an·a·tase

 (ăn′ə-tās′, -tāz′)
n.
A rare blue or light yellow to brown crystalline mineral, the rarest of three forms of titanium dioxide, TiO2, used as a pigment, especially in paint.

[French, from Greek anatasis, extension (from its long crystals), from anateinein, anata-, to extend : ana-, ana- + teinein, to stretch; see ten- in Indo-European roots.]

anatase

(ˈænəˌteɪz)
n
(Minerals) a rare blue or black mineral that consists of titanium oxide in tetragonal crystalline form and occurs in veins in igneous rocks. Formula: TiO2. Also called: octahedrite
[C19: from French, from Greek anatasis an extending (referring to the length of the crystals), from anateinein to stretch out]

an•a•tase

(ˈæn əˌteɪs, -ˌteɪz)

n.
a naturally occurring crystalline form of titanium dioxide, TiO2.
[1835–45; < French < Greek anátasis extension, derivative (with -sis -sis) of anateínein to extend (ana- ana- + teínein to stretch)]

Further, on the basis of product offerings, the concerned market for Nanoparticle Titanium Dioxide is divided into: Rutile, Anatase The market segmentation based on application include (Food Packaging Materials, Cosmetics, Others), which have constantly steered the demand for Nanoparticle Titanium Dioxide.
Titanium dioxide pigment occurs in nature and is sourced from its ores: rutile, anatase and brookite.

Based on the JCPDS (21-1272) crystallographic record it was verified the existence of only a highly crystalline anatase phase.
2, it could be illustrated for the XRD patterns of CeO2 /TiO2-Pal, their crystalline phases were identified by comparison with ICDD files (anatase TiO2, 21-1272; Palygorskite, 31-0783; cubic CeO2, 34-0394).
To a have a clearer comparison, relative anatase crystalinity was calculated by dividing the intensity of the anatase (101) diffraction peak of each sample to that of P25.
The Zr doping in Ti[O.sub.2] is chosen because Zr and Ti are isovalent, which supports adequate incorporation of Zr into the Ti[O.sub.2] lattice thereby increasing its bond length to form a solid solution of [Ti.sub.x-1][Zr.sub.x][O.sub.2] and stabilizing the anatase phase by delaying crystallite growth [8,11].
We used seven different Ti[O.sub.2] structures: Polyethylene glycol (PEG)-amorph Ti[O.sub.2], amorph Ti[O.sub.2], PEG-brookite, rutile, anatase, amorph bovine serum albumin (BSA), and brookite BSA.
The Ti[O.sub.2] produced by Evonik, known as Ti[O.sub.2]-P25 (consisting of 75% anatase phase and 25% rutile phase), is the mostly used for this purpose due to its excellent photoactivity and is also used as a reference to compare results with others news materials.
Among crystalline phases of Ti[O.sub.2], anatase and rutile are less soluble in physiological fluids than amorphous films, thus forming a more corrosion-resistant passive oxide layer [12].
In this paper, based on the density function (DFT) theory, the adsorption of benzene ([C.sub.6][H.sub.6]), styrene ([C.sub.8][H.sub.8]), and isoprene ([C.sub.5][H.sub.8]) on the anatase Ti[O.sub.2] (101) surface was carried out by simulation software of Materials Studio [18] in order to understand the adsorption mechanism of these three gases on the Ti[O.sub.2] surface, giving rise to the basic knowledge for the future application of such sensing materials upon lung cancer prognosis.
