X-ray diffraction studies confirm the Ti02 to be rutile. It was observed in the following meteorites - Allegan, Bondoc, Estherville, Farmington, and Vaca Muerta, The rutile is associated primarily with ilmenite and chromite, in some cases as exsolution lamellae. Accepted for publication by American Mineralogist . Rutile, as a meteoritic phase, is not widely known. In their sunanary . of meteorite mineralogy neither Mason (1962) nor Ramdohr (1963) report rutile as a mineral occurring in meteorites, although Ramdohr did describe a similar phase from the Faxmington meteorite in his list of "unidentified minerals," He suggested (correctly) that his "mineral D" dght be rutile. He also ob- served it in several mesosiderites. The mineral was recently mentioned to occur in Vaca Huerta (Fleischer, et al., 1965) and in Odessa (El Goresy, 1965). We have found rutile in the meteorites Allegan, Bondoc, Estherville, Farming- ton, and Vaca Muerta; although nowhere an abundant phase, it appears to be rather widespread. Of the several meteorites in which it was observed, rutile is the most abundant in the Farmington L-group chondrite. There it occurs in fine lamellae in ilmenite. The ilmenite is only sparsely distributed within the . meteorite although wherever it does occur it is in moderately large clusters - up to 0.5 mn in diameter - and it then is usually associated with chromite as well as rutile (Buseck, et al., 1965), Optically, the rutile has a faintly bluish tinge when viewed in reflected, plane-polarized light with immersion objectives. -

Received: 4 January 2020; Accepted: 19 February 2020; Published: 23 February 2020 Abstract: Metallic and metal oxide nanoparticles (NPs), including titanium dioxide NPs, among polymeric NPs, liposomes, micelles, quantum dots, dendrimers, or fullerenes, are becoming more and more important due to their potential use in novel medical therapies. Titanium dioxide (titanium(IV) oxide, titania, TiO2) is an inorganic compound that owes its recent rise in scientific interest to photoactivity. After the illumination in aqueous media with UV light, TiO2 produces an array of reactive oxygen species (ROS). The capability to produce ROS and thus induce cell death has found application in the photodynamic therapy (PDT) for the treatment of a wide range of maladies, from psoriasis to cancer. -

Electronic Structure and Optical Properties of Prominent Phases of Tio2: First-Principles Study
Pramana – J. Phys. (2017) 89:5 © Indian Academy of Sciences DOI 10.1007/s12043-017-1400-5 Electronic structure and optical properties of prominent phases of TiO2: First-principles study SANTOSH SINGH and MADHVENDRA NATH TRIPATHI∗ Department of Pure and Applied Physics, Guru Ghasidas Vishwavidyalaya (Central University), Koni, Bilaspur 495 009, India ∗Corresponding author. E-mail: [email protected] Published online 19 June 2017 Abstract. First-principles study based on density functional theory (DFT) of two prominent phases, the rutile and the anatase phases, of titanium dioxide (TiO2) are reported within the generalized gradient approximation (GGA). Our calculated band structure shows that there is a significant presence of O-2p and Ti-3d hybridization in the valence bands. These bands are well separated from the conduction bands by a direct band gap value of 1.73 eV in the rutile phase and an indirect band gap value of 2.03 eV in the anatase phase, from to X. Our calculations reproduced the peaks in the conduction and valence band, are in good agreement with experimental observations. Our structural optimization for the rutile and anatase phase led to lattice parameter values of 4.62 Å and 2.99 Å rutile and 3.80 Å and 9.55 Å for anatase for a and c. The static dielectric values 7.0 and 5.1 for the rutile and anatase phases respectively are in excellent agreement with experimental results. Our calculation of optical properties reveals that maximum value of the transmittance in anatase phase of TiO2 may be achieved by considering the anisotropic behaviour of the optical spectra in the optical region for transparent conducting application. -

Leonardo Murialdo 1, I–00146 Roma, Italy ABSTRACT We report a new occurrence of the rare mineral wiluite, the B-rich equivalent of vesuvianite, from Ariccia, Alban Hills volcano, Rome, Italy. The specimen studied was found in the collection of the Museum of Mineralogy of the University of Rome (label MMUR22496/482). Wiluite from Ariccia was sampled at the Parco Chigi quarry, within the phreatomagmatic unit emitted by the Albano maar known locally as “Peperino di Marino”. It occurs as dark brown to black euhedral, well-formed prismatic crystals, up to 1.0 cm in length and 0.5 cm across. Optical observations show a weak pleochroism and an imperfect extinction. The mineral is uniaxial (+) with 1.722(2) and 1.727(2). It is tetragonal P4/nnc, a 15.716(2), c 11.704(2) Å, V 2890.8(7) Å3.

