Fabrication and structural characterization of bismuth niobate thin films grown by chemical solution deposition Abstract: Bi3NbO7 (BNO) thin films were deposited on Pt/TiO2/SiO2/Si (100) substrates at room temperature from the polymeric precursor method. X-ray powder diffraction and […]
Glucose Biosensor Based on the Hexacyanoferrate 11-Mercaptoundecyl-N ‘,N ”,N ”’-trimethylammonium/6-(Ferrocenyl)hexanethiol Abstract: An amperometric glucose biosensor based on on hexacyanoferrate 11-mercaptoundecyl-N’,N”,N”’-trimethylammonium (HMA)/6-(ferrocenyl)hexanethiol (FT)/GOx modified gold electrode was fabricated and evaluated. The GOx/HMA/FT/Au electrode was characterized using cyclic […]
Crystallinity, morphology and high dielectric permittivity of NiO nanosheets filling Poly(vinylidene fluoride) Abstract: Composite films based on Poly(vinylidene fluoride) (PVDF) polymer filled with Nickel oxide (NiO) nanosheets were prepared via the solution casting method. The […]
Electrical and mechanical characterization of a flexible conducting composite Abstract: Composite films made of poly(vinylidene fluoride) (PVDF) and conducting particles of carbon black (CB) were prepared using a hot press. Using different volume fractions of […]
Tracking iron oxide nanoparticles in plant organs using magnetic measurements Abstract: Common bean plants were grown in soil and irrigated with water solutions containing different concentrations of Fe3O4Fe3O4 nanoparticles (NPs) with a mean diameter close to 10 nm. No […]
Highly Efficient and Magnetically Recoverable Niobium Nanocatalyst for the Multicomponent Biginelli Reaction Abstract: A new magnetically recoverable nanocatalyst was prepared by coating magnetite with niobium oxide (Fe3O4@Nb2O5) by using a simple wet impregnation method. The Fe3O4@Nb2O5 […]
Local electronic structure, optical bandgap and photoluminescence (PL) properties of Ba(Zr0.75Ti0.25) O-3 powders Abstract: Ba(Zr0.75Ti0.25)O3 (BZT-75/25) powders were synthesized by the polymeric precursor method. Samples were structurally characterized by X-ray diffraction (XRD), Rietveld refinement, X-ray absorption near-edge […]
Spectroscopy and electronic structure of Sr2YRuO6 and Sr2YRu0.75Ir0.25O6 Abstract: We study the electronic structure of the Sr2YRuO6 and Sr2YRu0.75Ir0.25O6 compounds using x-ray (resonant) photoemission and absorption spectroscopies. The experimental results are interpreted with first-principles calculations, which […]
Pristine and Al-doped hematite printed films as photoanodes of p-type dye-sensitized solar cells Abstract: We hereby propose a non-expensive method for the deposition of pure and Al-doped hematite photoanodes in the configuration of thin films for […]
Raman signatures of monoclinic distortion in (Ba1-xSrx)(3)CaNb2O9 complex perovskites Abstract: Octahedral tilting is the most common distortion process observed in centrosymmetric perovskite compounds. Indeed, crucial physical properties of this oxide stem from the tilts of BO6 […]
