In this work, at first, nano ZrO2 and Fe3O4/ZrO2 nanocomposite were prepared by sol-gel and co-precipitation methods, respectively. Then, Ag nanoparticles (Ag NPs) were mixed with themin environmentally friendly and mild conditions using C. cyanus flower extract as a reducing and stabilizing agent. The synthesized nanocomposites were characte...

Objectives: Synthesis of hybrid nanoparticles (NPs) and intercalation as prepared NPs inside polymer matrix to fabricate nanocomposites (NC) evaluate the optoelectronic properties. Method: A simple, time consuming solution combustion method was used synthesize silver doped gallium oxide (AgGaO2) NPs. The casting process employed prepare NC films poly(vinyl alcohol) (PVA) with inclusion AgGaO2 n...

A significant carbon diffusion mobility acceleration as a result of cyclic γ↔ε martensitic transformations in iron-manganese alloy is determined by one- and two-dimensional structure defects of ε-martensite with face-centered close-packed lattice. Such defects (dislocations, low angle sub-boundaries of dislocations, chaotic stacking faults) were formed during cyclic γ↔ε martensitic transformati...

Abstract The fumed SiO 2 and Al O 3 oxides with a specific surface area of about 80 m g –1 were used for the synthesis Ni(80)Fe(20)/SiO , Co(93)Fe(7)/SiO Ni(80)Fe(20)/Al Co(93)Fe(7)/Al nanocomposites, numbers between brackets indicate metal content in wt%, being 10 wt% mass catalysts. Catalytically active bimetallic compositions (NiFe CoFe) that modified oxides’ prepared using solvate-stimulate...

[1] Sulfur and silicon are among the expected alloying light elements in planetary liquid iron cores. Structural properties of Fe-27 wt % S and Fe-17 wt % Si liquid alloys at high pressure and high temperature (0–5 GPa/1400–2300 K) are measured by synchrotron X-ray diffraction. Sulfur strongly modifies the local structure of liquid iron whereas silicon has only small structural effects. Fe-27 w...

Abstract Using nanoparticles (NPs) in different industries such as enhanced oil recovery processes increased during the past decade due to its significant effects on wettability alteration and IFT reduction some extent. On other side, ionic liquids (ILs) are proposed a new class of solvents that introduce considerable advantages areas sciences. In this way, hybrid method based NPs ILs is curren...

In this work, separation performance of supported carbon membranes produced from Novolac Phenolic resin as the main precursor and carbon nanotubes as nanofiller were investigated for separation of CO2 from N2 and CH4. Supports were produced by carbonization of Novolac Phenolic resin-activated carbon mixture, and selective layer was coated by dip coating of prepa...

A crosslinker anchoring process was developed to synthesize Fe(3)O(4)/NaYF(4):Yb,Er hetero-nanoparticles (NPs) with dual properties of superparamagnetism and upconversion (UC) emission. After ligand ozonolysis treatment, these NPs could be well dispersed in water.
