چکیده
Abstract Nanocomposites containing different contributions of vanadium oxide (V 2 O 5 ) and magnetite (Fe 3 4 modified with manganese (Mn) ions were fabricated upon the formula xMn 0.4 Fe 2.6 /(1-x)V 5, whereas x = 0.0, 0.2, 0.4, 0.5, 0.6, 0.8, 1.0. The obtained compositions characterized their structure, morphology, besides magnetic susceptibility. TEM micrographs depicted that V was formed as rod shapes diameters 20–30 nm length 450 nm, while Mn–magnetite configured in ellipsoidal dimensions 25–40 nm. Moreover, Maximum height roughness(R t changed from 507.0 to 220.6 skewness (R sk increased 0.104 0.122 for ( 1.0), respectively. Furthermore, Curie Weiss constant (?) 830 890 K then decreased 520 K, 1.0, photo-activated antibacterial activity examined showed inhibition zone significantly by increasing content well it also dark light conditions.

Hence, nanocomposites can be suggested a deep investigation highlighted disinfection water treatment applications.

Sol–gel derived PZT films doped with vanadium pentoxide
The present research investigated the sol–gel preparation, dielectric and ferroelectric properties of PZT films doped with 5 mol% vanadium oxide. Stable PZTV sols can be readily formed, and homogeneous, micrometer thick and pinhole-free PZTV films were obtained by using spin coating followed with rapid annealing. The X-ray diffraction patterns revealed that no parasitic or secondary phases were...
متن کاملElectrical quadruple hysteresis in Pd-doped vanadium pentoxide nanowires due to water adsorption.
Humidity-dependent current-voltage (I-V) characteristics of Pd-doped vanadium pentoxide nanowires (Pd-VONs) were investigated. Electrical quadruple hysteresis (QH) was observed and attributed to the large amount of water molecules adsorbed on the nanowires. Using QH in Pd-VONs, the reaction of water with PdO was interpreted as the water molecules are desorbed and then dissociated with increasin...
