This study attempts to obtain and test the bioactivities of leaf extracts from a medicinal plant, Geranium wallichianum (GW), when conjugated with zinc oxide nanoparticles (ZnONPs). The integrity extract-conjugated ZnONPs (GW-ZnONPs) was confirmed using various techniques, including Ultraviolet–visible spectroscopy, X-Ray Diffraction, Fourier Transform Infrared Spectroscopy, energy-dispersive spectra (EDS), scanning electron microscopy, transmission Raman spectroscopy. size approximately 18...
Abstract The (1 – x )BiFeO 3 ‐ PbTiO (BFO‐PTO) perovskite solid solution has great potential for being used in practical devices, as it exhibits significant ferroelectric response at its morphotropic phase boundary (MPB). However, the conduction, particularly high electrical leakage currents that BFO‐PTO films show room temperature, deteriorates their functionality. This is mainly associated with presence of multivalent iron along A‐site and oxygen vacancies. Here, solution‐derived thin have...
Multiferroic (BiFeO3)1−x-(PbTiO3)x (1−x)BF−xPT thin films exhibit very high electromechanical properties in the vicinity of morphotropic phase boundary (MPB), making them important candidates for use several modern device applications. However, preparing high-quality is challenging due to conductivity caused by oxygen vacancies produced during synthesis process. This study aims understand effect size and porosity density on electrical films. A series solid solution were fabricated using...
Simple and cost-effective procedures for the direct integration of ferroelectric perovskite oxides into Ni structures are necessary to realize related multifunctional metallic microelectromechanical systems, such as dual-source energy harvesters. This is especially difficult in case lead-containing morphotropic phase boundary materials high piezoelectric response because two components thermodynamically incompatible formation NiOx or oxide reduction takes place depending on processing...
We report on how Co substitution of the Fe sites pseudobrookite (Fe2TiO5) influences crystal structure, high-temperature electric permittivity, impedance, electronic magnetic, and optical properties via experimental theoretical investigations. The phase contains two types octahedral sites, atoms reside type while Ti others replacing with can have a huge influence one or more physical that render material useful for solar energy applications. X-ray diffraction permittivity/impedance were...
