These results suggest that inorganic nanomaterials, in general, may be better reinforcing agents compared to carbon nanotubes. Another kind of nanocomposite is the energetic nanocomposite, generally as a hybrid sol–gel with a silica base, which, when combined with metal oxides and nano-scale aluminum powder, can form superthermite materials.
Nanomanufacturing refers to manufacturing processes of objects or material with dimensions between one and one hundred nanometers. [15] These processes results in nanotechnology, extremely small devices, structures, features, and systems that have applications in organic chemistry, molecular biology, aerospace engineering, physics, and beyond.

Polymer nanocomposites (PNC) consist of a polymer or copolymer having nanoparticles or nanofillers dispersed in the polymer matrix. These may be of different shape (e.g., platelets, fibers, spheroids), but at least one dimension must be in the range of 1–50 nm. [1]
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. [45] In core-shell structure, nanomaterials form shell as the catalyst support to protect the noble metals such as palladium and rhodium. [46]
Two main approaches are used in nanotechnology. In the "bottom-up" approach, materials and devices are built from molecular components which assemble themselves chemically by principles of molecular recognition. [24] In the "top-down" approach, nano-objects are constructed from larger entities without atomic-level control. [25]
New foods are among the nanotechnology-created consumer products coming onto the market at the rate of 3 to 4 per week, according to the Project on Emerging Nanotechnologies (PEN), based on an inventory it has drawn up of 609 known or claimed nano-products. On PEN's list are three foods—a brand of canola cooking oil called Canola Active Oil ...
Nanoelectronics – use of nanotechnology on electronic components, including transistors so small that inter-atomic interactions and quantum mechanical properties need to be studied extensively. Nanomechanics – branch of nanoscience studying fundamental mechanical (elastic, thermal and kinetic) properties of physical systems at the nanometer ...
Ultrablack materials, made up of “forests” of carbon nanotubes, are important in space, where there is more light than is convenient to work with. Ultrablack material can be applied to camera and telescope systems to decrease the amount of light and allow for more detailed images to be captured. [6]
