Recycling and reusing spent lithium-ion batteries (LIBs) have gained a lot of attention in recent years, both ecologically commercially. The carbon nanotube-loaded CoFe2O4 (CoFe2O4@CNTs) composite was made using solvothermal technique utilizing wasted LIBs as the starting material nanotubes support, it used an efficient peroxymonosulfate (PMS, HSO5−) activator to degrade chloroquine phosphate (...

in this work, cofe2o4 nanoparticles have been prepared by co-precipitation technique. the synthesized cofe2o4 nanoparticles were applied in the preparation of cofe2o4/polyacrylonitrile fiber nanocomposites by the electrospinning process. the prepared nanoparticles and nanofibers were characterized using the scanning electron microscopy (sem) and x-ray diffraction methods. the results manifested...

Here, we report a spontaneously formed nanolamellar BaTiO3–CoFe2O4 bicrystal. 11̄0 interfaces join the BaTiO3 and CoFe2O4 single crystalline periodically arranged lamellae that have a common 111 direction. The superlattice of approximately 2 nm wavelength is magnetoelectric with a frequency dependent coupling coefficient of 20 mV/Oe cm at 100 Hz. The BaTiO3 component is a ferroelectric relaxor w...

In order to meet the growing demand for sustainable and renewable energy, significant processes have been achieved in energy harvesting field recent years. Due its strong polarity property superior mechanical characteristics, polyvinylidene fluoride (PVDF) serves as most attractive material a liquid-solid triboelectric nanogenerator (LS-TENG). PVDF-based TENG has come long way thus far. Hence, ...

In this study, we report the synthesis and application of mesoporous CoFe2O4@MIL-100(Fe) hybrid magnetic nanoparticles (MNPs) for the simultaneous removal of inorganic arsenic (iAs). The hybrid adsorbent had a core-shell and mesoporous structure with an average diameter of 260 nm. The nanoscale size and mesoporous character impart a fast adsorption rate and high adsorption capacity for iAs. In ...

sio2-coated cobalt ferrite (cofe2o4) nanoparticles were obtained by the hydrolysis of tetraethylorthosilicate in the presence of cofe2o4 nanoparticles in co-precipitation. the effects of sio2coating on the magnetic properties of cofe2o4 nanoparticles were investigated. the structural, morphological and magnetic properties of as-prepared sample were characterization by x-ray diffraction (xrd), f...

cofe2o4 magnetic nanoparticles were modified by dopamine (da) and ascorbic acid (aa) as anchors. separation of the da and aa using cofe2o4 magnetic nanoparticles have been studied by investigating the effects of ph, concentration of the da and aa, amount of adsorbents, contact time, ionic strength and temperature. the mechanism of adsorption was also studied. the adsorption of da and aa to the ...

Effects of calcination temperatures varying from 400 to 1000°C on structural and magnetic properties of nanocomposites formed by Co-ferrite dispersed in the sol-gel silica matrix using tetrakis(2-hydroxyethyl) orthosilicate (THEOS) as water-soluble silica precursor have been investigated. Studies carried out using XRD, FT-IR, TEM, STA (TG-DTG-DTA) and VSM techniques. Results indicated that magn...

BACKGROUND The Prussian blue analogues represent well-known and extensively studied group of coordination species which has many remarkable applications due to their ion-exchange, electron transfer or magnetic properties. Among them, Co-Fe Prussian blue analogues have been extensively studied due to the photoinduced magnetization. Surprisingly, their suitability as precursors for solid-state sy...
