Nanotechnology

 

Materials Science deals with the study and preparation, crystal structure and physical and chemical properties of materials, and how to adapt to specific uses. Its aim is to study the interplay between materials and their properties, consolidating and expanding both experimental and theoretical knowledge.

Nanomaterials are materials with smaller morphological properties than one micron in at least one dimensión 0.1A. Despite the fact that there is no consensus on the minimum or maximum size of a nanomaterial, some authors restrict the size of 1 to 100 nm, one logical definition would place the nanoscale between microscale (1 micrometer) and atomic / molecular scale (about 0.2 nm) .

Nanotechnology uses objects or very small devices. Nanomaterials are an increasingly important nanotechnology product. Containing nanoparticles of a size less than 100 nanometers in at least one dimension.

Nanomaterials are now used in fields like health, electronics and cosmetics, among others. Their physical and chemical properties often differ from those of other bulk materials, which require specialized risk assessment. This should cover the risks to the health of workers and consumers, and potential environmental risks.

This is currently carried out case by case, but it must updating the risk assessment methods due to more widespread use of nanomaterials, especially now that are doing their way to reach to consumer products.

Among the proposed projects is considered: The study and development of biomaterials for remediation of contaminated soils in landfills.
