materials
Why Nano? Nano is the only multi-discipline directly addressing every one of humanity s challenges Energy Consumption Environment Communication & Computation Health Homeland Security
