Introduction: The A16 (Apollo16) site in the lunar nearside highlands is 220 km from the nearest mare. Thus it is no surprise that mare basalt samples are uncommon at the site. Here, we present the petrography and geochemistry of 5 new mare basalt samples found at the A16 site. We also discuss possible provenances of all A16 mare basalt samples using high-resolution global data for the distribu...

In this paper, a nanocrystalline surface layer without impurities was fabricated on Ti-6Al-4V alloy by means of surface mechanical attrition treatment (SMAT). The grain size in the nanocrystalline layer is about 10 nm and grain morphology displays a random crystallographic orientation distribution. Subsequently, the low-temperature boriding behaviors (at 600 °C) of the SMAT sample, including th...

Bulk nanocrystalline Ti bars (Grade 4, Φ4 × 3000 mm(3)) were massively fabricated by equal channel angular pressing (ECAP) via follow-up conform scheme with the microcrystalline CP Ti as raw material. Homogeneous nanostructured crystals with the average grain size of 250 nm were identified for the ECAPed Ti, with extremely high tensile/fatigue strength (around 1240/620 MPa) and adorable elongat...

The main results obtained by using IR, Raman and W-Vis techniques concerning the structure of the Ti(IV) center in Ti-silicalite is briefly reviewed and discussed with recent XAFS results. The Ti(1V) is in tetrahedral coordination in vacuo and expands its coordination sphere upon interaction with adsorbates. Present EXAFS results indicate, for the dehydrated sample, a fust shell coordination nu...

Hydroxyurea (HU) has been successfully used in patients with β-thalassemia intermedia (β-TI). We aimed to evaluate the effect of the long-term use of HU on thyroid function in patients with β-TI. Seventy-five patients with β-TI aged≥11 years and taking HU were randomly selected during 2010 in southern Iran. Thirty-one patients with β-TI without HU were considered as a control group. Serum level...

Grafting of Co(NCCH3)2Cl2 onto mesoporous Ti-MCM-41 silica in acetonitrile solution affords binuclear Ti-O-Co sites on the pore surface under complete replacement of the precursor ligands by interactions with anchored Ti centers and the silica surface. The Co ligand field spectrum signals that the Co centers are anchored on the pore surface in tetrahedral coordination. FT-infrared action spectr...

background: nickel-titanium (ni-ti) rotary instrument files are important devices in endodontics in root canal preparation. ni-ti file breakage is a critical and problematic issue and irrigation techniques were applied to decrease risk of file failure root. the aim of the present study was to compare the temperature gradient change of different irrigation solutions with ni-ti rotary instrument ...

Introduction: Different neutron rich isotopes (Ti, Cr, Ni and Zr) display well documented isotopic heterogeneities between various meteorite groups and the Earth-Moon system [16]. The origin of these variations is not well understood. It has been suggested that the observed Ti isotope pattern in bulk solar system materials was generated by thermal events during solar system formation [2]. An al...

All trademarks are the property of their respective owners. TI Designs This TI Design provides an analog front-end (AFE) solution for measuring PM2.5 and PM10 particulate matter (PM). The design detects the light scattered by particles suspended in air. A sample software algorithm is provided to convert the analog output of the design into a particle size and concentration measurement. Test res...

Introduction: A system of solar composition is so reducing that Ti and Ti can coexist, making the valence of Ti a valuable indicator of fO2 conditions during formation of nebular materials. The Ti/Ti ratios observed in the Ti-rich phases fassaite and rhönite in coarse-grained refractory inclusions from CV3 chondrites have been shown [1,2] to be quantitatively consistent with formation in a gas ...
