  2. Titanium dioxide nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Titanium_dioxide_nanoparticle

    Doping TiO 2 with certain atoms its photocatalytic activity could be enhanced. [8] In contrast, pigment-grade TiO 2 usually has a median particle size in the 200–300 nm range. [6]: 1–2 Because TiO 2 powders contain a range of sizes, they may have a fraction of nanoscale particles even if the average particle size is larger. [9]

  3. Titanium dioxide - Wikipedia

    en.wikipedia.org/wiki/Titanium_dioxide

    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]

  4. Protein nanoparticles - Wikipedia

    en.wikipedia.org/wiki/Protein_nanoparticles

    Protein nanotechnology is a field of research that integrates the diverse physicochemical properties of proteins with nanoscale technology. This field assimilated into pharmaceutical research to give rise to a new classification of nanoparticles termed protein (or protein-based) nanoparticles (PNPs).

  5. Brookite - Wikipedia

    en.wikipedia.org/wiki/Brookite

    Brookite is the orthorhombic variant of titanium dioxide (TiO 2), which occurs in four known natural polymorphic forms (minerals with the same composition but different structure). The other three of these forms are akaogiite ( monoclinic ), anatase ( tetragonal ) and rutile ( tetragonal ).

  6. Rutile - Wikipedia

    en.wikipedia.org/wiki/Rutile

    Rutile is an oxide mineral composed of titanium dioxide (TiO 2), the most common natural form of TiO 2. Rarer polymorphs of TiO 2 are known, including anatase, akaogiite, and brookite. Rutile has one of the highest refractive indices at visible wavelengths of any known crystal and also exhibits a particularly large birefringence and high ...

  7. Silanization - Wikipedia

    en.wikipedia.org/wiki/Silanization

    The nature of the organic group on the silanization agent strongly influences the properties of the surface. Simple alkyl-containing silanizing groups confer hydrophobicity. When side chains of the silane compound are amines or thiols, the surfaces assume the properties of those functional groups. [5]

  8. Self-assembled monolayer - Wikipedia

    The final structure of the SAM is also dependent on the chain length and the structure of both the adsorbate and the substrate. Steric hindrance and metal substrate properties, for example, can affect the packing density of the film, [1] [10] while chain length affects SAM thickness. [12] Longer chain length also increases the thermodynamic ...

    Also known is Ti 2 O 3, with the corundum structure, and TiO, with the rock salt structure, although often nonstoichiometric. [10] The alkoxides of titanium(IV), prepared by treating TiCl 4 with alcohols, are colorless compounds that convert to the dioxide on reaction with water. They are industrially useful for depositing solid TiO 2 via the ...
