Stepped Cu nanostripes with varying terrace widths are self-assembled during Ag-induced periodic faceting of vicinal Cu(111). By changing Ag coverage the average terrace size within individual Cu stripes is readily tuned, making it possible to select the one-dimensional or two-dimensional character of surface states. Furthermore, the average terrace size can be smoothly switched from 10 to 30 A...

Crystal growth from anhydrous hydrogen fluoride solutions of M2+ (M=Cu, Ag) and [AuF6]− gave M(AuF6)2 salts Ag). Similar attempts to prepare single crystals the corresponding nickel, zinc magnesium failed. The crystal structure Cu(AuF6)2 consists layers Cu2+ cations connected by anions, thus forming slabs. Only van der Waals interactions exist between adjacent Ag(AuF6)2 a three-dimensional fram...

The thermophilic, sulfur metabolizing Archaeoglobus fulgidus contains two genes, AF0473 and AF0152, encoding for PIB-type heavy metal transport ATPases. In this study, we describe the cloning, heterologous expression, purification, and functional characterization of one of these ATPases, CopA (NCB accession number AAB90763), encoded by AF0473. CopA is active at high temperatures (75 degrees C; ...

In this work, Ag-Cu nanoparticles (with different percentages of copper, 10%, 25%, 50%, 75% Cu) were synthesized by wet chemical method. Copper(II) sulfate and silver nitrate were taken as metal precursors, ascorbic acid as reducing agent and anhydride maleic (MA) as a modifier. The prepared nanoparticles were characterized by means of X-ray diffraction (XRD) technique and scanning electron mic...

Metal binding to fish gills forms the basis of the biotic ligand model (BLM) approach, which has emerged as a useful tool for conducting site-specific water quality assessments for metals. The current BLMs are designed to assess the toxicity of individual metals, and cannot account for the interactive effects of metal mixtures to aquatic organisms including fish. The present study was designed ...

We report on a combined scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), and density functional theory (DFT) study on the surface-assisted assembly of the hexaiodo-substituted macrocycle cyclohexa-m-phenylene (CHP) toward covalently bonded polyphenylene networks on Cu(111), Au(111), and Ag(111) surfaces. STM and XPS indicate room temperature dehalogenation of CHP on ...

To suppress Ag dewetting from around 200 <sup>o</sup>C in Ag-coated Cu (Cu@Ag) flakes, and Ni-coated (Cu@Ni@Ag) flakes were fabricated by successive Ni electroless plating. The bath type was an important consideration to induce differences the resultant oxidation. An acid contained succinic as a complexing agent sodium hypophosphite reductant, alkaline citrate hydroxide pH adjuster ...

Metal organic hybrid structures have attracted much attention due to possible applications including gas storage, heterogeneous catalysis, andmolecular separation. Hybrid structures are primarily synthesized in solution phase but can be grown under vacuum conditions. On metal surfaces, it has been reported that onedimensional (1-D) metal organic hybrid chains were grown via catalytic self-assem...

In the pursuit of electrocatalysts with great economic and ecological values for non-enzymatic glucose sensors, one-dimensional copper@carbon (Cu@C) core-shell coaxial nanowires (NWs) have been successfully prepared via a simple continuous flow wet-chemistry approach from electroplating wastewater. The as-obtained products were characterized by X-ray powder diffraction, scanning electron micros...
