The magnetite (Fe3O4) – agar nanocomposite was prepared by co-precipitation of Fe (III) and Fe (II) ions for the first time. The obtained samples were characterized by x-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy and transmission electron microscopy. FT-IR results confirm the formation of Fe3O4 nanoparticles...

Natural mesolite type zeolite was collected, modified by sulfuric acid treatment and characterized by using Powder-X ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR).Temperature programmed ammonia desorption (NH3-TPD), Brunauer-Emmer-Teller (BET) surface area analysis.  Modified dealuminat...

phenytoine derivatives were synthesized , via the pinacol condensation with thereaction of 1,3- diphenyl- propane- 1,3- dione (benzyl) analogs with urea or thioureain presence of slica gel and solid KOH as Solid phase catalyst in the mortar / pestle atroom temperatures. The reaction was completed at short reaction times (approximately15min) and pure products were obtained with high yields (81-9...

Here, fundamental aspects affecting template-assisted engineering of oxidase-associated peroxide oxidation co-catalysis the modeled microanalytical system based on hybrid palladium nanoparticles (Pd-NPs) with tailored functional properties were studied. By an accurate tuning and validation experimental setup, a modular Pd-NPs-doped one-pot/one-electrode amperometric nanobiosensor for advanced m...
