The structure of nanophase ceramics is not too different than that of ceramics.The main difference is the amount of surface area per mass. Particles of ceramics have small surface areas, but when those particles are shrunk to within a few nanometers, the surface area of the same amount of a mass of a ceramic greatly increases. [3]
Nano-hydroxyapatite was proven to be better than other treatments at reducing sensitivity against evaporative stimuli, such as an air blast, and tactile stimuli, such as tapping the tooth with a dental instrument. However, no difference was seen between nano-hydroxyapatite and other treatments for cold stimuli. [30]
Ceramic nanoparticle is more than 85% air and is very light, strong, flexible and durable. The fractal nanotruss is a nanostructure architecture [3] made of alumina, or aluminum oxide. Its maximum compression is about 1 micron from a thickness of 50 nanometers. After its compression, it can revert to its original shape without any structural ...
Electroosmotic pumps are fabricated from silica nanospheres [6] [7] or hydrophilic porous glass, the pumping mechanism is generated by an external electric field applied on an electric double layer (EDL), generates high pressures (e.g., more than 340 atm (34 MPa) at 12 kV applied potentials) and high flow rates (e.g., 40 ml/min at 100 V in a pumping structure less than 1 cm 3 in volume).
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.

Therefore, analyzing the unique characteristics on NEMS and nano-scale material becomes increasingly important to retaining reliability and long-term stability of NEMS devices. [56] Some mechanical properties, such as hardness, elastic modulus, and bend tests, for nano-materials are determined by using a nano indenter on a material that has ...
Corrosion-resistant, structural tubulars and casings are important infrastructure assets in the oil and gas industry. Tubulars and casings are subject to aggressive well conditions, serving to permit operations across extreme formation and production pressure differentials, in high temperatures and in highly corrosive environments that contain hydrogen sulfide (H
