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 [...]

Effect of Reactive Ball Milling Time on the Hydrogenation/Dehydrogenation Properties of Nanocomposite MgH2/7TiMn1.5 Powders

Sherif El-Eskandarany M., Al-Matrouk H., Shaban E., Al-Duweesh A., Kuwait Institute for Scientific Research, State of Kuwait, KW

Reactive ball milling (RBM) technique was employed to synthesize ultrafine powders of -MgH2 phase coexisted with small mole fractions of -MgH2 phase. The metal hydride powders were prepared at room temperature under 50 bar of [...]

Study of synergistic interactions between SiO2 nanoparticles and CTAB in the presence of NaCl: relationships with the formation and stabilization of hexadecane-in-water emulsions

Fouconnier B., Román-Guerrero A., Vernon-Carter J., Universidad Veracruzana, MX

The synergistic interactions between silica (SiO2) nanoparticles and a surfactant cetyltrimethylammonium bromide (CTAB) on the shear viscoelastic properties of the hexadecane-water (H/W) interfacial films as well as the formation and stability of emulsions were investigated. [...]

Characterizing Environmental Transformation of Multi-walled Carbon Nanotubes and Carbon Nano-Fiber Composites using Thermal Analysis and Related Hyphenated Techniques

Sahle-Demessie E., Zhao A., Salamon A.W., Cassel B., Gagliardi N.A., U.S. Environmental Protection Agency, US
