The metal binding properties of the human copper chaperone ATOXI and its yeast homologue Atxl have been characterized. Complexes of these proteins with Cu(I), Ag (1), Cd(II) and Hg(II) were studied by native gel electrophoresis, chemical cross-linking followed by SDS-PAGE, as well as by size exclusion chromatography, mutagenesis and UV-visible absorption spectroscopy. Results indicate that bind...

The supersaturated solid-solution interfaces between Cu core and Ag shell structures improve their bonding strength greatly prevent the outward diffusion of atoms slow down growth oxides. printed CuAg x electrodes maintain high conductivity for a long time even at 220 °C, which is far better than conventional core/Ag Cu/Ag mixed that rapidly oxidize below 150 °C. These findings not only promote...

Abstract To improve the tribological performance of CSS-42L bearing steel, smooth surfaces (SSs), groove-textured (GSs), GSs with Sn-Ag-Cu (GSs-SAC), and Sn-Ag-Cu-Ti 3 C 2 (GSs-SACT) were prepared on CSS-42L. In addition, experimental studies conducted properties. The obtained results indicated that GSs-SACT exhibited best anti-friction noise reduction performances. These remarkable performance...

Abstract A three-dimensional (3D) band-gap energy ( E g ) map was constructed for a (Cu 1− y Ag )(Ga x In )Se 2 (CAGISe) system. This system’s increases monotonically from CuInSe (CISe) as the ratios of both Ga/(Ga+In) [GGI], , and Ag/(Cu+Ag) [ACA], increase. Furthermore, levels VB maximum (VBM) conduction band minimum (CBM) were also mapped in 3D. this CAGISe system, there is no significant ch...

Fluorescent DNA-Ag NCs are demonstrated as novel, label-free, and turn-on fluorescence probes for Cu(2+) ions sensors. We also used this novel fluorescent probe to determine Cu(2+) ions in Montana soil (SRM 2710) and pond water.

Eutectic structures in Ag-based brazing filler metals play an important role improving the properties of alloys and brazed joints. The typical microstructures morphological evolution Ag-Cu eutectic solidified at various cooling rates with addition different Sn contents were investigated. formation mechanisms anomalous structure (AES) transition from lamellar (LES) to AES elucidated. a slow rate...

In our recently published paper, [ 1 ] we achieved direct visualization of the dynamic growth and dissolution of conductive fi laments (CFs) in Ag (or Cu)/ZrO 2 /Pt systems based on in situ transmission electron microscope (TEM) observations. Furthermore, continuous TEM images clearly showed that the CFs start to grow at the Cu/ZrO 2 (or Ag/ZrO 2 ) interface and begin to dissolve at the ZrO 2 /...

Whilst Cu(In,Ga)Se2 (CIGSe) is an extremely promising material for solar cell fabrication, the widening of band gap beyond standard 1.1 eV highly desirable semitransparent applications. By replacing Cu with Ag and increasing Ga content, we fabricate ACIGSe absorbers gaps ranging from 1.27–1.55 eV. An Ag/(Ag + Cu) ratio 0.36–1.00 chosen, as well a Ga/(Ga In) 0.25–0.59. The larger contents lead t...
