Abstract Flexible nanocomposite films, with cobalt ferrite nanoparticles (CFN) as the ferromagnetic component and polyvinylidene fluoride–trifluoroethylene (PVDF-TrFE) copolymer ferroelectric matrix, were fabricated using a blade coating technique. Nanocomposite films prepared two-step process; first process involves synthesis of (CoFe 2 O 4 ) sonochemical method, then incorporation various wei...

A feasible and fast method to fabricate hydrogen peroxide sensor was investigated by graphene-manganase nanocomposite carbone paste electrode. In the present work, in first step, the graphene was synthesized by chemical method and in second step, manganese oxide nanoparticle was doped on graphene. graphene-manganase nanocomposite was characterized by FTIR and SEM. The nanocomposite shows a high...

We observed two surface spin-wave modes in ferromagnetic resonance in monocrystalline, epitaxial layers of manganese femte (NEFL). The layers, 2 3pn thick, were obtained by CVD on monocrystalline MgO substrates. In MEFL, observations were performed at room temperature and a frequency of 26.6 GHz. The critical angles for which the surface modes vanish amount to 48' and 37', respectively, for lin...

A series of new magnetically recyclable catalysts (MRCs), Ag-M(1-x)Fe(2+x)O(4) (M = Co, Ni, Mn, Zn) nanocomposites, have been synthesized via a generalized one-pot route, and these materials prove to be efficient MRCs in the catalytic epoxidation of styrene. Characterization by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), infrared (IR) and...

In this study, we used 0.2C-1.7Si-1.9Mn wt% cold-rolled sheet as the experimental material to prepare Q&P sample with blocky microstructures and QQ&P lath-shaped through processes, respectively. The partitioning behavior of carbon manganese in two samples after intercritical annealing were studied. During annealing, occurred, resulting contents being significantly higher than those ferr...

Cobalt ferrite, Copper ferrite and cobalt doped copper nanoparticles have been synthesized characterized using different characterization methods (XRD, FTIR FESEM). The prepared used as promising fillers of the polyvinylidene fluoride (PVDF) polymer. PVDF/(Cu–CoFe2O4, CoFe2O4, CuFe2O4) nanocomposites films via a simple solution casting technique. optical properties piezoelectric response nanoco...

We report on the enhance magnetic properties of synthesized Mg-Ferrite catalyst through microwave-assisted combustion route by making nanocomposite via Zn-ferrite. The gravimetric oil removal capability tests from water at room temperature were performed. Phase impurity and surface morphology which investigated with XRD analysis field emission- scanning electron microscopy, indicate that spinel...

Combination of the surfactant-free nonaqueous sol–gel approach with the microwave technique makes it possible to synthesize Fe3O4, CoFe2O4, MnFe2O4, and NiFe2O4 nanoparticles of about 5–6 nm and with high crystallinity and good morphological uniformity. The synthesis involves the reaction of metal acetates or acetylacetonates as precursors with benzyl alcohol at 170 C under microwave irradiatio...
