Abstract In the FFC-Cambridge process, cathodic dissociation of oxide and CO/CO 2 production on carbon anode is basis for metal in a CaCl bath. Using an inert intermetallic anode, CO evolution can be eliminated altogether with acceleration electro-reduction kinetics. presence TiO suffers from slow reduction kinetics to Ti metal, which enhanced significantly by incorporation alkali species pelle...

The incorporation of Bi in GaSb1 xBix alloys grown by molecular beam epitaxy is investigated as a function of Bi flux at fixed growth temperature (275 1C) and growth rate ð1 μm h Þ. The Bi content is found to vary proportionally with Bi flux with Bi contents, as measured by Rutherford backscattering, in the range 0oxr4:5%. The GaSbBi samples grown at the lowest Bi fluxes have smooth surfaces fr...

The standard heterogeneous rate constants for the reduction of a series of viologen derivatives with a range of inter-ring torsion angles were measured at Bi and Pt electrodes. The electrode potentials for the first one-electron reduction of the viologens vary from -684 mV to -1070 mV vs. Ag/0.01 m Ag+; this enabled a comparison of the behaviour of metallic (Pt) and semi-metallic (Bi) electrode...

A new analytical approach to optimize the thicknesses of a two-layer absorbing structure constituted by graphene-based composite and polymer dielectric spacer backed metallic layer acting as perfect electric conductor (PEC) is proposed. The lossy sheet made an epoxy-based vinyl ester resin filled with graphene nanoplatelets (GNPs) characterized known frequency spectra complex permittivity. opti...

Inhibiting amyloid-β (Aβ) fibril formation is the primary therapeutic strategy for Alzheimer's disease. Several small molecules and nanomaterials have been used to inhibit Aβ fibril formation. However, insufficient inhibition efficiency or poor metabolization limits their further applications. Here, we used hemin to exfoliate few-layer Bi(2)Se(3) in aqueous solution. Then we separated few-layer...

However, problems such as osteoporosis due to high elasticity of metals relative to bones, and local infections and systemic problems caused by releasing metallic ions have motivated research on replacing metallic screws with non metallic ones. In this study, the composite containing poly-l-lactic acid and bioactive glass fibers were considered for the design of the screw using ABAQUS software ...

in this paper, a novel method of producing bi-metallic alloy nanoparticles at low temperatures using hydrogen bombardment of thin films, deposited on glass substrates, is introduced. optical and morphological characteristics of the nanoparticles were extensively studied for various conditions of plasma treatment, such as plasma power density, temperature, duration of hydrogen bombardment, thick...

We analyze the phase diagram of single and bi-layer cuprates using the gaugefield description of the t-J model. For T > TBE the in-plane fermion-pairing order parameter ∆‖ is eliminated by gauge field fluctuations, leading us to predict the absence of a spin-gap phase in single-layer cuprates. For bi-layer cuprates the inter-layer order parameter ∆⊥ is enhanced by spin correlations, and is less...

   In This paper, the effect of size on melting temperature of metallic nanoparticles (Au, Pb and Bi) is theoretically simulated and explained. In this regard, the cause of difference in various experimental data is introduced, which is the difference between nanoparticles’ grain Gaussian distribution. This volume-depended model with the help of the Gaussian distribution can descri...
