Structural and physicochemical properties of nickel manganite NiMn2O4-delta synthesized by sol-gel and ultra sound assisted methods
(2016)
In this work we present the structural, magnetic and surface characterization of the ceramic nickel manganite oxide NiMn2O4-delta synthesized by two methods: sol-gel and ultrasound-assisted sol-gel using nitrate salts as ...
Hydrogenation of sodium hydrogen carbonate in aqueous phase using metal/activated carbon catalysts
(2018)
The catalytic hydrogenation of sodium hydrogen carbonate in aqueous phase (NaHCO3) to produce sodium formate (or formic acid) on activated carbon-supported metal (Pd, Ru, Ni, Co and Re) species at 25 degrees C and 1 bar ...
Solid-state synthesis and characterization of alpha-fe2o3@zno nanocomposites with enhanced visible light driven photocatalytic activity
(2018)
The -Fe2O3@ZnOx (x=25, 50 and 75mol%) nanocomposites were synthesized by solid-state method. The formation of nanocomposites was confirmed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy and UV-Visible ...
Magnetic and electrical characterization of nickel-rich NiFe thin films synthesized by atomic layer deposition and subsequent thermal reduction
(2016)
Nickel-rich NiFe thin films (Ni92Fe8, Ni89Fe11 and Ni83Fe17) were prepared by combining atomic layer deposition (ALD) with a subsequent thermal reduction process. In order to obtain NixFe1-xOy films, one ALD supercycle was ...
Biosynthesis of CdS Quantum Dots Mediated by Volatile Sulfur Compounds Released by Antarctic Pseudomonas fragi
(2019)
Previously we reported the biosynthesis of intracellular cadmium sulfide quantum dots (CdS QDs) at low temperatures by the Antarctic strain Pseudomonas fragi GC01. Here we studied the role of volatile sulfur compounds ...
Dielectric and piezoelectric properties of lead free BZT-BCT/PVDF flexible composites for electronic applications
(2019)
In this study, a lead-free 0.50[Ba(Zr0.2Ti0.8)O3]0.50(Ba0.7Ca0.3)TiO3 (BZT-BCT) ferroelectric powder was prepared and used as a filler to fabricate 0–3 connectivity ceramic-polymer composites using polyvinylidene fluoride ...
