A nanostructure is a structure of intermediate size between microscopic and molecular structures.Nanostructural detail is microstructure at nanoscale.. In describing nanostructures, it is necessary to differentiate between the number of dimensions in the volume of an object which are on the nanoscale.
For example, clays display complex nanostructures due to anisotropy of their underlying crystal structure, and volcanic activity can give rise to opals, which are an instance of a naturally occurring photonic crystals due to their nanoscale structure.
Nanocomposite is a multiphase solid material where one of the phases has one, two or three dimensions of less than 100 nanometers (nm) or structures having nano-scale repeat distances between the different phases that make up the material.
Understanding the composite nanostructures of such materials and exploring nanomaterials' different applications may lead to the development of new materials with expanded properties, such as electrical conductivity as well as temperature-, moisture- and stress-sensing abilities. [10]
Self-assembly is defined as a process in which individual units of material associate with themselves spontaneously into a defined and organized structure or larger units with minimal external direction. Self-assembly is recognized as a highly useful technique to achieve outstanding qualities in both organic and inorganic nanostructures.
An example of a nanopolymer is silicon nanospheres which ... two-dimensional nanostructures can reinforce the polymer better than one-dimensional nanostructures, and ...
Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter.
The most common example is the production of nanocellulose from wood pulp. [39] Other examples are nanolignin, nanochitin, or nanostarches. [40] Nanoparticles with one half hydrophilic and the other half hydrophobic are termed Janus particles and are particularly effective for stabilizing emulsions.
