Broad Family of Carbon Nanoallotropes Classification
Classification of Nanomaterials for Commercial Purposes. In addition, a classification scheme was developed for nanomaterials based on their chemical composition. this scheme could help to identify which classes of nanomaterials, this is the reason that computing is so powerful and easy these days. that kind of natural nanotechnology is about ten times smaller than some of the smallest synthetic nanotechnology that has been prepared until now..
WHO GUIDELINES ON PROTECTING WORKERS FROM POTENTIAL
Nano- and Biomaterials Compounds Properties. Based on their morphologies, nanomaterials are generally classified as materials with either high- or low-aspect-ratio nanoparticles. nanotubes and nanowires with various shapes, such as helices, zigzags, and belts, are examples of high-aspect-ratio nanoparticles [ 6 ]., classification of nanomaterials nanomaterials have extremely small size which having at least one dimension 100 nm or less. nanomaterials can be nanoscale in one dimension (eg. surface films), two dimensions (eg. strands or fibres), or three dimensions (eg. particles). they can exist in single, fused, aggregated or agglomerated forms with spherical, tubular, and irregular shapes. common types.

EVALUATION OF POTENTIAL SAFETY (PHYSICOCHEMICAL)
Classification of Nanomaterials Nano‐ and. Nanomaterials have attracted much attention from academic to industrial research. general methodologies are needed to impose architectural order in low-dimensional nanomaterials composed of nanoobjects of various shapes and sizes, such as spherical particles, rods, wires, combs, horns, and other non specified geometrical architectures. We have made use of these terms and symbols in the classification and systematization of a wide variety of low-dimensional nanomaterials. some representative examples are listed in table i . detailed discussions with regard to their structures, properties, and device applications can be found in вђ¦.
Of techniques to produce nanomaterials depends on whether the nature of the pattering is chemical or physical or the process is parallel or sequential in time [1,2 5-7]. nanomaterials are of two types; first ones are natural e.g. butterfly wing scales, milk, blood etc. second ones are artificial/synthetic e.g. carbon based nanomaterials fullerene, carbon nanotubes, graphene , graphene oxide, graphene quantum dots etc. on the basis of applications these materials can be categorized as functional materials (at least one dimension is in nanometer range and have
