The mixed-valent titanium phosphate, Li(2)Ti(2)(PO(4))(3), has been prepared by the reactive halide flux method. The title compound is isostructural with Li(2)TiM(PO(4))(3) (M = Fe, Cr) and Li(2)FeZr(PO(4))(3) and has the same (3) (∞)[Ti(2)(PO(4))(3)](2-) framework as the previously reported Li(3-) (x)M(2)(PO(4))(3) phases. The framework is built up from corner-sharing TiO(6) octa-hedra and PO(...

The interface relationship between (Ti, Nb)(C, N) carbonitride and CeO2 was calculated by first-principles method. mechanism that as the nucleus of in Fe-Cr-C-Ti-Nb-N coating analyzed. microstructure hypereutectic Fe-Cr-C-Ti-Nb-N-CeO2 observed this paper. results show that, calculating phonon dispersion curves binding energy, most stable structure is Ti3NbCN3. two-dimensional lattice misfit Ti3...

thermoluminescent detector/LiF:Mg,Ti/glow curve deconvolution/annealing/NIRS-HIMAC The stability of glow peaks in LiF:Mg,Ti (TLD-600) exposed to a high-energy Fe-ion beam was examined in comparison to Cs γ -ray irradiation under changing annealing conditions. The peak areas induced by the Fe ions were much smaller than those by γ -rays. The sizes and positions of peaks 3–5 in Fe-ion irradiated ...

Tire dust is a significant pollutant, especially as a source of zinc in the urban environment. This study characterizes the morphology and chemical composition of heavy metal particles embedded in tire dust and traffic-related materials (brake dust, yellow paint, and tire tread) as measured by a field emission scanning electron microscope equipped with an energy dispersive X-ray spectrometer (F...

Jet-induced supernovae (SNe) have been suggested to occur in gamma-ray bursts (GRBs) and highly-energetic SNe (hypernovae). I investigate hydrodynamical and nucleosynthetic properties of the jet-induced explosion of a population III 40M⊙ star with a two-dimensional special relativistic hydrodynamical code. The abundance distribution after the explosion and the angular dependence of the yield ar...

The creep strength of ferritic steels can be substantially improved by the incorporation of a high number density of nano-scale dispersoids. Examples for such alloys are the oxide dispersion strengthened steels MA956, MA957, and PM2000. The dispersoids in these steels contain Y and Ti, or Y and Al. They can be as small as a few nanometers in size. Processing is traditionally carried out by mech...

Metal-metal charge transfer (MMCT) is expected to be the main mechanism that enables the harvesting of solar light by iron-titanium oxides for photocatalysis. We have studied FeTiO3 as a model compound for MMCT with 1s2pRIXS at the Fe K-edge. The high-energy resolution XANES enables distinguishing five pre-edge features. The three first well distinct RIXS features are assigned to electric quadr...

We study nucleosynthesis in ’hypernovae’, i.e., supernovae with very large explosion energies ( ∼ > 10 ergs) for both spherical and aspherical explosions. The hypernova yields compared to those of ordinary corecollapse supernovae show the following characteristics: 1) Complete Siburning takes place in more extended region, so that the mass ratio between the complete and incomplete Si burning re...

We report the first detailed chemical abundances for 5 globular clusters (GCs) in M31 from highresolution (R ∼ 25,000) spectroscopy of their integrated light. These GCs are the first in a larger set of clusters observed as part of an ongoing project to study the formation history of M31 and its globular cluster population. The data presented here were obtained with the HIRES echelle spectrograp...

The residual-stress induced failure of Ti-6Al-4V/Si3N4 joints brazed with two different Si3N4 ceramics possessing intrinsic properties was elucidated through experimental and finite-element (FE) thermo-mechanical simulations incorporating the local elasto-plastic as-received Ag-Cu-Ti filler brazing zone characterized by nano-indentation. All tested fractured mainly from due to residual stress, ...
