The adsorption properties of Shewanella xiamenensis immobilized on zeolite have been evaluated in order to determine its applicability for remediation silver-containing effluents with different chemical composition. effects pH (2.0–6.0), contact time (15–150 min), silver concentration (10–100 mg/L) and temperature (20–50 °C) the bio-zeolite efficiency were investigated batch experiments. optima...

The changes in microstructure and microhardness of Sn-0.5%Ag, Sn-1.0%Ag, and Sn-0.7%Cu Pb-free solders were investigated during high temperature aging at 200°C for 2 h. As-solidified microstructures, revealed by cross-polarized light microscopy, consist of relatively large grains of β-Sn phase with twinned microstructure in both Sn-Ag and Sn-Cu solders. The bright-field light microscopy display...

Phase equilibria in the ternary Ti-Ag-Cu system have been studied thermodynamically and experimentally at various temperatures. The thermodynamic analysis was performed by combining the most recent data on the binary Ag-Cu, Ti-Ag and Ti-Cu systems and experimental information obtained by the diffusion couple technique. The eutectic and three noneutectic binary Ag-Cu alloys were melted and annea...

Incorporation of metallic particulate reinforcements in eutectic Sn-Ag solder re­ sults in the formation of intermetallic compounds (IMCs) along particulate/ solder interfaces with different morphologies. For instance, “sunflower” and “blocky faceted” IMC shapes have been observed around Ni particle reinforce­ ments incorporated in the eutectic Sn-Ag solder matrix. The time and tempera­ ture ab...

Ag-Cu-Ti system is important for brazing applications and mainly for ceramic joining. This system is characterized by numerous intermetallics in the Cu-Ti binary and the existence of a miscibility gap in the liquid phase. For applications, the knowledge of phase equilibria, invariant reactions in the temperature range of interest and thermodynamic activity values (mainly of Ti) are important. T...

A new embedded-atom method (EAM) potential has been constructed for Ag by fitting to experimental and first-principles data. The potential accurately reproduces the lattice parameter, cohesive energy, elastic constants, phonon frequencies, thermal expansion, lattice-defect energies, as well as energies of alternate structures of Ag. Combining this potential with an existing EAM potential for Cu...

Annealing of dilute binary Cu(Ti), Cu(In), Cu(Al), Cu(Sn), Cu(Mg), Cu(Nb), Cu(B), Cu(Co) and Cu(Ag) alloy films resulted in the strongest <111> fiber texture for Cu(Ti) and the lowest resistivity for Cu(Ag). The behavior of the alloy films was compared and contrasted with that for a pure evaporated Cu film. Electron beam evaporated films with compositions in the range of 2.0-4.2 at% and thickne...

ulations must be considered. We totally agree with his arguments. His constructive, detailed technical explanations should be tested thoroughly by the manufacturers of Ag/Cu ionization systems and taken into consideration in future experiments. Dr. Lin’s main scientific point is that the data we presented in our paper do not support the claim that Legionella developed resistance to silver. He a...

Effects of duration of exposure of single metal cations (Ag+1, Cd+2, Cu+2, Ga+3, Ni+2, and Zn+2) on 3H-thymidine (3H-Tdr) incorporation and 3-[4,5-dimethyl-thiazol-2yl-]-2,5-diphenyl tetrazolium bromide-formazan (MTT-f) production in cultured murine fibroblasts (Balb/c 3T3) were investigated, and the synergistic and antagonistic effects of two metal cations applied simultaneously to the fibrobl...
