Precipitation-Strengthened and Microlayered Bulk Copper- and Molybdenum-Based Nanocrystalline Materials Produced by High-Speed Electron-Beam Evaporation–Condensation in Vacuum: Structure and Phase Composition

Grechanyuk N.I., Grechanyuk V.G., Grechanyuk N.I., Grechanyuk V.G., Manulyk A.F., Synergy ANTECH Services Corp., CA

The phase composition and structurization of three types of copper and molybdenum composite materials, 0.8 to 5 mm thick, were condensed from the vapor phase at substrate temperatures 700 and 900 0C. They are considered: [...]

Engineered Core-Shell Cu particles demonstrate strong potential for plant disease control

Young M., Ozcan A., Myers M.E., Graham J.H., Santra S., University of Central Florida, US

Copper (Cu) bactericides/fungicides are used extensively for crop protection in agriculture. There is an increasing concern for Cu accumulation in fertile soil and potential for Cu leaching into the surrounding ecosystem. Moreover, development of Cu [...]

Intense Pulsed Light Sintering and Reduction of Facile Copper Hydroxide Synthesis towards Printable Copper Contacts

Druffel T., Dharmadasa R., Draper G., University of Louisville, US

The printed electronics market is a rapidly growing field, with the market set to reach $3.6B by 2018. Conductive inks are used in a vast variety of technologies. Inks are typically composed of metallic particles [...]

The Safe & Efficient Electrical Transmission for Energy Markets and Grid Technology

Strong Z., Copper Development Association, US

The future U.S. market for grid energy storage continues to grow making the associated copper demand for storage applications robust, according to a study commissioned by the Copper Development Association (CDA). There is a tremendous [...]

Ionic liquid: an innovative medium for nanofabrication

Darwich W., Santini C.C., Gaillard F., Haumesser P.-H., université de lyon 1, CNRS UMR 5265, FR

Porous silicon (PSi) has been attracting a great attention as a breakthrough material with exceptional characteristics for microelectronics, layer transfer technology, solar and fuel cells, biomedicine, etc. Its properties can be modified by in introducing [...]

Temperature Stability of AgCu Nanoparticles

Sopousek J., Zobac O., Vykoukal V., Bursik J., Roupcova P., Broz P., Pinkas J., Vrestal J., Masaryk University, CZ

The Ag-Cu nanoparticles (NPs) were prepared from metallo-organic precursors by solvothermal synthesis. The CALPHAD approach was used for prediction of the Ag-Cu phase diagram in both macro and nano scales. The detailed experimental characterization was [...]

Photoluminescence Studies of Green Synthesized Copper Nanoparticles

Annapurna S., Suresh Y., Sreedhar B., Singh A.K., Bhikshamaiah G., Osmania University College for Women, IN

Copper nanoparticles are prepared using a two stage chemical reduction method. Potato starch and Ocimum Sanctum leaf extract are used to stabilize the copper nanoparticles. This approach is proved to be an efficient method for [...]

Synthesis and Characterization of Copper-Copper oxide nanofluids in the confinement regime

Babukutty B., Parakkal F., Bhalero G.M., Nair S.S., Central University of kerala, IN

Abstract: Copper oxide shelled copper nanofluids are synthesized with surfactant trioctylphosphine oxide (TOPO) using sulphates precursors. The fluids were structurally characterised by X-ray Diffraction (XRD). Surface and morphological characterization are carried out by Scanning Electron [...]

Microwave-assisted hydrothermal synthesis of Cu-doped titanate nanotubes: photoluminescence and photocatalysis properties

Manfroi D.C., Andrade L.P., Cavalheiro A.A., Jos A.A., Teixeira G.F., Perazolli L.A., Varela J.A., Zaghete M.A., Universidade Estadual Paulista, BR

Alkali titanates have been intensively investigated mostly because of their properties. And the interest for transition metal doping of 1D titanate nanostructures is enormous, especially copper. In the present work we report the synthesis of [...]
