Definitions
Nano-objects (particles, fibers, plates, tubes,...) are entities with at least one dimension is smaller than 100 nanometers. These entities are the basis for the formation of nano-structured materials on the surface or in volume. They are passive or active as nanodevices. This website deals the risks associated with nanomaterials without covering the wider field of nanotechnologies.
Cartoons Episode 1
This approach is based on the atom assembly, molecules or aggregates. The approach uses chemical (sol-gel technique, vapor phase reaction) and physical (laser pyrolysis, micro-waves,…) elaboration processes.
Two approaches for elaboration of manufactured nanomaterials [M. Ricaud et al., INRS ED 6050 (2012)].
