Experiments were conducted to determine whether the presence of graphite is required to produce the Fe-Ti-P-enrichment, silica-depletion trend seen in ferrobasalts and ferrodiorites/jotunites. A nominally anhydrous Snake River Plain olivine tholeiite was crystallized at 9.3 kbar in Fe-Pt capsules; the composition of the Fe-Pt alloy was empirically chosen such that the charge neither lost nor ga...

Various morphologies of multi-walled carbon nanotubes (MWNTs) are grown catalytically on metalalloy probes in counterflow diffusion flames using methane as fuel. Carbon nanotube (CNT) properties and morphologies are investigated as functions of local gas-phase temperatures, C-related species concentrations (e.g. C2H2, CO), sampling positions, C2H2 adding to the fuel, and metal-alloy composition...

We report detailed chemical abundance analysis of 27 RGB stars towards the Galactic bulge in Baade’s Window for elements produced by massive stars: O, Na, Mg, Al, Si, Ca and Ti. All of these elements are overabundant in the bulge relative to the disk, indicating that the bulge is enhanced in Type II supernova ejecta and most likely formed more rapidly than the disk. Our [Mg/Fe] ratios, confirme...

oxidation of low density lipoprotein (ldl) has been strongly implicated in the phathogenesis of atherosclerosis. the use of oxidants in dietary food stuff may lead to the production of oxidized ldl and may increase both the development and the progression of atherosclerosis. the present work investigated the effects of some elements including: copper (cu), iron (fe), vanadium (v) and titanium (...

During its three flybys of Mercury, the MESSENGER spacecraft made the first detection of gamma-ray emission from the planet’s surface. With a closest approach distance of 200 km, the flybys provided an opportunity to measure elemental abundances of Mercury’s near-equatorial regions, which will not be visited at low altitude during MESSENGER’s orbital mission phase. Despite being limited by low ...

titanium (ti) is a relatively abundant element that has found growing applications in medical science and recently some of ti compounds are introduced as anticancer drugs. in spite of very limited data which exist on the ti metabolism, some proteins might be involved in the mechanism of action of ti. up to our knowledge, there is not any report in the literature concerning binding of ti to apol...

Investigations of phase relations in the ternary system Ti-Fe-Sb show that the single-phase region of the Heusler phase is significantly shifted from stoichiometric TiFeSb (reported previously in the literature) to the Fe-rich composition TiFe1.33Sb. This compound also exhibits Fe/Ti substitution according to Ti1+xFe1.33-xSb (-0.17 ≤ x ≤ 0.25 at 800 °C). Its stability, crystal symmetry and site...
