New dimensionality classifications of nanostructures

Properties of Nanostructures: Data Acquisition, Categorization, and Evaluation

“…The number of classes defined with this classification is essentially limited. For example, when only three structural elements are used, the number of classes is no more than 36 (Pokropivny & Skorokhod, 2008).…”

“…The higher levels define an object by four criteria: dimensionality; external and inner structure; chemical origin; and properties and behavior. Notably, as distinct from the schema of Pokropivny and Skorokhod (2008), the number of nanoscale sizes is accepted as dimensionality. According to this, nanotubes or nanowires are considered as 2D objects, while nanofilms (e. g., graphene) are considered as 1D ones.…”

“…The schema as a whole looks rather cumbersome while it does not cover the overall class of nanomaterials and inevitably requires revision as new materials appear. For this reason, the schema of Pokropivny and Skorokhod (2008) has been used as the basis for classification in the present work. This schema Data Science Journal, Volume 11, 21 December 2012 is quite easily adaptable and is dependent only on the dimensionality of the nanostructures themselves and their components.…”

Nanostructures Properties Data System. Critical Evaluation Methodology

“…Pokropivny and Skorokhod [23] distinguish four types of objects by the dimensions as criterion, instead of separation of all nanostructures into two categories (materials and clusters). This number can have four values fro m 0 to 3.…”

“…The nu mber of classes defined with this classification is essentially limited. For examp le, when only three structural elements are used, the nu mber of classes is no more than 36 [23].…”
