what is a 3D nanomaterial

0 confine dimensions but size within nano range eg 100nm NP

Define a positive nanostructure

NP in air/liquid or polymer matrix

Define a negative nanostructure

nanoscale void in a solid matrix

How does the connectivity of nanostructures affect them

S/V ratio, rigidity, templates, usability as membranes/filters, usability for catalysis

Define top down fabrication

material removal, can require precise instruments, res often given by beam diameter or scattering

Define bottom up fabrication

material deposition in small areas/structures

Define remote organisation

nanoobjects moved using assembler device controlled by computer/electronics, slow serial process

Define self organisation

building blocks arrange themselves into regular pattern minimising energy; can be externally supported by polar/nonpolar agent molecules; parallel and faster process

Soft nanomaterials

organic (polymer), hollow, large molecular assemblies, biomimetics

Hard nanomaterials

Inorganic SC particles, metallic and magnetics, oxide + ceramics

How can nanomaterials be classified

size, dimensionality, positive/negative structure, connectivity, ordering, fabrication, assembly method, organic/inorganic, hard/soft, natural/artificial
