What are incidental nanomaterials?
Incidental nanomaterials—A nanomaterial unintentionally produced as a result of any form of direct or indirect human influence or anthropogenic process. Engineered nanomaterials—A nanomaterial conceived, designed, and intentionally produced by humans.
What is the difference between nanostructures and nanomaterials?
Nanomaterial: Material with any internal or external structures on the nanoscale dimension. Nanostructure: Composition of interconnected constituent parts in the nanoscale region. Nanostructured materials: Materials containing internal or surface nanostructure.
What are nanostructures used for?
Abstract. Metal nanostructures are used to enhance optical responses by means of surface-enhanced spectroscopies such as Raman scattering, infrared absorption, and fluorescence spectroscopies.
What is the classification of nanomaterials?
Nanomaterials can be categorized into four types [9, 10] such as: (1) inorganic-based nanomaterials; (2) carbon-based nanomaterials; (3) organic-based nanomaterials; and (4) composite-based nanomaterials. Generally, inorganic-based nanomaterials include different metal and metal oxide nanomaterials.
What are the two naturally occurring nanomaterials in the Philippines?
Nanotechnology is an emerging technology that uses the structure and composition of materials in the order of nanometer (a billionth of a meter). The Philippines has the potential in the area of nanotechnology due to the abundance of naturally-occurring nanomaterials such as clay, limestone, silica, and zeolite.
What are engineered nanomaterials examples?
Examples of engineered nanomaterials include carbon buckeyballs or fullerenes, carbon nanotubes, metal or metal oxide nanoparticles (e.g. gold or titanium dioxide), and quantum dots, among many others.
Can you give other examples of nanostructures?
Nanostructures — objects with nanometer scale features – are not new nor were they first created by man. Nature has many examples of nanostructures such as hydrophobic leaves, iridescent butterfly wings, and the gecko’s foot.
What are Nanoengineered materials?
Generally, nanoengineered materials can be categorized as carbon (organic) and noncarbon (inorganic) materials. Among carbon based materials are carbon nanotube and graphene, while noncarbon materials include metal and metals oxides.
