Engineered TiO 2 nanoparticles are also used in light-emitting diodes and solar cells. [6]: 82 In addition, the photocatalytic activity of TiO 2 can be used to decompose organic compounds in wastewater. [4] TiO 2 nanoparticle products are sometimes coated with silica or alumina, or doped with another metal for specific applications. [6]: 2 [10]
Titanium dioxide, also known as titanium(IV) oxide or titania / t aɪ ˈ t eɪ n i ə /, is the inorganic compound derived from titanium with the chemical formula TiO 2.When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. [4]
Nanoparticles have different analytical requirements than conventional chemicals, for which chemical composition and concentration are sufficient metrics. Nanoparticles have other physical properties that must be measured for a complete description, such as size, shape, surface properties, crystallinity, and dispersion state. Additionally ...
Research is being carried out on the application of nanotechnology to glass, another important material in construction. Titanium dioxide (TiO 2) nanoparticles are used to coat glazing since it has sterilizing and anti-fouling properties. The particles catalyze powerful reactions that break down organic pollutants, volatile organic compounds ...
Inorganic nanoparticles have been largely adopted to biological and medical applications ranging from imaging and diagnoses to drug delivery. [22] Inorganic nanoparticles are usually composed of inert metals such as gold and titanium that form nanospheres, however, iron oxide nanoparticles have also become an option.
The metal-based nanoparticles used for biomedical prospectives are extremely enticing in various applications due to their distinctive physicochemical characteristics, allowing them to influence cellular processes at the biological level. The fact that metal-based nanoparticles have high surface-to-volume ratios makes them reactive or catalytic.
There has been recent research of TiO 2 /Au/Mg micromotors and their use and degradation efficacy against biological warfare agents, such as Bacillus anthracis, and chemical warfare agents, such as organophosphate nerve agents- a class of acetylcholinesterase inhibitors. Therefore, application of these micromotors is a possibility for medical ...
Photoactive pigments such as TiO 2 and ZnO have been used on glass, ceramic, and steel substrates for self-cleaning and antimicrobial purposes. For photocatalytic bactericidal activity in water treatment applications, granular substrate materials have been used in the form of sands supporting mixed anatase / rutile TiO 2 coatings. [ 40 ]
