• The dual site consisting of Al or Zr the support and Cu species is active. DFT indicates synergy acid sites supports species. Copper dispersion a sensitivity descriptor for activity. Glycerol produced in large quantities as byproduct biodiesel, among others hydroxyacetone (acetol) an important commodity obtained from glycerol. Metallic has been identified active dehydration glycerol to metal ...

Alloy design coupled with metal additive manufacturing (AM) opens many opportunities for materials innovation. Investigating the effect of printing parameters alloy is essential to achieve good part quality. Among different factors, laser absorptivity, heat diffusivity, and in situ intermetallic phase formations are critical. In this study, first step employed was a reduction Al V contents Ti6A...

Al-based alloys are often selected for use in various engineering applications as well the aircraft and aerospace industry. The improvement of their performances under severe conditions have required alloying elements. In present work, Be is added to eutectic Al-33 wt.%Cu alloy with a view investigating resulting effects on microstructural features hardness. A directional solidification techniq...

Nano-sized, nonreacting, noncoarsening ZrO2 particles reinforced Sn–3.0 wt%Ag–0.5 wt%Cu composite solders were prepared by mechanically dispersing ZrO2 nano-particles into Sn–Ag–Cu solder. The interfacial morphology of unreinforced Sn–Ag–Cu solder and solder joints containing ZrO2 nano-particles with Au/Ni metallized Cu pads on ball grid array (BGA) substrates and the distribution of reinforcin...

The mechanical properties of Al-Si-Mg-Cu cast alloys are heavily determined by Cu content due to the precipitation relating strengthening precipitates during aging treatment. In this study, microstructures and Al-9Si-0.5Mg-xCu (x = 0, 0.9, 1.5, 2.1 wt.%) were investigated elucidate effect on evolution their properties. After T6 (480 °C + 6 h − 530 4 h, 175 10 h) treatment, Mg-rich Cu-rich phase...

Bacteria can survive on hospital textiles and surfaces, from which they can be disseminated, representing a source of health care-associated infections (HCAIs). Surfaces containing copper (Cu), which is known for its bactericidal properties, could be an efficient way to lower the burden of potential pathogens. The antimicrobial activity of Cu-sputtered polyester surfaces, obtained by direct-cur...
