Abrasive wear behaviour of WC-Co and Fe/Cu-based nanostructured coatings has been investigated under dry slurry conditions in this study. The retention coating constituents was confirmed together with the formation various metallic ceramic phases. rate one order lower than that micro-structured both conditions. Relatively higher abrasion resistance such compare to reference material because com...

In view of uncontrolled observations and anecdotal reports suggesting that the activated PCC, Autoplex, was much more effective than standard (non-activated) PCC in controlling bleeding in hemophiliacs with inhibitors, a controlled double-blind study was designed to compare the effectiveness of Autoplex and Proplex. Acute hemarthrosis was chosen for study as this common but non-life-threatening...

Abstract To investigate the effect of impregnation sequence on SCR-C 3 H 6 performance, Al-PILC based catalysts with different sequences between Cu and Fe were prepared. Activity result showed that influenced where, NO conversion followed order from high to low: Cu-Fe/Al-PILC>FeCu/Al-PILC>CuFe/Al-PILC. XRD results indicated dispersion active phase was related sequence. The specific surfac...

Phosphate poisoning of Pt electrocatalysts is one the major barriers that constrains performance phosphoric acid-doped polybenzimidazole (PA/PBI) membrane fuel cells. Herein, we developed new atomically dispersed bimetallic FeCu coordinated with nitrogen-doped carbon nanotubes (FeCu/N-CNTs) as Pt-free oxygen reduction reaction (ORR) electrocatalysts. The cell FeCu/N-CNTs cathodes delivers a pea...

We have calculated the electronic structure of the tetragonal L10 ordered FeCu by solving self-consistently a tight-binding Hamiltonian for s, p and d electrons. We have found by total energy calculation that this structure is ferromagnetic. In addition, we have determined that the equilibrium ratio between the interlayer and the intralayer lattice parameters is 0.947. PACS numbers: 75.50.Rr, 7...

In this paper, the effect of magnetic field on the morphology, structure and magnetic properties of electrodeposited FeCu/Cu thin films was investigated. The films were deposited on Au2PdAg/glass substrates using electrodeposition technique in potentiostatic control. The magnetic fields of 5000 and 7000 Oe were applied on deposition bath during deposition. Two series of thin films were prepared...
