A copper nanoparticle is a copper based particle 1 to 100 nm in size. [1] Like many other forms of nanoparticles, a copper nanoparticle can be prepared by natural processes or through chemical synthesis. [2] These nanoparticles are of particular interest due to their historical application as coloring agents and the biomedical as well as the ...
In materials and electric battery research, cobalt oxide nanoparticles usually refers to particles of cobalt (II,III) oxide Co. 3O. 4 of nanometer size, with various shapes and crystal structures. Cobalt oxide nanoparticles have potential applications in lithium-ion batteries [1][2] and electronic gas sensors. [3][4]
Many applications of engineered cerium oxide nanoparticles naturally disperse themselves into the environment, which increases the risk of exposure. There is ongoing exposure to new diesel emissions using fuel additives containing CeO 2 nanoparticles, and the environmental and public health impacts of this new technology are unknown. EPA's ...
Copper (II) oxide or cupric oxide is an inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu 2 O or copper (I) oxide (cuprous oxide). As a mineral, it is known as tenorite, or sometimes black copper. It is a product of copper mining and the precursor to many other copper ...
Nanomaterial-based catalysts are usually heterogeneous catalysts broken up into metal nanoparticles in order to enhance the catalytic process. Metal nanoparticles have high surface area, which can increase catalytic activity. Nanoparticle catalysts can be easily separated and recycled. [ 1 ][ 2 ][ 3 ] They are typically used under mild ...
t. e. 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. In the broadest sense this definition can include porous media, colloids, gels and copolymers, but ...
Cobalt (II,III) oxide is an inorganic compound with the formula Co 3 O 4. It is one of two well characterized cobalt oxides. It is a black antiferromagnetic solid. As a mixed valence compound, its formula is sometimes written as Co II Co III2 O 4 and sometimes as CoO•Co 2 O 3. [ 4 ]
Enzyme catalyzed reactions in biological applications are highly utilized for metabolism and processing large molecules. Nanoporous materials offer the opportunity to embed enzymes onto the porous substrate which enhances the lifetime of the reactions for long-term implants. [1] Another application is found in DNA sequencing.
