Synthesis of Cu/Cu2O nananoparticles by bipolar electrolysis method for electrocatalyst in ethanol oxidation reaction
Abstract. Cu/Cu2O nanoparticles were successfully synthesized using the electrolysis method and a bipolar pulse power supply. The effect of pulse amplitude on the properties of samples was investigated. The phase analysis by XRD showed the presence of both Cu and Cu2O crystals corresponding to cubic structure. SEM images also showed the cubic sh...

Structural, electronic and mechanical properties of few-layer porous nanosheet from spheroidal cage-like ZnO polymorph
Abstract: The low-dimensional II-VI group semiconductors have recently emerged as interesting candidate materials for the tailoring of two dimensional (2D) layered structures. Herein, a series of the cage-like nanoporous composed of spheroidal hollow cages (ZnO)12, cutting from the high symmetrical cubic SOD cage-like polymorph as building block...

Condensate density of a bose gas confined between two parallel plates in canonical ensemble within improved hartree-fock approximation
Abstract: By means of Cornwall-Jackiw-Tomboulis (CJT) effective action approach, the condensate density of a dilute Bose gas is investigated in the canonical ensemble. Our results show that the condensate density is proportional to a half-integer power law of the s-wave scattering length and distance between two plates. Apart from that, these qu...

Streaming potential coefficient measurements in porous rocks saturated by divalent electrolytes
Abstract: Streaming potential in a water-rock system is generated by the relative motion between water and solid surfaces and is directly related to the existence of an electric double layer between water and solid grain surfaces of porous media. The streaming potential measurements have great potential in geophysical applications. Most porous r...

Titanate tubular loaded diatom fabricated by a facial hydrothermal method for photocatalytic enhancement under visible light irradiation
Abstract: In this study, homogeneous titanate tubular (TNT) and diatom/TNT composites (D/TNT) were prepared by a facile hydrothermal method. The crystalline structure and morphology of the synthesised samples were studied by X-ray diffractometry (XRD), Raman spectroscopy, Transmission Electron Microscopy (TEM). Furthermore, the photocatalytic ac...

Fabrication of ba doped LaMnO3 nanomaterials by microwave combustion method
Abstract: The major energy sources that human are relying on are fossil fuel and it is exhausted day by day. Furthermore, exploition and usage of fossil fuel also bring in many negative impacts on environmental polution. Solid oxide fuel cell (SOFC) has been considerred as a potential solution for such environmental and energy problems. Seeking ...
