A series of composite films containing poly(vinylidene fluoride) (PVDF), carbon nanotubes, graphene and bimetallic nanorods, in which copper was wrapped with nickel (Cu@Ni), were fabricated via solution casting compression molding.

Copper nanoparticles (CuNPs) embedded in polyvinylpyrrolidone (PVP) and polyethylene oxide (PEO) fiber-matrices were prepared through centrifugal spinning of PVP/ethanol PEO/aqueous solutions, respectively. The prime focus the current study is to investigate antibacterial activity composite fibers against Escherichia coli (E. coli) Bacillus cereus (B. cereus) bacteria. During fiber formation, p...

Abstract: materials can be fabricated by sintering of W-Cu composite powders. In this research W-20%wt Cu composite powderswas synthesized via a co-precipitation method. Precipitate obtained from a mixture of copper nitrate and ammoniumparatungstate (APT) in distilled water contained W-Cu compounds. This precipitate was washed, dried and calcinedat 550 of dried precipitate powder was determined...

In this work the individual and combined effect of four process parameters, i.e. initial copper (II) concentration, adsorbent dose, initial solution pH, and contact time on the adsorption of copper (II) from aqueous solution were studied by neem bark powder (NBP) using response surface methodology (RSM) approach based on central composite design (CCD). Copper (II) removal is maximum at the pH: ...

Hollow silica-copper-carbon (H-SCC) nanocomposites are first synthesized using copper metal-organic frameworks as skeletons to form Cu-MOF@SiO(2) and then subjected to heat treatment. In the composites, the hollow structure and the void space from the collapse of the MOF skeleton can accommodate the huge volume change, buffer the mechanical stress caused by lithium ion insertion/extraction and ...

21 The Menkes protein (ATP7A) is defective in the Cu deficiency disorder, Menkes 22 disease and is an important contributor to maintenance of physiological copper homeostasis. To 23 investigate more fully the role of ATP7A, transgenic mice expressing the human Menkes gene 24 ATP7A from chicken β-actin composite promoter (CAG) were produced. The transgenic mice 25 expressed ATP7A in lung, heart,...

A novel porous metal fiber/powder sintered composite sheet (PMFPSCS) is developed by sintering a mixture of a porous metal fiber sintered sheet (PMFSS) and copper powders with particles of a spherical shape. The characteristics of the PMFPSCS including its microstructure, sintering density and porosity are investigated. A uniaxial tensile test is carried out to study the tensile behaviors of th...

Technology for immobilization of biomass has attracted a great interest due to the high sorption capacity of biomass for sequestration of toxic metals from industrial effluents. However, the currently practiced immobilization methods normally reduce the metal sorption capacities. In this study, an innovative ion-imprint technology was developed to overcome the drawback. Copper ion was first imp...

The composite framework of graphitic carbon nitride (gCN) supported copper nanoparticle can act as a high-performance photoreactor for the synthesis of 1,2,3-triazole derivatives under light irradiation in the absence of alkaline condition. The photoactivity of gCN originates from an electron transition from the valence band to the conduction band, in the presence of photon energy, and the hot ...
