The fracture toughness of three new compositional variants of the Zr-Ti-Be-LTM (Late Transition Metal) family of bulk metallic glasses (BMG’s) are studied in the as-cast and annealed condition. Quaternary Zr-Ti-Cu-Be alloys consistently had linear elastic fracture toughness values greater than 80 MPa·m, while Vitreloy 1, a Zr-Ti-Cu-Ni-Be alloy, had an average fracture toughness of 48.5 MPa·m wi...

In this study, we demonstrated the magnetoelectric control of magnetic thin films. (111)-textured Pd/Ni/ Pd thin films were prepared on mica/lead zirconium titanate (PZT) substrates for the investigation. The reversible modulation of magnetic coercivity in Ni films was observed through the electric-voltagecontrolled strain variation from the PZT substrate. For 14 nm Ni film, the applied electri...

In the present article doping of aluminide coatings by Pt/Pd as well Hf or Pd using industrial processes was developed. The different combinations elements were tested their influence on chemical composition initially investigated. Pt and both + electroplated surface MAR M247 nickel superalloy. Zr doped during low activity CVD aluminizing process Bernex BPX Pro 325S system. conducted research s...

The coal-bearing sequences of the Late Permian in southwest China are enriched critical elements Sc, V, Co, Ni, Cu, Zn, Nb, Ta, Zr and Hf. Ascertaining conditions basis for enrichment this area is very important to support metal demands China. In study, we analyzed concentrations elemental compositions coal samples collected from Guishan coalfield eastern Yunnan, results show that C4-Upper seam...

The objective of this study was to evaluate the effects of metal ions, which may be released from orthopedic or dental implants, on osteoblast metabolism and differentiation. ROS 17/2.8 cells were cultured in F-12 medium for 7 days. Then Al+3, Co+2, Cr+3, Ni+2, Ti+4, and V+3 were added at concentrations less than their cytotoxic concentrations. After 3 days, DNA synthesis, succinate dehydrogena...

A new series of titanium(IV) and zirconium(IV) amides have been prepared from the reaction between M(NMe(2))(4) (M = Ti, Zr) and chiral ligands, (R)-2,2'-bis(p-toluenesulfonylamino)-1,1'-binaphthyl (1H(2)), (R)-2,2'-bis(diphenylphosphinoylamino)-1,1'-binaphthyl (2H(2)), (R)-2,2'-bis(mesitoylamino)-1,1'-binaphthyl (3H(2)), (R)-5,5',6,6',7,7',8,8'-octahydro-2,2'-bis(pyrrol-2-ylmethyleneamino)-1,1...