Abstracts of Workshop on Transport Properties of the Lower Mantle, Yunishigawa-onsen, Tochigi-ken, Japan, 2008 Scale limits on free-silica seismic scatterers in the lower mantle Craig R. Bina Dept. of Earth and Planetary Sciences, Northwestern University, U.S.A. Seismic velocity anomalies and scatterers of seismic energy in the lower mantle often are attributed to subducted oceanic lithosphere. In particular, silica-saturated basalts in oceanic crust (MORB) under lower mantle conditions should contain high-pressure phases of free silica among assemblages otherwise dominated by silicate perovskite. Free silica phases such as stishovite are expected to generate seismic velocity anomalies that are fast by a few percent relative to surrounding ultramafic peridotite or harzburgite assemblages (Mattern et al. 2002, Bina 2003a, Ricard et al. 2005), and post-stishovite phases such as CaCl2-structured silica may also generate locally slow shear-wave velocity anomalies due to displacive shear-mode transitions (Bina 2003b, Lakshtanov 2007, Konishi et al. 2008). Such models, however, must address the thermodynamic instability of free silica phases in the presence of peridotites or harzburgites, as the silica will react with adjacent ferropericlase (magnesiowüstite) to form silicate perovskite. Thus, any free silica phases preserved in the lower mantle may persist as armored relics, in which silica phases are insulated from surrounding ferropericlase phases by coronas of silicate perovskite. This parallels the situation in crustal metamorphic rocks where, for example, staurolite crystals are often found as armored relics within garnet phases or spinel crystals can be found as relics armored by staurolite poikiloblasts (Whitney 1991, Gil Ibarguchi et al. -
Relationship Among Metamorphic Grade, Vesuvianite “Rod Polytypism,” and Vesuvianite Composition
American Mineralogist, Volume 91, pages 862–870, 2006 Relationship among metamorphic grade, vesuvianite “rod polytypism,” and vesuvianite composition EDWIN GNOS1,* AND THOMAS ARMBRUSTER2 1Institut für Geologie, Universität Bern, Baltzerstrasse 1-3, CH-3012 Bern, Switzerland 2Laboratorium für chemische und mineralogische Kristallographie, Universität Bern, Freiestrasse 3, CH-3012 Bern, Switzerland ABSTRACT Single-crystal X-ray study of different vesuvianite samples of known origin shows that differ- ent metamorphic grade results in different arrangements of structural rods oriented parallel to the vesuvianite c axis, interpreted as “rod polytypism.” There is a systematic dependence of space-group symmetry and rod arrangement on crystallization temperature: P4nc-dominant < 300 °C, P4/n-domi- nant ~300–500 °C, and P4/nnc > 500 °C. Partial occupancy of the T sites (B, Al, Fe3+) and increased F-content seem to stabilize rod disorder causing P4/nnc space-group symmetry. All studied vesuvianites in calcsilicate rocks and marbles from regional- and contact-metamorphic upper amphibolite facies have disordered rods (P4/nnc symmetry). Electron-microprobe analyses of metamorphic vesuvianites from alpine and non-alpine occurrences, supported by structural investigation, showed that in addi- tion to homo- and heterovalent substitution, partial occupancy of the commonly vacant T sites by B, 3+ 4– → 4– Al, or Fe , and the (O4H4) SiO4 (hydrogarnet-type) substitutions are signiÞ cant in nature. With few exceptions, T-site occupancy seems to be restricted to high-grade metamorphic rocks whereas the “hydrovesuvianite” substitution is only found in vesuvianites formed at very low metamorphic grade. The cell parameters of vesuvianite with empty T sites increase with increasing Ti + Mg → 2 Al substitution, and this increase is even more pronounced with increasing “hydrovesuvianite” component. -
