Nanomaterials can also be used in three-way-catalyst applications, which have the advantage of controlling the emission of nitrogen oxides (NO x), which are precursors to acid rain and smog. [46] In core-shell structure, nanomaterials form shell as the catalyst support to protect the noble metals such as palladium and rhodium. [ 47 ]
The application potential of nanoparticles in catalysis ranges from fuel cell to catalytic converters and photocatalytic devices. Catalysis is also important for the production of chemicals. For example, nanoparticles with a distinct chemical surrounding , or specific optical properties. [citation needed]
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]
Bionics or biomimicry seeks to apply biological methods and systems found in nature to the study and design of engineering systems and modern technology. Biomineralization is one example of the systems studied. Bionanotechnology is the use of biomolecules for applications in nanotechnology, including the use of viruses and lipid assemblies.
Researchers from Rice University and State University of New York – Stony Brook have shown that the addition of low weight % of carbon nanotubes can lead to significant improvements in the mechanical properties of biodegradable polymeric nanocomposites for applications in tissue engineering including bone, [6] [7] [8] cartilage, [9] muscle [10] and nerve tissue.
Ceramic engineering – science and technology of creating objects from inorganic, non-metallic materials. Materials science – interdisciplinary field applying the properties of matter to various areas of science and engineering.
For example, multi-layer structures can be fabricated for use in electronic applications. An electrodeposited Fe/Fe oxide multi-layered sample can be an example of this application of magnetic nanocomposites. [35] In applications such as power micro-inductors where high magnetic permeability is desired at high operating frequencies. [36]
The most important feature of two dimensional nanomaterials is that their properties can be precisely controlled. This means that 2D nanomaterials can be easily modified and engineered on nanostructures. The interlayer space can also be manipulated for nonlayered materials, called 2D nanofluidic channels. 2D nanomaterials can also be engineered ...
