in order to assess the potential of copper mineralization and its associated elements in soltan meydan basaltic formation situated in the north of shahrud, the method of stream sediment and heavy mineral has been used. to achieve this aim, totally 68 samples of sediments (-80 mesh in particle size) and 6 samples of heavy minerals (-20 mesh in particle size) have been collected in an optimized n...

We report the low-temperature growth of vertically aligned carbon nanotubes (CNTs) at high growth rates by a photo-thermal chemical vapour deposition (PTCVD) technique using a Ti/Fe bilayer film as the catalyst. The bulk growth temperature of the substrate is as low as 370 °C and the growth rate is up to 1.3 µm min(-1), at least eight times faster than the values reported by traditional thermal...

Oxide Dispersion Strengthened (ODS) steels are candidate materials for both fission and fusion nuclear reactors. In this study, the microstructure of ferritic (Fe-14Cr-1W) / martensitic (Fe-9Cr-1W) ODS has been characterized after two different processing routes: Hot Extrusion (HE) Isostatic Pressing (HIP). Transmission Kikuchi Diffraction (TKD) revealed presence Ti-rich precipitates on every s...

Bioavailability of engineered metal nanoparticles affects uptake in plants, impacts on ecosystems, and phytoremediation. We studied uptake and translocation of Ti in plants when the main source of this metal was TiO2 nanoparticles. Two crops (Phaseolus vulgaris (bean) and Triticum aestivum (wheat)), a wetland species (Rumex crispus, curly dock), and the floating aquatic plant (Elodea canadensis...

The paper demonstrates the potential of wet ball milling metals for synthesis various carbides and carbohydrides. work reports on multicomponent formed in Ti-(Cu/Fe/Si)-C, W-Fe-C, Nb-(Cu/Fe/Si/Al)-C systems, as well metastable or high-temperature intermetallics Ti-Si, Nb-Si, Nb-Al, Nb-Cu-Fe which are stabilized with interstitial carbon. formation phase composition powders fabricated under mecha...

2014 Crystallographic and kinetic characteristics of martensitic transformations and parameters of shape memory effect in B2 compounds of titanium Ti50Ni50-xXx (X = Fe, Co, Pd, Pt, Au, Cu) and Ti50Pd50-xYx (Y = Fe, Co, Cu), where 0 ~ x ~ 50 are investigated. Temperature, hysteresis, value of reversible deformation and stress of martensitic shear for martensitic transformations and shape memory ...
