Chromium carbide (Cr3C2) is an excellent refractory ceramic material known for its hardness. Chromium carbide nanoparticles are manufactured by the process of sintering. Their notable properties include good resistance to corrosion and ability to resist oxidation even at high temperatures.
Copper oxide nanoparticles appear as a brownish-black powder. They can be reduced to metallic copper when exposed to hydrogen or carbon monoxide under high temperature.
Silicon carbide (SiC) nanoparticles exhibit characteristics like high thermal conductivity, high stability, high purity, good wear resistance and a small thermal expansion co-efficient. These particles are also resistant to oxidation at high temperatures.
Samarium oxide nanoparticles, popularly known as SM-MITE powders, are available in coated and hydrophilic forms. They can be used as solid state electrolytes for sensors, capacitors and solid oxide fuel cells.
Memristors, or memory resistors, are a kind of passive circuit element which can be used to create circuits which behave in a similar way to neurons in the brain.

Nanoparticles that occur naturally such as volcanic ash, soot from forest fires or the incidental byproducts of combustion processes are physically and chemically heterogeneous and often termed as ultrafine particles.
Nanoparticle research has come up with innovative solutions that are useful the field of cosmetics, bio medicine, and electronics; which were not possible with elements in their original states.
Silicon dioxide nanoparticles, also known as silica nanoparticles or nano-silica, are the basis for a great deal of biomedical research.
Lanthanum trifluoride nanoparticles exhibit good physical and chemical stability. Their main applications are in industrial lubricants.
Iron is highly reactive to both air (oxygen) and water, and in nanoparticles it is even more rapid than the bulk material. This characteristic limits its use to inert environments.
